A three kW solar PV installation could pay for itself in about 12 years, leaving about eight years of “above-cost” payments, for a very reasonable rate of return over the 20-year term of the contract. For a more accurate estimate of the payback period, we recommend using the RETScreen tool: www.retscreen.net.
