Do your best to reduce your energy consumption before investing in solar energy. Your solar energy system will be more affordable if you can live with a reasonable quantity of energy. Start by improving your insulation, make an effort to turn off appliances and replace old appliances with energy-efficient ones.
Be prepared to keep your solar panels clean. The dirtier they get, the less efficient they are at generating power. While it is true that rain and wind can often take care of a lot of this for you, you do need to get up there sometimes and dust them off yourself.

When looking for a solar panel system, try to find discounts. So while theses initial costs are intimidating, know that there is help available. Verify whether state or federal rebates and grants are available to assist you. This reduces the costs greatly. You can even get some deductions at tax time.
If you decide to put solar energy panels on your home, remember to keep them clean. Your solar panels must reflect the sun's rays in order to store the sun's energy for use in your home or business. If they are dirty, they can not effectively do this. By keeping them clean, you will get the most bang for your buck!
