Solar Power Works in any Weather
Sunny – Foggy – Cloudy
Solar panels work just fine in ambient light and will produce significant energy in the fog or on overcast days. In fact, solar panels are actually more efficient at cooler temperatures than hot ones. Although this might seem out of whack, consider that solar panels on a rooftop in cool, foggy San Francisco produce only one percent less electricity than one in nearby Sacramento, where it’s sunny and hot.
Our Experts Match a System to Fit Your NeedsClouds or foggy conditions are not something you need to be concerned about. Overall performance of roof-top solar panels is not dependent on a day to day, but rather, solar panel performance is rated as an average. The average of power producing days is what is used to design the proper size system to meet your needs. Our solar advisors know how to correctly size your system based on your location and climate. Our solar experts use “insolation tables” that organizations like the National Renewable Energy Laboratory produce show figures for particular areas that include factors like fog, clouds and rainy days. If you live in an exceptionally overcast location, you may require a slightly larger solar system than someone who lives in a place that is typically sunnier
Shade and Home Solar Power
While clouds and fog can actually improve a solar panel performance at times, shade is a different story. Actual shading of the sun by trees or nearby buildings can have a negative effect on the performance of your home solar panels. However, shade on your roof top does not always completely rule out solar power. The orientation of your home and where and when your roof is shaded all play into the overall performance of your solar panels. Getting a home solar battery can help with a solar system's performance as well. Our solar advisors will review satellite images of your home and determine the feasibility of home solar power on your house. Also in some areas local and state laws have been passed to ensure your access to the sun’s rays. The State of California, for example, has been very active in passing legislation to guarantee a person’s right to harvest the suns energy to power their home. Our Solar professionals are fully versed in all the state and local rules concerning solar rights in your area. Contact us and we will take care of all the details for you.
