Thanks to anyone who might take the time to reply, I appreciate there have been lots of questions about Solar installations already. We have been quoted for Solar by Avid Solar and waiting on a quote by Lightforce. Our house is two storey, four bedroom in Auckland with a 35 degree roof pitch, without much shade obstructing the roof. Our north west facing roof slope can accommodate 14 x 475W Jinko Tiger panels for a total system of 6.65kW. My second question is around the inverter and whether it's noisy.
