Question, can we generate electricity locally at our homes and sell it to the electricity company? Is this is a good investment project I can do? The answer is yes off course you can do it….. That is done by construction on grid photo voltaic system at the roof of your home.
Most of people
that construct on grid photo voltaic system aiming from that are to gain good
monthly income from the electricity company under the popular regulation
present in almost countries all over the world which called Feed in Tariff. There
are two factors affecting your success in installing excellent and reliable on
grid photo voltaic system to generate electricity and harvest good monthly
income one of them is the good design and the other is the good selection of on
grid photo voltaic system components to be according to specification.
Kindly let me
tell you a brief on how can the specialized solar photo voltaic engineers design
on grid photo voltaic system in a simple way :
First: we will ask home owner about electricity bills for
the previous 2 years to indicate the average monthly electricity consumption
and also ask him about his budget.
Second: we start to go to the roof area to indicate its
characteristics by identifying the usable area that is suitable for installing
the photovoltaic system (eliminating spaces of local and horizontal shadow) and
indicting the roof azimuth and tilt angle which related to the good facing to
the sun to get maximum electricity harvest.
Third: we select a photo voltaic modules type and
manufacture from many various manufacturers present all over the world and
racking system if needed. By knowing the size of module and racking system I
will indicate the maximum number of modules I can installing at the roof and consequently
the maximum electrical power I can gain from the array.
Fourth: by indicating the array max electrical power we
can get the rated power of the inverter we will install.
Fifth: by using
software or by some calculation we indicate number of array strings and maximum
/minimum number of modules in each string.
Sixth:
by knowing the sun hours in the city and in my
specific roof under design I can calculate the electricity that can be
harvested each month then I will do my feasibility study introducing it to the
home owner.
It's an
effective and guaranteed project to generate electricity and sell it to Electricity
Company by constructing on grid photo voltaic system … I am in help to my colleagues
, any home owner or anew electrical engineer . all of your inquires are welcome
