EVALUATE WIND IMPACT ON SHORT AND LONG STALK
Variables: Constant: Panel shape Panel materiality; Type of clamp; Type of supporting element; Location Manipulating: Length of stalk Responding: Panel deflection
Result: Short stalk > Long Stalk
Criteria to be considered: Width; Length of panel (away from clamp) We observed that the panel would easily deflect with the long stalk, even the wind speed is slow. In contrast, panel with short stalk would only deflect when the wind is strong. However, in term of degree of deflection, short stalk tends to deflect more than the long stalk. Hence, it would be more efficient in term of generate electric. Besides, piezo stalk that less wider can deflect easier than the one wider.
