Guide to Choosing the Right Solar Panels

Post by : Sam Allcock on 08.06.2022

If you’ve decided to install solar panels in your business, there are things you should know beforehand. Buying solar panels, especially for the first time, can be very confusing. Here’s a guide that might help you out.

Types of solar panels to meet your needs

This guide will discuss three different types of solar panels. After reading this section, if you are still unsure what to choose, your commercial solar panel provider can help you make the best decision.

Monocrystalline solar panels for better efficiency

To buy the right solar panels that can give you the best energy efficiency, opt for monocrystalline solar panels. This type works great in converting light to energy due to its high silicon purity. However, it’s costlier than its counterparts. So, if you have a flexible budget and prioritise productivity above everything, monocrystalline solar panels are for you.

Polycrystalline solar panels for greener energy source

If you want the eco-friendliest option, choose polycrystalline solar panels. This type of solar panel uses every inch of silicon material it comes with. What makes it even more desirable is that it is cheaper than monocrystalline panels. However, they are not as efficient, so monocrystalline solar panels are more expensive for a reason.

Additionally, polycrystalline solar panels don’t perform well in hot climates. If your business is based in a region where the temperature exceeds 27°C, this solar panel is not the best choice.

Thin-film solar panels for a low-budget option

Usually, thin-film solar panels are the cheapest option there is. They are ideal for people with simple solar panel needs. However, thin-film solar panels are the fastest to degrade compared to the first two mentioned types. So, expect to meet some repairs after years of using this type of solar panel.

Also, thin-film solar panels often take up more space. Therefore, business owners opting to save space should better check out the next option.

Amorphous solar panels to save space

Opt for amorphous solar panels if you’re searching for a solar panel ideal for a small space. These are smaller than thin-film panels but are more practical. That said, this doesn’t mean they are cheaper. Amorphous solar panels cost more than typical thin-film panels.

This solar panel can provide a high energy-efficiency level by “stacking,” a process that stacks several layers of amorphous silicon cells. It could even become twice as efficient as other thin-film panels.

Temperature coefficient

Another thing to consider when choosing a solar panel is its temperature coefficient. It indicates the heat’s impact on the panel’s operational efficiency. Choose solar panels with a lower percentage of temperature coefficient per degree Celsius.


Most solar panels come with a 25-year warranty. You can tell that a company is confident with its product’s durability when it offers an extended warranty period.

Final thoughts

To sum it up, the type, durability, and temperature coefficient of a solar panel are only some factors to consider when buying solar panels. Knowing that not everyone knows these things, it’s better to have a professional to advise you, so you make better decisions. It could also save you from problems that might occur if you buy the wrong one.
