SolarDraft — sometimes typed as Solar Draft — and Arka360 both help solar companies design rooftop systems in 3D and send proposals. The difference is mostly in who they're built for: SolarDraft is built around Indian EPCs and the PM Surya Ghar subsidy, while Arka360's published feature set leans toward the US and global commercial solar market, with AI-driven layout optimization and financing tools built around loans, PPAs and leases.

"Choose based on your market: Indian subsidy-driven residential sales favour SolarDraft; US-style financed commercial deals favour Arka360's toolset."
If you're an Indian EPC that needs subsidy-ready proposals, a built-in CRM and transparent INR pricing, SolarDraft is built for exactly that. If you're selling in a market where financing structures like PPAs and leases are central to the pitch, Arka360's published feature set may be a closer fit.
