Ground-Mounted Solar Parks in Germany

Ground-mounted photovoltaic (PV) systems are the fastest-growing renewable energy segment in Germany. The federal government targets 215 GW total PV capacity by 2030, roughly half of which is expected from ground-mounted installations. In 2025, the Bundesnetzagentur auctioned 9,900 MW of ground-mounted solar capacity — a record volume.

Permitting Pathways

Ground-mounted solar in Germany follows a different permitting route than wind turbines. No BImSchG permit is required — instead, the process runs through municipal building law:

• § 35 BauGB privileged status — since the Solarpaket I (2024), ground-mounted PV up to 80 MWp is privileged in outdoor areas within a 200 m corridor along motorways and railways. No local development plan (Bebauungsplan) required in this corridor.
• Bebauungsplan (B-Plan) — for sites outside the corridor, the municipality must adopt a dedicated development plan. Timeline: 6–18 months, depending on political will and environmental complexity.
• Building permit — required in both cases. Issued by the Bauordnungsamt. Cost: EUR 5,000–20,000.

EEG Auctions

Most ground-mounted solar parks above 1 MWp participate in the EEG auction system run by the Bundesnetzagentur. Key parameters (2025/2026):

Projects below 1 MWp receive fixed EEG feed-in tariffs without auction. Agri-PV systems below 1 MWp receive a premium rate of 9.36 ct/kWh.

Land Lease for Landowners

Ground-mounted solar offers attractive lease income for agricultural landowners:

• Lease rates: EUR 2,500–5,000 per hectare per year (southern Germany and prime sites at the upper end)
• Lease duration: 20–40 years (matching EEG remuneration + extension)
• Land requirement: approximately 1.0–1.2 hectares per MWp
• Key contract clauses: decommissioning guarantee, indexation clause, sublease rights, early termination compensation

For comparison: arable land lease in Germany averages EUR 350–600/ha/yr, making solar lease 5–10x more attractive per hectare.

Agri-PV (Dual-Use Agriculture + Solar)

Agri-PV combines crop production or livestock grazing with elevated or spaced-out solar modules. Germany classifies these as "special solar installations" under EEG 2024, with a premium tariff:

• Below 1 MWp: 9.36 ct/kWh (no auction required)
• Above 1 MWp: auction with separate segment, higher ceiling
• DIN SPEC 91434: defines categories (elevated, vertical bifacial, inter-row) and minimum agricultural yield requirements (at least 66% of reference yield)

Grid Connection — The Most Common Bottleneck

Grid connection is the single biggest project risk for ground-mounted solar in Germany:

• Pre-inquiry to the grid operator (Netzbetreiber) is mandatory before building permit application. Response time: 8 weeks (legally), often 3–6 months in practice.
• Voltage levels: parks up to ~10 MWp connect to medium voltage (20 kV); larger parks require high voltage (110 kV) or a dedicated substation.
• Cost: EUR 50,000–500,000 depending on distance to the nearest substation and required grid reinforcement.
• Curtailment risk: in congested grid areas (northern Germany), the grid operator may curtail feed-in under § 14 EEG. Compensation is paid, but reduces revenue certainty.

Species Protection in Solar Parks

Ground-mounted solar parks require species protection assessment, though typically less complex than wind projects. Key survey targets:

• Ground-nesting birds (skylark, lapwing) — avoidance measures: construction outside breeding season (March–August), habitat strips between module rows
• Reptiles (sand lizard, smooth snake) — relocation protocol if found on site
• Insects and pollinators — biodiversity-friendly parks with wildflower meadows between rows increasingly required by municipalities

Cost for species protection assessment: EUR 5,000–20,000 (significantly less than wind, which requires full-season bird surveys).

Technology: Modules and Trackers

In Germany's moderate irradiance climate (950–1,200 kWh/m²/yr), trackers are increasingly common for parks above 20 MWp but not universal. The economic case depends on the gap between CAPEX increase and yield uplift at the specific site.

Co-Location: Solar + BESS

Adding battery storage to a solar park is becoming standard practice. The shared grid connection reduces CAPEX by EUR 0.5–2 M, and the battery captures midday price dips by time-shifting feed-in to evening peak hours. See our Battery Storage page for details on BESS permitting and economics.
