Paris Rooftop Solar: MVP Requirements for Coding Agent

July 4, 2026 · Prepared by Doc (AI research partner) · Complete Business Flow

🎯 The MVP's Single Job

Validate demand by automating the free audit experience — the first two touchpoints a syndic has with us.

Why this matters: If syndics won't sign up for a free, automated analysis of their building's solar potential, they certainly won't pay €1,200 for full‑service project management.

1. User Journey (What Syndics Experience)

1
Landing Page → Instant Sign‑up
Syndic enters name, professional email, and number of buildings they manage (dropdown: 1–10, 11–30, 31–100, 100+). No address collection yet.
2
Welcome Email (Immediate)
"Thanks for signing up. We're analyzing your buildings' solar potential using public data. You'll receive a personalized PDF report within 24 hours."
3
PDF Report Delivery (Within 24h)
Email with attached PDF: "Your Solar Potential Report" (contents detailed below).
4
Follow‑up Email (Day 2)
"How was the report? Want to take the next step? Schedule a 15‑minute discovery call to discuss generating AG documents and getting installer quotes."

2. What Actually Goes Into the PDF Report

📋
Executive Summary (Page 1)
"We analyzed your portfolio of [X] buildings. Here are the top opportunities for rooftop solar installation in Paris."
🏆
Top 3 Buildings by ROI (Page 1–2)
For each building:
  • Address: Example address in Paris (mock data for MVP)
  • Estimated annual savings: €6,500 – €12,000
  • Payback period: 5–7 years
  • Roof area: 180–250 m²
  • Solar potential: 28,000–35,000 kWh/year
  • Regulatory status: ABF required? PLU restrictions?
  • Enedis delay estimate: 6–9 months

📝
Regulatory Checklist (Page 4)
  • ABF (Architecte des Bâtiments de France): Required for historic zones
  • PLU (Plan Local d'Urbanisme): Height/color restrictions
  • Enedis connection: 6–9 month wait typical
  • Subsidies available: MaPrimeRénov', CEE
  • AG vote required: >⅔ majority
🚀
Next Steps (Page 5)
"Ready to move forward? We offer:
  1. AG‑document generation: Motion + explanatory note for copropriétaires
  2. Installer quotes: 3 comparable bids from vetted partners
  3. Project management: Handle ABF permits, Enedis paperwork, subsidies
Cost: €1,200 per building (everything included until installation)."

3. What Happens After the PDF

A
Syndic schedules discovery call (via Calendly link in Day 2 email)
B
15‑minute discovery call – Confirm which building(s) they want to proceed with, explain process, answer questions
C
If interested: Send invoice (€1,200 per building) via Stripe
D
Upon payment (manual steps for MVP):
  • Generate AG documents (Word templates)
  • Email 3 installer partners for quotes
  • Compile quotes into comparison PDF
  • Deliver complete package to syndic
E
If AG vote passes: Manual project management (ABF permits, Enedis paperwork, subsidy applications)

4. Technical Capabilities Required

📄 Lead Capture & Storage
Form that captures syndic info (name, email, building count) and stores it somewhere accessible (database, spreadsheet, Notion).
✉️ Email Automation
Send transactional emails: welcome (instant), report delivery (within 24h), follow‑up (Day 2). Professional templates, French language.
📊 PDF Report Generation
Create branded PDF with the structure above. For MVP, use mock data (example addresses, estimated savings). Template should allow dynamic insertion of syndic name and building count.
⏱️ Background Processing
Queue PDF generation jobs so reports are delivered within promised 24‑hour window, even during off‑hours.
📈 Basic Analytics
Track sign‑ups, email opens, PDF downloads, and discovery‑call scheduling to measure what's working.
🔗 Calendar Integration
Link to Calendly (or similar) in follow‑up email for discovery‑call scheduling.

5. What Stays Manual (For Now)

Key insight: The automated audit is the hook. Everything after can be manual while we validate demand.

🗺️
Real Geodata Integration
MVP uses mock building data. Once validated, integrate IGN API for actual cadastre analysis.
📝
AG‑Document Automation
Manual Word templates for first customers. Automate once we see consistent demand.
👷
Installer Quote Collection
Email installer partners manually, compile quotes.
📋
Project Management
Notion/Linear/Spreadsheets to track permits, paperwork, applications.

6. The Real Validation Questions

What This MVP Answers

  1. Will syndics sign up for a free solar audit? (Conversion rate from landing page)
  2. Will they open/read the PDF? (Email open rates, PDF download tracking)
  3. Will they schedule a discovery call? (Interest in paying €1,200)
  4. What questions/objections do they have? (Feedback from discovery calls)
  5. Will any actually pay? (Conversion from call to payment)

Everything else (scalable architecture, real geodata, installer integrations, regulatory automation) is premature optimization until we know syndics want this.

7. Success Metrics

10+ sign‑ups within 2 weeks of launching acquisition tests (€200 Google Ads + LinkedIn outreach)
50%+ open rate on the PDF delivery email
20%+ conversion from sign‑up to discovery‑call scheduling
1+ paying customer within first month

8. Next Steps

1
Build the MVP
Coding agent implements the capabilities above (lead capture, email automation, PDF generation, background processing).
2
Launch Acquisition Tests
Run €200 in Google Ads (targeting syndic pain‑point keywords) + LinkedIn outreach to property managers.
3
Measure for 2 Weeks
Do we get sign‑ups? Do any convert to calls? Gather feedback.
4
Decide: Pivot or Double‑Down
If validation fails, pivot to different wedge/customer. If it works, invest in automating next layer (AG documents, installer integrations).

🔧 Technical Implementation Note

The coding agent should choose whatever stack they're most productive with. The library used for PDF generation, the database, email service, or hosting platform are implementation details. What matters is delivering the user‑facing capabilities described above.
