Rooftop solar in Gujarat: how the numbers work

Gujarat is among India's most solar-friendly states, with abundant sunshine, a mature rooftop programme and one of the highest counts of installed home systems in the country. If you are weighing a rooftop plant, the three levers that decide your return are your distribution company's net-metering rules, your residential tariff and how many units each kilowatt of panels generates. Our India solar calculator lets you plug in these Gujarat-specific values.

Your DISCOM and net metering

Most Gujarat homes are served by one of the four GUVNL companies — UGVCL, MGVCL, DGVCL and PGVCL — while Ahmedabad, Gandhinagar and Surat fall under private Torrent Power. Under GERC net-metering rules, your bi-directional meter records import and export, and any surplus you send to the grid offsets the units you draw at night. Unused credits are typically settled at the financial year end at a fixed rate. Net metering is the reason an on-grid system pays back well here, since you avoid batteries and lean on the grid as free storage.

Tariffs and why solar pays

Residential tariffs in Gujarat are slab-based and, at higher consumption, run to roughly Rs 6 to Rs 8 per unit once fixed and fuel charges are added. As of 2026, confirm your exact slab on a recent bill. The higher your tariff and monthly usage, the more each self-consumed solar unit is worth, which is what our savings calculator models.

Sunshine and generation

Gujarat enjoys around 5.5 peak sun hours a day, so a well-sited 1 kW array generates roughly 4.5 units daily, or about 1,600 units a year. Shading, orientation and dust reduce this, so keep panels clean.

PM Surya Ghar subsidy

The national PM Surya Ghar: Muft Bijli Yojana pays Rs 30,000 per kW for the first 2 kW and Rs 18,000 for the 3rd kW, capping at Rs 78,000 for systems of 3 kW and above; residential connections up to 10 kW qualify. The subsidy arrives by DBT to your bank after commissioning, and collateral-free loans near 7 percent are available. As of 2026 Gujarat runs this through the national portal without a confirmed extra state top-up, so check the latest with your DISCOM.

A quick worked example

A 3 kW system generating about 4.5 units per kW yields roughly 13.5 units a day. At around Rs 7 per unit that is close to Rs 2,800 a month in avoided or credited electricity. After the Rs 78,000 subsidy, many Gujarat homes see payback in about 4 to 5 years. Size it precisely with our system size calculator and check loan EMIs on the solar EMI calculator.

Frequently asked questions

The four GUVNL companies — UGVCL, MGVCL, DGVCL and PGVCL — plus private Torrent Power in Ahmedabad, Gandhinagar and Surat all support residential net metering under GERC rules. Your surplus units offset grid imports, with year-end settlement of leftover credits.

Under PM Surya Ghar you get Rs 30,000 per kW for the first 2 kW and Rs 18,000 for the 3rd kW, capped at Rs 78,000 for 3 kW and above. It is paid by DBT after commissioning. As of 2026 there is no confirmed extra Gujarat state top-up, so verify current terms with your DISCOM.

With roughly 5.5 peak sun hours daily, 1 kW of rooftop solar in Gujarat produces about 4.5 units a day, or near 1,600 units a year. Actual output depends on roof orientation, shading and how often you clean the panels.

A rough rule is to divide your monthly units by about 120 to get the kW needed, since 1 kW yields around 120 units a month here. A typical family with a Rs 2,500 to Rs 3,500 bill suits a 3 kW system. Use our system size calculator to match it to your roof and load.
