Japanese Windlens unveils residential wind turbine for USD 39,000 - report
Dec 1, 2011 - Japanese wind power start-up Windlens has invented a 5-kW wind turbine for residential and commercial application, which costs only JPY 3 million (USD 39,000/EUR 29,000), including installation, daily Nikkei reported.
The company targets to sell 100 units by the end of March 2012.
According to the developer, the product can compete with solar power systems in terms of costs. Solar power benefits from higher government subsidies, but the wind turbine can also work during the night so the cost per kWh production comes really close to that of solar installations, Nikkei said, citing Windlens.
The turbine represents a modified, 40% cheaper version of an existing wind turbine with a diameter of 3.4-m (11 ft) and an 11.7-m post. Windlens has replaced the metal post with a concrete one, cutting installation expenses by 70%. At the same time, the company has integrated the alternating current/direct current (AC/DC) converter and the DC/AC inverter into a single unit which has fewer parts. This modification has knocked 50% off the conditioner costs, according to the report.
