1.- Las curvas presentadas carecen de valor contractual.

H=20

2.- ISOFOTON S.A. se reserva el derecho de realizar modificaciones a estas curvas sin previo aviso.3.- Los valores de caudal y energía están calculados con perfiles de irradiancia según norma IEC 61725, temperatura 35ºC.

4.- En general, las condiciones ambientales difieren de estos supuestos, y por tanto se pueden observar discrepancias entre los valores que presentan las curvas y las medidas en campo
