Rooftop solar power plants has its PV panels mounted on the rooftop of a residential or commercial or industrial roof of an existing building. In urban buildings, rooftop installations are more feasible because it utilizes unused building roofs. Rooftop solar power plants are small installations in kW scale and can go up to 2 MW for large roof space. It can be installed on the building with pitched roof, flat roof, shed roof, and curved roof. Grid connected rooftop solar power plants are the most simplest and cost effective installation. It is not competent to back up power during outages. DC power generated by PV modules or array or string mounted on roof is converted to AC power by inverter, which feeds the existing load. During power generation through PV solar, power drawn from grid gets reduced. In the case of excessive power generation, energy fed backs to grid. Depending on policy, power that is pushed back into the grid is purchased by utility or adjusted in billing cycle.

GROUND MOUNT SOLAR POWER PLANTS

Ground mount solar power plants has its PV panels mounted on the flat land or marine coast or desert land. They are hundreds of kilowatts to megawatt scale power plants designed to meet energy need of industry or to add power generation in grid. Ground mount solar power plants are more productive per area than rooftop solar power plants because they are independent to fixed roof position and installed at perfect ground position that can harvest optimum energy. They are furnished with fixed tilt or single axis tracker or dual axis tracker. DC power generated by PV array is transmitted to large power inverter. AC power output of inverter is made available to grid through transformer. To maximize PV system efficiency, power plants are incorporated with maximum power point trackers (MPPT) either within the inverters or as separate units. This device keeps each solar array string close to its peak power point. The performance of ground mount solar power plants is a function of the climatic conditions, equipment used and the system configuration.

STANDALONE SOLAR POWER PLANTS

Standalone solar power plants has its PV panels mounted on either building rooftop or flat land. They are hundreds of kilowatts to megawatt scale power plants designed to meet the requirements of power for certain days when sun is not available Standalone solar power plants are integrated with large number of battery storage. Power handling capacity of standalone solar power plants are enough to feed all energy needs at the site and recharge the batteries at the same time. They are the best solution for spacecraft, remote buildings, pumps, boats, road signs, radio towers etc. DC power generated by PV array is transmitted to inverter to feed the existing load and to the battery bank to store power to be used during night. A charge controller are incorporated in the system to avoid battery damage by excessive charging or discharging. Standalone solar power system suffers from high initial and maintenance cost of batteries.
