How Does Someone Get Energy From A Solar Panel At Night?

There are many people who believe that installing solar panels on the roof is not

cost effective since the photovoltaic cells only generate electricity during the day. These people wonder why they should go through the hassle of building a solar panel array that only generates electricity when the sun is shining.

This misunderstanding is commonplace, especially since obtaining electricity from the sun is a complicated process. Basically what happens is the sun strikes the photovoltaic cells, thus generating electricity. This is well known and understood. However, what some people do not know is that the electricity that is NOT being used in then stored in batteries. The household appliances draw electricity from the sun, and when that is not enough, then they draw from the batteries.

The batteries last between three and ten years, so there should not be a problem there. They come in different sizes and varieties and aren't terribly hard to find. Since they are a vital component of the solar panel installation, feel free to shop around and compare prices. The are large like car batteries and should not be drawn at more than 80 percent of their capacity for long periods of time. Also, there may be some people who are worried about drawing too much electricity from the batteries and having them overload. Fortunately there is a solution for that as well, and it is called a charge controller. Unlike fuse panels and fuses that trip when overworked, solar panel arrays contain a device that regulates how much electricity is stored at one time within the batteries. The charge converter basically prevents a overload of the batteries and stops charging them when it senses that the batteries are completely full.

The photvoltaic cells, the batteries, the charge controller and other components of the solar panel all work together to generate electricity for homes all across the country. Even in places where power plants may be far away or ones that don't offer many options, there is another choice. If the reader decides he wants to build a do-it-yourself (DIY) solar panel, then he needs to know it will take time. However, it is a realistic way to consistently generate electricity even at night time or in cloudy weather. Now that the question of what to do when the sun sets has been answered, feel free to share this information with anyone who asks.

Clearly this article was not about the actual construction of the solar panel array, but important information to know before one starts. Since the reader is most likely curious about the actual building of one (otherwise he or she probably wouldn't have read this to begin with), he will not be left empty-handed.
