But there has been much innovation and progress in solar panel technology during the past 10 years. Now, even when it’s snowy, cloudy or rainy, solar panels can easily make electricity.

If you have an off grid system that works independently of a power utility company, your solar energy system will include a set of storage batteries. These batteries are like the ones used in cars. They are made to store any extra electricity that your solar panels generate during the day. Your back-up storage system should have enough of these batteries to store power in correspondence to the number of cloudy days normal for your geographical region.  

If your system is tied to the grid (connected to the local electric company) it won’t require storage batteries. When the sun goes down at night, or there’s a stretch of inclement weather obscuring the sun for days, your power system will automatically get electricity from your local energy company. You’ll still be reaping the benefit of lower electric costs because on sunny days your electricity will be generated by 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 energy even more cost effective. The way this is set up is that excess power generated by your solar panels flows back into the company and you received credit for it on your bill.  So even when you need to use electricity from the grid at night or on overcast days, the surplus that was produced by your solar panels can still be used to reduce your overall utility bill.
