Keep your solar panels out of the shade. It might seem obvious, but your solar panels do need sun. Make sure that you are not installing them in the shade. Trim back the branches on surrounding trees if you need to. Failing to do so could cost you more than half your energy output.
Remember to account for any extra influences when you calculate how much you can expect your solar panels to output. There are some intended outputs specified on panels, but that is only accurate if they are placed in an area that is sunny all the time. Any obstruction from trees or from a cloudy day will decrease the output.

Since children are the ones who will be running the future it is important to teach them early about renewable energy. As a parent you can set the example by using solar energy whenever possible. If it is not possible to swap your entire house over, maybe switch out your outdoor lighting.
