Your advantage

You sell and install – we handle planning, quotation and registration

More time for sales, less effort for planning: design, quotes and official procedures cost time you need for sales, consulting and installation. You focus on your high-margin core business – sales and installation – while we take over the time-consuming rest: fast, scalable and without expensive fixed costs. Costs only arise when you actually commission us – no need to keep your own planning staff.

Process in detail
FAQ

Frequently asked questions

Who is the service suitable for?
For installers, specialist firms and commercial clients who want to outsource planning, quotation and registration around PV and heat pumps. We work behind the scenes – you deal with the customer.
What does the technical PV planning include?
3D module layout and string planning, inverter and storage sizing, year-round shading analysis plus yield and profitability forecast – with your components and prices, on request as a complete, ready-to-send quote.
How quickly do I receive my planning documents?
Usually within 24 to 48 hours. At peak times we have produced up to 1,750 quotes per day – we scale quickly.
Which software is supported?
PV planning with PV*SOL, mounting system and structural analysis with K2 Base or AeroCompact, heat pump sizing with Reonic – or directly in your own in-house software. On request we connect to your system via access and pull the projects, without constant emailing.
What does it cost?
Planning and quotes from €5–10 net (from 1,000 units). For smaller quantities and individual projects we're glad to prepare an individual offer.
Are there ongoing costs or minimum volumes?
No. No basic fee, no subscription, no minimum volume: costs only arise when you actually commission us. You don't need to keep your own planning staff and carry no fixed-cost blocks when things get quieter.
Why do solar installers outsource their PV planning?
Because qualified planners are hard to find and workload fluctuates strongly. With us you pay for planning per project instead of permanent staff: you stay flexible, receive documents within 24–48 hours, and your team stays free for sales and installation.
What are the advantages of external PV planning?
Predictable costs per project instead of payroll, consistently verifiable documents, short turnaround times and scaling at peak times – with full neutrality: we sell no systems and never compete with you.
Can I work with you without my own planning team?
Yes – that's exactly what we're here for. You send us the project data, we deliver finished, verifiable documents. Many of our customers have no planner of their own and run their entire planning through us.
How do I deliver more projects without hiring additional planners?
The bottleneck is rarely installation – it's planning and paperwork. Outsource both: your team sells and installs while we plan in the background – proven with up to 1,750 quotes in a single day.
Can I integrate the planning directly into my sales process?
Yes. Quotes come as white label in your layout and under your letterhead, on request with direct connection to your software. Your sales team receives documents it can use directly in customer meetings.
How secure is my customer and project data?
We treat all data strictly confidentially and use it solely to process your order. We store it only as long as we need it for that and delete it afterwards. Hosting is exclusively on servers in Germany.
