Most Important Things To Consider While Purchasing Solar Panel For Home

. 4 min read

In the time of global climate change, solar power has emerged as the go-to source of energy for its multiple benefits. Several countries across the globe are now promoting solar power installation for homes to make them more self-reliant and sustainable. With governments providing subsidies and pro-solar power policies, buying solar panels has become more affordable and solar panel installation more accessible.

Solar panels, used to generate electricity using the power of the sun, are photovoltaic cells mounted on a frame that can be installed on the roof-top. They utilize solar power to generate electricity and can power your entire household if done right. But before you go solar, it is important to know things like what are the best solar panels to buy, how to choose solar panels, where to buy solar panels from, solar panel dimensions, its size, and which bidder offers the best price and post-installation services.

While the Australian market is flooded with retailers that provide these services, not all of them guarantee the best results. The best way to get the most favourable services is to find a solar provider that fulfils all your needs at once.

Things to consider when buying solar panels for home

Going solar can be an exhilarating experience for you as it stands to make your home more energy-efficient. But with several companies competing for your money, choosing solar panels that fit the best for your requirement can become a task. So, check out our solar panel guide, where we tell you the most important things to consider before making a purchase.

Solar panel size:

The first thing you need to consider is the solar panel size in Australia and its sustainability. As Australia is in the Southern Hemisphere, solar panels should be installed facing north. So, decide on the solar panel size according to your roof-top that faces north.

Solar panel efficiency:

The amount of output solar panels generate determines their efficiency. The more energy they are able to convert, the better their efficiency. The best solar panel for a home is the one that has a 20 plus per cent efficiency. Systems with average efficiency provide anything between 15-16 per cent, and the ones providing 17-19 per cent are considered above-average.

The durability of solar panels:

One of the most important aspects you should consider before buying solar panels for your home is their durability. Your solar panel should have a high load-bearing capability and the ability to withstand environmental conditions. Since Australia is privy to strong winds, buy solar systems with high wind load and hail protection.

Warranty periods:

Many companies provide a 10-12 years warranty for solar panels and a 20-25 years performance warranty period. Performance warranty means that if your solar system performs lower than what is promised, the retailer will deem it defective and provide you with a replacement. You should ensure to buy solar panels that offer a long warranty period.

Products and items you need to install solar panels at home

Whenever you decide to purchase a solar panel system for your home, below are the four essential products you would need. While several solar panel installers can do the job for you, a little extra knowledge will help you make an informed decision. So, here’s all you should know about them:

Solar panels:

Solar panels can be divided into two categories  - monocrystalline and polycrystalline panels. Experts suggest that both kinds are equally efficient, and buying a good quality product matters more than which kinds you buy. So, the best solar panels for homes are the ones that perform for the guaranteed period and follow the guidelines charted out by Clean Energy Council. As long as these two criteria are met, you are good to go. It’s a given that high-quality products will perform better, but you can choose according to your budget.

Inverter:

Solar panels produce power in DC (direct current) while your home appliances utilize AC (alternating current). The inverter converts DC into AC to be used in your home. Just like solar panels, even inverters are of two kinds – string inverters and microinverters. String inverters sit on your wall and connect to all the solar panels and are best for solar systems that get ample sunlight. Microinverters are attached to each solar panel and are best for systems where one or more panels are partially shaded. Whichever you decide to buy, make sure that you get a good quality product since inverters are the heart of your system that should function well at all times.

Monitoring:

Almost all inverters come with a monitoring option that requires the monitor to be attached to the internet through Wi-Fi or a cable. It provides you with important information about how your system is performing and can flag off if there is an area of concern that needs your attention. It is optional but an advisable add-on.

Mounting:

This is the procedure of securely attaching the solar panels to your roof-top. Again, quality matters here as it is one of the most important processes of solar panel installation. Go for a brand that provides wind protection. You don’t want your solar panels flying off the roof in a storm. Also, look for how many years of warranty the brand provides. If you have a slanted or non-penetrable kind of roof, choose the mounting accordingly. There are suitable options available according to your roof type.

Questions you must ask before finalizing a solar panel installer

No matter what a particular brand promises or offers, never shy away from asking any questions you have in mind. Solar power installation is a big investment, and you have the right to ask as many questions, however many times to the bidder you are going to hand over the job to. Here are a few that you must not miss:

  • Ask them about their CEC accreditation number. It can also be checked at solaraccreditation.com.au
  • How long has the brand been in business, and all details about the owners
  • How many installations has the company done in the past, and what has been the success rate?
  • Do they have any testimonials from their previous clients? If you wish to speak to any one of them, would they be willing for the same?
  • Do they offer a performance guarantee?
  • Do their products meet the standards set by the government of Australia?

Go ahead with the bidder only if you feel satisfied with their answers.

If you are thinking of going solar, this is the best time to do it. Not only is the world waking up to the numerous benefits of home solar panels, but the governments are also pushing to make households solar powered.
