Installed a 6.4kW system in November last year. Engagement from all concerns at PSW was excellent. After some minor cosmetic issues at the start, the system has been up and running for nearly 4 months without a glitch! As a bonus, my new system has been producing way above expectations. The first full bill was down to a third of what it was for the same time last year. Loving the Fronius solar web monitoring also.
