4 Frequently Asked Questions about "Solar spherical on-site energy storage system"

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 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.

Could concrete spheres be a sea-based alternative to land-hungry energy storage?

That's exactly what researchers at Germany's Fraunhofer Institute are exploring, with plans underway to submerge massive concrete spheres in the ocean, offering a sea-based alternative to land-hungry energy storage solutions.

What is thermal energy storage (TES)?

In Figure 5, the addition of thermal energy storage (TES) allows the facility to use the on-site solar PV to charge both the TES and BES instead of exporting to the grid or curtailing the excess generation. Also, the addition of TES further reduces peak demand from 70 kW to less than 50 kW.
