Are you looking for a suitable solar panel for your South African home or business? Choosing the right solar panel is a big decision, so you shouldn’t take it lightly. Otherwise, you stand to lose money and peace of mind.
With so many brands and models available on the market, how do you choose the best one?
Now, this guide exists to answer that thoroughly. Below, you’ll find the most important factors to consider when selecting solar panels, a detailed walk-through of the 7 best solar panels dominating South Africa’s energy market, and trusted channels that sell them.
Let’s begin!
How to pick out a great solar panel
When you’re comparing solar panels, here are the key specs you should focus on to make the best choice for your needs:
Rated power (Pmax): This tells you the maximum power a panel can produce under ideal conditions, measured in watts. It helps you understand how much electricity you can expect.
Efficiency: This percentage shows how well the panel converts sunlight into electricity. Higher efficiency means more power from less space.
Warranty: Look at how many years the manufacturer guarantees the product and its performance, giving you peace of mind.
Degradation rate: This indicates how much the panel’s output drops yearly, so lower rates mean longer-lasting power.
Temperature coefficient: This tells you how much power the panel loses as temperatures rise above 25°C. Panels with a smaller negative number perform better in heat.
Dimensions and weight are essential for planning your installation and ensuring your roof or structure can support the panels.
Mechanical load rating: This shows how much wind and snow pressure the panel can handle without damage, which is crucial for durability in harsh weather.
Understanding these specs allows you to pick solar panels that fit your energy needs, space, and local climate for the best long-term results.
