The Solar Market is confusing. Never respond to heavy sales pitches, including ONLINE meetings. Instead get real factual information from companies and use your own intelligence to sort things out. There are permits/contracts to be obtained from the grid company as well as local permits to allow such installations. The solar company should also help with filling out the tax rebate forms, presently 30% of material cost, plus an incentive to be filed with the electrical grid company for your residential area.
