Solar PV On-grid
How it works:
When Solar PV system is connected to the electricity grid as secondary source of electricity, it’s then called Solar PV on-grid or grid-connected. It works completely without batteries. The Solar PV modules is installed on the roof, inverted is used to convert DC electricity to AC then the inverter output is connected to the building electricity distribution panel.
Finally, bi-directional meter is installed to measure both imported & exported (in and out) electricity and the customer pays for the net consumption. This is known as “Net Metering” system and it works as follows:
-
If produced energy is equal to consumed energy, the electricity bill is zero.
-
If produced energy is less than consumed energy, customer pays for net consumption.
-
If produced energy is more than consumed energy, excess production is credit for the user.
-
The electricity credit is purchased by the Electricity Distribution Company on annual basis.
Customer benefits:
-
Solar Energy is natural, clean, free and available for everyone to use!
-
Reduction in monthly electricity bills up to 100%.
-
Avoid annual electricity costs increase as solar PV system total cost is almost fixed.
-
Payback period is 4-7 years.
-
Guarantee up to 10 years and life time exceeds 25 years.
-
Least maintenance effort and cost.
-
Customization of system shape according to available area.
-
Can be made as pergola to shade the roof area.
Applications:
-
House roof top for residential sector.
-
Commercial buildings; schools, malls, administrative buildings, car parts…etc.
-
Industrial concrete buildings and steel structures.
Solar PV Pumping
How it works
Solar PV pumping system is considered one of the Solar PV off-grid applications. In the remote farms that are not connected to the electricity grid, it uses generated electricity to operate pump motors directly to pump water for irrigation whenever solar radiation is available during the day. Water storage is used to enable water usage over the 24 hours.
Advantages:
-
Solar Energy is natural, clean, free and available for everyone to use!
-
Reliable source.
-
It can operate pumps motors in wide power range.
-
Less maintenance effort and running cost compared with diesel generators.
-
Very short payback period 3-5 years.
-
Safe and risk free.
-
Applications:
-
Irrigation of remote farms with underground water.
-
Irrigation with surface pumps.
Solar PV Off-grid
How it works
The system uses Solar PV produced energy to charge batteries so that loads can be operated over the 24 days. The system can be used in remote areas that’s the electricity grid cannot reach.
Advantages:
-
Solar Energy is natural, clean, free and available for everyone to use!
-
Reliable source.
-
It can operate all home appliances.
-
Less maintenance effort and running cost compared with diesel generators.
-
Safe and risk free.
Applications:
-
Stand-alone systems for remote houses or off-grid facilities.
-
Solar street lights.
Solar Water Heating
How it works
Solar water heaters can convert the thermal energy in the solar radiation into heat. Solar collectors contain water pipes and absorb solar radiation so water inside is heated up. An isolated storage tank should be attached to keep hot water available all over the 24 hours.
Customer benefits:
-
Reduction in electricity/gas bills.
-
Most safe as it’s not inside the house and no gas or electricity risks.
-
Long time guarantee 5-10 years and least maintenance effort and cost.
-
Payback period is less than 5 years.:
Applications:
-
Domestic applications; provide hot water for home use.
-
Commercial applications; provide hot water for hotels, administration buildings, malls, schools, hospitals…etc.
-
Industrial applications; provide water pre-heating for boilers to save fuel costs.
