Does Solar Panel Work Well on Cloudy Day?

One of the biggest problems about solar panels is that solar technology doesn't work on cloudy days. Along this line of thinking, since solar panels need the sun to generate electricity, they only work in areas with more direct sunlight. With this article, we'll help you learn more about the effects of cloud cover on solar energy production, and how well solar panels work on cloudy days, so you can make an informed decision when it comes to installing solar panels.

Even the most indirect source of sunlight, solar panels can still generate electricity. They are designed to take advantage of every possible ray of sunlight. This includes generating electricity on partly cloudy and fully cloudy days.

If you've ever gotten a sunburn while working outdoors, you know that the sun's energy can still penetrate the clouds, even with clouds covering them. Likewise, even if you can't see the sun, sunlight can still reach your solar panels and generate energy for your home.

How Well Does Solar Panel Work on Cloudy Day?

Solar panels also work well on cloudy days, although they are less efficient at generating electricity than on sunny days. According to research, even on partly cloudy and cloudy days, solar cells can still produce 80% of their maximum output potential.

Homeowners in cloud covered areas realize that solar panels can still reduce their reliance on fossil fuel electricity and lower their electricity bills. They simply installed panels that met their overall energy goals, even if the numbers were higher due to regular cloud cover reducing efficiency.

What Happens When Solar Panel Does not Produce Enough Electricity?

Clouds are inevitable, so when you install solar panels, you need to be prepared for the local climate. Don't worry about poor performance after the panels are installed, you should focus on buying a solar system that meets your electricity needs.

Obviously, you want your solar panels to get as much sunlight as possible. Solar panels work best in bright, cloudless, sunny weather. It would also help if they were angled to receive as much sunlight as possible during peak hours.

Thus, you should get a solar panel design that accounts for factors such as:

  • Geography
  • Local weather
  • Peak sun hours
  • Roof shape and orientation
  • Current electricity use
  • Future electricity needs
  • Battery storage goals
  • Net metering goals

That said, if your solar panels don't generate enough power on a cloudy day, your home can still draw power from the grid to keep lights and appliances running. Your ultimate goal should be to install just the right amount of solar panels to ensure you get all the power you need during the day, regardless of cloud cover. Despite persistent myths about solar panels, they can still generate electricity on cloudy days. Solar panels work better on sunny days, but the possibility of cloud cover shouldn't scare you into getting your home on solar power.
