About This Solution

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.

Zigaflow gives commercial solar businesses the project management, procurement and financial tracking tools to handle this complexity profitably.

Key Facts
  • 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.
How It Works

Up and running in four simple steps

1

Enquiry Capture and Qualification

Leads arrive via website forms, referrals, energy brokers, or direct outreach to facilities managers and finance directors. Each enquiry is logged with site address, roof or land type, estimated kWp requirement, and decision-maker contact details.

2

Survey, Design, and Proposal

Following a site survey, a detailed proposal is built covering system design, panel and inverter specifications, projected generation output, payback period, and total installed cost. The branded proposal and any supporting structural or shading reports are sent to the client for approval.

3

Project Scheduling and Site Delivery

Once a contract is signed, the project is broken into stages covering DNO application, equipment procurement, scaffolding, installation, inverter commissioning, and MCS sign-off. Tasks, subcontractors, and materials are tracked against the project timeline and agreed budget.

4

Invoicing, Payment, and Sync

Stage payment invoices are raised at agreed milestones such as deposit, equipment delivery, installation completion, and grid connection. Payments are tracked against each project and transaction data is synced to accounting software to keep margins and cash flow visible.

The problems we solve

Built specifically for your industry - Zigaflow tackles the operational headaches that generic software ignores.

Long sales cycles need careful pipeline management

Commercial solar decisions take months and involve energy managers, finance directors and often planning authorities. Without a clear pipeline view, opportunities go cold and forecasting is unreliable.

How Zigaflow helps
