We chose Glow Green for our solar pv and battery solution not because they were the cheapest (they were quite expensive compared to some). We chose them as they promised an installation within a few weeks. The actual installation started five weeks later than the date promised. The day before the installation started I was contacted and advised the panels I had ordered were not available (even though Glow Green had taken payment for these panels some weeks earlier with the promise that our stock was now secure). We were advised we would get a free upgrade, however on checking the details of the new panels it was clear they were not an upgrade at all. No interest from the design team at that point, simply a comment that as we had lost faith in Glow Green we should cancel. With hindsight this is what we should have done. On the day of the installation we were contacted again and offered an upgraded panel at no cost (following our threat to cancel if not resolved). When we received our new quote I noticed the new design showed less than half our panels actually connected to our battery storage making the system next to useless. At this point the electrician had already installed most of the existing design. Glow Green said it wasn't possible for the system to work the way I wanted (it was and when we explained the solution to them we had another design sent through which cost around £1000 less that the original quote which didn't work) So far so bad..... with half a system installed the engineers left site a week and a half ago leaving equipment scattered around our house in the rain. We have had no update from Glow Green since that day to let us know when we can expect our installation to be completed. We will have scaffolding around our home at Xmas which we had not planned for and as a result our TV signal is blocked. its impossible to contact Glow Green, calling the customer service number just results in 45 min wait only to be told they cannot help and will get someone to call you which never happens
