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.
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.
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.
Based on literature, exceeding 10% of the energy surplus level indicates suboptimal energy efficiency in the renewable system. Surplus electricity is not a problem in some parts of the world, such as Europe, where most regions have access to the synchronous electrical grid.
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.
Unused generated solar power can be stored in energy storage systems, such as batteries, for later use when solar production is low. Alternatively, it can be exported back to the electrical grid, where it is distributed to other consumers. In some cases, if there are no storage or export options, the excess electricity may be curtailed or wasted.

Why Is My Electric Bill So High With Solar Panels?
The best option is pairing the solar system with a battery. You can use a battery to store the surplus energy from the solar system rather than feeding it back into the electric grid, and then use that stored power in the evening rather than drawing in from the grid. So, let''s say you produce 10 kWh of excess solar power during the day ...

Solar Power and the Electric Grid
Generation technologies do not simply provide kilowatt hours to the grid. In varying degrees, they also provide ramping ability to follow load, stay ready to meet demand peaks (dispatchability), and adjust their operating condi-tions to maintain grid stability. Power plants meeting base-load must run 24/7 with low operating costs.

Excess electricity problem in off-grid hybrid renewable energy …
When the HRES is integrated with the utility grid, the generated surplus power after charging the storage units can be injected into the grid, which leads to near-zero excess electricity [4]. In these systems, purchasing electricity from the grid can lead to peak-shaving, which causes less surplus electricity generation from the HRES.
