Technical FAQs 4

What are onsite solar installations?

Onsite solar installations are renewable energy systems deployed directly on your business premises. These systems offer immediate and visible benefits while giving you direct control over your energy generation.

Should businesses choose onsite or offsite solar?

As businesses work toward reducing their carbon footprints and energy costs, they face a pivotal decision: should they opt for an onsite renewable energy solution, like a rooftop solar installation, or consider an offsite option, such as grid-connected Open Access solar?

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.

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.
