What is the best ARKA360 alternative?
It depends on your need. If you want a design alternative, the best design tools are SurgePV, Aurora, OpenSolar and Solargraf. If your real need is to run the whole solar business — and keep a design tool you connect — SuryaHub is the best all-in-one. Below is the honest list, with the about, features, pros and cons of each.
Choosing an ARKA360 alternative.
ARKA360 is a design and proposal tool. So first decide: do you want a different design tool, or a platform to run the business with design connected? Check these four things.
Design tool, or whole business
Do you need a design replacement, or a platform to run the business with design connected?
Built for India
PM Surya Ghar, DISCOM, net-metering, GST and Hindi — built in, not bolted on.
The AMC moat
Does it keep 25-year service revenue with auto-scheduled visits and renewal reminders?
A pricing model that fits
Monthly SaaS or a one-time licence you own — and a clear INR price, not a per-seat surprise.
