4 FAQs about No-grid solar on-site energy storage

Can on-site storage be used alongside solar PV?

If a utility restricts the exports from a facility to the grid, the use of on-site storage alongside solar PV can provide a solution to avoid costly infrastructure upgrades, thus increasing the feasibility of larger on-site PV installations.

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.

Can solar PV & electrical storage be combined?

Ultimately, the ideal combination of thermal and electrical storage will be dependent on the utility restrictions and the end uses at the facility. Finally, the use of on-site solar PV and a larger storage system can complement each other to largely eliminate the need for grid supplied electricity.

How can a large solar PV array reduce grid exports?

Graph showing the production from an even larger on-site solar PV array, the charge/discharge of both a BES and a larger TES system, and their effect on the net load. To further reduce the grid exports, the facility would need to curtail a fraction of the total on-site generation.
