[A Complete Guide] A grid-connected photovoltaic (PV) system, also known as a grid-tied or on-grid solar system, is a renewable energy system that generates electricity using solar panels. The generated electricity is used to power homes and businesses, and any excess energy can be fed back into the electrical grid.
Solar powered PV systems can sometimes produce more electricity than is actually needed or consumed, especially during the long hot summer months. This extra or surplus electricity is either stored in batteries or as in most grid connected PV systems, fed directly back into the electrical grid network.
With the advance in technology and the increase in the market, the cost of solar PV modules is decreasing whereas the cost of batteries is becoming a significant part of a standalone system. Non-optimal use of batteries can result in the reduced life of such a significant device in the system.
The photovoltaic battery (PVB) system is studied from different aspects such as demand-side management (DSM), system flexible operation, system life cycle analysis, various agent study, and grid impact, under the growing scale and complexity.
