SolarDraft: A Complete Guide to the Solar Draft Software for Indian EPCs (2026)
Every rooftop sale starts with a solar draft — the first layout that shows what fits on the roof and what it will produce. SolarDraft is solar draft software built for Indian EPCs to create that draft in 3D, turn it into drawings and a subsidy-ready proposal, and track the lead to signature.
What is a solar draft?
A solar draft is the preliminary design of a PV system: the roof outline and type, obstructions such as stair rooms, tanks and trees, module placement, capacity and an early generation estimate with losses. It used to need a site visit and a day of CAD work; today it can be built from a satellite map while the customer watches.
What SolarDraft includes
SolarDraft is sold as four products, each with a free plan to start:
- Solar 3D Design — design the real roof in 3D on the satellite map with LiDAR heights, run advanced shadow analysis and generate drawings and a 3D-ready proposal.
- Solar Proposal — branded, subsidy-ready proposals with PM Surya Ghar subsidy, payback and ROI, shared as a PDF.
- Solar CRM — every lead, stage and follow-up in one pipeline, linked to proposals.
- Website — a solar business website hosted on Cloudflare, from ₹10,000 one-time.

Every plan includes advanced shadow analysis, a structure BOM, PV array and string-route drawings, an SLD, a design and energy report, a shareable 3D link, and RCC, tin-shed, petrol-pump and parking roofs. The full list is on SolarDraft’s compare-plans page.
A solar draft workflow, step by step
- Find the site — search the address or drop a pin on the satellite map.
- Model the roof — LiDAR heights fill in the building and its neighbours.
- Add obstructions — stair rooms, tanks, trees and parapets.
- Place panels — fill the roof and check shading losses.
- Generate outputs — PV array and string-route drawings, SLD, BOM and energy report.
- Send the proposal — with subsidy and payback, plus a 3D link the customer can open.
- Track the lead — follow-ups in the CRM until it is signed.
Who it suits
- Residential installers handling PM Surya Ghar leads at volume — see our PM Surya Ghar guide.
- Commercial rooftop EPCs on RCC roofs and tin sheds up to 500 kW, 1 MW or 10 MW depending on plan.
- Sales teams that meet customers on site and design on an Android phone.
