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.
In recent years smaller solar systems have become available that the average person can use at a relatively low cost. They might not be able to power your home, but they can power many of your smaller electronics and help you reduce the amount of energy you consume. Search for some smaller systems to help reduces your carbon footprint.
One major advantage of solar power is that there are a wide range of systems on the market. While there are those that are very expensive, others are quite affordable. Therefore, regardless of your income level, you can afford to set up a solar power system. You just need to do your research and figure out what product is best for you.
