An on-grid solar system is an electrical generator using solar energy, a non-conventional source of energy. In contrast with off-grid systems, grid-tied systems are connected to the grid. As a consequence, the not used generated power of the system can be sold to the electrical company. In addition, the user can buy energy from the grid if needed.

Customer ServiceOften referred to as a grid-tie or grid-connected system, an on-grid solar system is a system that is connected to the utility grid. It allows your home to use the power generated by your solar panels, as well as the power supplied by the grid. This means even on cloudy days or at night, you will always have a reliable power source.

Customer ServiceWhat Happens to Excess Solar Power off Grid? When you have a solar system installed on your home, there are a few different ways to use the excess power that it produces. One way is to simply sell it back to the utility company through what''s called net metering. With this option, you essentially have a two-way meter installed at your home.
Customer ServiceThe 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.
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.
By contributing to the grid, solar power systems participate in a process known as grid feedback, where renewable energy sources like solar help offset non-renewable energy use. Properly sized solar power systems are designed to minimize the amount of excess electricity fed back into the grid, ensuring efficient energy distribution.
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.
