I also requested quotes from several other companies, and had a number of salesmen visit to assess my property. During this process I was learning about the various systems and options available, and used this knowledge to tweak the configuration and equipment, gradually refining what I thought I needed for our situation. ECH were quite happy to quote for the various options that I was considering, and also sent a technician to assess the installation, who I found gave me much more insight into the installation possibilities than I had gleaned from talking to all the salesmen from the other companies.
When comparing all the quotes that I received, the best quote was from ECH. Not only that, but ECH quoted for 335 Watt panels, whereas all the other companies had quoted for the cheaper, and slightly inferior, 300 or 310 Watt panels. ECH also stood out from the others by not requiring a deposit from domestic customers, whereas all the other companies wanted a deposit of 25% up front, which is a considerable sum to hand over. ECH seem to be unique in not asking for a deposit from domestic customers.
The actual installation was done extremely efficiently by just two guys in less than a day. The installation was very neat and worked flawlessly from first switch on. Aftercare has also been very good. I have requested various items of documentation to enable us to apply for the export tariff, and response from ECH has been good.
Now that we have had a few weeks experience with the system we are amazed at how well it has performed, especially on a sunny day. Considering that it is only March at the time of writing this, on several days this week solar power has provided 90% of our electricity needs. The monitoring ability of the LuxPower system is brilliant. We can see exactly where our power is coming from and going to at any given time.
I can therefore honestly recommend ECH as the best company to go to if you are considering installing solar panels.
