Energy systems for the Nordic climate
Energy systems for Nordic climates require solutions that can operate efficiently under constantly changing weather conditions.
Sundirect systems combine solar energy, wind energy, and electricity storage to ensure reliable and efficient performance throughout the entire year.
Solar • Energy storage • Backup mode • Car charging • Drinking water
This is not a standard solar system. It is an integrated energy system designed to reduce costs and use electricity more efficiently.
🟧✓ low solar intensity during winter
🟧✓ changing electricity prices (Nord Pool)
By combining solar panels, energy storage, and smart energy management, the system becomes a unified energy management platform.
What does this mean in practice?
🟧✓ lower electricity bills
🟧✓ energy storage for evenings and nighttime use
🟧✓ backup mode during grid outages
🟧✓ возможность charging an EV using your own energy
🟧✓ drinking water on-site — without deliveries, without plastic, without dependence
🟧✓ more efficient heating when combined with Sundirect infrared heating systems
Why combine it with Sundirect infrared heating?

This means:
🟧✓ heat remains longer inside the building (even after ventilation)
🟧✓ lower heat losses through the air
🟧✓ more efficient use of electricity
🟧✓ an ideal combination with solar panels and energy storage
Result:
100% heat for you. Not for the air.
🟧 Two solutions for different goals
PRO+ — night tariff optimization
ELITE+ — Backup mode (power supply even during grid outages)

Wind Generators — Electricity Even When the Sun Isn’t Shining
Wind generators provide electricity production even when solar panels are not operating at full capacity — during the night, autumn, and winter. In the Nordic countries of Europe, wind is often strongest exactly during these periods, when electricity consumption is at its highest.
Real-world experience shows that during the coldest periods, electricity prices can increase several times over.
By combining wind generators with solar panels and battery storage, it is possible to create a hybrid energy system that provides electricity throughout the entire year.
What does this mean in practice?
🟧✓ electricity even without sunlight
🟧✓ efficient operation during winter and nighttime
🟧✓ reduced dependence on the grid
🟧✓ ideal in combination with battery storage
Important to understand
New technologies (bladeless turbines, vertical-axis systems, wind panels, and micro-turbine solutions) are still in the development stage or designed for specific applications only.
Modern wind generators are capable of starting operation at lower wind speeds (~2.5 m/s), however electricity generation under such conditions remains very limited.
Real and efficient electricity production begins only when there is sufficient wind potential.
In the 5–50 kW segment, practical and proven solutions are still based on the classic horizontal-axis wind turbine combined with modern control technology (pitch control).
🟧 When Solar Energy Decreases — Wind Becomes the Main Energy Source
What Is Pitch Control and Why Is It Important?
Pitch control wind turbines are currently the most advanced technology in small and medium-scale wind power systems.
This type of turbine is becoming increasingly popular in the Nordic countries, as it provides higher efficiency and better electricity utilization under changing wind conditions.
How does it work?
Unlike simple wind turbines with a fixed blade angle, a pitch control system automatically adjusts the blade angle depending on wind speed.
-
this allows efficient use of both low and strong winds
-
the turbine continuously adapts to real operating conditions
-
in Nordic countries, where wind conditions are often highly variable, this is especially important
What does this mean in practice?
🟧✓ up to ~30% higher annual electricity production
🟧✓ starts operating from ~2.5 m/s (works even in low wind conditions)
🟧✓ optimal power output at rated wind speed (~11 m/s)
🟧✓ efficient performance across the entire operating range
🟧✓ pitch adjustment up to ~9° — better utilization of wind gusts and more stable power output
Important to understand
🟧 Pitch control is not an additional feature
-
it determines how efficiently the turbine uses the wind
🟧 Pitch control technology significantly outperforms traditional fixed-blade wind turbines
-
the difference comes not from the wind itself, but from the technology behind the system
Where Do Wind Generators Operate Most Efficiently in Latvia and the Nordic Region?
An incorrectly selected location can reduce the efficiency of a wind generator several times over.
The efficiency of a wind turbine in the Nordic countries is directly dependent on the average wind speed and the specific location.
Wind generators perform best in coastal areas and open landscapes where airflow is not obstructed.
Near the Baltic Sea and the Gulf of Riga, average wind speeds often reach ~6–7.5 m/s, which is considered sufficient for efficient electricity generation.
Where to install a wind generator
🟧✓ coastal areas (Baltic Sea) — the highest wind potential
🟧✓ open rural areas without obstacles
🟧✓ locations near large bodies of water (rivers, lakes)
🟧✓ elevated and wind-exposed areas
🟧✓ recommended average wind speed for efficient operation: from ~6 m/s
Important to understand
🟧✓ the generator can still operate at lower wind speeds
🟧✓ the main requirement is an open location without forests, buildings, or other obstacles
Wind Turbine Installation in Latvia — Main Requirements and Approval Process
Wind turbine installation in Latvia depends on the location, wind conditions, mast height, and the distance to neighboring properties.
In most cases, the process is simpler than it may seem — approval from the local municipal building authority is usually sufficient, and if required, a visual representation of the planned installation may also be needed.
🟧 Main Requirements
🟧✓ municipal approval is required
🟧✓ recommended distance to neighboring properties: ~20–50 m
🟧✓ mast heights up to ~20 m simplify the installation process
🟧✓ open location without forests or buildings
🟧✓ possibility to connect to the power grid or a hybrid energy system
🟧 Mast Height and Technical Logic
🟧✓ we offer 5–50 kW wind generators with 8 m, 12 m, and 20 m masts
🟧✓ these mast heights are optimized for this power range
🟧✓ ensures efficient operation without complex engineering and design requirements
Support and Financing
🟧✓ ALTUM — for businesses (loans, guarantees, capital rebates)
🟧✓ LAD — for agricultural projects (up to ~40–80% support)
🟧✓ EU funds and EKII programs
🟧 Why We Focus on Mast Heights up to 20 m
🟧✓ optimal balance between efficiency and simplified installation
🟧✓ manufacturer-recommended height for this power segment
🟧✓ faster implementation without unnecessary bureaucracy
🟧 What Changes Above 20 m
🟧✓ a full construction project is required
🟧✓ more complex approval procedures and a longer process
🟧✓ higher costs and additional restrictions
🟧 The Reality of the Approval Process
🟧✓ in many cases, a simple approval from the local municipality is sufficient
🟧✓ a visual presentation of the planned solution may be required
🟧✓ requirements depend on the specific location and project conditions

Wind Generators in Latvia – Frequently Asked Questions (FAQ)
Do Wind Generators Work in Latvia?
Yes, wind generators operate effectively in Latvia, especially in coastal areas and open landscapes with average wind speeds from ~6 m/s. A properly selected location is the key factor that determines electricity production.
Does a Wind Generator Produce Electricity at Night?
Yes, wind generators produce electricity during the night, autumn, and winter, when solar panels are not operating at full capacity. These are often the periods when Latvia experiences higher wind potential.
What Type of Wind Generator Is Suitable for Homes in Latvia?
For homes in Latvia, the most suitable solutions are typically 5–50 kW wind generators with pitch control technology, designed for efficient operation under changing wind conditions.
What Is the Minimum Wind Speed Required?
Wind generators can start operating from ~2.5 m/s, however for efficient electricity generation an average wind speed from ~6 m/s over the year is recommended.
Is a Permit Required for Wind Generator Installation?
Yes, wind generator installation in Latvia usually requires approval from the local municipality. Smaller projects (with mast heights up to ~20 m) generally follow a simplified approval process.
What Distance Should Be Maintained from Neighboring Properties?
Typically around ~20–50 meters, depending on local municipal requirements and mast height.
Can a Wind Generator Be Combined with Solar Panels?
Yes, combining a wind generator with solar panels and battery storage creates a hybrid energy system that provides stable electricity production throughout the entire year.
Is Battery Storage Necessary?
A battery is not mandatory, but it significantly improves system efficiency by allowing electricity to be stored and used later when needed.
What Is Pitch Control Technology?
Pitch control is a system that automatically adjusts the blade angle of a wind generator depending on wind speed, increasing electricity production by up to 30% while also improving system stability.
