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.
