What does a complete PV system cost?
A meaningful price covers a compatible, safe installation sized for your property. Configure the capacity, equipment and options for an updated estimate.
Cost breakdown
What you pay for in a turnkey system
Compare equivalent configurations and work. Check exact models, warranties, protection, services and support after commissioning.
The inverter
Capacity, number of phases, battery compatibility, backup functions, optimisation and warranty all matter.
Mounting structure and installation
Roof type, fixing quantities, access, work at height and ground mounting affect installation costs.
Protection and cable routes
Cables, DC and AC boards, protection, earthing and cable lengths must be calculated for the project.
Battery
Usable capacity, charging and discharging power, compatibility and backup functionality affect the investment.
Design and documentation
Assessment, design, configuration, testing and technical documentation turn individual products into a working system.
What an installation includes
What you usually get in a residential system
The list from Nectaria's residential offer. Exact models, warranties and any additional work are confirmed in the personalised quotation.
The system installed on tiled or metal roofing includes:
- 1Solar panels
- 2Inverter sized for the project (Hinen, Deye, Solis, Solplanet, Fronius, Huawei or Victron), with the warranty in Nectaria's offer for the selected model
- 3Smart meter
- 4Premium mounting structure for metal roofing — 10-year warranty under the applicable terms
- 5Premium 6 mm² solar DC cable, with final sizing determined for the project
- 6Original Stäubli MC4 connectors, in pairs with documented compatibility
- 7Protection panels with components from established brands, selected for the project
- 8Installation — included
- 9Transport — included
- 10Measurement of the existing earth electrode — included at no charge
- 11Prosumer documentation — included at no charge
Optional additions, quoted separately:
- Panel-level optimisers
- Hinen, Deye, Dyness, BYD, Huawei or Solplanet batteries, compatible with the selected inverter
- EV charging station
- Earth electrode if the existing installation does not meet applicable ANRE requirements
How payment works
In three instalments: 50% when the contract is signed, 40% when the main materials are handed over and 10% after the prosumer documentation is submitted.

Prices including VAT, checked in the store on 20.09.2026. Packages from 20,000 RON. Estimated standard installation: 1,500 RON. A new inverter, backup, additional cable runs and special work are quoted separately. Funding, stock and compatibility are checked individually.
3, 5 or 10 kW PV system prices
Capacity is just the first variable
We do not publish a fixed price that becomes inaccurate when equipment or VAT changes. The configurator estimates costs from the products and options selected.
3 kWModerate consumption
May suit an efficient home without large electrical loads. Requires space for panels and a correctly sized inverter.
What to check
Bills, daytime consumption, grid connection and usable space
5–6 kWHigher residential consumption
A capacity range often considered for households with electric water heating, air conditioning or electrification plans. A battery remains a separate option.
What to check
Annual consumption, phases, heat pump or electric car
8–10 kWFully electrified home
Requires sufficient space, grid connection capacity and consumption. The home's hourly demand profile is essential to estimate how much solar energy it will use directly.
What to check
Approved capacity, consumption profile, roof and grid connection
Comparing quotations
Look beyond the total at the bottom of the page
- 1Compare the exact panel model, output and quantity.
- 2Check the inverter, phases, warranty and battery compatibility.
- 3Ask for the protection, mounting and cable specifications.
- 4Confirm whether installation, testing, monitoring and documentation are included.
- 5Check who provides service and how warranties are handled.
- 6Ask which costs could arise after the site assessment.
FAQ
Solar panel pricing questions
What a realistic calculation includes and how to compare two quotations.
How is a PV system paid for?+
In three instalments: 50% when the contract is signed, 40% when the main materials are handed over and 10% after the prosumer documentation is submitted.
How much does a 5 kW PV system cost?+
Capacity alone is not enough to price a system properly. Panel model and quantity, inverter, connection, roof, mounting, protection, cable routes, installation and battery all matter. Nectaria Solar's configurator uses your chosen configuration to provide an updated estimate.
Is installation included in the system price?+
The quotation must clearly state what is included. A turnkey solution can cover mounting structures, panel installation, cable routes, protection, inverter, configuration and testing. Additional work arising from site conditions is identified during assessment.
Is a battery included in the solar panel price?+
A battery is usually optional and should be listed separately. Its price depends on capacity, power, technology, compatibility and the desired backup arrangement.
Why do quotations for the same capacity have different prices?+
The kW rating does not describe every component. Panel efficiency and warranties, inverter class, mounting, protection, cable quality, documentation, service and included work can all differ.
Is it cheaper to buy panels and installation separately?+
The initial price can sometimes appear lower, but compatibility, warranties, design, protection and responsibility for commissioning must be checked. Separate suppliers can complicate later service and claims.
Can I pay in instalments or through leasing?+
Financing options are available for certain customers and configurations. Terms are confirmed at quotation stage, subject to the available financial product and eligibility.
