Proposal cash flow and financing
Proposals now show the monthly bill without and with solar, a loan against the saving, and the client’s cash position over 25 years, with the same figures in the viewer and the PDF.

The Week Ahead, Delivered
The forecast no longer waits for you to open the app. Once a week, your own roof's numbers arrive by email, by browser notification, or both — at an hour learned from when you are actually around.
Monthly bills and smart-meter import
Self-consumption can use twelve monthly bill figures or a smart-meter export instead of a typical household profile.
Weekly forecast email
Every week, the coming seven days for your own roof: how the week stands against the seasonal normal, a bar for each day, the best day and the weakest, the best window for the washing machine or the car, and up to four things worth doing. Subscribers see their own saved layout; everyone else a reference rooftop at the same place. Clicking it opens the viewer on your project with the forecast already up.
Browser notifications
One notification a week instead of an email, or alongside it, with the week's verdict and the best day. Works on desktop and Android; on Chrome it carries a picture of the week. On iPhone and iPad, add SunTrace3D to your Home Screen first — Safari only delivers notifications to an installed app.
Sent when you are around, and it stops if you stop reading
Not a fixed Monday morning for everyone. The send time is learned from when you use the app and open mail, in your own time zone, and never lands in the middle of the night. Ignore four in a row and it drops to monthly; ignore seven and it pauses until you come back on your own. Opening one, clicking one, or simply returning resets it.
Yearly billing, 20% off
Personal and Professional can now be paid once a year at 20% less than twelve monthly payments: 86.40 EUR instead of 108, 950.40 instead of 1,188. Pick Yearly on the pricing page, or switch an existing monthly plan from your account page with one click; the unused part of the current month is credited and the next renewal is in 12 months.
Pause instead of cancelling
Not using it for a while? The cancel dialog now offers a 1 to 3 month pause. Your plan, projects and price stay as they are, nothing is charged while paused, and billing restarts on its own. You keep your paid features to the end of the period you have already paid for.
Hourly output follows your roof direction
The hour-by-hour production in the Energy System dashboard, the self-consumption figures and the battery sizing now use each panel's real orientation. A west-facing roof peaks in the late afternoon, an east-facing one in the morning; before this every roof peaked at noon, which sized batteries against the wrong hours.

From Scan to Signature
The whole chain in one place — team workspaces, branded proposals, electronic signature and the German tariff, tax and grid rules — alongside live site planning for land and development.
Export the 3D scene
Download the whole scene as one GLB or OBJ file — terrain, buildings, every solar panel, ground mounts, placed objects and imported models, exactly as positioned in the viewer — and carry on in Blender, SketchUp, Rhino or your CAD tool. Business and Enterprise.
Weather Forecast
See what your system will actually produce this week, not what an average year says. The real hourly forecast for your location runs through the same shading model as your annual yield, with cloud, cell heating, soiling between rain, snow cover and inverter clipping on top. Every day is measured against the 22-year seasonal normal for that exact spot, so "18% below normal" means something. Alerts flag snow on the array, multi-day slumps and free rain cleaning; advice tells you the best window for the washing machine or the EV.
Forecast emails
When the week ahead is well above or well below normal for your saved system, we tell you — instead of waiting for you to open the viewer. Paid plans get it led by a 3D render of their own roof with their own panels on it, plus the weakest day and the best window to shift heavy loads into.
German tariffs, tax and grid rules
A German site now gets a Tariffs & Compliance panel: the feed-in tariff for the commissioning date with its capacity bands, VAT under §12(3) UStG applied automatically, a VDE-AR-N 4105 grid pre-check, and the Marktstammdatenregister sheet filled from the design. Every figure carries its source, its date, and a warning when it is old — and your own rates override ours.
Tenant electricity (Mieterstrom)
Sell a rooftop system to a block of flats. Enter the dwelling units and the local basic supply tariff, and the panel prices the tenant supply at the §42a EnWG cap of 90% — tenant saving and landlord revenue side by side, and a plain warning when the scheme does not pay.
From scanned roof to signed deal
Open a prospect from the CRM straight into the viewer as a real design, seeded with the numbers the territory scan already measured. Send the proposal and the prospect moves to quoted with the total as its deal value; a signature moves it to won. The dashboard now reports what actually closed, next to what a territory might be worth.
Reviews that end in a decision
Your client approves or asks for changes on the 3D model, and approving takes them straight to signing the proposal. A new inbox shows every comment still waiting on you.
Branded proposals
Send clients a page instead of an attachment: your logo, your colours, the system, the price and the savings — readable on a phone and signable on the spot.
Electronic signature
Clients accept by signing on the page. Both of you get the signed PDF with a certificate recording who signed, when, and a fingerprint of the exact document.
Team workspaces
Your company owns its work, not one account. Invite up to five colleagues on Professional, share designs across the team, and see whose design is whose.
Your brand on client documents
Upload your logo and set your colours once. Everything you send a client is rendered in them — with a contrast check so the text stays readable.
Site Planning
Draw a parcel, set setbacks and choose what to build — the site yield, parking, cost and zoning check update as you work. Business and Enterprise.
Six building typologies
Double-loaded bars, podium, garden walk-up, wrap, industrial big box and data centre, each with its own rules and figures.
Parking and circulation
Surface, deck and below-grade parking, plus drives that enter from the street, reserve their ground and report any bay they cannot reach.
Zoning checker and district presets
Check a scheme against zoning rules in one step with generic district presets. Rules report; they never change the design.
Automatic setback labels
Parcel edges are classified front, side or rear from the real streets around the site, with a separate setback for each.
DXF, SVG and CSV export
Take the plan into CAD on named layers, into documents as SVG, and the quantity takeoff into a spreadsheet.

Undo & Redo
Every action — panel placement, object moves, rotations, deletions — can now be undone with Ctrl+Z and redone with Ctrl+Y. Batch operations like wizard placements undo in a single step.
Multi-Select & Copy/Paste
Shift+click to select multiple panels or scene objects at once. Copy with Ctrl+C, paste with Ctrl+V, or delete the entire selection with the Delete key.
