Solar farms
We design and build ground-mounted solar farms: the structure, panel installation, electrical works and the medium-voltage grid connection. We can install 5 MW in the first month and, from the second month, 10 MW per month, once the work site has been handed over and the materials have been delivered.
- ✓5 MW installed in the first month, then 10 MW per month
- ✓ANRE-certified for medium-voltage design and installation (C1A and C2A certificates)
- ✓We also install with client-supplied materials on solar farms above 5 MW
Renewable energy through solar farms
Solar farms provide large-scale renewable electricity. Nectaria offers complete PV supply and installation services, including the design and implementation of solar farms.
Our solar farm expertise
Our solar energy specialists coordinate design and implementation, assessing the layout, equipment and site conditions to support generation while considering environmental requirements.
ANRE-certified for medium-voltage design and installation (C1A and C2A certificates), we also build the farm's grid connection: medium-voltage lines and transformer substations.
Why choose us for your solar farm?
We coordinate the technical stages of development and provide support through implementation and operation. The solution is designed for your site's requirements and constraints, with responsibilities agreed in the project contract.
Benefits of solar farms
Solar panels convert sunlight into electricity, reducing reliance on fossil fuels.
Sunlight has no fuel cost. Solar farms still require monitoring, maintenance and other operating expenditure, which must be included in the project assessment.
A solar farm's financial performance depends on generation, electricity prices, connection costs, operating costs and the project's financing. Returns are not guaranteed.
Solar farms can be considered for different types of land, including some sites unsuitable for other uses, subject to feasibility and approvals.
Solar farms can create jobs and support the local economy.
Solar farm development can support renewable energy goals. Each investment requires a project-specific technical and financial assessment.
Clear steps, from consultation to maintenance
Our solar farm process covers these stages:
Initial consultation
We establish our customers' needs and objectives.
Tailored design
Each solar farm is designed for its site and generation objectives.
Professional installation
Our installation team includes certified professionals.
Monitoring and maintenance
We provide after-sales services to support solar farm operation and performance.
Advice on correctly installing a PV system
Our on-site consultation helps you choose a suitable PV solution for your property, with the information you need to make a considered decision.
1. How it works
- ✓First contact: call or email us and describe the project and land.
- ✓Initial review: a consultant reviews site information, grid connection and investment objectives.
- ✓Site visit: our consultants assess the site and recommend an appropriate PV installation approach.
2. What to prepare
The address, available area, land documents and connection information help establish the project's starting assumptions.
3. Next step
After the initial review, we confirm what further information is needed and whether a site assessment is required.
You receive a recommendation based on the site's actual conditions and limits.
Technical and contractual stages are explained before a quotation is issued.
Talk to a consultant →The structure is calculated for your land
We work with quality ground-mount structures from established manufacturers. The manufacturer sizes the structure specifically for the client's site — wind, snow and soil — so every solar farm gets a customised structure, not a standard kit.
Where the price of a cheap structure comes from
There are many cheap ground-mount structures on the market. Some manufacturers cut the price through:
- thinner steel and fewer tonnes of steel per MW;
- fewer bracings, so the structure is more flexible;
- cheaper zinc coating, with weaker corrosion protection;
- shorter piles, with weaker anchoring in the ground.
The difference does not show at delivery but in operation: an undersized structure can deform and bend under snow.
What to compare between quotes
- ✓Tonnes of steel per MW: compare them for the same panels and the same list of components: piles, beams, rails, bracings and connections.
- ✓Structural calculation: ask for the calculation for your site, with the wind and snow loads and the pile depth.
- ✓Tilt angle: 25° can be an optimal, low-cost choice in southern Romania, but not necessarily in Transylvania, where there is more snow and it slides off less easily from panels with a shallow tilt.
The panels, inverters, batteries and other equipment we work with, with datasheets and warranty conditions, are listed in the full range on the Equipment page.

Structures, cables and connectors
- Galvanised steel ground structures, made in Poland or Romania
- 6 mm² solar cable for DC runs
- Original Stäubli MC4 connectors
- Protection panels with components from established brands
What we need for a quote
With this information we send you a quote for the structure, including panel installation.
- 1Geotechnical study — determines the pile type and depth for your land.
- 2Site plan of the land — shows the shape, area and access to the land.
- 3Address or coordinates of the land — for the wind and snow loads of the site.
- 4Technical grid-connection approval (ATR), if you have it — for the approved capacity and the connection point.
We also install with client-supplied materials on solar farms above 5 MW.
Send us the documents you have and we will agree together on anything else needed for the quote.
An example for a 1 MW ground-mounted system
Each project is quoted individually to reflect its complexity and scope. The following is the existing illustrative 1 MW ground-mounted example; current equipment prices, VAT and final scope are confirmed in the quotation.
- 1AIKO 670 W or 780 W solar panels (or similar, depending on the project) — N-type. 30-year performance warranty; product warranty according to the certificate for the model offered.
- 2Huawei inverter — warranty according to the certificate of the quoted commercial model.
- 3Huawei smart meter
- 4Premium ground mounting structure — warranty of at least 12 years.
- 5Cables and connectors — Premium Lapp cable specification in this example; final connector selection confirmed in the design.
- 6Premium protection boards
- 7Installation — included.
- 8Transport — included.
Illustrative turnkey system total: ≈ EUR 495,800 excluding VAT (≈ EUR 496/kW), plus 21% VAT
*The example excludes design, grid connection, fencing and video surveillance, which are quoted separately. It is not a current binding quotation.
How long does it take?
We can install 5 MW in the first month and, from the second month, 10 MW per month, once the work site has been handed over and the materials have been delivered. The exact schedule is set in the contract, for the land and configuration of the project.
What is the process?
- 1Initial phone consultation.
- 2The customer sends photographs, land information and the project address.
- 3We send the quotation.
- 4Quotation acceptance.
- 5Site visit and discussion with the customer.
- 6Contract signing and first advance invoice for 50%.
- 7Delivery of the main equipment — panels, inverter and batteries — and second advance invoice for 40% of the total contract value.
- 8PV system installation.
- 9Prosumer documentation submission, followed by the file registration number being sent to the customer.
- 10Payment of the final 10% of the contract value.
- 11The distribution operator installs a new meter if needed, then issues the prosumer approval.
