Ground-mounted solar plants
Transform land into a technically defensible project.
A ground-mounted solar plant is designed around land ownership, planning rules, environmental constraints, access and available grid capacity.

AYM ENERGIE study
What we check before recommending a solution.
Installable capacity is never the only criterion. The site, its use, the grid, local constraints and project economics must remain consistent.
Land compatibility
Plots, easements, access, neighborhood, existing uses and actual availability of land.
Relief and implantation
Topography, slope, orientation, spacing, earthworks and equipment footprint.
Environment
Zoning, biodiversity, landscape, water, risks, heritage and possible additional studies.
Grid connection
Delivery point, distance to the grid, voltage level, substation and potential costs.
Operation
Internal roads, fences, security, maintenance, vegetation management and reversibility.
Project economics
Power, energy yield, losses, CAPEX, connection, operation and valuation scenarios.
Regulations & procedures
Rules to know before submitting the project.
Most ground installations require planning permission. The type of authorization depends in particular on the power, height and location in a protected area.
This information is general. The PLU, the protected sectors, the network manager and the characteristics of the site may modify the applicable procedures.
- Less than 3 kWp and height ≤ 1.80 mIn general, the installation can be exempted from formalities, outside protected areas.
- Less than 3 kWp and height > 1.80 mA prior declaration of works is required in general.
- From 3 kWp to less than 3,000 kWpA prior declaration of works is required in general.
- From 3,000 kWpA building permit is generally required.
- Protected sectorsThe thresholds are stricter: a prior declaration may be necessary below 3 kWp and a building permit from 3 kWp.
- Additional proceduresDepending on the site, environmental, agricultural, landscape or connection studies may be added to the urban planning authorization.
Recommended route
Transform an idea into a documented decision.
Qualify the land
Identify ownership, access, PLU and main constraints.
Pre-size
Define a preliminary footprint, capacity and technical assumptions.
Assess the risks
Examine environment, connections, easements, topography and acceptability.
Consolidate the file
Produce the layout, production, economy and technical parts.
Decide to continue
Arbitrate based on residual risks, schedule and project value.

Frequently asked questions
The first answers to frame the project.
No. The urban planning threshold does not replace other procedures which may apply depending on the land, the environment, the heritage or the nature of the project.
Yes for an initial feasibility, but the connection strategy must be studied early because it can significantly modify the power and the economy.
AYM ENERGIE frames needs and integrates their conclusions. Specialized ecological, geotechnical or hydraulic expertise can be entrusted to partner offices.
