In some areas, the best incentive for investing in a residential solar power system may come from the local utility. On top of federal tax credits, improved resale value, and various state incentives, some consumers can benefit with additional credit from the local utility when they are able to sell back power they generate with a PV solar energy system. This arrangement not only saves them more money, it also accelerates system payback and return on investment.
But what happens if or when these incentives are limited or even ended? If a consumer has a simple grid-tied system, he doesn’t have many options if the utility won’t take the power back; he has to either use it or lose it. But if a grid-interactive system with energy storage is installed with a smarter inverter/charger at the heart of it, the consumer has a lot more control over his energy destiny with technology that can mitigate or offset the need to purchase utility power.
