Solar Project Management Software Development

Single dashboard showing all active solar projects with milestone status, schedule risk flags, and financial summary at a glance. The project lifecycle stages covered span the full EPC sequence: prospecting, site assessment, design, permitting, procurement, installation, commissioning, and ongoing O&M. Each project card in the portfolio view shows current stage, days since last milestone completion, budget variance percentage, and a RAG status indicator -- red for projects with overdue milestones or a budget overrun exceeding a configurable threshold, amber for projects approaching a risk condition, green for projects tracking normally.

Filter controls narrow the portfolio by project type (residential, commercial, utility-scale), geographic region, client, and project manager. Drill-down from the portfolio summary to the project-level Gantt and financial detail happens in a single click without switching systems or opening a separate spreadsheet. The portfolio manager can see across 20, 50, or 200 concurrent projects and identify which ones need intervention this week, which are on track, and which are approaching a stage gate that requires resource attention. PTO (Permission to Operate) tracking status is visible at portfolio level so the operations team can see how many projects are post-commissioning, awaiting grid operator sign-off versus already generating revenue.

Project templates for residential, commercial, and utility-scale solar builds with the standard milestone set pre-configured: site assessment, design review, AHJ (Authority Having Jurisdiction) permit submission, permit approval, utility interconnection application, procurement and equipment delivery, installation, electrical inspection, utility interconnection sign-off, commissioning, and PTO (Permission to Operate). Each milestone is a structured gate with required documents, sign-off requirements, and downstream dependencies that the system enforces. A commissioning milestone cannot be marked complete without the commissioning checklist being signed off, and the checklist includes a PVsyst predicted vs. actual performance comparison -- the system validates that the measured yield at commissioning falls within an acceptable range of the PVsyst modelled output.

Task-level scheduling within each milestone captures individual work items with assignees, start dates, due dates, and predecessor relationships. Task dependencies prevent a task from being scheduled before its predecessors are complete. Subcontractor task assignment notifies the relevant trade when their tasks are ready and due. Design tool integration with HelioScope API or PVsyst can pull system design parameters (module count, inverter configuration, predicted annual yield) directly into the project record at the design milestone, eliminating manual re-entry of design data into the PM system. CAD drawing attachment at the design milestone links the AutoCAD layout files to the project record version-controlled. Automated schedule risk alerts fire when tasks become overdue or when a milestone predecessor is delayed by more than a configurable threshold, giving the project manager advance warning rather than discovering a slip after the milestone date has passed.

Project budget setup by cost category mirrors the typical solar EPC cost structure: modules, inverters, racking and mounting hardware, balance-of-system electrical, labour (installation crew, electricians), subcontract packages (civil, roofing, structural), interconnection fees, permitting and engineering fees, and contingency. BOM (bill of materials) management links the equipment list -- module model and quantity, inverter model and count, racking system specification -- directly to the procurement budget line so the cost of the designed system is always tied to its components. Purchase order automation generates draft POs from the approved BOM, reducing the manual step of transferring equipment lists from the design tool to the procurement system.

Actual cost is entered against budget lines as invoices are received and approved. Committed cost tracking captures signed purchase orders and subcontract agreements that are not yet invoiced, so the forecast-to-complete is based on total committed spend rather than just actual invoiced costs. Actual-vs-budget variance is displayed at line item level and total project level, updated in real time as costs are posted. Milestone billing tracks the draw schedule for contracts where client payments are triggered by project stage completion -- the system generates a billing event when a milestone is signed off, and the client invoice can be raised directly from the milestone record. Procore and BuilderTREND are the reference platforms in the construction PM space; our solar project management software addresses the same financial tracking problem with solar-specific milestone structures, equipment BOM integration, and PTO tracking that generic construction PM tools do not provide.

Subcontractor contact records capture trade type (civil, structural, electrical, roofing), insurance certificate expiry date with automated renewal alerts, licence number and jurisdiction, and performance history from previous projects. Resource allocation assigns subcontractors to specific project phases with scheduled start and end dates, and the scheduling view surfaces conflicts where the same subcontractor is booked across overlapping projects in the same period -- a common problem for EPCs managing more than ten concurrent builds in the same region.

Task assignment to subcontractors includes due dates, priority, and document attachments -- the specific drawing revision, specification section, and scope document that applies to their work package. Subcontractor portal access is role-scoped: each trade sees their assigned tasks, the current revision of drawings and specs relevant to their scope, and a communication thread for their work package. They cannot see contract values, other subcontractors' tasks, client contact details, or project cost data. Task completion is confirmed in the portal with a completion photo upload, and the project manager's confirmation step is required before the task is marked closed in the project plan. Subcontractor performance is tracked across projects by task completion rate, on-time delivery rate, and defect rate (number of defect items raised against their work package relative to scope), producing a performance history that informs subcontractor selection on future projects.

Central document store for each project covers the full document set a solar EPC generates and receives: site assessment reports, PVsyst and HelioScope design files, AutoCAD layout drawings, structural engineering reports, electrical single-line diagrams, AHJ permit applications and approval notices, utility interconnection applications and signed agreements, equipment datasheets, procurement contracts, subcontract agreements, inspection reports, commissioning certificates, and compliance documentation. Version control marks the current revision of every document clearly and archives previous revisions with the date of supersession and the reason for revision, so anyone looking for the current drawing cannot accidentally retrieve an outdated revision that was circulated by email.

Drawing transmittal workflows formalise the process of issuing updated design documents to subcontractors. A transmittal record captures which documents were issued, to which recipients, at which revision, and on which date. Recipients acknowledge receipt in the subcontractor portal, and the acknowledgement timestamp is recorded against the transmittal. Permit and interconnection application tracking records the submission date, application reference number, assigned reviewer, and expected decision date for AHJ permits and utility interconnection applications -- the two external dependencies that most frequently drive schedule delays on solar projects. Automated expiry alerts fire before time-limited documents lapse: AHJ permit validity periods, equipment warranty registrations, subcontractor insurance certificates, and PTO conditional approval timeframes all carry configurable alert windows so the project manager is notified before an expiry creates a compliance problem.

Monthly progress reports generated automatically from live project data -- construction progress against programme (Gantt comparison), cost against budget by category, committed-cost forecast to complete, risk register summary with open items and their mitigation status, and upcoming milestone dates for the next 30 and 60 days. Report format is configurable per investor or lender so the output matches the reporting schedule and field set required by each financing agreement. A construction lender drawing schedule typically requires different data points from an equity investor's monthly progress report; both templates run from the same underlying project data without duplication.

Commissioning reporting includes the PVsyst predicted vs. actual performance comparison -- the measured DC output and AC yield from the commissioning test data compared against the PVsyst model for the same irradiance conditions. This comparison is a standard deliverable in utility-scale financing agreements and is often required by the lender's independent engineer before the final construction loan draw is approved. PTO tracking status is reported per project showing the current interconnection stage, the date PTO was requested from the utility, and the expected PTO approval date. Investor portal access provides read-only views of progress reports, financial summaries, and the project document store so capital partners can review the information they need without requesting it from the project team. Custom report templates for different investor or lender requirements are configured during the onboarding phase and regenerated automatically each reporting period from live data.
