Solar Calculator Goa 2026

Rooftop solar in Goa

Goa's power is distributed by the state-run Goa Electricity Department (GED) rather than a private DISCOM, covering homes across North and South Goa from Panaji to Margao and the coastal talukas. Domestic net metering is available up to your sanctioned load, generally to 10 kW for households, with surplus export credited against imports and settled periodically. GED terms are revised occasionally, so confirm the current net-metering and banking rules before applying.

Tariffs and typical savings

GED domestic tariffs are slab-based, rising from about 2.10 rupees per unit at the lowest slab to roughly 5.45-6.60 in the higher slabs. Air-conditioning load in Goa's humid climate pushes many homes into those upper slabs, where rooftop solar offsets the most expensive units. A coastal rooftop here yields around 4.1 units per kW per day. Convert your bill into an estimated size with our solar savings calculator or the nationwide India solar calculator. Most homes choose a grid-tied system without batteries to keep costs down; if you want backup during outages, size storage separately with the battery bank calculator.

Coastal sunshine and roof notes

Goa gets over 300 sunny days a year with strong irradiation, though the June to September monsoon sharply cuts output for a few months, so an annual average rather than a peak figure gives a fairer picture. Salt-laden coastal air makes quality mounting hardware and corrosion-resistant fittings worthwhile. A modest tilt toward true south captures the most annual energy - check yours with the solar tilt angle calculator.

How PM Surya Ghar applies

PM Surya Ghar: Muft Bijli Yojana pays 30,000 rupees per kW for the first 2 kW plus ₹18,000 for the 3rd kW, capping central support at ₹78,000 for systems of 3 kW and above, paid by DBT after commissioning. Goa is not a special-category hill state, so the standard central amounts apply; any GEDA promotional scheme is best confirmed directly. Many homeowners finance the balance with a collateral-free loan around 7% - model it in the solar loan EMI calculator.

A worked example

A 3 kW system in Panaji might generate about 4,500 units a year. Offsetting units priced near 5 rupees could save roughly ₹22,000 annually. With ₹78,000 central support cutting a gross cost near ₹1.7 lakh to well under ₹1 lakh net, payback often lands in the four-to-five year range. These are planning figures - actual output, tariffs and subsidy terms vary.

Frequently asked questions

The state-run Goa Electricity Department (GED) distributes power and processes domestic net-metering applications, generally up to 10 kW sanctioned load. Apply through the PM Surya Ghar portal along with GED, and confirm the latest banking and settlement terms before you commit.

The main incentive is the central PM Surya Ghar amount of up to 78,000 rupees. GEDA has run promotional schemes and fast-tracked approvals from time to time, but a confirmed per-kW state capital subsidy for homes is not assured - check geda.goa.gov.in for current offers.

At about 4.1 units per kW per day and upper-slab tariffs near 5 rupees per unit, a 3 kW system may generate roughly 4,500 units and save around ₹20,000 to ₹24,000 a year, depending on your consumption, AC load and the monsoon months.

Salt-laden air near the coast makes corrosion-resistant mounting and fittings important, and the June to September monsoon reduces generation for a few months. Even so, 300-plus sunny days give Goa strong year-round potential at around 4.1 units per kW per day.

About 12 units a day or 4,467 units a year on average, from about 7.1 a day in July to 15.9 a day in February, according to PVGIS data for panels at the best fixed angle. Shading, dust and orientation change the result.
