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.
When using solar power, you do not have to worry about harming the environment in any way. Fossil fuels send harmful greenhouse gases off into the atmosphere, and they contribute to global warming and climate change. However, solar cells have no impact on the environment and are safe to use.
