How much land is required to setup a 1MW solar power generation Unit?
What is the life-time of a typical Solar Power plant?
What is the annual energy generated from a 1 MW Solar Power plant?
The usual benchmark for energy generated from a 1 MW Solar Power plant is considered as 1.5 Million units. This is only a benchmark and should not be considered as the actual output for a given location. The amount of actual energy generated from a Solar Power Plant in a year depends on both internal and external factors. External factors which are beyond the control of a solar developer can include the following:
- Number of sunny days
- Solar Irradiation
- Day Temperatures
- Air Mass
The output also depends on the following internal factors all of which are within the control of a Solar Developer:
- Plant Location
- Usage of Solar Tracking systems
- Quality of equipment used
- Workmanship of the EPC contractor
- O&M activities
What are the various modes under which we can setup a Solar Power plant?
The various modes under which a Solar Power plant can be setup depends on the specific requirement. All the following are valid modes and the costs for each kind of system varies based on various factors:
- Off-Grid Captive Consumption for domestic premises.
- Off-Grid Captive Consumption for commercial premises
- Grid Connected (Net Metered) Captive Consumption for domestic premises
- Grid Connected (Net Metered) Captive Consumption for commercial premises
- Sale of Power generated to local Distribution Company (DISCOM)
- Sale of Power generated to 3rd Party consumer (Industry or Commercial entity)
What is the cost of setting up a Rooftop Solar Power plant for domestic or commercial use?
What size Solar Power plant is required for domestic or commercial use?
Identifying the Solar Power plant size for your domestic or commercial premises depends on the following factors:
- In case when you need to shift your solar power system one location to another, we are happy to assist you.
- We will do free site inspection in your new location and propose our recommendations for smooth transition.
Setup Costs and Power Sale Tariff
What would be the per unit expected sale price?
This depends on the mode of sale of power and the consumer of power.
- In the case of sale of power to DISCOM, the prevailing Average Pooled Power Purchase Cost (APPC) will be applicable.
- Solar Irradiation
- In the case of sale of power to 3rd Party consumer, a mutually agreed price can be agreed upon and accordingly a PPA can be signed.
It is to be kept in mind that several additional charges such as Wheeling Charges, Distribution Charges, Open-Access Charges, Cross-Subsidy Charges are applicable in the case of sale of power to 3rd party. These charges vary from State-to-State and DISCOM-to-DISCOM and even based on voltage levels.
What would be the total project cost excluding the cost of land?
Total project cost per MW would be in the range of Rs.5.5 Crores-Rs.7.0 Crores depending on the kind of technology you are using, whether or not you are using tracking systems, the kind of EPC Contractor you choose for power plant system etc. CERC recently announced the benchmark tariff for setup of Solar PV and Thermal Plants in India.

Which kinds of Solar Power plants are eligible for REC benefits?
Solar Power Plants need to be Grid-Connected on order to avail REC benefits. Though there have been recommendations on multiple occasions that Off-Grid Solar Power plants be made eligible for RECs, the proposal is still under discussion. Solar Power plants setup under the following 3 modes are eligible for REC benefits.
- Captive Power plants.
- Sale of power to Govt. at APPC
- Sale of power to 3rd party at mutually agreed price.
Captive Power Plants are eligible for RECs subject to the condition that Concessional/Promotional Transmission or Wheeling Tariffs and/or banking facility benefit are not availed. Also, Solar Power plants setup under Preferential Tariff schemes are not eligible for RECs. Check out more information on RECs on REC page here –
