Q&A on Solar -Power Projects

How much land is required to setup a 1MW solar power generation Unit?

The land required for a 1 MW power plant setup is around 4.5-6 acres. This is only a rough benchmark and may vary based on technology and efficiency of panels.

What is the life-time of a typical Solar Power plant?

The useful life of a typical Solar Power plant is considered to be 25 years. This is the duration for which long-term PPAs are signed and financial models are built. However, Solar Power plants can run beyond 25 years while producing a lower output. Many Solar Panel manufacturers guarantee an output of 90% at the end of 10 years and 80% at the end of 25 years.

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 an 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 basic requirements for starting the construction of a solar project?
  • Land purchase/lease
  • Power Evacuation arrangement with permission from DISCOM
  • Metering arrangements
  • Copy of PPA
  • Proposed Model and make of plant equipment
  • Undertaking for compliance with the usage of fossil fuel criteria as specified by MNRE
  • Details of Connectivity with DISCOM etc.
