The most important part of a Solar PV System are the panels. Cheap panels are naturally attractive, however they are unlikely to generate the same amount of power as a higher end quality product. In addition, cheaper panels will likely not last as long and a structural warranty might be worthless if the manufacturer stops selling into Australia.
You should only invest in Solar once, so fit the best you can, payback will be far shorter, then you will have free power for years to come.
At CDA we only supply quality panels that are high performing and have rock-solid warranties, that's why we pride ourselves in being a Solargain Authorised Dealer for the Avon Valley and Wheatbelt region.
Sunpower are the longest standing manufacturer of solar panels having started back in 1985 and since produced over 35 million panels. All Sunpower panels have 25-year structural and performance warranties guaranteeing you trouble free power for many years to come.
