Peter and his team did a great job on the installation of our PV system in September of this year. The work was done professionally, efficiently and in a very competent manner. Communication with Peter and all members of his team was excellent. We are extremely pleased with the results and highly recommend Peter's company for such a project.

We received excellent service from Q4 Energy Solar PV. The installation was quick with no mess. Peter and David took the time to go through the apps and explain everything to me afterwards. We had a one problem after they left but they were back and had the issue resolved within days. Clodagh in the office was very efficient and kept us up to date with everything we needed to know. We would highly recommend the team at Q4 Energy Solar PV.

Very happy with Q4 Solar. Peter came out and assessed our home, put together a very detailed system design (Solar PV + Sigenergy Inverter/Battery) and walked us through the system. He answered all my questions and gave a very reasonable quote. The job iteself was completed in one day and the work was very tidy. We couldnt be happier with the result. Would definitely recommend.

The Q4ENERGY team arrived on time and completed the job within the promised timeframe. The quality of the workmanship was excellent. Since the installation, my energy bills have significantly decreased Highly recommended

Hello, I got Q4 Energy to install 18 panels and an Eddi. I found them to be very professional. Clodagh in the office was very helpful with what paperwork I had to do. I found Peter and David very knowledgeable and were able to answer any questions I had. I'm very happy with the finished job. I would have no problem recommending Q4 Energy to anyone.

I recently installed PV solar panels from Q4 Energy. Peter and David were excellent and very knowledgeable. I was very happy with the work Q4 Energy did for my solar panel installation. From the very beginning, their preplanning and communication stood out. They kept me informed at every stage of the process, clearly explaining what to expect and when. The team was professional, efficient, and respectful of my property throughout the installation. Everything was completed on time and with great attention to detail. It’s clear that Q4 Energy takes pride in their work and truly values their customers. I highly recommend them to anyone considering solar – you’ll be in great hands.

Peter arranged installation of the EV charger within a week of my request. He arrived as promised and installed the charger within a few hours. Very neat job. He helped me load the myenergi app on my phone and showed me how to use it.Very efficient service and I would definitely recommend Q4 Energy.

"I recently had Q4Solar install a solar energy system at my home, which included 10 PV panels, a 5kW inverter, and two 5kW batteries. I’m beyond satisfied with the entire process and the results. The team was incredibly professional and guided me through each step, from selecting the right components to installation and setup. Peter and Dave, the electricians, were particularly outstanding. They were not only skilled and efficient but also friendly and approachable. They took the time to explain everything clearly and made the whole experience seamless. I also want to highlight Cloda in the office, who was efficient and great to deal with. She kept everything organized, communicated promptly, and made the scheduling and administrative process hassle-free. The installation was completed on time, and the workmanship was top-notch. The system has been running smoothly since, and I’m already noticing a significant drop in my reliance on the grid. The two batteries have been especially beneficial, ensuring I have backup power when needed. Overall, Q4Solar delivered excellent service and a high-quality product. I would highly recommend them, and I want to specifically thank Peter, Dave, and Cloda for their exceptional work!"

Got my system set up (12 panels & 8Kwh battery) at end of November. Found Q4 guys easy to work with and knowledgeable. Queries were dealt with quickly by the office support and all documents uploaded to SEAI to support grant application. All, in all I had to do minimal work and everything was done by Q4. Guys were tidy and it all looks well. Got the BER done in first week of Dec and SEAI just approved the payment of the grant. Some tips. Get as many panels as you can fit, they can advise on orientations / optimisers. Get as big a battery as you can so you can charge up with the cheap night rate electricity and run the house off that during the day. There is shag all sun during December so that's the strategy for winter. If you are thinking of getting solar next year apply for the grant now (Dec 24) as it reduces in Jan 25 but if you're approved for it now, it's valid for 8 months.

I engaged Q4 Solar to install a large domestic solar panel installation together with an EV charger in early 2024. Peter and his son, David, explained each step of the work before they started the job. Their technical knowledge is excellent, and the work was carried out in a seamless and professional manner. The workmanship and attention-to-detail were first-class. I highly recommend Q4 Solar … 100% trustworthy and professional.

From the outset Peter and his Q4 team were highly professional in all aspects of the process. From the seamless installation of the panels to submitting the paperwork to SEAI. We received the grant within weeks. We could not rate them highly enough. Completely recommend Q4.

Q4 fitted a solar array and water heating diverter along with car charger. From start to finish a very good experience. I got a personal recommendation from a friend and would now wholeheartedly pass that on to anyone considering using them. Expert installers, all issues with my older property dealt with effortlessly.

Peter and Dave from Q4 Energy are exceptionally professional. Nothing is a problem to them. They installed two EV chargers, one roof mounted and one ground mounted Solar PV system in both mine and my son's houses. They really know their stuff. I couldn't recommend them highly enough. Very satisfied!

I've recently had a PV system installed by Q4 Energy and from start to finish it was a hassle free experience. The installation comprised of 17 solar panels, an invertor and battery. It was great dealing with Peter who delivered exactly what and when he promised to a very high standard . He also advised and helped interface with my EV charger which I had installed previously. I would highly recommend Q4 Energy for PV and indeed EV installations.

Really pleased with the work that Peter from Q4 Energy carried out for me, I had to get a Car charger installed but it was by no means a straightforward job, as it is an older builder it required upgrading of some of the existing system elements, Peter dealt with all of the issues and organised every aspect, from first calling to survey the job I had a quote within a matter of hours and the job was fully completed to a very high standard within 10 days. For efficiency and quality I cant recommend Peter from Q4 energy highly enough
