Supply of solar photovoltaic power generation system

What is solar photovoltaic (PV) power generation?

Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels. Solar panels, also called PV panels, are combined into arrays in a PV system. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations.

What is a photovoltaic system?

Photovoltaic systems have long been used in specialized applications as stand-alone installations (island systems). Grid-connected PV systems were first constructed in the 1990s. Nowadays, solar energy for electricity generation is applied on the wide range between small roof-top PV systems and large utility scale solar parks.

What are the components of a solar PV system?

The basic components of these two configurations of PV systems include solar panels, combiner boxes, inverters, optimizers, and disconnects. Grid-connected PV systems also may include meters, batteries, charge controllers, and battery disconnects. There are several advantages and disadvantages to solar PV power generation (see Table 1).

What is a PV solar system?

A PV solar system typically includes a grid and combinations of PV panels, a load controller, a DC to AC inverter, a power meter, a circuit breaker, and, notably, an array of batteries, depending on system size. PV solar systems have shown promising results in a variety of applications, particularly those that are off the grid [24–26].

How does a photovoltaic system work?

A photovoltaic system is designed to generate and supply electricity from solar radiant energy using solar panel. Solar panels absorb the solar radiant energy and convert it into electricity. An inverter is also connected to convert DC power to AC.

What is solar power?

Solar power is the conversion of sunlight into electricity, either directly using photovoltaic (PV), or indirectly using concentrated solar power (CSP). The research has been underway since very beginning for the development of an affordable, in-exhaustive and clean solar energy technology for longer term benefits.
