What size solar panel system do I need for my home in Khammam?

For a typical home in Khammam with a monthly bill of ₹1,500–2,500, a 3 kW system is usually sufficient. Homes with bills of ₹2,500–4,000 (air conditioning, water heater) should consider 5 kW. A 3 kW on-grid system costs approximately ₹2,00,000–2,20,000 before the PM Surya Ghar subsidy of ₹78,000, bringing your net cost to around ₹1,22,000–1,42,000. Sri Ishaan Solar will size the system correctly after a free site visit and analysis of your last 3 electricity bills.

Is PM Surya Ghar subsidy available for solar in Khammam?

Yes. Khammam falls under TSSPDCL and is fully eligible for the PM Surya Ghar Muft Bijli Yojana central subsidy: 1 kW — ₹30,000; 2 kW — ₹60,000; 3 kW and above — ₹78,000 (maximum). There is no separate Telangana state top-up currently active. The subsidy is credited directly to your bank account after installation and net metering activation. Sri Ishaan Solar (TGREDCO Reg: TSRE260936) handles the complete PMSG portal registration and TSSPDCL coordination.

What is the ROI for a commercial solar system in Khammam?

A 25 kW commercial solar system in Khammam costs approximately ₹12,00,000–15,00,000 installed. At a commercial tariff of ₹6–8 per unit, monthly savings are ₹25,000–40,000. Payback period: 3–4 years. Over 25 years, a Khammam commercial unit saves ₹75 lakh to ₹1.2 crore on electricity. Tobacco processing, rice milling, and cotton ginning units see the highest ROI due to daytime-heavy load profiles that align perfectly with solar generation hours.

Can farmers in Khammam get solar for agricultural pump connections?

Yes. Farmers in Khammam with agricultural pump connections can install off-grid or on-grid solar systems to power irrigation pumps. While PM Surya Ghar is primarily for residential rooftop solar, separate central and state schemes exist for agricultural solar pumps (PM-KUSUM component A and B). Sri Ishaan Solar advises farmers on the right scheme for their pump capacity and land situation. Call +91 78424 61888 for a free consultation.

Solar Panel System in Khammam — Residential & Commercial Guide 2026

Updated May 2026 | By Sri Ishaan Solar Team

Khammam district is one of Telangana's most active zones for solar adoption — driven by high daytime electricity consumption in agriculture, tobacco processing, rice mills, and growing residential colonies. Whether you are a homeowner in Khammam town or a commercial operator in Bhadrachalam, this guide explains exactly what a solar panel system costs, how much you save, and how to claim the PM Surya Ghar subsidy in 2026.

Solar Panel System Price in Khammam 2026

All prices below are for on-grid (grid-connected) systems — the most common type for homes and businesses in Khammam. On-grid systems qualify for PM Surya Ghar subsidy and TSSPDCL net metering.

Solar Panels for Home in Khammam — What to Expect

Most residential customers in Khammam fall into the 3–5 kW range. Here is what determines your ideal system size:

Monthly bill under ₹2,000: 2–3 kW system is sufficient
Monthly bill ₹2,000–4,000: 3–5 kW system recommended
Monthly bill above ₹4,000 (multiple ACs, water heater): 5–8 kW system
Available roof area: 1 kW of panels needs approximately 8–10 sq ft of shadow-free space

A well-sized 3 kW system on a home in Khammam generates 300–360 units per month on average — enough to eliminate most of a typical household's electricity bill when combined with TSSPDCL net metering.

TSSPDCL Net Metering in Khammam District

Khammam district falls under TSSPDCL (Telangana Southern Power Distribution Company Limited). Net metering is permitted under TSERC regulations for systems up to 500 kW.

How it works for Khammam homes and businesses:

Your solar system feeds power directly into your home — you consume it first
Surplus units flow back to the TSSPDCL grid and are recorded by the bidirectional meter
Your monthly bill reflects only the net difference: units consumed minus units exported
Most 3–5 kW homes in Khammam achieve near-zero monthly bills during peak solar months (March–May, September–November)
The TSSPDCL net metering application, inspection, and bidirectional meter installation are included in Sri Ishaan Solar's turnkey price

Commercial Solar Panel System in Khammam

Khammam district's economy — tobacco curing, rice milling, cotton ginning, cold storage, and growing commercial real estate — makes it one of the most ROI-positive zones for commercial solar in Telangana.

Why Commercial Solar Works Especially Well in Khammam

Tobacco processing units: High daytime electrical load for curing fans and dryers aligns directly with solar generation hours — ROI under 3 years in many cases
Rice mills: 10–50 kW systems offset HT/LT commercial tariffs (₹7–9 per unit) and reduce demand charges
Cotton ginning and textile: Continuous daytime operations mean nearly full solar self-consumption, maximising savings
Cold storage: Refrigeration compressors run during daylight hours — ideal solar load match
Bhadrachalam paper and industrial cluster: Large rooftop areas and high consumption make 100–500 kW systems viable

See our Bhadrachalam solar installation guide for specifics on the Bhadrachalam industrial area.

Commercial System ROI in Khammam

System Size	Installed Cost	Monthly Saving	Payback	25-yr Net Saving
10 kW	₹5 – 6L	₹8,000 – 12,000	4–5 yrs	₹20 – 30L
25 kW	₹12 – 15L	₹25,000 – 40,000	3–4 yrs	₹60L – 1Cr
50 kW	₹22 – 28L	₹50,000 – 80,000	3–4 yrs	₹1.2 – 2Cr

Commercial tariff assumed at ₹7/unit. Actual savings vary by sanctioned load, contract demand, and consumption profile.
