SolarDraft (also searched as Solar Draft) and Reslink Energy are both India-born, mobile-first platforms covering 3D design, proposals and lead management for solar EPCs. Reslink's publicly reported scale is larger — it lists adoption across residential rooftop through utility-scale projects (3 kW to 1 GW) and operations in India, the US, the UK, Europe and APAC, plus a separate IoT monitoring product called Reslink Intelligence.
That difference in scope is the thread running through this comparison. Below we cover what each platform is built for, how the day-to-day workflow compares for an Indian rooftop EPC, how pricing works, and the questions worth asking before you commit to either.
Key points
- Both platforms are built in India and cover 3D design, proposals and lead management.
- Reslink positions itself for a very wide project range (3 kW to 1 GW), several countries and post-installation IoT monitoring.
- SolarDraft focuses on Indian residential and C&I work: subsidy-ready, GST-inclusive proposals, engineering drawings and a built-in CRM at published prices.
- Decide by scope: if you need gigawatt-scale or plant monitoring in one vendor, evaluate Reslink; for fast, transparent Indian rooftop sales, SolarDraft is built for that.

Key features — SolarDraft
- 3D Design, Proposal and CRM, each with published Basic, Pro and Premium prices, GST included.
- Built specifically around Indian subsidy and GST requirements.
- Simple tier structure — see the full Price List.
- Roof and site types Indian EPCs actually quote on: RCC, tin-shed, petrol pump canopies, parking structures, and ground mounts and agrivoltaics on Pro and above.
Key features — Reslink Energy (per public information)
- Handles a very wide project range, from small rooftops to gigawatt-scale.
- Reports rapid adoption and a multi-country footprint.
- Offers post-installation IoT monitoring through Reslink Intelligence.
“If you need one platform that also monitors the plant after commissioning, look at Reslink's IoT add-on. If you want simple, fixed-price plans for Indian rooftop and C&I sales, SolarDraft is built for that.”
Workflow for an Indian rooftop EPC
Most Indian EPCs spend their week on 2–10 kW homes and 20–500 kW commercial roofs. For that work, the steps that matter are the same every time:
- Model the real roof — SolarDraft's Solar 3D Design places panels on the actual roof geometry, with LiDAR where available, and runs a year-round shading analysis.
- Get the engineering outputs — Structure BOM, PV array and string route drawings, and a Single Line Diagram come from the same design.
- Send a proposal the customer trusts — the Solar Proposal shows gross cost, the PM Surya Ghar subsidy and the net cost separately, with payback and generation.
- Follow up until it closes — the Solar CRM tracks each lead's stage and next follow-up.
When the wider scope matters
If your pipeline genuinely spans small rooftops to utility-scale plants, or you operate across several countries, a platform built for that breadth may suit you. The same goes for monitoring: if you sell O&M contracts and want plant data in the same vendor's system, Reslink's IoT add-on is the relevant feature to evaluate.
If your business is Indian residential and C&I rooftop — the large majority of EPCs — the deciding factors tend to be how quickly a salesperson can produce an accurate, subsidy-ready proposal and how well leads are followed up. Read what to look for in proposal software for a fuller checklist.
Pricing and buying experience
SolarDraft publishes fixed yearly INR plans for 3D Design, Proposal and CRM, with GST included, so you can budget before speaking to anyone. Solar 3D Design plans are priced mainly by the largest project size:
| SolarDraft 3D plan | Price a year (incl. GST) | Largest project | 3D designs a year |
|---|---|---|---|
| Basic | ₹40,000 | 500 kW | 365 |
| Pro | ₹60,000 | 1 MW | 500 |
| Premium | ₹2,00,000 | 10 MW | 2,000 |
| Custom | Quote | Above 10 MW | Unlimited |
Per available information, Reslink's pricing isn't listed on its own site, so you'll need a sales conversation to compare. Either way, ask for the full annual cost for your team, including any per-user or per-project charges, and whether GST is included.
Which should you choose?
| If your business… | Worth evaluating first |
|---|---|
| Sells residential rooftop under PM Surya Ghar | SolarDraft |
| Does C&I rooftops up to 10 MW and wants published prices | SolarDraft |
| Needs design, proposal and CRM with engineering drawings | SolarDraft |
| Runs gigawatt-scale projects across several countries | Reslink Energy |
| Wants IoT plant monitoring from the same vendor | Reslink Energy |
How to run a fair trial
- Pick one residential and one commercial roof from your current pipeline.
- Design both in each platform and compare the layout and shading result.
- Generate proposals and check the subsidy, GST, generation and payback.
- Ask your installers which drawings they could build from.
- Compare the full yearly cost for your team.
Both are credible options for an Indian solar EPC. The practical difference is scope: Reslink positions itself for a wider range of project sizes and geographies plus post-install monitoring, while SolarDraft focuses on getting Indian rooftop and C&I deals designed, proposed and tracked at a transparent, published price.
FAQ
Does SolarDraft handle commercial projects?
Yes. 3D plans cover projects up to 500 kW (Basic), 1 MW (Pro) or 10 MW (Premium), and larger projects on a Custom plan. See commercial vs residential solar for how those projects differ.
