In many areas where the electricity supply is not reliable, most homes depend on alternative sources of energy. One of the most popular sources today is solar energy, which is a better source because it is renewable.
Solar PV is a clean, renewable energy source. It converts the radiation from the sun into electricity. PV stands for photovoltaic, representing the cells that absorb the sunlight. The cells use the sunlight to generate an electrical current. The current all the PV cells generate will combine to produce enough electricity to power your home.
The solar PV panel system
A solar PV panel is a complete system. It incorporates solar panels to generate and convert solar energy into electricity, which you can use at home to power your household appliances and other equipment. The system design varies according to the need and your location. If you live around Cheshire, you can get in touch with a specialist in installing solar panels in Cheshire during office hours.
Typically, you connect your solar PV panel system to a grid. This means that if your solar panels do not work at night, you can still have electricity that will come from the grid. Conversely, the excess electricity from your system goes to the grid.
But if you do not want to connect to the grid, your option is to have a stand-alone system. With this type of PV solar panel system, you need to add solar batteries to your system so you can have electricity in the evening. This is a more convenient method if you are living in a remote area.
How does the system work?
Solar PV panels comprise small interconnected photovoltaic cells. They make these cells from various semiconducting materials, such as silicon, copper indium gallium diselenide, and cadmium telluride. Among the three, silicon is the most commonly used because it is the most abundant semiconductor.
Each unit of PV cell is small, and the manufacturer combines them to form a solar panel. When the sun shines over them, the process creates an electric field. If the sun is stronger, your solar PV system will produce more electric energy. There will be a significant reduction in electricity production when the day is cloudy. But the PV cells can still harness energy from indirect sunlight and reflected light.
If your electricity consumption is minimal during the day, the stand-alone system stores the extra electricity in the rechargeable home battery so you can have enough power in the evening.
The electricity the solar cells produce is direct current (DC). The system needs an inverter to convert direct current into alternating current (AC), which is the type of electricity that powers the home.
Solar PV panels are durable and require minimal maintenance. They can last for 25 to 30 years although some essential parts, like the inverter, might need replacement. Check with your installer about the efficient methods to maintain the system, just to be safe.
