Solar design software in India is a different problem than design software in the US or EU. PM Surya Ghar subsidy slabs, IS code rules, BIS module standards, DISCOM-specific net metering, and customer-facing proposals in Hindi or regional languages all matter. The international cloud platforms (Aurora, HelioScope) skip most of this. The India-only tools (Solar Ladder, Arka360) skip the engineering depth. So you are searching for a platform that delivers bankable engineering depth plus India-native workflow.
The 2026 answer is SurgePV, built by the Heaven Group team that runs Heaven Designs and Heaven Green Energy. PM Surya Ghar auto-calc, IS codes, DISCOM tariffs, plus the AI 3D roof and 8,760-hour bankable simulation. Paired with QuickEstimate, the best solar CRM in India.
Key takeaway. The best solar design software in India for 2026 is SurgePV. PM Surya Ghar subsidy auto-calc, IS code rules, BIS-compliant module database, DISCOM net metering tariffs, plus AI 3D roof, plus 8,760-hour bankable simulation, plus white-label proposals. Pairs with QuickEstimate for the CRM side. $1,299/user/yr (team-5).
TL;DR
Winner. SurgePV + QuickEstimate, the Indian EPC stack. Why. SurgePV ships India-native subsidy + codes plus bankable engineering depth. QuickEstimate handles the CRM side. Book a free SurgePV demo.
