What is the difference between off-grid and on-grid photovoltaic power systems?
The total energy generated from the off-grid photovoltaic power system meets the desired electrical load of households and recharges the batteries, whereas the excess electricity from the on-grid photovoltaic power system feeds the grid. The two designed systems are environmentally friendly and economically viable.
Can off-grid solar energy systems be used in households?
Off-grid and on-grid solar energy systems can be used in households. Hassan et al. presented a design and analysed the off-grid photovoltaic (PV) system for village electrification in a rural site in Iraq. Their study confirmed that the use of PV systems for electrification is suitable for long-term investments with the cost of $0.51/kWh.
What is PV on-grid power system?
The proposed PV on-grid power system provides excess electricity to the grid requires cheaper energy cost than the off-grid power system and is suitable to supply energy to the grid. - For the power system consist (PV = 4.275 kW PV, battery = 2.4 kW) at off-grid (scenario A), the expected total NPC is $6,244, and the COE is $0.196/kWh.
Is an off-grid photovoltaic system a good choice?
While not a bad choice, an off-grid photovoltaic system is still unpractical when grid connection is available. The final system configuration is able to supply electricity for all weather conditions, but it's quite expensive with high initial investments.
