If you live in an area that experiences long, harsh winters you may want to know if solar panels would work on your home. After all, this is a technology that relies on the sun in order to work efficiently.
But the past 10 years have brought much innovation and progress to solar panel technology. Now this technology has progressed to the point that solar panels can easily create electricity even on cloudy, snowy or rainy days.

If yours is an off grid system that works separately of a energy utility system, your solar power system should include a set of back-up batteries. These batteries are like the ones used in cars. They are designed to store any excess power that your solar panels make during the sunny part of the day. If your battery storage system is properly designed for your region, it will include the right number of these batteries to store electricity for the number of overcast days that are usual for where you live.
If you have a system that is connected to the grid of your local electric utility company, then you won’t require support batteries. When the sun disappears at night, or there’s a spell of inclement weather where you don’t see the sun for days, your power system will automatically get electricity from your local energy company. You’ll still be getting the benefit of lower power bills because on sunny days your electricity will be coming from your own solar panels.

In some areas, you may even be able to sell electricity back to your local power company. This arrangement makes solar power even more cost effective. The way this is set up is that unused electricity generated by your solar panels goes back into the grid and you received credit for it on your account. That way, even if you need to use electricity from the grid at night or on overcast days, any unused power that your solar panels were able to generate will still be lowering your overall utility bills.
