Solar power is a beautiful renewable resource, as well as hydro and wind power! So many Americans really want to become more independent, more self sustainable but really believe the myths that the cant afford to either go off the grid or even do a grid tied solar setup! Really? Dont believe the naysayers! Renewable energy sources have come down in price. And with federal incentives and state rebates, it PAYS to invest in something that gives you FREEDOM, independence, and a source of power that NO ONE can shut off!! Think about that? We buy ourselves NEw trucks and cars but wont invest in life insurance policy of free renewable electricity to FREE US? Thats incredible. So today I am debunking those myths! YOU CAN save money with solar, you can free yourself! Smarten up people, these things aren’t for the rich!
