Everything You Need to Know About Solar Panels

Perth enjoys more sunny days than many other parts of Australia. Every day, the city receives an average of 8.8 hours of sun saturation. Even in winter, Perth has approximately 118 days of clear blue skies each year. The temperatures here rarely drop lower than five degrees, which means that solar systems are busy all year round.

With the government incentives and other benefits that you can gain with solar, it is easy to see why more and more people install the system for their homes.

What Type of Solar System Should You Install?

For Perth homeowners and those in other Western Australia places, the solar power system should be durable and heat-resistant. With the high temperatures in the city, the panels should continue to work efficiently through the hot summer season. If you are new to solar systems, EasySolar.com.au will guide you on what to choose and all the other essentials that you need to know.

You may want to start with the right type of solar system to buy. We recommend Australian-supported products that come with comprehensive warranties and excellent customer support. High-quality solar systems are those known as Tier-1 products, which EasySolar sells. We trust Tier-1 solar panels, from brands like Jinko Solar, Q CELLS, and Canadian Solar.

Solar Panel Installation Considerations

The installation will depend on the design of your roof. The most crucial detail is which part of the compass your roof is situated on. For Western Australia, such as Perth, Geraldton, Broome, and Albany, the panels are recommended to be installed on the north.

It may sound easy for people with north-facing roofs to have the panels installed at the front of their properties. However, some homeowners do not like the look of the panels at the front where passers-by and neighbours can see them. To solve the issue, EasySolar would use an eastern/western configuration instead.

According to the Clean Energy Council, north-facing panels are the best choice. However, if the north is not feasible for WA homes, the next best option is west.

It is always possible to go for an east-west configuration, which can give you the benefit of the longevity of the day. It means that you will get optimal results from the nice ambient weather in the morning, particularly in WA, peaking in the evening.

The west-facing panels will keep storing energy for a longer period of the day.

How Many Panels Should You Install?

The number of panels to buy will be based on how many your roof can handle. Your installer needs to provide a suggestion for the panel layout based on the look and size of your roof. EasySolar provides the details you need, along with some recommendations when we quote our price.

A local company should be your first choice when it comes to hiring an installer. EasySolar caters to Perth and WA homeowners. We can easily visit homes to figure out the right configuration for people’s roofs. It helps to examine the roof before the installation, saving you time and money that you would have paid the installer even if the panels are not right for your roof.

How Much is the Return on Investment When Going Solar?

One of the most common questions when it comes to switching to solar is the return on investment. The short answer is that it is relative to the system that clients purchase, as well as their consumption. It should be noted that just because you have a solar system does not mean you can start using power unlimitedly.

To know if you are getting the worth of your investment, you should utilise the power that the system produces. Turning on power-hungry equipment and appliances, such as your spa or pool filters, should only be done when during peak times for solar. The reason behind this technique is that solar will absorb the costs of running these appliances.

The actual ROI depends on how much you pay for your solar system. If you pay a lesser amount for it, but you save a lot on power bills, your ROI is greater than expected. You should use the system smartly. Expect your investment to pay off in two and a half to three years. However, the savings are pretty much immediate.

EasySolar.com.au clients with bills of up to $600 started to have lower consumption in the summer, paying only $100 after solar installation. Another client with $540 from the previous bills only paid $148 after solar even though he used his pool pump for most of the day. His friend with almost the same power bill went down to $78 because he did not have any power-hungry appliance. In other words, it does not take long to save money and get the investment back.

Roofing and Inverter Requirements

Some roofs have different needs and limitations, such as tin roofs with different screw lines than those with troughs and peaks.

Remember, there are requirements for roofs. The first step to going solar is to inspect your roof first. Here are things to keep in mind:

  1. Direction
    • North: As mentioned, your roof should face north so that you can get the most electricity out of
      all the choices. It is best for those who usually are at home during the day. You can switch
      your power source on-demand, such as when you use washing machines, pool filters, and clothes
      dryers among others. If your roof allows it, you should choose north to get the environmental
      benefit as well.
    • West: If it is not possible to go with a northern orientation, west is the next best option.
      Compared to the north though, expect the panels to produce about 12% less electricity. However,
      the panels can produce more power in the afternoon, reaching their maximum output an hour and a
      half after noontime. Additionally, just before sunset, it will generate electricity about a
      quarter of the maximum. West is ideal for those with air conditioning units to be used during
      the summer, making it an excellent option for Perth homes as well.
    • East: As with west, east-facing panels produce 12% less electricity. However, they generate more
      electricity in the morning, suiting those households that consume electricity during the day.
      For instance, if you use a lot of electric heating in the winter mornings, an east configuration
      may work for you. If you are out of the house in the afternoon, it may also be suitable.
    • South: For those in Western Australia and most parts of the country, the south is the worst
      direction of all. It is a massive mistake, just like you are installing the panels upside down.
      You will produce almost 30% less energy compared to north-facing panels. It gets worse if you
      have a steep roof.
    • Combinations are becoming popular though. For instance, north-west panels will produce 5% less,
      but it is almost insignificant. North-east panels will also produce the same amount and are
      suitable for those who need electricity during the day.
    • East and west orientation will produce less output than the combinations mentioned above.
      However, it is more efficient with the benefit of producing constant electric production during
      the day. If you have a steep roof, this configuration gets better.
  2. Space
    • If you have enough room on your roof, installation should not be a concern. Roofs, however, should not have any obstruction, including skylights, chimneys, and others. You can install anywhere from 20 to 30 panels, but EasySolar recommends to install as many as you can – reasonably, of course.
    • Thanks to the reduced cost of solar systems and the high price of electricity, many homeowners are looking forward to going solar. Add to that are the feed-in tariffs and the benefits you can get, it is easy to commit to solar installation.
    • When determining how many panels you can actually install, choose the number that can fit on your roof and the amount that the Distributed Network Service Provider (DNSP) permits households to install in your area.
    • Most homes can go with a 6.5kW system because they use single-phase power. If you have a large rooftop, however, and you have a three-phase property, you can always go for a much larger size.
  3. Type of Roof
    • If your roof is slanted, the panels will be installed differently from those with flat roofs. Either way, the panels should not be in the gutter. It should also not exceed the ridge on the top side, which is why some installations are landscaped and not in portrait orientation.
    • Roofs that slant at least 30 degrees are the best candidates for solar installation. If you have a flat roof, it does not mean that it cannot accommodate solar. However, you may need a mounting system to help you out.
    • Solar panels can also be attached to various surfaces, including shingles, which are the easiest material to work with. If you have a roof made of clay or slate, it can be a problem since these materials are prone to breakage. You may need to be extra cautious when installing a PV system.
    • Another thing to worry about is the age of the roof. It can be an issue if your roof is showing signs of aging, such as lifting or cupping. It is best to replace portions of the roof first with these problems before PV installation; otherwise, it will be costly and time-consuming.
  4. Shading
    • If the roof spends a lot of time in the shade, it does not mean you cannot enjoy the benefits of a solar system. Ideally, the panels should get sun exposure from 9 AM to 4 PM or at least six hours of uninterrupted sunlight.
    • Technology has evolved though, which is why it is no longer a big of a deal if the solar panels are shaded by nearby trees, buildings, and other obstructions. Panels with 120 cells in a 60-cell frame, for instance, have many diodes that allow more flexibility in performance. However, you can expect a reduction in electricity production.
    • The best way to determine if your roof and location are best for solar panels is to call the experts at EasySolar. With our experience, it is easy for us to judge what you can fit and where. We keep the arrays nice and tight together, so you have cables linking the panels efficiently. It is all about the panel layout. You can get the installers to do a measure up as well. Some homes require our pros to do a site inspection.
  5. Inverter Requirements
    • A quick detail about inverters concerning your panels is that the inverter capacity depends on the average number of panels you have. Typically, the best option is to go for a 6.6kW package with a 5kW inverter and 24 panels. This package can provide you with excellent power for the day.
    • For a single-phase property, you need a single-phase inverter. If you have a three-phase property, use three-phase inverters. It can get costly, but these inverters are a requirement.

Installation

Residential Solar Panel Installation & What to Expect

Once you have decided that you want to have a solar system on your roof, the next step is to call EasySolar. Here’s what can happen:

  1. A client calls and we schedule an onsite assessment.
  2. You can send us your application a copy of the power bill, along with the date of birth of the person named on the bill. Provide a copy of the front and back of the Synergy bill.
  3. We will take care of the approvals. You can be confident in having your solar system done within 14 working days. Homeowners are required to have their metre configured since it has to be bidirectional, which should be done before the installation.
  4. During the day of the onsite assessment, someone should be at home, whether it is the owner, the person who called, or someone with authority on the property. This individual should sign the required paperwork and the STCs on the day of the inspection.
  5. With our staff in your home, you will already have an idea of our suggested layout. It can change after performing a complete site check-up.
  6. We will discuss any adjustments that should be done to achieve the maximum results. For example, our suggestion was to use a north-east configuration but the assessment showed north-west orientation is better, you will know right away.
  7. We double-check your electrical board to make sure it has an electrical switch to conform to the law and we can fit the actual breaker in there. Having your solar in your property means that you have a second power source on your roof, which means you need to comply with all these requirements.
  8. After these steps, we will tell the client other important details, including how the array will be placed.
  9. The installation will carry on.
  10. Three to four hours later, the system will be up and running.
    We try to make sure everything will be done on time, which is crucial not just to the client but to us as well.

Warranties

Warranties of Solar Systems

There are hundreds of panels and inverters on the market. Some have a minimum warranty, but others have better offers. For inverters, the industry standard is five years. You can always purchase extended warranties, which will allow you to prolong the guarantee of the product.

It is not rare to find companies offering ten years warranty, which shows they have good faith in their product.

On the other hand, panels have more extended warranties, which are divided into two categories. The first one is the warranty on the assembly, which is about ten years long. You can find other manufacturers offering up to 12 years of warranty, but there are a few with 15 years in total.

The second warranty category is for the performance of the panels. The industry standard is 25 years, which means that the panels will start to reduce inefficiency, usually 80% less, once they reach the age of 20.

Always speak to the salespeople before you purchase. This way, you get advice on which ones are the best. Some have better warranties, but they can be expensive. However, it is an ordinary matter with any product, not just inverters and panels.

To avoid any warranty issues, make sure that you follow the guidelines of the manufacturer. Companies require you to make sure the panels are checked once a year and cleaned regularly to prevent nullifying the warranty. You can hire people to clean or avail a maintenance program. If you like to DIY, you can wash it with a hose, no need for a squeegee.

Tier 1 Panels

What are Tier 1 Panels?

The Clean Energy Council created stringent stipulations to ensure that only those companies with the best panels will be approved by authorities and experts. Panels were then rated tier 1 to tier 3 with tier 1 being the highest.

Bloomberg New Energy Finance (BNEF) presents a list of the top panels, consisting of about 22 panels every quarter of the year. To get to the list and be named one of tier 1 solar panels, there are requirements to fulfil, including:

  • Investing in research and development
  • Having a stable and excellent financial standing
  • Having a reputable history and longevity with at least five years of existence in the industry
  • High Worldwide sales
  • Being under a respectable company
  • With minimal human contact during the manufacturing process
  • Having control of the resources, they utilise in producing their panels
  • With sustainability in mind when designing their products

Some of these brands include Canadian Solar, Jinko, ET Solar, Q CELLS, LG, and Risen. These brands are mainstays in the list of panels that EasySolar sells and trusts.

Buyback Scheme

What to Know About Renewable Energy Buyback Scheme (REBS)

Those living in Perth, as well as those in the southwest region of Western Australia, use Synergy, which is the electricity provider. Since the cut on the feed-in tariff, solar system users will get a total of 7.135 cents for every kilowatt-hour they have given back to the mains grid.

Western Power through its billing arm, Synergy, will pay you a tariff when you send power that you did not use in your house back to the grid. For some people, this may not sound like it is worth it because the tariff is equivalent to just seven cents. However, if you take the time to do the maths, it can certainly be worth your effort.

For you to understand better, here is an example:

If you have an extensive system and you send back 1100 units, you will get a credit back on your bill. This amount is almost the same if you have to purchase 300 units in the nightfall. You get $0.07, and you send back 1100 to 1200 back to the grid. It is equivalent to the money you have to spend if you did not get the credit. Currently, it is around $0.25 to buy a unit.

Another example is for those who rent out their place. If you have solar as your power source, it will benefit you in the long run. Many tenants see how efficient a solar system has become. You can increase your rent from $10 to $20 depending on your location because more and more renters will be glad to occupy your property.

Solar Inverters

What is a Solar Inverter?

An inverter is a piece of equipment that converts the direct current that comes from your roof. Power enters the machine or the inverter and turns it into AC. In Australia, the nominal voltage is 240V.

To be battery-ready, all single-phase and three-phase properties should use hybrid inverters. The problem is that there are only certain batteries that are truly hybrid and only a few companies offer them. Plus, they are quite expensive. For instance, Fronius only has a three-phase inverter and only a suitable battery can be used.

If you have a single-phase property, you may want to choose a Huawei with its single-phase hybrid. Huawei will soon introduce a three-phase hybrid though. For your three-phase property, GoodWe inverters are a good choice but you can only utilise the right type of battery for it, which is HV from BYD.

Since this technology is quite new, most of these products are in their testing phases. This is why many homeowners are still not using batteries. It does not mean though that you cannot benefit from your solar system even if you do not have batteries. It will run just the same and will not cost you extra.

Where to Install Inverters

Unlike panels, inverters are in the garage but never on the side of a north-face house. A particular brand recently removed the digital display of its product because people would install inverters on the northern part of the building, which caused them to burn out.

There were eventually warranty issues, but not because of the units. The problem was with how people installed them. These inverters are rated IP65, meaning they are cyclone proof so they can be installed outside the home.

Rather than being placed on the northern portion of the house, inverters can be installed on the west-face. However, they are better on the east, specifically in Perth.

Metrics in Choosing the Best Inverter

Just like panels, you have numerous inverter choices. Here are some considerations before you choose:

  1. The size of your power bill
  2. Is it usable in Australia? Is it Australian-approved?
  3. How much should your budget be?
  4. What size should you go for?

While there is a rebate and feed-in tariff, your rebate is based on the number of panels you have. If you have a small bill ($200 to $250), you can get away with a 3kw, 13 panels, 3.6kw package. Because the rebate is attached to the number of panels though, the price difference between a 3.6kw and a 6.6kw package is negligible. So why not go for the most that you can?

Synergy, while the feed-in tariff still exists, will pay you for the extra power that you have generated and sent back to the grid. EasySolar suggests that clients get more panels on their roof because they can get credits while they can use more power, especially in the winter when they use a heater.

Another consideration is the type of inverter. A string inverter is the most common type of inverter. All panels are in a string, like a loop. The inputs are at the bottom of the inverter where DC gets connected into what is called MC4s that allow it to operate. This type of inverter is required for on-grid users.

For those who want to be off the grid, they cannot do so in WA. An exception if they live in rural areas where they have no power in their property. Western Power deems it as islanding, which is illegal. You can get as much power as you can and get rid of your bill, which is pretty much equivalent to going off the grid.

All About Batteries

Rooftop solar arrays, for the most part, are connected to the grid. However, it does not always have to be that way. With solar batteries, you can produce more energy than you can consume. The difference is that you do not need to feed the electric power back to the grid.

When the panels do not produce enough energy for your appliances and other pieces of equipment, you can still have power from the grid. However, if you have a solar battery installed as part of your solar system, you can store extra solar power and keep it there. There is no need to send it back to the grid.

When you have excess power, you can use it to charge your batteries instead. You can then utilise this stored power if the panels do not generate as much energy as required. An example is when it is cloudy, and you need more power than what your system has acquired throughout the day.

A solar battery can also be used as a backup for your home if there is an electrical outage.

There are two main options with batteries:

  • You have the inverter, and the excess goes to charge the batteries. When the batteries are full, the power goes back to the grid, and you get a feed-in tariff.
  • You should have a facility within the batteries for circuit protection. If the grid ever drops out, you can still have power, thanks to the battery. It will not last for a long time, but it can provide a few hours so that you can accomplish your tasks, for example.

Typically, homeowners use batteries for their lights or to power up their appliances, such as the fridge, pool filters, and other equipment.

How Do Batteries Work?

If your solar panels create more power than what you need and use at home, the excess electricity will go into the grid. There may be times, though when the panels cannot produce electricity, perhaps because of the bad weather. In this case, you can turn to your battery storage when you would normally draw power from the grid.

For many households, they use batteries because of any of the following reasons:

  • Excess solar energy is generated during the day, allowing the homeowner to store it. This energy can be used when the sun is not shining.
  • Some homeowners want to have backup power that they can easily access if ever the grid goes down.
  • Other users want to charge the battery during off-peak times and utilise the energy during peak times.

Batteries are known to make it easy for homeowners to use solar at night. Additionally, they are great as backup power sources. However, some systems do not offer both, although it does make the battery storage more affordable. For those who live in Perth or any major city or town in the country, batteries as backup may not make sense. After all, most people probably do not even remember the last time they had a blackout, including one that lasted for more than a few hours.

Nevertheless, some installers would say that batteries are crucial for your solar system to operate without interruptions.

But How Do Batteries Work?

Batteries would discharge at night and recharge in the morning. If you consume more power than normal, you need to have excess power that you are not using to charge the batteries. Some homeowners in Perth would have a huge bill in the daytime, and you want to charge a 14kW battery, it may not be feasible. You should talk to a professional to calculate your needs and what is suitable for you.

Solar battery storage systems work in two ways. The first one is without backup, specifically a hybrid solar system that does not have backup battery storage. This system is the simplest and most affordable type of storage available today.

Electrically, it will treat the batteries just like it would any other solar panel array. Therefore, the pack plugs straight into the spare input on the inverter.
For the battery integration to work, you need the following:

  • A battery pack that has a high voltage DC output, along with an integrated charger
  • Detailed information on how much power is used in the household to aid in determining when to charge the batteries
  • An inverter to manage the battery’s system, as well as a spare input
  • Wires

It can be a little complex, requiring the help of a real professional who understands how everything works.

The other way is to have solar battery storage, meaning you have a hybrid system with backup. This one is more expensive, and it is performed either by AC or DC coupling. AC coupling involves coupled systems that utilise 240V AC for charging the batteries. It is the more common option, particularly in retrofitting batteries to an already up-and-running solar system.

What to Know About Batteries

One thing to watch out for if you would like to use batteries is getting scammed. An example is you get charged $7,000 for a 1kW battery, which will not do anything for you. If you have a 4kW inverter on your wall and it is at peak production in the night, it needs almost four units to power it for one hour. If you only have a 1kW battery, it will only last 15 minutes. Be sure to talk to an expert and understand the limitations and requirements with batteries.

Another important fact is that there are batteries that you can only use for the specific inverter it is designed for. For example, you have a Fronius battery, which should be paired with a Fronius inverter.

An Enphase microinverter uses an Enphase battery. The product is quite handy and impressive. It is a 1kW battery, but you can string ten in a row.

LG Chem RESU10 is also one of the best products out there. It is a 48V lithium-ion with a 9.8kWh storage system. The RESU10 is an optimised solution for those who want to save energy while delivering high-quality power.

Another product worth mentioning is BYD, which uses HV and LV batteries. GoodWe inverters also work with HV.

Solar Hot Water

Perth and the other areas in Western Australia are abundant in the sunshine. It is only right to utilise the power of the sun to save on energy bills. Solar hot water is generally water that is heated using only the sun’s natural energy.

The method is easy to understand, especially for those who already have a background with solar panels. With solar, thermal collectors, which are large panels, are heated. Energy will be moved through water (or other fluids) into a reservoir tank where it will be stored.

In an average Australian home, water heating is the biggest source of greenhouse gas emissions, with almost 30% of home energy usage. According to the Australian government, homeowners should install a solar-powered hot water system, which can allow from $300 to $700 (or more) savings on power bills every year.

Unfortunately, solar hot water is not affordable. It is why many people use their heaters instead. However, they do not realise the potential savings they can get. It is essential to know how to choose the right solar hot water product to ensure huge savings and efficiency.

How to Choose Your Solar Hot Water System

Heat pumps have been around for a long time, but they are not ideal for residents who do not want to spend a huge amount of money for water heaters. Then, solar hot water systems came along, and they promise to deliver exceptional results without breaking the bank.

A solar hot water system has a series of solar collector panels, as well as a storage tank. Typically, a four-person household would need about four square metres of solar collector, which is equivalent to two panels. A 300 to the 360-litre storage tank is often enough.

A solar hot water system can be mounted on the roof or installed on the ground. While you have several other options to heat water, including gas and electricity, solar is the best way to power up your hot water system. It is the most energy-efficient of all while adding value to your properties. Using solar hot water systems can substantially offset gas emissions and pollution in the country.

The right system can reduce your water heating bill by up to 85%. Another benefit is that water remains hot throughout the day. While these units may be pricey, they come with government incentives that lower the price of solar hot water systems.

To choose the best solar heating system for your water, here are the most important things to consider:

  1. Find out how much hot water you require. Select a unit that can fulfil the needs of your family. It should be an active system that has a significant collector if you often use hot water. One way to determine how much hot water you expect to produce is to multiply the number of people in your household by 68.13 litres. Typically, a family of four would use about 270+ litres of hot water for bathing, cleaning, cooking, and others.
  2. Consider your location. Perth is a sunny area, which means that you can generate a tremendous amount for your water heater even if you have a small system.
  3. Determine your budget. The good news is that solar hot water units do not need to be expensive. They also provide a fast return on investment. You can get estimates first to know how much you need to spend.

EasySolar presents the iSTORE Hot Water System Package that boasts air-to-energy technology. It is designed in Australia for Australians, making it suitable for sunny Perth and other Western Australia locations.

Instead of using inefficient electric units and gas burners that waste your money, iSTORE is the best solution for any household. This product eliminates heat energy from the air, storing it in a vitreous enamel tank that has been approved by Australian standards. The iSTORE will only use 4kW/h energy to heat 270 litres of water. Compared to electric or gas, it is a very small amount. Other units typically need almost 15kW for the same amount of water.

ISTORE is the best and most affordable option that you have today. Our experts at EasySolar trust this product, which is why you are guaranteed that you can never go wrong with it.

This system is so useful that the Australian Government gives out STC incentives, along with the local state government rebates. This way, homeowners will find it even more encouraging to use iSTORE over electric and gas hot water systems.
