PROJECT OVERVIEW

500 kW β€” Desert Solar Farm, Jaisalmer

This 500 kW ground-mounted solar power plant was developed on 2.5 acres of dry scrub land on the outskirts of Jaisalmer β€” one of India's sunniest locations with an average global horizontal irradiance of 6.8 kWh/mΒ²/day. The project was developed for a private landowner under the RERC open-access framework, with the generated electricity sold to an industrial consumer 40 km away via RVPNL's intra-state transmission network.

FGPS Solar used single-axis horizontal trackers to maximise energy harvest, increasing generation by 18–22% compared to a fixed-tilt installation. The mounting structure was designed per IS:875 Part 3 for the high-wind zone applicable to the Thar Desert region. Eight 63 kW three-phase string inverters feed into a 400V MV transformer, which steps up to 33 kV for grid injection.

The project secured all RVPNL interconnection approvals, RERC open-access charges approvals, and RPO compliance certificates within 90 days of financial closure. Generation data is monitored via a SCADA system with 15-minute interval logging.

RESULTS & IMPACT

Measured Outcomes

  • 8,00,000 units generated annually β€” well above P50 estimate due to tracker gain.
  • β‚Ή48L/year income from open-access sale at β‚Ή6/unit effective delivered rate.
  • Payback in 3.4 years; project IRR of 22% over 25-year asset life.
  • 5,76,000 kg of COβ‚‚ offset every year, equivalent to planting 26,000 trees.
