In the absence of a solar battery, a solar energy system operates by harnessing sunlight to generate direct current (DC) electricity through solar panels. This DC electricity is subsequently directed to an inverter, where it undergoes conversion into alternating current (AC), which is compatible with household electrical systems.
Initially, the generated electricity fulfills the energy demands of the home. Given that typical household consumption may not fully utilize the solar-generated electricity during daylight hours, any surplus energy is seamlessly exported to the grid. In return, the electricity retailer compensates the homeowner with credits for each kilowatt hour of exported electricity.
In scenarios where a solar system is integrated with a battery, the solar panels primarily power the household, with any excess energy not immediately consumed being directed to charge the battery storage system. Once the battery reaches full capacity, any surplus electricity is redirected to the grid.
During periods when the solar panels are not producing electricity, such as nighttime, and household demand exceeds solar generation, the stored energy in the battery is discharged to meet the home's electricity needs.
This combined solar and battery system optimizes energy utilization, ensuring efficient consumption and storage of renewable energy resources while providing reliable electricity supply to the household.
