Tamil Nadu support applies to the first 1 lakh eligible beneficiaries registered on the PM Surya Ghar portal from 5 August 2026, subject to allocation and approval. The calculator models state support for systems up to 10 kW.
Residential connections only. Follow portal approval, registered-vendor, domestic-content equipment and commissioning requirements. Subsidies are paid after approval; they are not an upfront discount. Commercial installations do not qualify for these household subsidies.
Tariff, costs & calculation assumptions
Domestic LT I-A tariff, including free-unit benefits. Official tariff ↗ · Verified 28 October 2026.
We model 120 units per kW each month, 110 sq ft of usable roof per kW, and 70% direct self-consumption. Savings compare energy charges before and after solar using the verified tariff schedule. Export credits are excluded; Tamil Nadu net feed-in credits are not assumed to equal retail electricity rates. Fixed charges, taxes and commercial peak charges may remain.
System budgets are planning ranges, not a final installation quote or tax invoice. The 1–3 kW ranges follow the state solar portal; larger systems use ₹55,000–₹70,000 per kW as an illustrative allowance. Batteries, financing, unusual structural work, maintenance and site-specific statutory charges are excluded. Final taxes, equipment and installation scope require a written quotation. Subsidies arrive after approval and commissioning, so budget for the full upfront cost. Actual sunlight, shading, consumption and scheme availability affect results.

Good questions.
Clear answers.
Where does Arc Solar install rooftop solar?
Arc Solar accepts home and business enquiries across Vellore, Tirupattur, Ranipet, Chennai, Kanchipuram. Priority towns include Pernambut, Vellore, Ambur, Gudiyattam, Vaniyambadi. Speak directly with the owner to confirm your location, roof assessment and appointment availability. These are service areas, not separate branches.
Can I choose a smaller system to fit my budget?
Yes. The calculator suggests a capacity from your electricity units, but you can choose any whole-kW size from 1 to 30 kW. It recalculates the planning budget and generation for your choice. The final installation size depends on roof suitability, electrical requirements and the written quotation.
How do I get an estimate or request a callback?
Enter the units consumed on your one- or two-month electricity bill, choose home or business, then select your preferred kW. Download the two-page budget PDF without sharing personal details. To discuss the estimate, use WhatsApp, call the owner, or leave your number in the callback form beside it. The estimate is indicative; a site assessment and equipment specification determine the final quote.
Is my roof right for solar?
A good starting point is usable, structurally sound roof space with limited shade. Orientation, local weather, access, and your electricity connection also matter. The calculator gives a first estimate; a site assessment confirms what will work.
What happens when the sun goes down?
A grid-connected system uses electricity from the grid when solar production is low. Adding a compatible battery lets you store some daytime production for later. Backup during a grid outage requires equipment specifically designed and configured for that purpose.
Do solar panels need maintenance?
Panels need periodic inspection and appropriate cleaning, especially where dust, leaves, or bird droppings reduce sunlight. Cleaning frequency depends on the location. Electrical work and rooftop access should be handled by qualified professionals.
