Onshore wind is an inexhaustible natural resource. It is limitless, clean and economically favorable. Adding wind power to the energy mix of the nation diversifies our clean energy portfolio and helps decrease the targeted countries’ dependence on imported fossil fuels.

Onshore wind power generation increased by an estimated 12% in 2018, while capacity additions increased by only 7%. To get on track with the SDG´s, more efforts are required, and annual onshore wind capacity additions need to improve much quicker by 2030.

ApriSolar is deeply aligned with the framework for progress set by the SDGs. Ensuring access to affordable, reliable, sustainable and modern energy for all is our goal. Using the power of wind resources will help us meet the rapidly growing demand for electricity without compromising energy security and long-term sustainability. It allows us to displace carbon-intensive electricity and reduce greenhouse gas emissions.

Horizontal axis Wind Turbine example


From a technical perspective, ApriSolar’s engineering department can develop multiple wind energy solutions using the most innovative technologies and the world’s leading suppliers of wind turbines. ApriSolar provides solutions that relies on horizontal (HAWT) and vertical axis wind turbines (VAWT). The horizontal axis turbine has a three-bladed propeller that interacts with the headwind. On the other hand, the vertical wind turbine is formed by a set of blades that rotate around a vertical axis. As described below, each type is adapted to different environments.

Our company works with its clients to select the best technology and propose a system based on the most proven, mature and advanced technology on the market. Both vertical and horizontal axis wind turbines are considered in our projects to develop the best solution to our clients. ApriSolar requires suppliers that have carried out trials on their products in extreme weather conditions and
can provide well tested, resilient and versatile Wind Turbines for the markets we operate in.


Horizontal Axes Wind Turbines

Horizontal Axis Wind Turbines (HAWT´s) are the dominant wind turbine on the market and it has been in the running for a long time. They have been pursued in different projects and reached big commercial scales all over the world.

HAWT´s have the main rotor shaft and electrical generator at the top of a tower. In simple terms, the wind exerts forces on the blades (lift and drag) and turns the rotor. The rotor of a horizontal-axis wind turbine must always be oriented so that the plane of rotation is perpendicular to the direction of the wind.

The tall tower of the horizontal wind turbines allows access to stronger wind in sites which means more energy production. HAWTs are designed to deliver maximum wind energy yield for all types of wind conditions (IEC class I, II and III) and in any location. One of the main advantages of vertical wind turbines is in
fact their ability to produce huge amounts of energy in favorable conditions. This technology has a long-term reliability and availability and has proven records in challenging environments.
Through this technology, ApriSolar will be able to meet its clients´ needs in the most sustainable and cost-efficient way.


Vertical Axes Wind Turbines

ApriSolar has signed exclusivity agreements with OEM manufacturers for some regions, countries and projects in our target markets. One of these OEM partners is a manufacturer of Vertical Axis Wind Turbines. (VAWT’s). Vertical Axis Wind Turbines, VAWT´s, have been developed over recent years and represent a unique form of power-generating technology. They are distinguished from standard wind turbines through their unique form and innovative characteristics. The unique characteristics of VAWTS is the fact that they
are able to generate energy at low wind speeds. Our selected VAWTs product can develop energy from as low as 2 meters per second of wind speed, in comparison, a standard wind turbine (HAWTs technology) will only generate energy from 5-6 meters per second of wind speed.

VAWT´s have many advantages over horizontal ones. Principally, the turbine is omnidirectional, which means it doesn't have to rotate to track the wind. This makes vertical-axis turbines simpler and more effective in volatile wind environments; where the wind direction is not always the same. One of the main advantages of vertical wind turbines is their ability to produce energy in wind speeds as low as of 2 metered per second(m/s). This make them the best option in areas where the wind speeds are low, and the space is limited as they are capable to produce higher energy per m2 compared to standard technologies.

In terms of maintenance, VAWT´s represent a lower cost of operation compared to horizontals since they have fewer mechanical components to maintain. This lower maintenance cost also means longer operational life, the product durability and manufacturer’s warranty covers 30 years of energy production, expected operational life is above this.

ApriSolar is convinced that VAWT is the ideal solution for building integration. VAWT´s will allow off-takers in inner-cities across the world, where the wind speeds are lower, to effectively harness the wind to produce energy. This technology is soundless and produces less vibration compared to horizontal ones.

Through this technology, ApriSolar will be able to promote progress, bridge innovation gap, reduce the energy cost and optimize the maintenance cost as well as to persuade off-takers to easily switch to sustainable renewable energies.
