A grid connected photovoltaic power system is an electricity generating solar PV solar system that is connected to the utility grid. A grid connected PV system consist of solar panels, one or several inverters, a power conditioning unit and grid connection equipment. They range from small residential and commercial rooftop systems to large utility-scale solar power stations. Unlike stand-alone power systems, a grid-connected system rarely includes an integrated battery solution, as they are still very expensive. When conditions are right, the grid-connected PV system supplies the excess power, beyond consumption by the connected load, to the utility grid.
1) Have access to power continuously all the time.
2) Not having any scheduled or unscheduled power cuts.
3) Not dependency on diesel.
4) The quality of power is superior to the regular grid power.
5) Low and optimum maintenance cost.
6) Stable supply of power increases the overall efficiency of electronic components.
7) Batteries design for longer life.
1) Solar street lights are raised light sources which are powered by solar panels generally mounted on the lighting structure or integrated in the pole itself. The solar panels charge a rechargeable battery, which powers a fluorescent or LED lamp during the night not having any scheduled or unscheduled power cuts.
2) Solar street lights are independent of the utility grid. Hence, the operation costs are minimized
3) Solar street lights are independent of the utility grid. Hence, the operation costs are minimized
4) Batteries design for longer life.
Solar water heating (SWH) is the conversion of sunlight into heat for water heating using a solar thermal collector. A variety of configurations are available at varying cost to provide solutions in different climates and latitudes. SWHs are widely used for residential and some industrial application.
A solar-powered pump is a pump running on electricity generated by photovoltaic panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity run water pumps. The operation of solar powered pumps is more economical mainly due to the lower operation and maintenance costs and has less environmental impact than pumps powered by an internal combustion engine (ICE). Solar pumps are useful where grid electricity is unavailable and alternative sources (in particular wind) do not provide sufficient energy.
