Homestays: a tariff reason to go solar
Sikkim’s 2026–27 tariff order bills homestays in urban areas at domestic rates where a rooftop solar plant of 2 kWp or more is installed. We size the plant and file the paperwork.

Rooftop solar in Gangtok and Sikkim
Homes, homestays, hotels and industry. Every hill roof simulated.
Sikkim has its own regulator, its own tariff and its own rule for homestays. Solarverse Solutions designs and installs rooftop, hybrid and off-grid solar across Sikkim from Sevoke Road, Siliguri, as an authorised Waaree channel partner, and simulates every hill roof before quoting a number.
Gangtok & Sikkim at a glance
| Electricity supplier | Energy & Power Department, Government of Sikkim |
|---|---|
| Rooftop rules | SSERC (Grid Interactive Solar PV Systems) Regulations, 2021, with group and virtual net metering from 1 to 500 kWp under the Commission’s 2023 guidelines. Surplus carries forward as energy credit within the settlement period. |
| Expected generation | About 3.0 to 3.4 units per kWp a day as a planning figure, but every hill roof is simulated on its own |
| Sunshine on flat ground | 4.07 kWh per m² a day on average; strongest in April (4.7), weakest in January (3.5) |
| Noon sun | 39° above the horizon on 21 December, 86° on 21 June |
| Daylight | 10 h 25 min on 21 December, 13 h 52 min on 21 June |
| Winter parapet shadow | A 3 ft parapet on the south edge shades about 3.7 ft of roof at noon on 21 December, and 5.0 ft at 9 am. Panels start beyond it. |
| Home subsidy | PM Surya Ghar, with about 10% higher central assistance in special-category states such as Sikkim. DCR panels only. How it works. |

Local know-how
What is different about Gangtok & Sikkim
Industry in the Rangpo belt
Units along the Rangpo–Majitar–Singtam stretch run long daytime shifts, a good match for solar. On HT time-of-day connections, Sikkim sets surplus off against the peak blocks too.
Hybrid and off-grid
Where the line is long or unreliable, a hybrid plant with lithium batteries keeps critical loads running; where there is no line, an off-grid plant does the whole job.
Every hill roof simulated
Slope, aspect, the ridge across the valley and monsoon cloud change output from one roof to the next, so we simulate each site.

Questions
Asked in Gangtok & Sikkim
Do homestays in Sikkim pay a lower tariff with rooftop solar?
In urban areas, yes. Sikkim’s tariff order for 2026–27 applies domestic rates to homestays in urban areas where a rooftop solar plant of 2 kWp or more is installed. Check your connection category with us before sizing the plant.
Is net metering available in Sikkim?
Yes, under the SSERC (Grid Interactive Solar PV Systems) Regulations, 2021. Group and virtual net metering are also allowed for plants from 1 to 500 kWp under the Commission’s 2023 guidelines, useful when one roof should serve several connections.
Does PM Surya Ghar apply in Sikkim?
Yes. Sikkim is a special-category state, so central assistance for homes is about 10% higher than in West Bengal. Panels must be DCR. See how the subsidy works.
