What is a Solar Energy System

What is a Photovoltaic PV Solar Energy System? pv system consists of one or more solar panels combined with other electrical and mechanical equipment, an inverter that uses energy from the sun to generate electricity. PV systems can vary greatly in size, from small rooftop or portable systems to large utility-scale production facilities.

PV systems are a renewable energy technology that converts energy from the sun into electricity using photovoltaics. These photovoltaics, also known as solar panels, provide a reliable green energy solution.

What is Photovoltaic PV Solar Energy System? photovoltaic solar energy is generated by converting sunlight into electricity using a technology based on the photoelectric effect. It is a renewable, inexhaustible and non-polluting type of energy that can be produced in plants ranging from small generators for self-consumption to large photovoltaic power plants.

In solar power plants, it is a sustainable, low-maintenance option for anyone who wants to contribute to a greener environment, as the system does not cause any pollution or emissions and has numerous advantages.

Photovoltaic systems use photovoltaic cells to collect solar energy from sunlight and convert it into direct current (DC) electricity. The reflection of sunlight creates an electric field in photovoltaic systems, causing electricity to flow. The DC electricity will be transported to an inverter that will convert this DC power into alternating current (AC). This AC power is the type of electricity used for electrical appliances in your home, also called AC load.

Advantages of Photovoltaic Energy

  • It is a type of energy that is 100% renewable, inexhaustible and non-polluting, consumes no fuel, generates no waste and therefore contributes to sustainable development.
  • It is modular and can be used in installations ranging from huge solar installations on the ground to small rooftop panels.
  • It can store excess electricity that can be used later.
  • It is particularly suitable for rural or isolated geographical areas where there are no power lines, where it is difficult or expensive to install, and where there are hours of sunlight.
  • It contributes to creating green jobs and stimulating the national economy with cutting-edge projects.

How is PV Power Generated?

Photovoltaic energy is created in the following steps:

  • The semiconductor absorbs light and transfers this energy to negatively charged particles called electrons.
  • The electrons flow through the semiconductor as electric current, while other cell layers receive the current from the semiconductor.
  • The current flows through metal contacts before going to an inverter.
  • The inverter converts direct current (DC) into alternating current (AC).
  • The AC goes into the electricity grid or is connected to the building’s circuit, depending on the system.

Solar Power Plants are Environmentally Friendly

Solar energy has far fewer carbon emissions than standard forms of non-green energy that rely heavily on fossil fuels. Greenhouse gas emissions are negligible because solar energy does not burn fuel. Every kilowatt-hour (kWh) of solar energy significantly reduces greenhouse gas emissions such as CO2 and other dangerous pollutants such as sulfur oxides, nitrogen oxides and particulate matter. The more people choose renewable energy, the cleaner our air will be.

Energy Storage

If you don’t use your solar energy immediately, it will need to be stored in batteries, which are both costly and take up space. These batteries charge during the day so you have energy to use at night.

Solar Energy Renewable Energy Source

Solar energy is a clean, cheap and renewable energy source. It can be used almost anywhere in the world. Any point where sunlight hits the earth’s surface is a potential location for generating solar energy.

Because solar energy comes from the sun, it represents an unlimited source of power. Renewable energy technologies generate electricity from infinite resources. For example, let’s compare generating electricity from renewable sources with fossil fuels. Oil, gas and coal take hundreds of thousands of years to form, and every time one of these resources is burned to generate electricity, the finite resource is exhausted.

What Does a Solar Inverter Do?

A solar inverter takes DC electricity from the solar array and uses it to create AC electricity. Inverters are like the brain of the system. In addition to converting DC to AC power, they also provide ground fault protection and system statistics, including voltage and current in the AC and DC circuits, energy production and maximum power point tracking.

Centralized inverters have dominated the solar industry from the beginning. The introduction of microinverters is one of the biggest technology shifts in the PV industry. Microinverters optimize for each individual solar panel, not for the entire solar system as central inverters do. This ensures that each solar panel performs at its maximum potential.

Inverters are important for almost all solar energy systems and are generally the most expensive component after solar panels.
