A small-scale Hybridized Solar PV-AC Grid (HSPVACG) power system has been developed to operate along with AC grid. This system consists of a photovoltaic, array installed on the rooftop, a hybrid power controller (HPC) and an inverter. This newly developed (HPC) works in such a way that for a particular predetermined load the maximum available solar power is utilized and the remaining power is drawn from the AC grid. By placing the HSPVACG on the rooftop, we can avoid the use of land that is scare and expensive. Moreover the roof in the metropolitan city of Delhi is flat, which implies that system can be placed in such a way so as to get maximum output from the PV modules. The load requirement and the power flow are continuously monitored. The power generated from solar panels is given preference over grid power such that the sum of the two powers equals to the required total load for the utilization of maximum solar power. This HSPVACG power system is best suited for operation during the daytime however a battery backup of twohour duration can be incorporated for operation beyond sunshine. The system provides optimum economical use of solar PV power with a lot environmental benefits especially in an urban sector.
