Charles was able to answer all of Finn's 7 (or however many) pages of questions on the spot, with confidence and in detail. He came out himself to out house, and send out his installer (Matt) prior to installation for an inspection. The price quoted was cheaper than the other company for exactly the same product (Canadian Solar panels, Fronius inverter). To date we are still waiting for the inspection and paperwork to go through (about 3 weeks so far) but I understand that is largely out of his control. The monitoring system from the inverter indicates very good power production and our power retailer is showing that we are drawing negligible amounts from the grid during daylight hours, other than on the one overcast day we have had to date.
