Frequently Asked Questions

What happens if there is snow on solar panels?

Solar panels are used to generate power from sunlight. So, if there is snow on panels then the solar panels will not properly catch the sunlight. The snow is not that heavy to cause any structural disorder with your panels but they are enough to block the radiation causing stoppage of solar production. If there is snow on panels, make sure to clean it at that time to avoid any power storage problems.

Will I still receive an electric bill if I have solar panels?

You can receive an electricity bill if your solar system has battery storage plus it is not totally off the grid. Like, if you have connected power supply to your house, even if you don’t consume any, still you might be surprised with a teensy charge. Thus, you can reduce your electricity bill or can totally get rid of it, if you own a solar panel system which matches the same energy use of your house.
