Arka360 served Indian residential installers well when affordable, India-tariff-aware design software was scarce. By 2026 the engineering depth gap with international cloud platforms has widened, and the per-quote pricing has crept up. So you are searching for an Arka360 alternative that delivers bankable simulation and AI 3D roof modeling without giving up the India-specific subsidy auto-fill.
The 2026 answer is SurgePV, built by the Heaven Group team. India-native PM Surya Ghar workflow, plus the bankable 8,760-hour simulation Arka360 does not ship.
Key takeaway. SurgePV is the best Arka360 alternative in 2026 for Indian EPCs. It keeps PM Surya Ghar auto-calc and IS code rules, adds AI 3D satellite roof modeling, 8,760-hour bankable simulation, white-label proposals, and global code coverage. $1,299 per user per year for teams of five.
TL;DR
Why Indian installers leave Arka360. Light engineering depth, no bankable yield, manual 3D modelling. Why SurgePV wins. India context preserved, bankable engineering depth added. Book a free SurgePV demo.
Why Indian installers look for an Arka360 alternative
Light engineering depth
Arka360 ships a usable residential workflow. The simulation behind the proposal is light. For lender-acceptable P50/P75/P90, you either bolt on PVsyst or outsource to a consultant.
Manual 3D modelling
The 3D roof has to be drawn from scratch on each site. No AI satellite assist. On 20 residential projects a month, the manual time adds up.
Per-quote pricing
Pricing scales with deal volume in ways that surprise growing teams. The flat per-seat model SurgePV offers is more predictable.

Verdict
SurgePV gives Indian EPCs the engineering depth Arka360 lacks, plus the satellite AI roof, plus a global code library for cross-border work, while preserving the PM Surya Ghar workflow Indian installers depend on.
₹ math. On 30 residential proposals a month, AI 3D roof saves roughly 30 minutes per design vs manual modelling. That is 15 hours a month reclaimed per designer, ₹7,500/month at a ₹500/hour blended rate.
