🇩🇪⚡ German Solar & Energy Leads — Marktstammdatenregister (MaStR) Scraper

Scrape Germany's official Marktstammdatenregister (MaStR) — the Bundesnetzagentur's public register of every power installation in Germany: 6.2 million+ solar PV systems (Photovoltaik / Solaranlagen) plus wind, biomass, hydro and storage.

Get the Betreiber (operator), location, capacity (kW), commissioning date and status for each installation — the exact lead data the German energy industry buys.

Free. Official open data (DL-DE-BY-2.0). No API key, no proxy, never blocked.

Keywords: Marktstammdatenregister, MaStR, Photovoltaik, PV-Anlagen, Solaranlage, Solaranlagen Daten, Betreiber, Balkonkraftwerk, Batteriespeicher / Stromspeicher, Windkraft, EEG-Anlagen, Bundesnetzagentur, German solar leads, PV operator data, solar installation database Germany, energy data export.

🎯 Who buys this (Germany = Europe's #1 solar & battery market)

Buyer	Use
🔋 Battery-storage (Batteriespeicher) sellers	Find solar homes with no battery yet → retrofit leads
☀️ Solar installers (PV-Installateure)	Competitor installs + area-by-area new projects
🔧 O&M / maintenance (Wartung)	Ageing systems needing service contracts
🔌 Heat-pump / EV-charger sellers	Solar households = ideal upsell customers
💰 Investors, insurers, manufacturers	Market intelligence & asset data

⚙️ Filters (input)

Field	Description
Energy type	☀️ Solar PV (default, 6.2M+), 💨 Wind, 🌿 Biomass, 💧 Hydro
Bundesland	Any of the 16 federal states, or all Germany
Postcode (PLZ)	e.g. 80 = Munich, 10 = Berlin, 20 = Hamburg
Min / Max capacity (kW)	e.g. max 30 = home rooftops (battery leads); min 100 = commercial
Commissioned after	fresh leads from a date, e.g. 2024-01-01
Companies only	named, contactable B2B operators (private persons are anonymised)
Operational only	only systems currently In Betrieb

📤 Output (per installation, clean — no nulls)

• mastr_number, unit_name, energy_type, status
• operator_name, operator_mastr_number, operator_type (company vs private)
• city, postcode
• capacity_kw_gross, capacity_kw_net, solar_modules
• commissioned_date, registered_date, last_updated
• profile_url (the official MaStR page)
• lead_score, lead_grade (UTILITY / COMMERCIAL / LARGE-ROOF / HOME+ / SMALL-HOME), lead_tags (named_operator, battery_retrofit_candidate, operational)

Lead angle

Private rooftop solar without a battery → tagged battery_retrofit_candidate. Commercial/named operators → tagged named_operator (directly contactable B2B lead). Bigger capacity = higher lead_score.

Note on operator names (GDPR)

Operators that are private individuals are anonymised by the register (shown as "natürliche Person") — that's the law. Companies, farms and organisations appear with their real name — turn on Companies only to keep just those contactable B2B leads.
