Solar Panels: What to Know About Their Temperature & Efficiency

Solar energy is gaining so much popularity these days because of the many benefits it delivers to homeowners and business owners. However, the use of solar panels is still relatively new, which has caused many people to question their efficiency. Yet, this only goes to show the interest that solar energy is gaining from the public.

In this article, we will share all you need to know about solar panels, especially about temperature and their efficiency.

The Level Of “Heat”

Many people wonder whether or not solar panels get hot. Yes, the answer to this is that they could get hotter depending on the climate you’re in. First, solar panels absorb sunlight and convert it into electricity, but not all of the sunlight it receives will be converted because some will be turned into heat instead. This eventually results in your solar panels heating up, which can reduce the production of your energy. Solar panels can produce maximum efficiency between 59 °F and 95 °F.

The Generated Heat

Since solar panels convert some of the sunlight into heat, it doesn’t mean that it can heat up a home, but it can somehow cool a home. This is because the solar panels on your roof absorb the sunlight first and convert some of them into electricity, meaning that not much of the sunlight will reach your roof. In turn, this will not overheat your home. Moreover, it can increase your home’s total energy efficiency because it prevents heat from escaping into cooler temperatures at night.

The Ambient Temperature

Ambient temperature, which is the ordinary air temperature, affects the efficiency of the solar cells. As mentioned, the efficiency of the panels will decrease when they get too hot. Because of this, if the ambient temperature is at 100 °F, the efficiency of the panels will be a bit lower than on the day when the ambient temperature is at 80 °F.

The Temperature

Keep in mind that hot or cold temperatures do not influence the energy production of the solar panels. Instead, it depends solely on the light of the sun to produce energy. However, there is usually more efficiency when it’s cold, similar to all electric appliances that work better in colder weather.

The Efficiency Rating

Some panels can reach up to 22 percent efficiency or more, while most produce between 15 and 20 percent. However, this doesn’t mean you should choose the most efficient solar panel for your home because that’s not all that you need to consider. You also need to think about how much space you have available for the panels and their price. If you have a lot of space for the panels, a less efficient solar panel can produce just as much as high-efficiency panels will.


When you know how solar panels produce energy and the factors that affect them, you will be able to make a more informed decision on the number of panels you should invest in. Remember that as much as efficiency is an important factor, it’s not the only aspect you should be on the lookout for. The space and price of the panels are essential considerations as well that you should think about before you purchase them. It’s time to make the switch from traditional electricity to solar, as the benefits you can get from solar energy is unmatchable.
