You know the problem

Enquiries without essentials

"How much for solar?" emails without roof area, consumption, or location. 80% of calls end without contract.

KfW funding maze

KfW 270, EEG feed-in, BAFA heating — clients do not know what combines. You manually educate each lead.

Solar industry FAQ

Is the KfW/EEG calculation really current?
The template uses KfW-270 conditions (interest, repayment subsidy) and EEG-2023 feed-in tariff as defaults. You can adjust the calculated fields when conditions change. Values are dated.
Can the client upload a roof sketch?
Yes — file upload up to 25 MB per file. PDF, JPG, PNG. Mobile users can shoot directly from browser. All uploads ClamAV-scanned.
How do I integrate this on my website?
Three ways: 1) iframe (copy code, paste), 2) Web Component (script tag for modern browsers), 3) Custom domain (subdomain like pv.your-firm.de). Custom domain is Pro feature.
Am I not competing with Heyflow/Perspective?
Heyflow and Perspective build mobile funnels with similar patterns. Difference: Questee offers live calculator fields as first-class (no custom code needed), AI funnel generation in minutes, and pricing is a fraction (€9 vs. €49-99/month).
How many leads per month does it handle?
Free: 250 responses/month. Pro: 10,000 responses/month. With typical solar conversion (3-5% form completion) this means 5,000-15,000 page views/month in free, 200,000+ in Pro.
What GDPR requirements should I observe?
Yes — address + consumption are personal data. We provide an automatic privacy checkbox + link to your privacy policy. DPA per GDPR Art. 28 on request. Hosting in Germany.
