Project Overview

A Jaipur homeowner transforms his electricity economics with clean solar energy

Mr. Rajesh Sharma owns a spacious 4-bedroom villa in Malviya Nagar, one of Jaipur's most sought-after residential neighbourhoods. The household hosts a family of six, with two air conditioners, a geyser, two refrigerators, washing machine, and a full range of modern appliances running through the summer months. Rajasthan's intense heat — with temperatures routinely crossing 45°C from April through June — meant the home's electricity bills were anything but modest.

By mid-2023, Mr. Sharma was paying an average of ₹12,000 per month on electricity, with peak summer months touching ₹16,000. He had explored solar previously but concerns about reliability, roof load, and the quality of workmanship had kept him from committing. After a friend installed solar through FGPS Solar and shared consistent feedback about performance and service, Mr. Sharma reached out to us for a detailed site assessment.

Our technical team conducted a thorough shading analysis, structural roof inspection, and load profiling. The villa's south-facing RCC terrace offered 480 sq ft of unobstructed space — more than adequate for an 8 kW on-grid system. We designed the system to cover approximately 80–85% of the household's annual consumption, with net metering enabling surplus export during lower-consumption winter months.

The 8 kW system uses 20 high-efficiency monocrystalline PERC panels paired with a Solis 8 kW string inverter. Installation was completed in four working days, including DISCOM inspection and net meter commissioning. The system went live in October 2023 and has been performing above projection in every subsequent month.

Key Outcomes

  • Monthly bill reduced from ₹12,000 to just ₹2,400 — an 80% reduction
  • Annual savings of ₹92,160 against a total project cost of ₹4.6 lakhs
  • Full payback expected within 5.0 years; 20+ years of near-free electricity thereafter
  • 8.3 tonnes of CO2 offset every year — equivalent to planting 370 trees
  • Net metering approved by JVVNL within 21 days of application

I was paying ₹12,000 every month and dreading the summer electricity bills. After FGPS Solar installed our 8 kW system, my bill dropped to under ₹3,000 — even in peak summer. The installation team was professional, the wiring was clean and neat, and the monitoring app tells me exactly how much power I'm generating every hour. The investment paid for itself much faster than I expected. I only wish I had done this three years earlier.
