Frequently asked
Everything teams ask before moving from legacy tools.
Both platforms include 3D solar design, but Solar Ladder goes far beyond it. You get a full CRM, project management, GST-compliant invoicing, a unified RMS dashboard, and a dedicated O&M module — all from one platform instead of piecing together multiple tools.
None at all. Solar Ladder has no caps on the number of projects, kW capacity, or proposals you can create. As your business scales, your costs don't spike just because you're doing more work.
The RMS (Remote Monitoring System) dashboard lets you track the generation output of every plant you've installed — all from a single screen. You can spot underperforming sites, share reports with clients, and stay on top of your entire installed base without switching between tools.
Yes — Solar Ladder includes a dedicated solar O&M module for managing service tickets, AMC schedules, and maintenance history across your installed base. Arka 360 has no equivalent feature, which means you'd need a separate tool just for post-installation support.
Completely. Solar Ladder supports unlimited proposal customisation — you can change colours, layouts, sections, branding, and content to match your company's identity and each customer's needs. There are no locked templates.
Most teams are fully onboarded within a week. Solar Ladder's support team provides guided, hands-on setup to get your data, templates, and workflows in place quickly.
