Enter a PIN code, roof and load. SustivioLabs sizes the system, runs a real 25-year financial simulation on live Indian tariff and irradiance data, and hands you a branded PDF your customer can sign.
Track, Improve, Impact.
Your team fills a short guided flow. Everything downstream — sizing, subsidy, financing, emissions — is computed from real data for that exact location.
One field resolves the site. We look up the exact district, its DISCOM tariff slab, the local solar irradiance and the state's optimal tilt angle — not a national average that quietly breaks your numbers.
Usable roof area, roof type and orientation, monthly consumption in kWh or in rupees, and consumer category. The system is sized against what the roof can actually hold and what the customer actually uses.
Pick panels from the catalog or enter your own, add a battery tier if the customer wants backup, and choose self-funded or bank loan with EMI. The full quote regenerates the moment anything changes.
Every quote produces the same five things, branded to your company and ready to send.
Panel count and kW rating are solved against the usable roof area, the panel dimensions you selected and the customer's real consumption. Move the two sliders — the roof fills as the sizing engine would fill it.
Output drops about 2% in year one and 0.55% every year after, reaching 84.8% of original by year 25. Tariffs rise. Both are modelled per year, so the payback figure is a simulation result rather than an optimistic flat estimate.
The central subsidy is applied on the correct slab for the system size, and the report shows gross cost, subsidy and net cost separately — the three numbers customers compare across quotes.
Avoided CO₂ is computed with the grid emission factor for that state, then translated into trees planted and car kilometres — the part of the quote that closes conversations with sustainability-minded buyers.
A graphical dashboard version to share with the customer, and a technical version with itemized cost tables for documentation and procurement. Both carry your company's branding, not ours.
International calculators average India into a single row. Your quotes are only as accurate as the numbers behind them, so we built the numbers.
Every PIN resolved to district, state and coordinates.
Slab structures per utility, by consumer category.
State-wise solar and battery price ranges kept current.
Latitude-derived tilt per state, feeding yield estimates.
State grid carbon intensity for honest emissions maths.
