Solar-Powered Microgrids

Detailed overview of innovation with sample startups and prominent university research

What it is

A solar-powered microgrid is a small-scale, localized energy system that integrates solar PV as the primary energy source. Microgrids can operate independently from the main grid, providing energy resilience and security to local communities or facilities.

Impact on climate action

Solar-Powered Microgrids under Distributed Solar PV enhance climate action by providing resilient, decentralized energy solutions. By integrating solar power with local energy distribution networks, these microgrids reduce reliance on centralized fossil fuel-based grids, mitigate carbon emissions, and promote energy independence, fostering a more sustainable and resilient energy infrastructure.

Underlying
Technology

  • Solar PV Panels: Solar panels convert sunlight into electricity, providing the primary energy source for the microgrid.
  • Energy Storage Systems (ESS): ESS, such as batteries, store excess solar energy for later use, ensuring a reliable and consistent power supply even when the sun isn’t shining.
  • Microgrid Controllers: Microgrid controllers manage and optimize energy flows within the microgrid, balancing energy production with consumption and storage.
  • Grid Integration: Solar microgrids can be grid-tied or off-grid. Grid-tied microgrids can draw power from the main grid when needed, while off-grid microgrids operate independently.
  • Distributed Energy Resources (DERs): In addition to solar PV, microgrids can integrate other DERs, such as wind turbines, generators, and electric vehicle charging stations.
