With the general reputation in the solar industry (cf double-glazing 20 years ago!) I was pretty wary of dealing with EEC, as I would have been with any company. The salesman (Andy) was - well... - a salesman! But a lot less pushy than many, and generally answered our questions well and was responsive to our specific needs. The installation team (Guy and Jim), that had been given star billing by Andy, actually did live up to their reputation! Very hard-working, they did their best to accommodate our wishes, including running the main cables in a much more difficult location than they could have chosen and generally leaving things clean and tidy. The equipment is functioning extremely well so far, and if it continues to do so, I will consider the price I paid to have been money very well spent. If I have a criticism, it's that the company goes to almost painful lengths to cover its (and, I suppose, my) backside by confirming everything in writing and on the telephone. It gets a bit wearing, but at least you know that everything has been carefully recorded. Overall, precious little to complain about so far.
