There’s no question that battery-based energy storage systems (ESS) can add an exciting level of cost-effectiveness and flexibility to photovoltaic (PV) systems. There are many reasons: a growing number of utilities have modified the incentives consumers receive for exporting solar system electricity back to the grid by introducing time-of-use and demand charges or shifting rate structures to assign the highest rates to evening periods. Now more than ever, the ability to self-store solar-generated power is crucial to energy independence for utility customers who want to unlock some serious power cost savings.
At Adara, we’ve been asked many times, “What are the key factors when pairing an ESS system to my solar system?” Here’s a quick checklist that can help you make a savvy choice.
