Sikar Residence — 6 kW Rooftop Solar

📍 Sikar, Rajasthan | Completed June 2024
Mr. Bharat Shekhawat's two-storey home in Sikar's Fatehpur Road residential colony runs a typical middle-class household load: two ceiling fans, two table fans, an inverter AC (1.5 ton) in the master bedroom, a refrigerator, washing machine, water geyser, LED lighting across eight rooms, and a single-phase water pump for the overhead tank. Monthly bills averaged ₹9,000 — a significant expense in a city where household incomes are substantially lower than Jaipur or Delhi.
Mr. Shekhawat had researched solar independently for over two years but held back for two reasons. First, he was uncertain whether the PM Surya Ghar Muft Bijli Yojana subsidy would apply to his AVVNL connection, and second, his roof had a south-facing RCC terrace of only 35 m² available — the rest being occupied by a staircase cover, overhead water tank, and a small servant quarter extension. He wasn't sure if a meaningful system could fit in that space.
Our site assessment confirmed that 35 m² of clear south-facing terrace was sufficient for exactly 14 panels at a 20° tilt, providing 6 kW of peak capacity — perfectly matched to the household's consumption profile of approximately 720 units per month. We confirmed subsidy eligibility under the PM Surya Ghar scheme (₹78,000 for 3 kW + additional for 6 kW bracket), reducing the net project cost to approximately ₹3.45 lakh.
The system uses a single-phase on-grid string inverter with net metering via AVVNL. Given the small roof area, precise panel spacing was critical to prevent any inter-row shading even in December when Sikar's solar altitude drops to approximately 41° at noon. Our shade simulation confirmed zero shading losses throughout the year within the 35 m² layout.
Installation was completed in two days by a four-person team. The AVVNL net-metering application was filed by FGPS Solar on behalf of Mr. Shekhawat, and the bi-directional meter was installed within 14 days — the system went live on 18th June 2024, perfectly timed to capture Sikar's peak summer generation (Sikar averages 9.4 peak sun hours in June, among the highest in India).

Average across all months including Sikar's extreme summer (May–July) and moderate winter (November–February).
Sikar is one of India's sunniest districts, with Global Horizontal Irradiance (GHI) averaging 5.8 kWh/m²/day annually and exceeding 7.2 kWh/m²/day in peak summer months. This exceptional solar resource means the 6 kW system generates over 1,400 units per month in May and June — significantly more than the household's actual consumption — creating large net-metering credits that offset winter months when generation falls to around 600 units per month.
The ₹69,120 annual saving on a net project cost of ₹3.45 lakh (after subsidy) gives a clean 5.0-year payback. What makes this project notable is that Mr. Shekhawat accessed the full government subsidy — often a bureaucratic challenge — through FGPS Solar's in-house MNRE portal team, which filed and tracked the application to completion without Mr. Shekhawat needing to visit any government office.
Post-payback, the household will save approximately ₹17–20 lakh over the remaining 20-year panel life — a substantial sum for a middle-income family in a Tier-2 city. Mr. Shekhawat has since encouraged four neighbours on the same street to go solar with FGPS Solar, two of whom have already had systems installed.
I had been reading about solar for two years but I thought it was complicated and only for big bungalows. FGPS Solar came and told me my small terrace was enough, they handled the government subsidy application themselves, and within three weeks I had a working system. My June bill — which is usually ₹12,000 in peak AC season — was only ₹1,800. My family couldn't believe it. Now four of my neighbours have gone solar through FGPS Solar because of this.
Even 30–40 m² of rooftop is enough to cut your electricity bill by 70–80%. Check your subsidy eligibility and get a savings estimate today.
