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.

Is on-site solar a good choice?

While not a de facto choice – especially for large hyperscale facilities – on-site solar is growing in popularity as companies look to boost their green credentials and save money against high energy costs. Operators large and small have deployed solar panels to the rooftops of their facilities.

What is solar energy used for?

Solar technologies can harness this energy for a variety of uses, including generating electricity, providing light or a comfortable interior environment, and heating water for domestic, commercial, or industrial use. There are three main ways to harness solar energy: photovoltaics, solar heating & cooling, and concentrating solar power.

Is rooftop solar a good option for a building?

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. These systems can typically offset a large portion of energy consumption in a building and are relatively simple to install.
