What type of solar power systems available?
There are mainly two types of solar systems, Off-Grid (standalone) and Grid tied System, also grid tied system with battery back-up system also becomes popular recently.
Grid tied system, often located in built up areas, supply solar electricity through an inverter directly to the household or the electricity grid if the system is providing more energy than the house needs.
Off-grid (standalone) systems usually operate in remote areas, away from power supply lines or where supply can be unreliable. The electricity generated by the system is usually stored in a battery bank consisting of deep cycle batteries which are suited for repeated partial charge and discharge.
