Arka 360 is a solar design and proposal tool with CRM sold as an add-on, while RAYVO puts 3D design, CRM and ERP in one product at a lower yearly price. Which suits you depends on whether you need design alone or the whole business in one place. RAYVO publishes this comparison, so check every point with both vendors.
What Arka 360 offers
Arka 360 is a cloud tool for site modelling, shading analysis, component selection, a bill of materials and sales proposals. Its higher plans add SLD export, optimiser design, manual stringing and 3D model export for SketchUp and PVsyst. Its pricing page lists CRM as an add-on.
What RAYVO offers
- 3D design of flat, gable, shed and hip roofs of any outline, with tanks, trees and neighbouring buildings on the model.
- Shading checked for every module across the 21st of every month in half-hour steps, with the loss by month.
- Wind speed from IS 875, strings from the module datasheet, a priced bill of materials, subsidy and a 25-year payback in a proposal PDF.
- A full solar CRM and ERP on the same record: leads, surveys, quotations, projects, stock, serial numbers, invoices and payroll.
- Runs in a phone browser, so you can design on the roof.

When Arka 360 may suit you better
If you need SLD export, optimiser design, or a model to take into SketchUp or PVsyst, check those in Arka 360's Premium plan. RAYVO does not claim those today.
When RAYVO suits you better
If you want the design to flow into the quotation, the project, the stock and the invoice without retyping, and you want CRM and ERP included rather than added on, RAYVO does that in one product and at a lower yearly price.
How to decide
Model the same awkward roof in both: an L-shaped terrace with a tank and a taller neighbour. Compare the shading by month, the bill of materials and the proposal, then compare the total yearly cost for your team.
