HNordic provides site-specific quotations rather than published prices -- not every site is suitable for a wind turbine, and the variables that determine cost (foundation requirements, grid connection distance, planning complexity, electrical installation length) vary too much for a single figure to be meaningful.
As an indicative reference point: a 50 kW WindWhisperer system with integrated battery storage is priced from €225,000 excl. VAT and installation costs. The 100 kW platform scales up proportionally, and the installation element depends entirely on site conditions.
A site survey and formal quotation is the only reliable way to know your number.
Turbine and battery (40–50% of total)
The WindWhisperer 100 Max with 430 kWh LFP integrated battery is the most complete offering. The turbine itself includes rotor, nacelle, controller, and inverter. The battery is sealed lithium-ion with built-in management and monitoring. This is a complete system from wind collection to power conversion and storage.
Cost reflects manufacturing, certification, quality control, and international logistics. VAWTs are still less common than HAWTs, so volumes are lower and per-unit costs are higher than they will eventually be.
Installation labour and site prep (20–30% of total)
This includes foundation design and pouring (if needed), mast assembly, electrical installation, and commissioning. Some sites need existing concrete strengthening, ground levelling, or access road improvement. Coastal or remote sites may incur travel costs for the installation team.
A straightforward farm or commercial site install is at the lower end. A rooftop install or a site requiring foundation work is at the higher end.
Electrical and grid connection (10–20% of total)
DNO application fees are small (£50–£200 in the UK). The larger costs are the cable runs from turbine to battery/inverter, from inverter to the main electrical panel, and from there to the grid connection point. Long runs (e.g., a turbine 200 metres from the building) increase this cost significantly.
If your grid connection point is distant or requires DNO network upgrades, costs can be higher. This is rare but should be confirmed early in the quote.
Design and permitting (5–10% of total)
Some sites need structural engineering (rooftop loading, foundation design) or environmental surveys (ecology, bat assessments). Planning applications require careful preparation and drawings. These are usually built into the installer's quote but can vary.
Site accessibility
Easy access (existing hard standing, nearby parking, clear crane routes) keeps costs down. Difficult access (soft ground, narrow lanes, tree removal) increases installation labour.
Foundation requirements
A site with existing concrete or hard-standing costs less. A site needing a new foundation (pile-driven, concrete pad, or rock-anchored) adds £5,000–£15,000. Rooftop installations need structural assessment but no new foundation.
Electrical distance
A turbine 20 metres from your building is cheaper than one 200 metres away. Long runs need thicker cable, more conduit, and more labour. A 100-metre run adds roughly £2,000–£5,000 to the electrical cost.
Grid connection complexity
Most sites have straightforward G99 applications. Some need DNO network upgrades or reinforcement, which is rare but expensive. Ask your DNO early: "Will my installation trigger a reinforcement?"
Location and travel
Rural or remote sites may incur travel costs for the install team, especially if they are far from the installer's base. Coastal or difficult-access sites may need longer timescales and higher labour costs.
Rooftop vs. ground mount
Rooftop installations avoid foundation work but require structural loading assessment and specialised rigging. Cost difference is usually small — a trade of foundation cost against structural engineering cost.
UK Clean Energy Grants
The Energy Company Obligation and various local authority grants fund renewable installations. Eligibility varies by location and income. Grants typically cover 10–25% of capital cost.
Tax relief and allowances
In the UK, renewable installations may qualify for capital allowances or enhanced depreciation if you are a business. Consult your accountant — this can offset purchase cost against business profits.
Feed-in tariffs and export tariffs
In the UK, the Smart Export Guarantee (SEG) pays you for renewable electricity exported to the grid. Tariffs vary (15–25 p/kWh depending on supplier) but offset operational costs. In Sweden and other Nordic countries, similar schemes exist.
Finance and leasing
Specialist renewable finance providers offer loans or leasing. A £150,000 installation financed at 5% over 10 years costs roughly £1,500/month. But over 10 years, a WindWhisperer 100 Max generating ~230 MWh annually produces £30,000–£50,000 of value (depending on tariffs and self-consumption), so the investment typically repays.
A WindWhisperer 100 Max at a good wind site (IEC Class II or better) generating ~230 MWh annually, with a blended value of £0.25/kWh (combining self-consumption and grid export):
A marginal wind site (more sheltered, lower mean wind speed) with the same turbine:
This is why site assessment matters -- a well-exposed site can repay substantially faster than a poor one.
When requesting a quote, ask for:
A good quote breaks these out separately. Hidden costs usually emerge because a site survey was incomplete — hence the importance of a full survey before quotation.
