Just doing my first install. I'm trying to use my local electrical wholesaler as this will help me finance the first job. I'm looking at a 12 panel 3kw installI've had a reasonably competitive quote for conergy 240w panels with a sunny boy hf inverter. They have also quoted for a complete system by solar Europa for about 20% less. They supply all the kit including the inverter which is apparently made in their factory in china.Anyone had any experience with this firm? The kit is mcs certified - is mcs certification a reasonable indication of good quality.Many thanks
