In recent years, the cost of lithium-ion batteries has also been dropping down significantly for electric vehicles as well as energy storage. Renewable energy, such as wind and solar, combined with better energy storage technologies and more efficient electric grids, is the biggest hope for the world to reduce “green-house” gas emissions and achieve desirable climate targets.

We can all observe a global trend of distributed, decentralized microgrids powered primarily by PV solar coupled with Battery Energy Storage Systems (BESS).

A microgrid can be a industrial facility, university campus, hospital, public building, commercial property, housing community, mining site, etc.. The sizes of such microgrid PV solar and BESS projects are often too small and therefore neglected by large energy companies, but too big for small companies that are lack of technical and financial capabilities, especially for those projects that are financed through an energy purchase and sale agreement.
