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.

What is on-site power technology?

Forget about long-distance transmission lines with their energy losses, power surcharges, and other miscellaneous fees. This approach focuses on generating power close to the point of consumption, which is not only more efficient, but also more environmentally friendly. A Closer Look at On-Site Power Technology

What is on-site energy & how does it work?

On-site generation reduces these risks by producing energy directly at the facility, lowering transmission losses and offering the flexibility to operate in tandem with or independently from the grid. What’s Driving The Shift To On-Site Energy? There are several factors contributing to the widespread adoption of distributed generation, including:

What are the top energy technologies for on-site generation?

The top energy technologies leading the way when it comes to on-site generation include: Rooftop solar remains one of the most accessible and cost-effective ways to generate on-site power, particularly for facilities with high daytime energy usage.
