Rooftop solar in Telangana: TGSPDCL, TGNPDCL and net metering

Telangana has two distribution companies. Most of the state, including Hyderabad and the south, is served by TGSPDCL (the Southern Power Distribution Company, formerly TSSPDCL), while the northern districts fall under TGNPDCL. Both operate under the same state regulator (TGERC) and follow broadly the same rooftop rules, so the solar process feels similar wherever you live in the state.

How net metering works here

Under the state rooftop policy, domestic consumers can connect under net metering, with single-phase homes typically limited to about 5 kW and three-phase connections allowed larger. Your exported units are netted against imported units, and the account is usually reconciled on a half-yearly settlement around June and December, with any leftover surplus paid at a rate set by TGERC. Rooftop consumers also benefit from exemptions on items like cross-subsidy surcharge and electricity duty on the solar portion.

• Two DISCOMs: TGSPDCL (south, incl. Hyderabad) and TGNPDCL (north).
• Net metering with roughly half-yearly settlement of surplus units.
• Domestic tariff is telescopic; higher-usage homes cross into steeper slabs, so a representative rate near 7.5 rupees per unit is a sensible default.

Sunshine and generation

Telangana sits on the Deccan plateau and enjoys strong, reliable sun for most of the year, with a shorter and less intense monsoon than the coastal states. That supports a healthy yield of about 4.4 units per kW per day as an annual average. Summers are hot, which nudges panel efficiency down slightly, but overall the state is well suited to rooftop solar.

PM Surya Ghar subsidy

The central PM Surya Ghar: Muft Bijli Yojana pays 30,000 rupees per kW for the first 2 kW, adds 18,000 for the third kW, and caps at 78,000 rupees for systems of 3 kW and above, allowed up to 10 kW. It arrives as a direct bank transfer after your system is commissioned and inspected, and collateral-free loans near 7 percent are available. Telangana does not have a confirmed extra state subsidy on top of this today, so be wary of inflated subsidy promises. Right-size the system with our system size calculator and check EMIs on the solar loan EMI calculator.

A quick worked example

Consider a 3 kW system in Hyderabad. At about 4.4 units per kW per day it produces roughly 13.2 units daily, close to 400 units a month averaged over the year. Offsetting units worth around 7.5 rupees each, that is near 3,000 rupees of monthly value, subject to your slab and export mix. After the 78,000 rupee subsidy, payback usually lands within a few years. Businesses can compare the commercial solar calculator, or start from the India solar calculator.

Frequently asked questions

It depends on your location. TGSPDCL (formerly TSSPDCL) covers Hyderabad and the southern districts, while TGNPDCL covers the northern districts. Both follow the state net-metering policy set under the TGERC regulator.

Under net metering your exported units are netted against imported units, and the account is typically reconciled on a half-yearly basis around June and December, with any remaining surplus compensated at the rate fixed by TGERC.

The national PM Surya Ghar subsidy applies: 30,000 per kW up to 2 kW, plus 18,000 for the third kW, capped at 78,000 rupees for 3 kW and above, paid by bank transfer after commissioning. No separate Telangana state top-up is confirmed at present.

With strong Deccan sunshine we assume about 4.4 units per kW per day on an annual average, so a 3 kW system makes roughly 400 units a month. Hot summers trim panel efficiency a little, but the state remains well suited to rooftop solar.
