Win and deliver more commercial solar projects
Commercial solar projects involve complex energy assessments, multi-stakeholder approvals and careful project management. Zigaflow gives commercial solar businesses the operational structure to grow confidently.
Project management and procurement for commercial solar businesses
Commercial solar projects are larger, more complex and involve more decision-makers than residential installations. The sales cycle is longer, the technical requirements are more demanding and the delivery risk is higher.
- UK commercial solar installers typically employ 10-80 staff, handling 5-30 rooftop or ground-mount projects simultaneously.
- Projects range from £20,000 SME rooftop installs to £500,000+ warehouse or industrial ground-mount systems.
- Installers juggle subcontractors, DNO applications, MCS certification paperwork, and scaffolding coordination across multiple live sites.
- Quoting is complex, involving panel specifications, inverter sizing, structural surveys, and ROI payback calculations for each client.
- Poor job costing and delayed invoicing after grid connection sign-off are common causes of cash flow problems.

More about Zigaflow for Commercial Solar Installers
Zigaflow gives commercial solar businesses the project management, procurement and financial tracking tools to handle this complexity profitably.
The problems we solve
Long sales cycles need careful pipeline management
Commercial solar decisions take months and involve energy managers, finance directors and often planning authorities.
Zigaflow pipeline management tracks every commercial opportunity through the full sales cycle, with stage-by-stage visibility and follow-up prompts.
Procurement of large equipment orders is high risk
A commercial solar project might involve thousands of panels and dozens of inverters.
Zigaflow purchase orders for large equipment orders are linked to the project specification. Every item is ordered to spec, checked against delivery and tracked to installation.
Planning and DNO approval delays create programme risk
Commercial solar installations depend on planning permission and DNO approval, both of which can take months.
Zigaflow milestone-based project management tracks approval stages alongside procurement and installation milestones. Nothing gets ordered before it should.
