Quote, install, commission, lodge STCs — solar workflow for sparkies
Solar PV installs touch four regulators (CEC, your DNSP, Clean Energy Regulator for STCs, state electrical inspectorate) plus the customer — and the windows are unforgiving. This pack collapses the whole workflow into one job: quote builder with panel and AS/NZS 4777-compliant inverter records, DNSP pre-approval application (per state, all 13 distributors), AS/NZS 4777 commissioning checklist (PV array test, string voltage, anti-islanding inverter check, RCD test), STC creation reminder timed against the Clean Energy Regulator's 12-month installation window, and a branded customer handover pack with manufacturer warranties, anti-shading layout, and the CER-compliant Solar Cert. Drop your CEC accreditation number once, it auto-prints on every cert and quote.

Commission on-site: tick the AS/NZS 4777 checklist, log readings
REC Registry reminder lands 11 months in so STCs don't lapse
Apps that work great with Solar Install Pack.
About OneBookPlus apps
OneBookPlus apps aren't external integrations stitched together with Zapier or n8n — they're native modules installed inside the same platform you already use for invoicing, bookings, CRM, and accounting. That means Solar Install Pack reads from and writes to the same customer records, financial entries, and calendar events as every other module, with no scheduled sync delays and no risk of data drift between systems.
Because the marketplace runs inside OneBookPlus, billing is consolidated. Solar Install Pack appears as a single line on the same OneBookPlus invoice as your plan, so you don't end up reconciling separate vendor charges across three or four different SaaS subscriptions. Cancellation is one click and never reaches into your data — uninstalling an app removes the feature from the UI but preserves the underlying customer, invoice, and booking records, so reinstalling later picks up exactly where you left off.
Every app in the marketplace is built specifically for the Australian small and medium business context: GST and ABN handling are first-class concerns, dates render as DD/MM/YYYY, currency defaults to AUD, and the underlying compliance plumbing (BAS summaries, ATO-friendly records, AHPRA / NDIS / Fair Work checkpoints where relevant) is shared across modules. New Zealand businesses are supported with NZ tax and timezone defaults using the same code paths.

$19/moThe pack auto-schedules a reminder 11 months after install (the CER deadline is 12 months) and generates the STC creation worksheet with panel count, inverter kW, postcode-driven STC quantity, and your CEC accreditation number. You still log into the REC Registry to lodge the STCs — no API integration yet — but the data is pre-calculated and ready to paste.
Yes. Each Australian DNSP (Ausgrid, Endeavour, Essential, Energex, Ergon, SA Power Networks, Western Power, PowerWater, Jemena, AusNet, CitiPower/Powercor, Evoenergy, TasNetworks) has its own connection-application form. The pack renders the per-DNSP form with installer accreditation, inverter model, AS/NZS 4777 compliance flag, and proposed export limit pre-filled.
PV array open-circuit voltage and string voltage measurements, polarity check, insulation resistance, anti-islanding inverter shutdown test (witnessed grid disconnect), RCD trip test (where applicable), monitoring portal sign-in test, and customer walkthrough of the inverter app. Each ticks off on the mobile checklist and prints on the handover pack.
Yes. The quote builder handles AC-coupled battery retrofits (Powerwall, Sungrow, Tesla, Sigenergy) on top of an existing or new PV install, including sub-board changes and backup-gateway costs. Treated as a single solar-install job, the cert covers PV inverter (AS/NZS 4777.2) and battery system (AS/NZS 5139) compliance — including the fire-separation, restricted-location and signage checks 5139 requires for the battery enclosure.
Drop your CEC accreditation number (Designer/Installer) once in settings and it auto-prints on every solar STC cert and quote. The customer-handover PDF also surfaces it so they can verify in the CER accreditation register before signing off.
