Residential distributed photovoltaic grid-connected power generation systems refer to systems located near the user, typically installed on the user's roof, and are particularly suitable for villa roofs. The generated electricity is utilized locally and connected to the power grid at a voltage level of 220V/380V.
Household distributed photovoltaic power generation systems are a new type of power generation and comprehensive energy utilization method with broad development prospects. They advocate the principle of "generating power nearby, connecting to the grid nearby, converting power nearby, and using power nearby". They can not only effectively increase the power generation of photovoltaic power plants of the same scale, but also effectively solve the problems of voltage boosting and power loss.
What components make up a residential distributed photovoltaic (PV) power generation system?
A residential distributed photovoltaic power generation system consists of a photovoltaic array (composed of photovoltaic modules connected in series and parallel), a photovoltaic inverter, a photovoltaic support structure, a photovoltaic grid-connected box, a controller (optional), a battery bank (optional), and AC/DC cables.
The core component of a photovoltaic power generation system is the photovoltaic module, which is made up of photovoltaic cells connected in series and parallel and packaged together. It directly converts the sun's light energy into electrical energy.
The electricity generated by photovoltaic modules is direct current (DC), which can be converted into alternating current (AC) by an inverter for use, or it can all be fed into the public power grid. From another perspective, the electricity generated by photovoltaic power generation systems can be used immediately after generation, or it can be stored in energy storage devices such as batteries and released for use as needed.
