The use of small wind turbines in business allows the production of green energy. In combination with photovoltaic panels it is possible to produce energy all year round at different times of day and night. Solar panels generate the most energy in the period from March to October. In the autumn-winter period, energy efficiency is much lower. However, wind turbines generate a lot of energy at night and during bad weather. Thanks to a comprehensive solution, the right amount of renewable energy is supplied without CO2 production.
