Solar FAQ

In Guntur, residential solar typically pays back in 4–5 years. Commercial systems pay back in 3–4 years. Industrial systems can have a payback as low as 2.5–3.5 years due to high electricity tariffs. With a 25-year panel life, you get 20+ years of virtually free electricity after payback.

Yes! We have tie-ups with multiple banks and NBFCs that offer solar loans at 7–9% interest. Many clients finance their systems with 0 down payment and the monthly EMI is often less than their old electricity bill — making it profitable from day one.

The ideal system size depends on your monthly electricity consumption. A rough guide: if you use 150–200 units/month, a 2–3 kW system works. 300–400 units/month needs a 4–5 kW system. 500+ units/month needs 6–8 kW. We conduct a free energy audit to recommend the exact right size for your home.

PM Surya Ghar Muft Bijli Yojana is a central government scheme providing up to 300 units/month free electricity to residential solar customers. It offers direct subsidy of ₹30,000 for 1–2 kW systems and ₹78,000 for 3 kW+ systems. We handle the entire application process for free.

You don't need to do anything! Prime S&S handles the entire subsidy application on your behalf — from registration on the national portal, to DISCOM approval, to getting the subsidy credited to your bank account. It's included in our service at no additional charge.

Central subsidy is only for residential systems. However, commercial and industrial systems get 80% Accelerated Depreciation (AD) benefit which is a major financial advantage. Businesses can also avail MSME loans, SIDBI green energy loans, and state-level incentives in Telangana.

PM-KUSUM (Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan) is a scheme for farmers providing 60% subsidy on solar water pumps and agri-solar systems. Farmers pay only 10% upfront, with 30% as a loan. This eliminates diesel pump costs completely. We assist Andhra Pradesh farmers with the full application.

In Guntur, each 1 kW of solar generates approximately 4–5 units per day (average annual). So a 5 kW system generates 20–25 units/day, or 600–750 units/month. Guntur is ideal for solar with 300+ sunny days annually and 5.5+ peak sun hours per day.

Yes, solar panels work on cloudy days at reduced output (typically 20–40% of peak). During Guntur's monsoon (June–September), generation drops but doesn't stop. The strong summer sun (March–May) more than compensates for the monsoon dip — annual average generation remains consistent.

With net metering, excess solar power is exported to the DISCOM grid. You receive credits for exported units at the applicable tariff rate. These credits offset your night-time consumption from the grid. At the end of the billing cycle, you only pay for the net units consumed from the grid — which is often zero or very low.

We only install Tier-1 certified solar panels from reputable manufacturers including Adani Solar, Waaree, Vikram Solar, Tata Power Solar, and Longi. For inverters, we use trusted brands like Growatt, SMA, Fronius, Delta, and Sungrow. We never compromise on quality.

Residential installations (1–10 kW) typically take 1–2 days for physical installation. The entire process from survey to commissioning takes 2–3 weeks, including design, material procurement, DISCOM approval, and net meter installation. Commercial/industrial projects take 2–6 weeks depending on scale.

A 1 kW solar system needs approximately 60–70 sq ft of shadow-free rooftop area. So a 5 kW system needs around 300–350 sq ft. The roof should have minimal shading between 9 AM and 5 PM for maximum output. Our engineers assess your specific roof during the free site survey.

Absolutely safe. Our certified installation team uses industry-standard mounting structures that are tested for wind loads up to 130 km/h. The panels are sealed against water ingress. We provide a 5-year workmanship warranty on installation. Proper installations never damage roofs — in fact, solar panels protect roofs from UV and heat.

In Guntur, we recommend cleaning solar panels once every 4–6 weeks during dry summer months and after dust storms. Dirty panels can lose 15–25% efficiency. Our AMC plans include quarterly professional cleaning with performance testing to keep your system generating at peak output.

Our AMC covers: 4 professional panel cleanings per year, 2 inverter health checks, 1 complete annual electrical and structural audit, 24/7 remote monitoring with alert notifications, priority support for any issues, and a detailed annual performance report. AMC pricing starts at ₹2,500/year for residential systems.

Quality solar panels last 25–30 years and come with a 25-year linear performance warranty (minimum 80% output at year 25). String inverters typically last 10–12 years and may need replacement once over the system's lifetime. Microinverters last 20–25 years. We help with inverter upgrades when needed.
