Cost of Solar Panel in Lagos Nigeria

Solar panels are the major component of a solar power system. It converts light energy from the sun to direct current DC electric voltage. For the latest cost of solar panels in Nigeria click here

Solar panels are made up of arrays of photovoltaic cells (also called solar cells), connected in series and parallel to deliver rated voltage and power.

The photovoltaic cell is the basic component of a solar panel. PV cells are made from semiconductor materials, like silicon and doped with other elements, like Boron and phosphorus.

These elements create an N-type layer and a P-type layer on the cell. The junctions between the N-type layer and P-type layer contains an electric field, which stops electrons from moving across the junction, effectively creating an open circuit.

When a photovoltaic cell is exposed to sunlight, energy-carrying particles in light called photons continuously strike the p-n junction area of the cell and are absorbed.

Energy derived from these absorbed photons provides electrons on the cell with enough energy to overcome the potential barrier of the electric field in the p-n junction. This causes electrons to flow across the junction to power electrical appliances.

A solar panel consists of an array of solar cells, usually covered in glass. Solar panels provide power for charging your batteries and for powering your appliances.

Solar panels are expensive per watt (though they are getting cheaper) when compared to a petrol generator, but uses free energy from the sun.

For example, an 100 watt solar panel can cost between about 25,000 and 50,000 Naira in Nigeria. Solar panels may also come in different power capacities.

Solar panels can last for up to 30 years.

One or more solar panels will be required in a solar power system. A two bedroom flat, for example could require three to 10 solar panels.
