How Does Warm Weather Affect Solar Panels?

As the weather heats up, here are some things to keep in mind about your solar panels.

Many customers worry about their panels losing efficiency in the heat. While it is true that heat affects solar panels, they don’t tend to lose efficiency until it gets above 77 °F. Solar panels have a temperature coefficient, which tells you how much efficiency decreases due to a one degree increase in temperature from the optimum temperature (77 °F). These coefficients tend to be small. For example, the coefficient of SunPower solar panels, which we often use at SGE, is -0.29%. This means that at 80 degrees, the efficiency of the solar panel only decreases by a little under 1%.

Additionally, solar panels actually keep roofs cooler. They absorb heat from the air and can make a roof up to 5 degrees cooler. The maximum temperature that many solar panels can withstand is 185°F, so there is no need to worry about them even on an extremely hot day.

At SGE, when we install solar panels, we leave some space between the panels and the roof. This allows for some airflow and keeps the panels cooler to decrease inefficiency. 

So, as long as you don’t touch solar panels on a hot day (they are very hot to the touch), there is no need to worry about your panels as summer approaches. In fact, you might even find your house and roof to be a bit cooler because of them!

Why you should make the investment in solar today

Massachusetts and Rhode Island currently hosts a variety of solar incentives for homeowners to reduce the cost of buying and installing your own solar panels. These include:

  • Net metering: which gives energy credits back to homeowners when their solar systems are producing more energy than they use in a given day. For example, solar panels often produce the most electricity in the afternoon when energy consumption is low, so net metering allows utility companies to use this energy while it is being produced, then give customers an energy credit back at the going rate that they can use while their panels are not producing. It’s essentially using the grid as a battery. 
  • SMART Solar Incentive (Massachusetts): The SMART program pays customers back a fixed rate per kilowatt hour.
  • Growth Solar Incentive (Rhode Island): The Growth (REG) Program pays customers a fixed rate at 29.6 per kWh for 15 years!
  • 26% Tax Credit: The ITC Federal tax credit was extended (two-years). The ITC for solar customers was originally scheduled to drop from 26% in 2020 to 22% in 2021 and then phase out all together after 2022. But with the recent extension, you can get a full 26% rebate back on the total cost of the system! Make sure to start the process before time runs out and schedule gets full.

Here’s other reasons to go solar for your home:

  • Drastically reduce or even eliminate your electric bills
  • Earn a great return on your investment
  • Protect against rising energy costs
  • Increase your property value
  • Boost U.S. energy independence
  • Create jobs and help your local economy
  • Protect the environment

Federal Tax Credit for 2020 and 2021

Did you know the Federal Investment Tax Credit is Phasing out! This is the most significant financial benefit for going solar. As a turn-key installer, Second Generation Energy will manage the process of getting your solar system installed so you can take full advantage of the 26% Federal Tax Credit WHILE YOU CAN.

Schedule your no cost consultation to see how much you can save by emailing sales@sgegroup.com or calling 508-377-4037.

The federal solar tax credit, also known as the investment tax credit (ITC), allows you to deduct 26 percent of the cost of installing a solar energy system from your federal taxes. The ITC applies to both residential and commercial systems, and there is no cap on it’s value.
