About Off-Grid Systems
Relying on the grid is getting more expensive and less reliable. That’s why more homes and businesses are turning to off-grid systems.
Off-grid setups aren’t connected to the grid (or only partially) and generate their own power using solar panels and batteries. They’re self-reliant, providing all the energy a building needs—even during outages or in remote locations.
With modern, affordable options, including Victron’s advanced technology, it’s now easier than ever to enjoy uninterrupted, independent power without breaking the bank.

Absolutely delighted with the service from EECO Energy from start to finish. A special mention to Simon Trainor, our client liaison, who was first class throughout. He was extremely responsive, explained everything clearly and continues to quickly answer any questions we have. From confirming the system, the full installation was completed within two weeks, which was brilliant. The roofing team and electricians arrived when they said they would and made sure everything was installed neatly and discreet. We shopped around beforehand and EECO also offered the best price for the system we wanted. The solar and battery combination has been brilliant. We're now at the point where, even on an overcast day, the house is basically running for free from the solar and stored battery power. Great price, professional installation and, most importantly, excellent service before and after the job. Would happily recommend EECO Energy.Posted on Google

Staff are great, big thanks to Simon and Deione, they guided me through the process, helped in every way, a 100% trustworthy company. Installation neat and tidy, roofers A+ electrical install again A+, after service excellent, just lift the phone and like Mr Ben they just pop out of nowhere to answer any queries. Biggest mistake should’ve did it 6 years ago.Posted on Google

EECO Energy recently completed a solar PV and battery installation at our home in Lisburn, and we couldn’t be happier. The roofing and electrical teams were skilled, tidy, and clearly took pride in their work. From the first conversation with Stuart, to the installation, the customer service was consistently excellent. The whole process was smooth, well‑explained, and professionally delivered. We’d happily recommend EECO Energy to anyone looking for a reliable solar installer.Posted on Google

Just had 11.7kw of Panels with a 16kw battery installed by Eeco Energy. It's been a great experience. Simon took the time to call out and spent almost 3 hours explaining not only the process, but the benefits of what he felt was the right amount of kit for our needs, which was to be as close to off grid as possible. The Solar panels (26) went up without any issues last Tuesday and on Thursday the electricians came and installed the battery, inverter and Iboost for the hot water. All the installers were friendly and courteous doing a swift and efficient install and keeping me informed of what they were doing throughout the day. When it first went live, and for a brief period, the app showed a solar generation of 11,500watts from an 11,700 watt array! In the 3 days since, we have drawn virtually no electric from the grid, but sold energy back ( although waiting for our G99 application for electricity buyback to complete). We have our house running on solar, the battery fully charged by midday, and the hot water tank full after a few hours. At night, the battery has been powering the whole house, and we have seen 39% to 40% battery remaining in the morning as solar kicks in and starts the process over again. So far very happy and excited to see how it performs over an extended period, but I have every confidence in the install. Simon has been very quick to respond to queries afterwards as well. Highly recommended.Posted on Google

I have just had a PV system installed with 16 panels and a 16 kW battery by EECO. The whole process from getting a quote and a site survey done, through to installation and commissioning was seamless. The sales lead Gerry was very professional and produced a detailed system design and quote. Gerry did not try and up sell any equipment, as I am an engineer, this was appreciated. The design was exactly what we needed for our household energy consumption. The process from order through to installation was only a couple of weeks. The roofing guys that installed the panels and the electricians who installed the battery and inverter were very competent and did a very tidy job. Messina in admin also very helpful with some queries I had throughout the process. I did get quotes from other installers and EECO were the best value like for like. Overall, I am very pleased that I selected EECO to install my system. I would recommend them to anyone.Posted on Google

We decided to get solar a few months back and did a lot of research regarding the best set up for our needs. We had several local companies provide quotes and proposals and decided to go with EECO for a number of reasons; Product warranties were better than others on the inverter and battery. Prices were very competitive. There was no high pressure sales tactics used and we felt in control through the whole process. Finally, Gerry who provided our proposal and quote was a gentleman. The after sales service is amazing. They regularly contact us to make sure we are satisfied. Already we are saving massive amounts even with an electric vehicle being topped up for free every dayPosted on Google

EECO installed a full solar PV install including battery storage for me recently in Bangor/Ards area. Stuart was great in answering my questions and discussing options before I signed up, he promised me installation within 10 days. The roof guys came earlier than promised after checking that worked for me, fast friendly tidy and efficient in no time the panels were up The electrical guys friendly and efficient talked me though the install and the app, and everything. Messina and all the office people were also patient friendly and helpful. I can't say enough about how positive this process was in terms of customer service. And obviously the solar panels and battery are great, even with our weather I have been electrically self supporting since installation. I would definitely recommend the company and the team.
