The wind turbine is certified according to all leading certification schemes (which approves the turbine for all existing benefits and financial support):Microgeneration Certification Scheme (MCS) in the UKAWEA Certification in the USAClass NK Certification in Japan
THE GIRAFFE
The Giraffe is a hybrid energy production system powered by solar and wind power.
The Giraffe is designed to charge everything from electric vehicles to homes and houses with energy from both wind and sun. The solution consists of a wooden structure that holds 24 solar panels and a wind turbine that is mounted at a height of 12 m. The design was unveiled in 2014 at Asia’s largest design fair – Business of Design Week in Hong Kong. The Giraffe has many applicable areas of use. It can supply renewable energy to summer cottages, villas, lighting or other electrical equipment. The installation can be connected to the grid or used independently with a battery to, for example, replace a diesel generator. In urban environments, the power plant can be used as a charging station for electric vehicles, bus stops or as an education point to spread awareness regarding renewable energy.

Performance
Giraffe 2.0 can produce between 10,000 and 20,000 kWh annually depending on wind and solar conditions. Energy can be generated 24 hours a day, all year round. The unique positioning of the solar panels enables more stable electricity production and results in higher production both in the morning and in the evening.
Installment
The first installation of Giraffe 2.0 took place in Malmö Västra Hamnen at the InnoVentum Demo and Test Site for Renewable Energy Technologies. The installation process is quick after all the sub-modules have been prepared (i.e. the wooden frame mounted on the foundation and the solar panels on the arches). See video of the installation below.The inaugural event for our Demo and Test Site took place in May 2015.
The Advantages of Hybrid Wind and Solar Installations
Wind and solar energy are highly complementary: wind energy is generated mostly during nights and cooler months of the year, whereas solar energy is only generated during daytime, especially in summer months
There are more factors than simple availability of solar insolation that contribute to this complementarity: the air has higher density during winter months and at night, increasing the amount of wind energy generated. Plus, based on climate studies, stable strong winds that make wind energy generation possible, are prevalent during nights and cold months of the year.In this way, energy produced by a hybrid wind-solar power station has much more even flow compared to pure wind or pure solar installations, thus solving the inevitable sinusoidal curve problem that is regarded as the drawback of renewable energy. Such complementarity is the main principle utilised in a hybrid construction like the Giraffe 2.0.
Financial Incentives
Apart from providing energy around the year, the Giraffe 2.0 gives you the opportunity to benefit from subsidies for both solar and wind installations. Please check your local legislation on this account. For example, in Sweden it allows you to qualify for the PV installation support by the Swedish Energy Agency – where up to 30% of total PV system cost can be reclaimed. You can read more here.
