Given the recent temperatures of up to 45 degrees in some parts of the country, some people may wonder how heat is affecting their solar panels.

First, we need to understand how solar panels work. Although sunlight and heat are always correlated, these two factors affect the performance of your solar system differently. While heat does not reduce the amount of energy your panels extract, it does affect the way the cells produce energy. This is because solar panels generate energy from sunlight, not heat. The higher the temperatures, the lower the efficiency of your solar modules, which leads to energy losses and a decline in system performance.

Temperature coefficient

The performance of a solar module in relation to a certain temperature or a certain temperature coefficient varies from brand to brand and is important for calculating an exact production level of your solar system. For this reason, it is important to choose the best solar panels for your roof efficiently given the tropical climate of the Philippines. Most solar modules offered by Solaric have a coefficient between -0.35 and -0.5. The temperature coefficient indicates how much electricity a solar panel loses with every temperature increase of 1 ° at temperatures above 25 ° C.

For example, a solar panel has a temperature coefficient of -0.35% per 1 ° C. With every increase of one degree above 25 ° C, the efficiency of the solar module decreases by 0.35%.

Reduction of the thermal effects

The effects of heat on your solar system are inevitable, especially in summer when the heat peaks. This is why it is important to find an experienced and knowledgeable solar supplier who will correctly install solar panels in your roof. The right installer will install the panels at the right angle to ensure that you can still bring in the maximum sunlight possible while a convective air flow can cool the panels. They also give you multiple options for solar panels, inverter brands, and system-sized systems that allow you to fully enjoy your solar system. Another tip is to apply ceramic paints to your roof. These are just a few of the tips you should know to answer the question “How does heat affect solar panels?”
