A grid connected/interactive system is connected to a large independent grid (typically the public electricity grid) and feeds power into the system and grid without battery back-up. However it can be customized to include small battery bank to provide buffer and control flexibility to allow optimum use of the renewable energy source without threatening the robustness and quality of power delivered to the customer.
Major Components :
Solar PV Module
Grid Interactive Inverters
Array Junction Boxes/DC Combiner Boxes
Required protection devices like Earthing kit, lighting protection etc.
AC Distribution Box
General working principle behind On Grid solar solution is that it is connected to photovoltaic power systems that consist of Maximum Power point tracking, Photovoltaic panels, solar inverters, power conditioning units and grid connection equipment. Dissimilar to Stand-alone photovoltaic power systems these systems not often have batteries. Grid-connected photovoltaic power systems can feed excess power to the grid, which in this case acts as a battery for the system. The assessment is done through a meter to monitor.The vast appeal of on grid solar power system has been because of the manifold benefits it provides compared to off grid and other traditional sources of power generation:
Benefits of On Grid Roof top Solar System
Low cost solar power reduces electricity cost
Reliable System with very low maintenance
Easier to install as they do not require battery system
System life more than 25 years
Efficient hedge against inflation in Grid electricity tariff
Green Energy generation help reducing carbon foot print
