Do Solar Panels Generate More Energy in the Summer?

Aug. 16, 2022

Solar panels produce electricity year round and can power your home or business through every season. They do, however, need sunlight to produce electricity, which means that time of year has an effect on how much power your solar energy system can generate. 

Keep reading to learn more about how solar panels produce energy and how the seasons impact their performance. 

Solar Panels Produce More Electricity in the Summer

You can expect a lot of electricity production from your solar panels in the summer—lowering your summer energy bills and saving you money. Solar panels produce more energy in the summer than in the winter for a couple of reasons: 

1. Longer Days 

The days are longer during the summer, which means your solar panels are exposed to sunlight for greater periods of time and also have more time to produce electricity every day. 

2. More Direct Sunlight 

The sun is higher in the sky during the summer than it is in the winter, giving your solar panels access to more direct sunlight. Solar panels don’t need direct sunlight to work, but they work better in direct sunlight than they do in low-light conditions. 

3. Fewer Overcast Days 

Summer days tend to be clearer with less overcast than there is in the winter, giving your solar panels better access to sunlight. Even though solar panels can still generate electricity on cloudy and foggy days, they tend to generate less when it’s overcast. Solar batteries can help power your home on the days that clouds, mist, and darkness get in the way. 

Because solar panels in Massachusetts produce so much electricity in the spring and summer, you can also rack up a lot of net metering credit by sending your excess electricity to the grid when you have a surplus. When winter rolls around and your solar panels are producing less, the credit you’ve built up with your utility can then carry you through the colder months. 

Solar Panels are More Efficient in the Winter 

Solar panels produce more electricity in the summer, but their efficiency is often better during the winter. 

Solar panel efficiency measures how much electricity a panel can produce from the sunshine that hits it. If a panel is 20% efficient, it means that panel can convert 20% of the sunlight it receives into usable electricity. 

Extreme heat can reduce solar panel efficiency and limit the amount of power a panel can produce. Because of this, solar panels are most efficient on cool, sunny days and can help youtake control of winter energy price hikes!
