Panasonic solar panels are not widely available in Australia, so we haven’t had much feedback on them. However, the specs look good, and I believe Enphase has partnered with Panasonic to integrate the panel and inverter. I’d be very confident that this is a high quality system.
However, the price is quite high. This would mean a long payback time for your investment. I would get more quotes, and aim for $2 per watt.
