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.
Check that your solar-energy installer has the proper licenses and insurance. Installing solar panels on a steep roof is a delicate job, and you should feel confident that your installers know what they are doing. At a minimum, look for a contracting license, workers compensation insurance, and general liability insurance.
You might be able to get your solar energy equipment installed for a huge discount or perhaps even free. The government is trying to promote solar energy benefits and many wish to cover apart or all of the costs in return for its installation.
