Scientists call them photovoltaic cells. Which is quite a mouthful. So, let’s call them solar panels instead.
What do they do? They convert light into electricity. It doesn’t matter if the sun is shining or not. As long as there’s light, your solar panels are hard at work.
Once that light becomes energy, can you use it? Sure, as long as you’re powering something that runs with direct current (DC). Since most of us run our homes and businesses with alternating current (AC), solar systems come with an inverter to convert the current from DC to AC.
Solar panels don’t have moving parts that can break down. They don’t create hazardous byproducts that pollute the environment. And you can put them just about anywhere. On your home. On your business. In your yard. Or on your boat or RV.
