Performance data for two Recipe turbines

New performance data is available from field tests in Holland showing the 1.8 metre diameter turbine producing close to the predicted energy at a 4.8 m/s average windspeed. This turbine is grid-tied using a Mastervolt inverter protected by LDR circuits.

 

Measured energy production versus the tabulated predictions in my book.

 

A similar test had already been done on the 2.4 metre diameter turbine on the same site, although windspeeds were a bit lower.

I love Windpower” is a charity based in Holland with operations in Mali, Tanzania, Malawi, Brazil and Mexico.

They “Educate people in developing countries in small-scale wind energy and in running a business to manufacture, install, sell and maintain small wind turbines.”
