Do Solar Panels Work on Cloudy Days?
The simple answer is a reassuring yes. Your solar array won't suddenly shut down the moment a cloud passes overhead. Thanks to the photovoltaic effect, solar panels can convert both direct and indirect sunlight into usable electricity for your home. On overcast days, this indirect or diffuse sunlight is what keeps the power flowing. In fact, solar panels still generate electricity on cloudy days from this light, although the total power output is often reduced to 10-30% of their maximum capacity according to energy researchers. To put this in perspective, during the total solar eclipse of August 21st, 2017, the extensive solar array at The University of Toledo's Scott Park Campus saw its energy generation drop significantly, losing about 1,170 kilowatt-hours (kWh). While a substantial dip, this loss represented less than 0.1 percent of its total annual production, demonstrating how even extreme darkness is just a temporary blip in the long-term energy yield as noted by university physicists.
What is the biggest drawback of solar panels?
Historically, the biggest drawback has been intermittency—the fact that panels don't produce power at night and have reduced output in certain weather. However, the rapid advancement and decreasing cost of energy storage solutions have largely solved this problem. A modern solar-plus-battery system provides reliable backup power during power outages and ensures a consistent energy supply, turning the biggest weakness into a major strength.
Why is my electric bill so high if I have solar panels?
There are a few common reasons your electric bill might still be high after a solar panel installation. It could be due to increased energy consumption in your home, the system being undersized for your needs, or issues with the equipment (like a malfunctioning inverter). It's also possible that it's a cloudy season, reducing solar production. A reputable solar service provider offers system monitoring to track performance and can perform a home energy audit to see if your usage has changed. If you're concerned, contacting your local installer for a system check-up is the best first step.
