Arka360 Alternative 2026: 6 Tools Compared

If you are looking for an Arka360 alternative in 2026, you are most likely an installer or EPC who values Arka360’s AI-led residential workflow but needs deeper bankable simulation, multi-country support, or an integrated proposal stack. This guide compares six realistic solar design software options and explains why we recommend SurgePV for most teams.

Why Installers Look for an Arka360 Alternative

Bankable simulation depth

Arka360’s simulation works for residential, but module-level 8,760-hour shading and P50, P75, P90 outputs accepted by lenders are not the headline. SurgePV ships the PV simulation and bankable yield report on every paid plan.

Multi-country coverage

Arka360 has strong roots in India and is expanding. SurgePV ships NEC, IEC, AS/NZS, IS code libraries and country-specific tariffs (PM Surya Ghar, SREC, FiT, Einspeisevergütung) out of the box, with proposals in 9 languages.

Integrated proposal stack

SurgePV’s branded solar proposal builder ships on every paid plan, with e-signature and interactive web links. The proposal is produced from the same project as the design, so the numbers cannot drift.

About This Comparison

Pricing, features and product positioning described here were checked in July 2026 using publicly available vendor information. Vendors change pricing, packaging and capabilities without notice, and several do not publish prices at all. Treat every figure as a starting point for your own enquiry rather than a quotation, and confirm current terms directly with each vendor before making a purchasing decision.

All product names, logos and trademarks are the property of their respective owners. Reference to them here is for identification and comparison only and does not imply any affiliation with, sponsorship by, or endorsement from those companies. SurgePV is a Qbits Energy product, so treat this as a vendor comparison written by an interested party and weigh it alongside independent sources and your own trial of the tools.
