Most locations across Guyana have excellent solar insolation levels and are ideal for solar PV generation. As of 2018, the total installed capacity for Solar PV in Guyana is 4.63 MW, with an estimated annual generation of 7.16 GWh.
In Guyana, 1.184 MW of solar PV systems will be installed at 80 public buildings in all 10 Administrative Regions in 2019.
GEA supported the implementation of a massive electrification project to supply, deliver and distribute 30,000 Solar Home Energy Systems to Hinterland and riverine communities in Guyana. A total of 26,398 units were distributed as of December 2023.
In Guyana, solar energy is used for several purposes, such as drying agricultural produce and irrigation, ICT, and to improve electricity access in rural areas. Under the Hinterland Electrification Programme, over 19,000 solar PV systems had been installed in nearly 200 communities by 2018.
Guyana Power and Light Inc. (GPL) is preparing plans for three utility-scale solar PV farms totaling 30 MW for the national grid in the long term, as well as a 0.75 MW Solar PV Farm at Wakenaam and a 4 MW Solar PV Farm at Onverwagt in the near future.
Government of Guyana commissioned its second mega-scale solar farm, the 1.5 MW utility-scale solar PV plant at Bartica, Region Seven (Cuyuni-Mazaruni) in March 2023. At twenty-two (22) off-grid locations, GEA installed over 163 kWp of solar PV capacity and 800 kWh of battery energy storage.
