Technical FAQs 4

How can on-site solar PV & energy storage improve sustainability?

To achieve sustainability goals while meeting the increasing electricity demands of electrification, organizations are pairing on-site solar PV generation with on-site energy storage. These systems, which are considered as “behind-the-meter” (BTM) systems, allow facilities to maximize the benefits of on-site renewable generation.

What is energy storage?

Energy storage is a system that can help more effectively integrate solar into the energy landscape. Sometimes it is co-located with, or placed next to, a solar energy system, and sometimes the storage system stands alone.

Why is solar storage important?

Solar storage is important because it allows solar energy to contribute to the electricity supply even when the sun isn’t shining. It also helps smooth out variations in solar energy flow on the grid, which are caused by changes in sunlight.

Who can benefit from solar-plus-storage systems?

Residential and commercial solar customers, utilities, and large-scale solar operators can all benefit from solar-plus-storage systems. As research continues and costs decrease, solar and storage solutions will become more accessible to all Americans.
