Getting Through The Winter With Solar Panels

You may be wondering how solar panels can function in an area that has long, harsh winters. After all, this is a technology that relies on the sun in order to function.

But the past 10 years have brought a lot of innovation and progress to solar panel technology. Now this technology has progressed to the point that solar panels can easily produce electricity even during inclement weather conditions.

If you have an off grid system that works independently of a energy utility system, your solar energy system should include a set of storage batteries. These batteries are similar to the kind used in autos. They are designed to hold any excess energy that your solar panels generate during the daylight hours. If the battery storage system is correctly designed for your region, it will include enough of these batteries to store electricity for the number of cloudy days that are normal for where you live.  

If your system is tied to the grid (connected to the local electric company) it won’t require storage batteries. After the sun goes down or if there is a prolonged period of inclement weather obscuring the sun, your system will automatically use electricity from the local power company. Of course, on sunny days, your solar panels will be generating your electricity, so you will still be reaping the benefits of lower electric bills.

In some places, you may even be able to sell power back to your local electric company. This is yet another way solar panels can prove cost effective. The way this works is that excess power produces by your solar panels flows back into the grid and you are credited for it on your bill.  So even when you have to use electricity from the grid at night or on overcast days, the excess that was generated by your solar panels will still be used to lower your overall utility costs.
