I have been impressed by the service received from Valo. The original salesman was courteous, knowledgeable and kept us informed (despite considerable health problems). Although there were some minor glitches, the installation team were efficient and polite and kept us informed about issues. The administrative staff at Valo responded promptly and courteously to calls - all issues were addressed promptly and within the specified timelines. The system has now been working problem-free for the first month (19th March to 19th April) and has already supplied 369.74kw/h to the grid.
