Rotor

What is it That DETERMINE what to wear for the size (scan area) on a rotor? It is of course So THAT the larger rotors That you have on your work, the more power you will gain in low winds but less or no effect at all in high winds. It is very Difficult to DETERMINE how large a rotor to be and it's tempting to put on a larger rotors to produce more power in less wind. The problem with a large rotor Is that once it is very windy so it is Difficult to hold back and slow down whichcould have serious Consequences (The Work "runaway" and / or the generator windings melts, and in extreme cases, it May Come off The wings). Something you can do is to select rotors for where you live. For example,live on the CoastYou might choose a rotor for högvind (small rotor) and the hinterland, where the winds are less perhaps Choosing a rotor Designed for lågvind (larger rotor). A lågvindsrotor Reaches nominal at about 9-10m / s and a högvindsrotor Reaches the rated power at about 12-13m / s.
