Where to start with this absolute disaster?My Deege ordeal began in August 2024. Yes, you read that correctly: 2024. Whilst the right make & capacity inverter was installed, it was the wrong model: charging and discharging the batteries at a slower rate than I'd specified. Furthermore, the system pulls about a kWh of energy from the grid every day, even when I'm not at home and peak usage is only around 400W. This occurs regardless of the load placed upon the system or the fact that there is energy available in the batteries to service the load.Getting Deege Solar to respond is a herculean task. They're happy to pick up the phone when they're waiting for payment, but post installation service is atrocious to non-existent. Their phone lines are never answered and e-mails are blatantly ignored. It was October of 2024 before I could get a-hold of someone. The conversation started well, but things went downhill when we disagreed about the inverter discharge rate, with him ultimately, point-blank, refusing to do anything about it as it would cost him too much money.I was told it would be a further six weeks before a site visit could be arranged to correct the excessive power draw. I agreed that they could attend the week before Christmas. Things then went very quiet, so I e-mailed them in mid-December to remind them of their obligation: I got no reply. When the day of the site visit arrived, despite waiting in all day, no-body arrived, nobody e-mailed and nobody called. By this time, I was not exactly surprised.I logged a complaint with HIES, only to learn that Deege had ceased to be a member since 2023, although their website still claimed membership (as a result of my notifying HIES, it no longer does). I've subsequently logged a complaint with MCS, who have referred my case to NAPIT. At this point, Deege did at least come to the table. In light of my experience, I was offered a “system upgrade”: the 6kW Growatt inverter would be replaced by 2 x 3.6kW inverters operating in parallel. This installation was supposed to take place in April 2025, but after their installation team turned-up without any kit, then the wrong kit was delivered, along with numerous other issues, I was left operating on a single 3.6kW inverter for a further three weeks before installation was finally completed in May 2025.It was around this time that I finally got my handover documentation (inaccurate), MCS certificate & G99 registration, but missed out on 8 months of export revenue.Problems persisted with the new system (some even getting worse) & Deege continued to ignore me. Proceedings were then escalated to MCS who served Deege Solar with MULTIPLE suspensions of their license, yet still I was ignored by Deege Solar. Eventually, in late 2025 I was contacted as it seemed they’d noticed there was “an outstanding customer complaint” (it’s about the only thing that is outstanding about this company): I imagine it’s hard to issue MCS certificates to your new customers if you’ve had your license suspended. I also wonder if this is not the first time they’ve had such license suspensions, given it took them 7 months to issue my own MCS certificate.A further “system upgrade” was then agreed & an installation date set. A week before installation, they called to push the date back three weeks, and then failed to attend the new installation date, without any prior notice whatsoever. Via NAPIT & MCS, I’m now claiming a full refund. If they don’t oblige, they’ll be paying solicitors fees and compensation, too.If you're reading this because you're scouting Deege Solar for potential business, I'd encourage you to go elsewhere. No matter what it is about them that is tempting you, re-read my experience and ask yourself if you want to go through the same thing: is it really worth it?
