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.

When is a solar system considered an onsite system?

When a solar system is installed directly on the purchaser’s property, and the renewable energy that it produces is consumed there, it’s considered an onsite system.

Should you invest in onsite solar?

Onsite solar is easily installed on rooftops or as ground-mounted panels on business property. Investing in solar installations creates a tangible asset for businesses to showcase their progressive sustainability strategy to stakeholders, customers, and the energy market. However, investing in onsite solar isn’t just a vanity project.

Is offsite solar better than onsite solar?

Regardless of the exact method, participating in offsite solar can have upsides similar to onsite. While both offsite and onsite options offer project structuring with no upfront installation costs and provide renewable energy at a fixed cost, the two system types ultimately can offer their own distinct benefits.
