Roof top Solar projects require substantial coordination of different agencies, viz Net metering regulation (regulatory commission),DISCOM ( net-metering & bill settlement ) , Ministry & state Nodal Agency (for release of subsidy ) , Banks( improvement /housing loan ) ,Urban local body ,rooftop owner( access to roof ), EPC Contractors /Developers/Aggregators ( Project operation & implementation ) in accelerating speed of implementation process . For maximum utilization and optimal operation of solar plant is dependent, amongst other factor, on periodically cleaning by water. Soiling of Solar Module reduces energy generation drastically and negatively impacts on project economic.
