Quick answer
What permits does a solar farm need in Poland?
Installed solar capacity in Poland reached 24.8 GW at the end of 2025. A ground-mounted solar farm needs no environmental decision up to 1 ha of built-up area (0.5 ha in or near protected areas), a local zoning plan above 1 MW or on the best farmland, a building permit above 150 kW and, once built, only a notification of completion – no occupancy permit.
Above 1 MW the operator needs a generation licence from the President of URE; from 50 kW to 1 MW an entry in the MIOZE register is enough. Rooftop installations skip the environmental decision and the zoning change altogether.
The statutory deadlines are short – up to 120 days for connection conditions, 65 days for the building permit, 14 days for an objection to the notification of completion – but each runs from a complete application, which can be filed only once the earlier steps are in place. In practice the schedule of a ground-mounted farm is set by three questions asked at the very start: is there grid capacity at the connection point, does the land class force a local zoning plan, and has the municipality adopted a general plan that keeps a WZ decision available.
Connection conditions issued from 30 April 2026 are valid for only 12 months, so the land, zoning and permit work has to be planned around the date the connection agreement must be signed. Solar farms have no occupancy permit stage, which shortens the end of the process compared with wind farms and biogas plants.

The path for a solar farm in Poland in seven stages
A solar farm follows the same path as any renewable project, with thresholds of its own at almost every stage. The full path is set out in our legal guide to renewable energy investments in Poland.
A SOLAR FARM IN POLAND · SEVEN STAGES
1
Site and land rights
Check solar radiation, shading, slope, ground stability and the soil class, then secure ownership or a long-term lease that keeps the installation the investor’s property. How to draft such a lease and secure the cable route is explained in our guide to site selection and land rights for renewable projects.
2
Environmental decision
Not needed up to 1.0 ha of built-up area, or 0.5 ha in or near protected areas, and never for rooftop or facade PV; above that, a KIP and screening. How the procedure runs and when the authority demands a full report is covered in the environmental decision for renewable energy projects.
3
Zoning basis
A local zoning plan is mandatory above 1 MW, on class I–III or forest land, and above 150 kW on class IV land; otherwise a WZ decision may be enough where the municipality has a general plan. Which zoning route is open in a given municipality is set out in zoning for renewable energy projects in Poland.
4
Grid connection
Conditions within 120 days for grids above 1 kV (45 days for rooftop PV up to 2 MW), valid for 12 months; above 2 MW the operator prepares an expert assessment. Fees, the advance and a cost calculator are in our guide to grid connection for renewable energy projects.
5
Building permit
Needed only above 150 kW and issued within 65 days of a complete application; above 6.5 kW the design must be approved by a fire safety expert. The attachments to the application and the path for each technology are described in building permits for renewable energy projects in Poland.
6
Completion
A notification of completion: operation may start after 14 days unless the authority objects; no occupancy permit unless the building permit requires one. Which documents to attach and how to avoid an objection is explained in the section on the notification of completion.
7
Licence or register
Above 1 MW a generation licence from the President of URE; from 50 kW to 1 MW entry in the MIOZE register; up to 50 kW only a notice to the grid operator. The documents and timelines are listed in the licence and MIOZE section of our renewable energy guide.
Despite its apparent simplicity, the permitting of a photovoltaic project depends heavily on the system’s area, capacity, location and installation method.
To check which of these steps a specific project needs, use the permit checker in our renewable energy guide.
Which permits each type of solar installation needs
The type of installation decides which stages apply. The table shows the general rule; every rule has exceptions.
| Stage | Micro-installation up to 50 kW | Rooftop PV above 50 kW | Ground-mounted solar farm |
|---|---|---|---|
| Environmental decision | Not required | Not required, regardless of area | Not required up to 1.0 ha (0.5 ha in or near protected areas) |
| Zoning basis | As a rule no WZ decision | No separate land-use designation | Local plan above 1 MW, on class I–III or forest land, or above 150 kW on class IV land |
| Construction | No building permit or notification | Building permit only above 150 kW | Building permit above 150 kW |
| Completion | Fire service notice above 6.5 kW | Notification of completion | Notification of completion; no occupancy permit |
| Generation | Notice to the grid operator | MIOZE up to 1 MW; licence above 1 MW | MIOZE up to 1 MW; licence above 1 MW |
Ground-mounted solar farms in Poland
Utility-scale solar farms carry the heaviest permitting load, and two thresholds – the built-up area and the capacity – drive most of it.
- Site analysis. Beyond nature conservation, planning and title, a solar site needs solar radiation maps, a shading check against neighbouring structures, the slope for module exposure, ground stability and the soil class.
- Environmental decision. The built-up area is measured around the outermost modules, including roads and transformer stations. Above 1.0 ha – or 0.5 ha in or near national parks, nature reserves, landscape parks, Natura 2000 sites or their buffer zones – the project needs an environmental decision.
- Local zoning plan. A WZ decision is not enough for a farm above 1 MW, on class I–III or forest land, or above 150 kW on class IV land. Plants up to 1 MW on class V–VI soils and wasteland need no prior change of the municipality’s general planning documents.
- ZPI as the faster route. Where there is no plan, or the plan prohibits a solar farm, the investor can ask for an amendment or for an integrated investment plan (ZPI), which is simplified for renewables other than wind.
- WZ decision. On a new application filed from 1 September 2026, a WZ decision is available only where the municipality’s general plan is in force; WZ decisions issued from 2026 expire five years after becoming final.
- Grid and construction. The connection application lists the number and types of inverters and modules. Above 150 kW a building permit is needed, followed by a notification of completion.
For larger solar farms a standard WZ decision is not enough: the municipality must have adopted a local zoning plan – above 1 MW, on class I–III or forest land, and above 150 kW on class IV land.
Rooftop and commercial PV installations
Rooftop installations on industrial halls, warehouses, logistics centres and commercial buildings are one of the fastest-growing segments of the market, from just above 50 kW to well over 1 MW.
- No environmental decision and no zoning change. Rooftop and facade PV is exempt from the environmental decision regardless of its area, and an installation on an existing building generally needs no separate land-use designation.
- 150 kW threshold. Up to 150 kW there is no building permit and no notification; above it, a building permit under the general rules.
- Micro-installations up to 50 kW. No environmental decision, no building permit or notification, as a rule no WZ decision, and no licence or MIOZE entry. If the installation fits within the building’s connection capacity, the operator is only notified 30 days before commissioning.
- Fire safety. Above 6.5 kW the design must be approved by a fire safety expert, and the State Fire Service is notified of completion and of the intention to use the installation.
- Leased buildings. Where a tenant installs PV on a landlord’s roof, the lease or a separate agreement should deal with consent, the roof warranty, the lender’s covenants and removal at the end of the lease.
Agri-PV in Poland: solar panels on farmland
Agri-PV combines electricity generation with crops or grazing on the same land. Modules are usually mounted on elevated structures or vertically, leaving room for farm work; partial shade can reduce evaporation and heat stress on crops.
- No separate legal category. Polish energy law does not treat agri-PV as a separate technology, so the general rules for ground-mounted solar farms apply – including the environmental-decision area thresholds and the local-plan requirement on class I–III land.
- Land class is the main hurdle. Because agri-PV is meant for productive farmland, the local-plan requirement on the best soils and the protection of agricultural land decide whether a project can go ahead.
- Status in 2026. The Ministry of Climate and Environment has said it is analysing other EU countries’ rules but has not taken legislative decisions; projects in Poland are so far mainly pilots.
In practice: an agri-PV project should be planned as an ordinary solar farm for permitting purposes, with the farming use documented separately – the law does not yet reward it with simpler procedures.
Floating PV: solar farms on water
Floating PV sits on platforms anchored to the bottom or banks of post-mining pits, retention reservoirs, industrial ponds or lakes, using areas that cannot be built on.
- Water-law permit. Installing support structures in a water body and laying cables along its bottom requires a water-law permit from the State Water Management Authority (Wody Polskie), usually for no more than 30 years.
- Additional assessments. Depending on the location, the impact on the aquatic ecosystem and on the reservoir’s water management may need to be assessed separately.
Locating a solar installation on water brings additional obligations under water law – above all a water-law permit for the floating structures and the cables along the bottom of the reservoir.
Building-integrated photovoltaics (BIPV)
Building-integrated photovoltaics – glass facades, facade panels, solar louvres, PV roof tiles – replace part of the building materials while generating electricity.
- Same exemptions as rooftop PV. No environmental decision; up to 150 kW no building permit or notification.
- Construction-product rules. Because BIPV elements form part of the facade or roof, they must meet the technical requirements for construction products – structural safety, fire protection, thermal insulation and durability.
Generation licence or MIOZE register for solar farms
Selling electricity from a solar installation requires a licence or a register entry, depending on its installed capacity.
| Installed capacity | Regime | Authority |
|---|---|---|
| Up to 50 kW (micro-installation) | No licence and no register entry; notice to the grid operator | Distribution system operator |
| Above 50 kW up to 1 MW (small installation) | Entry in the MIOZE register | President of URE |
| Above 1 MW | Generation licence for 10 to 50 years | President of URE |
During technical commissioning, energy may be sold for up to 12 months before the licence is granted. The licence procedure is described in the licence section of our renewable energy guide.
Case study: rooftop solar on let and financed warehouses
One matter from our files. Client details are generalised.
CASE · ROOFTOP PV ON LET WAREHOUSES · 2026
Letting tenants install rooftop solar without putting the building or the bank loan at risk
In 2026 Dudkowiak & Putyra acted for a Swiss investor whose bank-financed production and service buildings in southern Poland are let to two international companies. Both tenants wanted rooftop PV, and one had already installed a system of about 50 kWp without consent. We drafted landlord agreements making each installation conditional on the financing bank’s consent, an independent technical sign-off and replacement roof warranties where the original contractor’s warranty would lapse, capped the capacity at 150 kW on one site and gave the landlord the right to require dismantling, backed by contractual penalties.
What it shows. Rooftop PV may be exempt from permits up to 150 kW, but on a let and financed building the real risks sit in the lease, the roof warranty and the loan covenants – and they have to be settled before the panels go up.

FAQ – solar farms in Poland
Does a solar farm in Poland need an environmental decision?
Not if its built-up area, measured around the outermost modules and including roads and transformer stations, does not exceed 1.0 ha, or 0.5 ha in or near protected areas; rooftop and facade installations never need one.
When does a solar farm in Poland need a local zoning plan?
Above 1 MW regardless of land class, on class I–III agricultural or forest land, and above 150 kW on class IV land; in these cases a WZ decision is not enough.
Does a solar farm need an occupancy permit?
As a rule no; after construction a notification of completion is enough, and operation may start after 14 days unless the authority objects or the building permit requires an occupancy permit.
Do I need a licence to sell electricity from a solar farm in Poland?
Above 1 MW yes, a generation licence from the President of URE; from 50 kW to 1 MW an entry in the MIOZE register is enough, and micro-installations up to 50 kW only notify the grid operator.
How long does it take to get grid connection conditions for a solar farm?
Up to 120 days for grids above 1 kV, or 45 days for rooftop PV up to 2 MW; the conditions are then valid for 12 months, and above 2 MW the operator also prepares an expert assessment of the impact on the power system.
Can a solar farm be built on agricultural land in Poland?
Yes, but on class I–III land a local zoning plan is always required and on class IV land above 150 kW; plants up to 1 MW on class V–VI land and wasteland need no prior change of the general planning documents.
Is agri-PV regulated separately in Poland?
No, agri-PV is not a separate legal category, so the general rules for ground-mounted solar farms apply; as of 2026 the Ministry of Climate and Environment has not taken legislative decisions on it.
What permits does a floating solar farm need?
In addition to the usual solar-farm permits, a water-law permit from Wody Polskie for the floating structures and the cables, usually for no more than 30 years, and possibly additional assessments of the impact on the water body.
What are the fire safety rules for solar installations in Poland?
Above 6.5 kW the design must be approved by a fire safety expert, and the State Fire Service is notified of completion and of the intention to use the installation.
Can a tenant install rooftop solar on a leased building?
Only with the landlord’s consent; the agreement should cover the roof warranty, the lender’s consent where the building is financed, capacity limits and removal at the end of the lease.
