How to choose the right solar panels: a guide
If you are among the many homeowners that decide to invest in solar panels, you will eventually face the challenge of finding the most suitable ones. What are the most important features to look out for? We have put together a guide for you in order to provide some guidance.
There is a variety of reasons for investing in solar installations for your home. The major one is the fact that it allows you to contribute to the production of the power you require, or perhaps even to self-sufficiently produce it entirely on your own. Yet how do you select the right solar panels for your rooftop? Here is a guide.
Different types of solar panels
There are three main types of solar panels to differentiate. Thin-film solar panels stand out due to their smooth surface and extremely thin layer of semi-conductors, which produce the electricity. Albeit their efficiency is below that of other panels, such as crystalline panels, the revenue per kilowatt is remarkably higher, as thin-film panels are more resilient. As a result, while other panels’ efficiency suffers greatly when exposed to heat (producing up to 25% less), thin-film solar panels lose two thirds less productivity. Furthermore, they are a very flexible solution, as they work well with low light and thus do not require a sun-orientated position.
Bifacial solar panels, on the other hand, stand out as they absorb light from both sides. As the panels are equipped with a transparent plastic sheet (or, alternatively, a glass pane) on their back, they can absorb reflected light. If mounted in a bright surrounding, the yield increase can be as much as 25%.
The probably most classic solution are crystalline solar panels. While they generate a higher electricity yield, their production is also more costly due to high-quality materials and a longer production process. There are two different types: polycrystalline and monocrystalline. Polycrystalline solar cells achieve up to 20% yield and panels as much as 18%. Meanwhile, monocrystalline cells generate up to 23% and panels as much as 19%. Positioning is crucial, as crystalline panels can easily overheat. Hence good ventilation is essential.
Once you have decided on a type of solar panel, make sure to keep the following ideas in mind to ensure a smooth installation process.
Firstly, leave the installation to professionals. Not only will they complete the process efficiently, rest assured they will find the perfect equipment, such as storage batteries, to go with your panels as well.
Moreover, make sure to choose a well-established brand as their products are often better engineered due to great experience and have received all necessary certifications. While this might mean a higher price, the extra investment will pay off and you will soon be able to benefit from your solar power.
