• Overall we are very happy with the system now it’s all functioning (9 panels, 5.2kWh battery but more like 4.2kWh usable capacity, Zappi EV charger and iboost water tank heater)• ECH provided excellent and rapid responses by email to all (or at least most) of our questions and concerns• The initial site survey seemed rather cursory and they did not seem to want to inspect the loft or discuss with us the details of the proposal and process or recommended options• It would have been helpful to see a detailed proposal for our home and be kept up to date with delivery dates rather than only in response to our emailed questions. An option for a phone call may have been helpful• It would have also been helpful to be recommended the Eddi for water heater rather than us having to enquire about a water heating system after finding out about this from my colleague and being provided the inferior but admittedly functional iboost option• The delivery of panels, inverter, battery, etc turned up on the Monday 24th April in 2 separate shipments but we didn’t receive information about this other than this may be the date so a confirmation of this by email would have been useful (I worked from home on the off chance)• Similarly, a confirmation about the install date would have been appreciated rather than having to check by email a few days before• One panel was visibly damaged and the delivery driver suggested they were poorly stacked. I was also left to drag the pallet with the battery to the door past our car so I could get this inside before it poured with rain• On the install date (26th April) a traffic incident meant most of the team arrived very late and tired, though the electrician did arrive on time and was able to recommend an alternative option of housing the battery and inverter on the side of the house rather than in the loft as was suggested at the site visit • This confusion over the battery placement meant we hastily arranged to board the loft in advance to speed things up and ensure that it was properly insulated (rather than pay ECH to board a small area around the battery) but this was not needed in the end since the electrician recommended the side wall for battery/inverter• The electrician was excellent, taking us through the process and the system, recommending options and solving issues • But there was a mistake with the wiring which unfortunately was made more difficult to identify due to other equipment failure (dud panel, possibly dud optimiser) and perhaps the fact that a traffic incident severely delayed the installers so there was less time available• The issue was not fixed the next day - the team arrived around 4pm only after a text message exchange which implied they were on site but could not solve the issue despite it being evident they hadn’t yet visited, and when they did it was too wet. We were of course disappointed the issue could not be solved until after the bank holiday weekend but would have understood if we were told it was not possible for the team to attend• Although we really appreciated the hard work the team put in, the panels did not work for nearly a week and the battery was not operating correctly until nearly a month later following multiple emails and eventually getting the electricial back (the export tariff still took longer to sort out but this was not related to ECH who sorted out the relevant information at handover)• It would have been far less stressful if all the installation had gone to plan and I know this was a very unusual situation, though the suggestions about the site visit, more information on the proposal, process and dates all still seem relevant. It would also have been appreciated if some kind of compensation for the problems had been offeredOverall, we are very happy with our solar panels, battery and Zappi charger and the iboost is OK for heating the water tank thougfh an Eddi would probably be much better. The price was competitive and email communication was good. My colleague had a smooth instal with this company so I would see the difficulties as a worst case situation though some of the issues could have been dealt with more effectively but I would still recommend this company as one to get a quote from.
