Why do solar panels produce more in summer and solar panels produce less energy in winter than in summer?
Solar panels produce more energy in summer for several reasons:
- Longer daylight hours: During the summer, there are more daylight hours, which means that solar panels have more time to convert sunlight into electricity. In some parts of the world, there can be up to 14 hours of daylight in the summer, compared to as little as 8 hours in the winter.
- Sun's higher position in the sky: The sun is higher in the sky during the summer, which means that its rays are more direct and concentrated. This allows solar panels to capture more sunlight and generate more electricity.
- Clearer skies: Summer days tend to be clearer with less cloud cover than winter days. This means that there is less interference from clouds, allowing solar panels to receive more sunlight.
While solar panels are less efficient in the winter due to colder temperatures, they can still generate a significant amount of electricity. In fact, some solar panels are even more efficient in the winter because they are not operating at peak heat.
According to bostonsolar.us and thepowerfacts.com, solar panels produce more energy in the summer and less in the winter due to several factors:
Overall, while solar power typically is stronger in summer due to longer days and more direct sunlight, a few other factors can affect how much electricity your panels produce during this time of year.
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. During the winter, solar panels will produce an average of 50% less energy compared to the summer. Less output is produced in the winter because the panels have less exposure to the sunlight. They will still work during the winter, but the output will be much larger during the summer months with additional sunlight. However, in summer months we have longer days which mean more sunlight. For this reason, your solar production will be higher in summer. In addition to this, there are also other factors to consider such as orientation and tilt angle. Summer brings with it longer days and more sunshine, making it the peak solar season. According to CSIRO Energy Centre, the amount of solar energy that can be generated on a clear summer day is almost double the amount in winter. So long as sunlight is hitting a solar panel, it will generate electricity. Any diminished output during the winter months will primarily be due to heavy snow and shorter daylight hours.
