Can surplus solar energy be used in off-grid systems?

The research aims to evaluate the quantity of surplus solar energy generated in off-grid systems. One objective is to identify the patterns of surplus generation to see if this surplus could be easily put to use. To achieve the aim, the researchers analysed various load consumption data for households with solar generation.

How much solar energy is surplus?

The use of hourly data for these households did not cause a significant error in determining the solar surplus. From this analysis, it is estimated that, on average, 50% of the solar energy is surplus. In most homes, the primary loads are connected in the evening, and the next day the battery is recharged from the solar module.

How to evaluate surplus solar power?

For evaluating the surplus energy, the solar output is compared with 5-minute and hourly resolution solar power from the Solcast software for 5th Jan, and 6th Jan. Solcast provides solar irradiance values which were scaled according to the rating of the solar panel installed at the SHS to determine the potential solar generation.

How does surplus electricity affect a stand-alone HREs?

While it can be transferred to the grid utility in grid-connected HRESs, off-grid systems face a significant challenge with high amounts of excess power. Therefore, surplus electricity is a crucial factor that affects the development of stand-alone HRESs.

Can off-grid solar systems be controlled with energy storage?

Many papers cover the control of grid-connected solar systems with energy storage, but few publications cover the control of off-grid SHS. Researchers from Pakistan propose connecting SHS together with energy storage to enable surplus power to be delivered to community loads .

How much excess energy is in a grid-connected HREs?

According to Figaj's simulation , the monthly excess energy in a grid-connected HRES oscillates between nearly 0 and 5.5%, and would be less than 3% on an annual basis. The less than 3% excess electricity in grid-connected HRESs is also shown in the results of [, , , , ], and .
