Custom software for solar EPC and installation companies
Solar EPC software connects the full project flow, from lead and site survey to proposal, approval, procurement, installation, commissioning and maintenance, so nothing falls between sales, engineering and field teams. ImliStack builds it around your process and the tools you already use.
Start with a conversation: we discuss your requirements and recommend an approach before you commit to anything.
The problem
Where Solar EPC businesses lose time
Slow proposals
Site survey data is retyped into proposal templates by hand.
Scattered documents
Customer KYC, approvals, net-metering and subsidy paperwork lives in folders and chats.
Installation coordination
Crews, materials and dates are juggled over the phone.
After-sales gaps
Warranty and maintenance visits are not tracked.
What we build
Software designed around your workflow
Not a ready-made product: we design and build the modules you need, then extend them in phases.
Solar CRM
Leads, follow-ups and pipeline by source, location and system size.
Site survey app
Roof measurements, photos, shading notes and electrical details captured on a phone.
Proposal generation
Branded proposals with system size, production estimate and pricing.
Installation scheduling
Crews, materials and milestones per project.
Document & commissioning
Customer documents, approval status and commissioning checklists.
Maintenance & warranty
Service tickets, preventive maintenance and warranty records.

Works with your existing systems
- Solar design and production estimate tools
- Accounting software
- WhatsApp, SMS and email
- Monitoring platforms where APIs are available
How we implement it
- Discovery We map your current workflow, documents and systems, and agree the first problem worth solving.
- First release A focused version that replaces the most painful spreadsheet or paper process, live in weeks.
- Integrate Connect accounting, ERP, devices or messaging where their interfaces allow.
- Extend Add stages, reports and teams in phases, based on how people actually use it.
Business outcomes
What changes when the workflow is in one system
- Every lead followed up and tracked to a sale
- Proposals generated from survey data, not retyped
- Documents and approvals in one place per customer
- Installation crews, materials and dates coordinated in one system
Typical goals for this kind of system; actual results depend on your process and are agreed during discovery.

FAQ
Solar EPC software: common questions
Can ImliStack build custom software for solar EPC companies?
Yes. ImliStack develops software for site surveys, customer proposals, installation planning, document workflows, field-team coordination and operational reporting. The scope is set in a discovery phase around your process and existing tools.
Can a site survey feed straight into the proposal?
Yes. When the survey app captures roof dimensions, orientation, shading and load details as structured data, the proposal can be generated from it instead of being retyped.
Does it replace our design or monitoring software?
No. Custom EPC software usually connects to those tools, pulling design outputs or monitoring data where they offer exports or APIs.
Is this different from software for solar panel manufacturers?
Yes. EPC and installation companies manage projects, customers and field crews; manufacturers manage production batches, serial numbers and quality. They need different systems.
