I would highly recommend PSW, exceptional service and worry-free installation. I requested a quote for a 5Kw system, but Jesse informed me it would be an overkill after submitting my usage data. We opted for a 3.3Kw system and top of the range panels and inverter. The installers had some bad weather during installation, but no problems, the job was done safely and in a few hours. All rubbish removed after the install. Great job and service guys.
