Digital solar surveying PWA — built for UK solar installation surveyors.
App Solar is a digital surveying platform built for the UK solar installation industry. A Progressive Web App that replaces the paper-forms-and-handwritten-notes workflow with a single tool solar surveyors use on iPads, tablets, and phones during site visits. WHAT IT DOES Solar surveyors use it to complete an entire property survey digitally, on-site. Address verification, exact location via what3words, roof inspection and measurement, battery location assessment, photo capture linked directly to the survey record, and integration with the Google Solar API for site assessment. Everything a professional solar surveyor needs during a site visit, in one tool. WHY IT MATTERS The traditional surveying process involves paper forms, photos shared through WhatsApp, handwritten notes, and duplicate data entry back at the office. App Solar replaces all of that with a digital workflow. Surveyors complete the survey once, on-site. Office teams get complete digital records immediately. Installations move forward without waiting for paperwork. WHY IT'S FOR SALE Owner is selling to focus on a proper rebuild with different architecture. Current version is fully functional for its core workflow — the sale gives someone a working starting point without the 6-12 months of dev time it took to build. WHAT'S INCLUDED Working PWA on appsolar.co.uk domain Full source code and deployment infrastructure Google Solar API integration Digital survey forms with photo capture Handover support from owner FUTURE ROADMAP Owner's original vision included offline-first architecture with automatic sync. This is a natural extension for a buyer to build, especially valuable given surveyors often work in areas with poor mobile coverage. WHO SHOULD BUY THIS Solar installation companies wanting a proven tool for their own surveying teams. Independent SaaS founders wanting a working starting point in the UK renewables space. Small dev shops or agencies serving UK solar wanting a portfolio product. The core workflow is validated by real solar industry expertise. What it needs is an operator with distribution or a builder with time to properly extend it.
Next step: <p>Three straightforward paths to revenue:</p><p><br></p><p>1. Solar installation companies wanting an internal surveying tool for their team. Sell it as a per-seat or per-team subscription (£20-50/user/month). Companies currently piecing together paper forms, WhatsApp photo sharing, and generic survey apps will pay for a purpose-built alternative.</p><p><br></p><p>2. Independent solar surveyors and small teams paying per-survey (£5-10 per completed survey). Higher-margin model for buyers who prefer usage-based pricing over subscriptions.</p><p><br></p><p>3. White-label licensing to larger renewable energy contractors who want branded surveying tools without building their own. £2-5K per company for annual licenses.</p><p><br></p><p>Beyond activating revenue, the natural extensions are: offline-first architecture (owner's original vision — completing this makes the tool genuinely field-ready for areas with poor signal), integration with major solar CRM systems (Aurora, OpenSolar, SolarEdge Designer), and expansion beyond UK to other English-speaking solar markets (Australia, Ireland, Canada).</p><p><br></p><p>The addressable market for UK solar surveying alone runs into thousands of installation companies, with the broader English-speaking solar market being 10-15x larger. The tool is built. What it needs is a buyer with distribution, sales capacity, or the time to build both.</p>
