SOLAR ROOFTOP PROJECT- 100 KW GRID CONNECTED
100 KW GRID CONNECTED SOLAR ROOFTOP PROJECT
Faculty Higher Secondary School is a private school in Amingaon, Guwahati-781039, Assam, India part of Osom Educational Trust, which is a Non-profit Organization. The Area trustee of organization P.K. Bhuyan and B. Bhuyan.

It is a Day school with limited Hostel facilities for neighboring states like Arunachal Pradesh, Nagaland, Manipur, Meghalaya, Sikkim, and Mizoram. The hostel is air-conditioned.
We had approached the organization in October 2017, for the Grid connected Rooftop Solar power project with subsidy under RESCO mode. At that time we were empaneled with state Nodal Agency i.e.; Assam Energy Development Agency for the 14 MW grid connected RTSPV project with 70 % subsidy. In the RESCO mode the tariff were fixed @3.43/KWh for the 25 years. The organization don’t need to invest single penny for the project whole cost will be worn by Govt. in form of subsidy and the Developer.
We have made them understand about the viability of the project to offset the increasing bill amount of the Grid. After all discussion we have signed a PPA for the period of 25 years with complete O&M under our scope. There were two connection of Discom with Connected load of 70 kW and 72 kW respectively.
According to the APDCL Rooftop Solar guideline max. 80 % of connected Load can we Solarize. So, we went with 50 kW each on both connection.
