In one of our previous blog posts, we covered what a grid connected solar system is and how it can benefit your home. Now it is time to consider an "off the grid" solar system and why it may be the system for you.
Firstly, what is an off the grid solar system? An off the grid solar system is a system that is designed to work on it's own. It is not connected to the mains power supply or any other power grid. It solely relies on the solar panels, wind turbines or micro hydro system to produce the power which then stored in batteries. Like every system, it has it's advantages and disadvantages.
Advantages of an off the grid system are that you are completely energy independent, meaning that you don't get the negatives that come with using the main utility grid, such as power outages. An off the grid system can be installed virtually anywhere, as long as there is sun. It stores the electricity provided so you will always have electricity to use provided that there is enough stored. You will not be recieving any power bills at all with an off the grid system because it is independent, making it a free power solution for your home.
There are some disadvantages with this system however. Because you are power independent, if your system doesn't produce enough power, you don't have other option. This is rarely a problem however, and if the system has been designed properly, you should not experience this problem. An off the grid system can cost a bit more than a grid tied system too. Another disadvantage is that an off the grid system produces less power than an equal grid tied system of the same size in the same situation. This is due to the way the system and batteries work. And when you have filled the batteries, all the power that is being produced has no where to go, so it is essentially wasted.
