Technical FAQs 4

What is on-site solar?

On-site solar refers to a solar energy system that is installed directly on the property where the energy will be used. This is the most common form of solar energy generation for residential homes and commercial buildings.

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?

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.

What is an offsite Solar System?

An offsite solar system is not located on the purchaser’s property but still allows the purchaser to benefit from the renewable energy it produces in the form of credits that are used to offset their facility’s energy costs.
