Find out if your local energy provider offers meter rollback programs. Once you have a solar energy system, you should consider joining one of these programs so you can sell the energy you produce to the main grid and draw the same amount of energy instead of purchasing an expensive battery system to store your power.
Keep in mind that purchasing a solar power system often enables you to receive tax credits from the government. You may find that you get back as much as 30 percent of the total cost of your system. So, if you look into a system and think that it costs too much, investigate whether or not you will get credit back to determine how affordable it actually is.
