PV - Solar Panel - Photovoltaic Systems

How does solar pv work diagram

How Does Solar PV Work?

A solar photovoltaic (PV) panel is made up of several silicon cell wafers, connected to each other in series. When a photon of light from the sun makes contact with the silicon cell a photovoltaic effect occurs, generating electricity. The most efficient solar panels can convert more than 20% of sunlight into electricity.


The renewable energy generated by PV solar panels is in DC 'direct current', whereas, the "mains" electricity we all use is AC - 'alternating current'. In order to utilise the electricity from the panels it must be converted from DC to AC. An additional device called an Inverter undertakes this role along with constantly monitoring the electricity coming in from the national grid, and then modifying the DC electricity generated by the solar panels to match it perfectly.


The electricity generated by the solar PV system is automatically used to supply a property with any excess being automatically sold straight back to the supplier or used to charge a Solar PV Battery. 


Any shortfall of power, such as peak use times or at night, is topped up by the supplier or discharged from the solar battery storage system.


Solar PV operates on light intensity, not heat, so even if the day seems cold, if there is light, the system will be generating electricity, PV systems will therefore generate electricity all year round.

Cost and Benefits

Over the course of a year, a solar photovoltaic system will save you money by reducing your electricity bill, and will earn you an income for every unit of electricity that you generate. 


Excess electricity is exported back to the grid earning an "Export" payment. This is calculated by your energy provider through the home smart electricity meter. This payment is lower than the import electricity cost, it is therefore more advantageous to use as much of the free electricity as possible. This is where smart energy products and solar battery storage can make a difference to payback times.
