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.
If you own your own business, consider installing solar panels to your building. This will help cut your overhead expenses. Solar energy can power your computers, lighting and other office equipment. Additionally, business owners can get tax breaks for installing energy saving green products such as solar panels and solar hot water heaters.

Be realistic about the costs of having a solar energy system. If you're paying much less than other systems that are around the same size as yours, you may have poor equipment or installation work. Like with many things in life you get what you pay for. Quality installation work and equipment isn't going to be cheap. You may have substantial savings by going with a large company, but other companies may be cutting corners to keep costs down.
