This document discusses how solar renewable energy credits (SRECs) can maximize the return on investment of solar energy projects. SRECs are tradable commodities that provide a source of income for solar project owners in states with renewable portfolio standards that include solar carve-outs. The value of SRECs is driven by supply from residential and commercial solar systems and demand from energy suppliers needing SRECs to meet their state's renewable standards. Being able to reliably monetize SRECs through long-term financing is essential for solar project finance.
