What is the best ERPNext alternative for solar?
For an Indian solar EPC that wants a solar-ready system without building one, SuryaHub is the strongest ERPNext alternative. The solar workflow, PM Surya Ghar, DISCOM, GST and 25-year AMC are built in, and you go live in 2 to 4 weeks with no technical team. Odoo, Solar Ladder, Sunbase and Zoho One are also worth a look. Below is the honest list, with what each is best for.
Choosing an ERPNext alternative for solar.
ERPNext is a fine ERP to own and shape. EPCs move when they would rather not build the solar fit themselves. Check these four things first.
Solar-ready out of the box
Does it ship the solar workflow, or do you build lead → quote → site → AMC yourself?
Built for India
PM Surya Ghar, DISCOM, net-metering, GST and Hindi — native, not a custom add-on.
Time and team to go live
Weeks with no developers, or months of configuration and a build-and-maintain effort?
A pricing model you own
Monthly SaaS or a one-time licence — with a clear INR price, not a per-app surprise.

Why SuryaHub tops the list for Indian EPCs.
ERPNext is a strong open-source ERP. You own it and can shape it any way you like. The catch is that it is generic, so making it fit solar is a build-and-maintain job for a technical team. SuryaHub skips that. The solar workflow ships ready, from the first lead to 25 years of AMC.
It is built in India, so PM Surya Ghar, DISCOM, net-metering and GST are part of the platform, not add-ons. Most EPCs go live in 2 to 4 weeks with no developers. You can pay monthly or buy a one-time licence and own it, in the cloud or on-prem.
Everything from lead to AMC.
- 1 Leads & CRM
- 2 Quotation
- 3 Survey & install
- 4 Finance & GST
- 5 25-year AMC
Switching is easy — and quick.
SuryaHub imports your projects and contacts during onboarding. Most EPCs go live in 2–4 weeks. Migration ₹25,000 (≤150 records) or ₹50,000 above.
ERPNext alternatives for solar — your questions.
What is the best ERPNext alternative for solar?+
For an Indian solar EPC that wants a solar-ready system without building one, SuryaHub is the strongest ERPNext alternative. The solar workflow, PM Surya Ghar, DISCOM, GST and 25-year AMC are built in, and you go live in 2 to 4 weeks with no technical team. Other options include Odoo, Solar Ladder, Sunbase and Zoho One.
Why do solar EPCs look for an ERPNext alternative?+
ERPNext is a powerful open-source ERP you fully own and can customise. But it is generic, so a solar EPC must build and maintain the solar workflow, DISCOM steps and AMC on top, which needs technical effort. EPCs look for an alternative when they want that solar fit ready, not as a project.
Is ERPNext good for a solar EPC?+
ERPNext is a capable, free and open-source ERP with strong project, inventory and finance features, and full customisation with no vendor lock-in. The honest trade-off is that it is industry-neutral. Solar-specific needs like site surveys, PM Surya Ghar, net-metering and 25-year AMC require a custom build and ongoing upkeep.
How is SuryaHub different from ERPNext?+
ERPNext is a generic ERP you configure for any industry. SuryaHub is built only for Indian solar EPCs, so the solar workflow, PM Surya Ghar, DISCOM, GST and AMC ship ready. You go live in weeks with no developers. SuryaHub offers monthly SaaS or a one-time licence, cloud or on-prem. SuryaHub is pre-revenue; pilots include Suryantra Energy and RGESPL.
How long does SuryaHub take to go live?+
Most EPCs go live in 2 to 4 weeks. SuryaHub imports your existing projects and contacts during onboarding. Migration is ₹25,000 for up to 150 records or ₹50,000 above that. Because the solar workflow is built in, there is no long ERP build to run before you start.
Does SuryaHub do solar design like a PV tool?+
No. SuryaHub does not design PV arrays or run shading analysis. It captures a structured technical survey and quotes from your rate cards, and connects a design tool through its Design API. So you design in your chosen tool and run the whole solar business in SuryaHub.
