Using energy from the sun we can have free electricity by saving on the monthly payment for utility services, at the same reducing CO2 emissions by using clean and renewable energy source.
PV is an abbreviation of the term photovoltaic, photovoltaics gets its name from the process of converting light (photons) to electricity (voltage), which is called the photovoltaic effect.
1kW solar PV system provides on average 6000-7000 drams of saving per month. So, by dividing your monthly payment for electricity to the number mentioned above you can understand the power of the system that you need.
Area required for 1kW system is around 12-15m2 on roof or ground.
It depends on what type of system do you have.
There are mainly three types of solar PV systems:
On-grid – the system works attached to grid and if there is no power from the grid the system shuts down too.
Off-grid – the system works independent from the grid by using batteries
Hybrid – the system works both with and without grid
Besides the PV panels there is also another not less important main component called inverter which converts DC power produced by PV panels to AC and supplies it to the grid.
