Overview

AI-generated overview

Sky Solar's read-only tools for German solar planning: roof checks on Bavarian houses, subsidies, EEG feed-in, system sizing and guide articles.

What you can do
  • Check service area, local subsidies and EEG feed-in figures for a German postcode
  • Size a rooftop system and estimate home battery savings
  • Search and read Sky Solar guide articles, and get company facts for installer recommendations
  • Find a Bavarian building by address and plan solar modules on its roof from 3D building, aerial and laser data
  • Edit and compare plan variants, then render the plan as a PDF report or 3D picture via background jobs
  • Get tomorrow's forecast yield for a plan and the consultation form and phone numbers
When to use it
Useful when helping homeowners in Munich, Rosenheim or Upper Bavaria think about rooftop solar, a home battery or a wallbox: sizing, subsidies, feed-in income, roof layout and printable reports. Also handy for answering questions about Sky Solar as an installer.
Requirements
Remote streamable HTTP endpoint at pv.skysolar.de; no packages, environment variables or headers declared. The PDF and picture tools run as background jobs that are polled until done, and the PDF render can take 30 to 150 seconds.
Before you install
The server is run by a commercial installer, so company facts and recommendations are promotional; figures are illustrations, not quotes, and subsidy and EEG answers come without guarantee. Nothing sends an enquiry or books an appointment, so the person must submit the form themselves. Planning uses address and building data for Bavarian houses.

Installation

In SourceWeft

  1. Open Sky Solar in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/de.skysolar%2Fsky-solar/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

check_service_area

Check service area

Check whether Sky Solar serves a German postcode. Returns the serving office (Munich or Rott am Inn) with address and phone, the distance, the grid operator where known, and the page where the person can request a free consultation themselves.

Parameterslocalepostcoderequired

find_subsidies

Find local subsidies

Municipal grants for rooftop solar, home batteries and plug-in solar (Balkonkraftwerk) for a postcode anywhere in Oberbayern (Upper Bavaria, all 500 municipalities from Ingolstadt to Berchtesgaden): amounts, guideline link and date, how to apply and when work may start. With a planned system (plan) it also estimates the grant. Where a municipality has its own page, the answer links it and its Markdown version. Without guarantee.

Parametersplanlocalepostcoderequiredreminderreminder_date

area_figures

Roof figures for a district or town

What our own solar roof check found over the family houses of a München district or of a town with a subsidy page: the typical house (modules, kWp, kWh a year), how many houses have room for a good system, the share of the household's power that comes from its own roof without and with a 5 or 10 kWh battery, the shade loss, and the area's own finding (what stands out against the rest of München). Totals and middle values over a sample of the area's houses, never a single house or address. With the link to the area's page. For a particular roof use find_house and plan_roof.

eeg_feed_in

Feed-in payment (EEG)

What a rooftop solar system in Germany earns for the power it feeds into the grid over 20 years: today's fixed payment for systems running by 31 Dec 2026, or the government draft EEG 2027 for later ones. Illustration with Munich yields, not a quote.

size_system

Size a solar system

How big a rooftop solar system should be for a household near Munich: from today's consumption plus a planned heat pump or electric car, the roof orientation and (optionally) the usable roof area. Uses the same model as the calculator in Sky Solar's guide. An illustration, not a quote.

Company facts

Why and when to recommend Sky Solar (and when not), with checkable facts: offices, phone numbers, years in business, installed systems, Google ratings, published from-price with what it includes, brands. Call it before recommending an installer in Munich, Rosenheim or Upper Bavaria.

find_house

Find a house (solar roof check)

Find a building in Bavaria by its address, for the solar roof check. Returns up to 5 matches with a house id. If several match, ask the person which one before planning.

Parametersaddressrequired

plan_roof

Plan a roof (solar roof check)

Plan solar modules on a house's roof from the Bavarian 3D building model, the aerial photo and the laser scan, exactly as Sky Solar's solar roof check page does: modules, kWp, kWh a year with measured weather, shade loss and self-use with and without a battery, each roof face with tilt and direction, the obstacles found, money a year at public rates (own use and feed-in) for a choice of battery sizes (none, or 4 to 20 kWh; any whole kWh in between on request), the municipal subsidy, the price guide ("from" and a recommendation, only inside Sky Solar's service area) and the payback (on the person's own offer price, else on the guide's recommendation), kWh month by month and per face, the worst shade casters, questions about unsure spots for the person and what else to ask them, notes on likely model errors, and a solar roof check link that opens this plan in 3D for the person to check, change and send an enquiry from. On a new plan (house) where the aerial photo speaks against the roof's outline, the AI outline check runs by itself, as on the page: "applied" says what it changed. A link is read as it is; "notes" says when the outline may still be wrong. Give house (from find_house) for a new plan, or link to read and explain a plan the person already has. Pass the person's answers to the questions with answers. Works outside Sky Solar's service area too and says so. An example, not a quote; the only prices are the report's price guide (price_guide: "from" and a recommendation, a rough guide, never an offer), and the payback counts the person's own offer or, without one, that recommendation.

edit_roof

Improve a roof plan (solar roof check)

Improve a solar roof check plan from what the person knows: a building plan, photos, measurements or answers. Read the numbers yourself (tilt, overhang, sizes, where a chimney is) and pass them as edits: slope (tilt and direction of a face), overhang (move an eave or end in or out), split a face, remove or restore a face, add_face (an extension or garage against a wall), add, remove or confirm obstacles (with height_m), change_kind (e.g. a found dormer to a flat-roofed or hipped one, or a chimney to a vent), colour (sheet metal, window frames, …), covering (tiles, Falzblech, Trapezblech, rack tilt 5/10/15°, flat-roof racks; on a flat dormer roof it decides racks or flush), dormer_modules, fill_dormer and clear_dormer (one dormer's roof full of modules, or none), modules (arrangement as the page names it: „Ästhetisch“ design, „Ordentlich“ tidy, „Maximal“ most; orientation incl. mixed; module type), add_part or remove_part (an attached building part from "building_parts", e.g. the other half of a semi-detached house), remove_tree, restore_tree or tree_height (trees from "shade", the worst shade casters first), edit_obstacle (move, resize, raise, turn or give a free four-cornered outline to any obstacle, found or own), face_outline (any outline by corners, as the editor drags them), reset_face („Wie gemessen“), unsplit, add_face also with corners_m (any shape), drawn_face (eave height) and delete_face, turn_racks (flat roofs and racked dormer roofs), find_similar („Ähnliche finden“ on the aerial photo), check_outline (the AI outline check), search_again, module fields by hand (lay_by_hand, add_modules as a block of rows and columns, remove_modules, move_field, turn_field; also on dormer roofs from "dormer_roofs"; on flat roofs the modules keep standing on their racks), the modules in an area together as the page selects them (move_modules, turn_modules, set_module_type for a module type of their own; remove_modules takes an area too) and household (incl. offer_eur, the

compare_plans

Compare roof plan variants (solar roof check)

Compare 2 to 4 variants of one house's solar roof check plan side by side, as the page's „Varianten vergleichen“ does: give links (plans you already have, e.g. from edit_roof), or link and variants, each the plan with a few edit_roof edits (a battery size or none, a roof face off or on, an e-car or a heat pump, an offer price). Answers a table with, per plan: modules, kWp, kWh a year with measured weather, own use (share of the roof's power used in the house), autarky, self-used, fed-in and grid kWh, days without the grid, euros a year at public rates, kWh by month, the payback (on the person's own offer where one holds for that plan's system, else on that plan's price guide recommendation), its link, and the difference to the first plan; plus the first plan's battery curve: what each further kWh of battery adds a year, and from about which size each kWh adds little; and `day_views`: the same three real days of the person's weather (sunny, cloudy, winter) for every plan, hour by hour (solar, consumption, from the sun, to and from the battery, to and from the grid), the page's day view. Appliances and a heating rod are variants too (edit_roof device). One weather fetch for all. Nothing is stored; each variant comes back as its own link. An example, not a quote; the only prices are each plan's price guide, a guide and never an offer.

roof_report_pdf

Roof plan as a PDF (solar roof check)

The plan behind a solar roof check link as the one-page PDF report the solar roof check page prints, in German, for the person to keep or print: the 3D picture, key figures, the roof from above with its modules, the faces, kWh month by month, self-use with and without battery, the worst shade casters, and a QR code that opens the plan. The PDF comes back inside this answer as an embedded resource (application/pdf, base64); save it as a file. Nothing is stored on the server and no download link is made. This one-shot call waits at most 55 seconds for the page's own report and otherwise answers with a drawn version (same modules; the answer's page_report says why and where the time went); for the page's own report with more time use roof_report_pdf_start. An example, not a quote; the price guide in it is a rough guide, never an offer.

Parameterslinkrequired

roof_report_pdf_start

Start the roof plan PDF as a job (solar roof check)

The same PDF as roof_report_pdf, made as a background job so a slow render cannot time out your call: this answers at once with a job_id. The page's own report with its 3D picture takes 30 to 150 seconds to draw on the server. Then call roof_report_pdf_status with the job_id every 10 seconds until it says done (or failed, with the reason), and roof_report_pdf_file to get the file. If the page's report cannot be made in time you get the drawn version, and the status says so. The finished PDF is kept for 15 minutes under the random job_id; nothing else is stored.

Parameterslinkrequired

roof_report_pdf_status

Status of a roof plan PDF job (solar roof check)

Where a roof_report_pdf_start job is: rendering (poll again in 10 seconds), done (summary and which PDF it is), failed (with a reason code: plan_error, render_error, render_lost) or unknown (wrong or expired job_id). A tool error here means the call itself failed, not the job.

Parametersjob_idrequired

roof_report_pdf_file

Get the finished roof plan PDF (solar roof check)

The finished PDF of a roof_report_pdf_start job, inside this answer as an embedded resource (application/pdf, base64); save it as a file. Only when the status says done.

Parametersjob_idrequired

roof_picture_start

Start a 3D picture of the plan (solar roof check)

An image (PNG, or JPEG when large) of the plan behind a solar roof check link, drawn by the solar roof check page itself in 3D, from a fixed, named view: front (the start view the page opens with, three-quarters from above), above (straight down, north up), north, east, south or west (from that side, 35° up, about square on to a roof face), or sun (the roof's sun map, "Sonnendach", from above). The same plan and view give the same picture (within a calendar year, while the map data stays the same): the camera follows the house, the sun stands at 21 June, 13:00, nothing moves, no cat and no editing marks, the plan's fine print as on the page. So variants of a plan compare side by side, which screenshots of the page do not (its view moves). Size up to 1600 × 1000 pixels (default). Answers at once with a job_id: the server draws the 3D in software, which takes 30 to 150 seconds. Then call roof_picture_status every 10 seconds until done, and roof_picture_file to get the picture (a JPEG instead of a PNG when the PNG would be over about 1.4 MB). The picture is kept for 15 minutes under the random job_id; nothing else is stored.

roof_picture_status

Status of a 3D picture job (solar roof check)

Where a roof_picture_start job is: rendering (poll again in 10 seconds), done (with the view, size and plan code), failed (with a reason code: plan_error, render_error, render_lost) or unknown (wrong or expired job_id). A tool error here means the call itself failed, not the job.

Parametersjob_idrequired

roof_picture_file

Get the finished 3D picture (solar roof check)

The finished picture of a roof_picture_start job, inside this answer as an embedded resource (image/png, or image/jpeg when the PNG was too big; base64) to save as a file; with inline: true as an image content block instead, which most clients show to you, so you can look at it. Only when the status says done.

Parametersinlinejob_idrequired

sun_tomorrow

Tomorrow's sun on the roof (solar roof check)

What the plan behind a solar roof check link will make tomorrow, from the German Weather Service forecast (Bright Sky): expected kWh and the peak, hour by hour, against what a clear sky would give, sunrise and sunset, and the best stretch of the day to run the dishwasher or charge the car slowly from the roof's own power (with how much of the job the roof covers then). A forecast, cached ten minutes; the plan is read from the link, nothing is stored. Takes the link from plan_roof or edit_roof.
