The best payback and return on investment for solar is to pay up front, out of pocket.
Another good option available to Colorado homeowners is the RENU loan program established by Colorado Energy Office. The RENU loan program is designed to provide low-interest financing for energy efficiency upgrades, including solar PV. Installation projects must be completed by an authorized RENU contractor. Visit the RENU website for a list of authorized contractors.
Some areas and installers offer solar leases and power purchase agreements (PPA) – through which a company pays for the cost of the system in exchange for the opportunity to take advantage of the tax benefits. The homeowner or business owner then makes monthly payments to the lease or PPA holder for the use of the solar equipment or the kilowatt-hours generated.
