5/5

We just wanted to thank all the team at Lennon Solar. We have recently had a complete solar system installed in our house. From the initial meeting with the representative to completion our experience has been marvelous. The team who carried out the project are brilliant ambassadors for the company. They fully understood the situation regarding our home and were first class. From senior installers to apprentices they were a professional in each stage of the project. Can we thank everyone including the office staff for all their assistance.

Fantastic service from the first review through to install. Very thorough company, completed my SEAI grant too. Install was done within a few hours, delighted with my panels. Would also recommend the Eddi system too, fab hot water. Have never looked back nor regretted installing, best decision ever, I generate power even on dull days. Definitely recommend you use Lennon Solar.

We had solar panels fitted 2025 and I'd have to say look no further if you're looking for a reliable installer. After a career in retail I have to say top marks for after sales care and service. Many thanks to all the team for looking after the minor issues efficiently which cropped up. It's a pleasure to deal with a company who still believes in customer service.

Great to work with from start to finish. Thanks to the "Solar Admin" Margaret for making us feeling looked after, Cristian who did the technical assessment of the house with plenty of tips and answers to every question, and the teams - installing the panels very neatly and efficient - again ready to answer every question and the electricians doing a very good job (and hiding the necessary cabling). Questions arising after installation were also solved quickly (involving a further visit). Panels are working fine - and the best of all: Lennon has very competitive pricing... Can only recommend them!

My experience with Lennon Solar was positive. The team from beginning to end was professional and informative. This meant that I was able to make an informed decision on the type of solar system that was best for my residence. I would highly recommend Lennons Solar company!

Before ordering my panels I did as much…

Before ordering my panels I did as much research as possible so that I would be able to cross check replies to questions I would ask the four companies I requested quotes from. Lennon Solar was the only one that did not try to fool me into buying a system they wanted to sell me rather than one which would meet my needs. While all quotes were in the same ballpark, give or take a couple of hundred euros, I decided to go with Lennon. I was glad I did so. They provided me with a considerable amount of literature so that I would fully understand what I was buying. Having placed the order I got a visit from their engineer who planned the system and I was given a date three months from then for installation . As it happens they had a sudden cancellation and were in a position to fit my system after two months which was carried out with incredible efficiency on the day. I could not see what was done on the roof but I have no doubt it was to the same level of skill as was the electrical work at ground level. All anyone has to do is look at the inverter and associated wiring to know that the work is of the highest professional standard possible. I was also impressed by the fact that a month after the installation I got a call to ensure that everything was working well. I would highly recommend Lennon Solar to potential customers.

I had 16 panels fitted almost a year…

I had 16 panels fitted almost a year ago and 4 more with a battery added about 6 months ago. The process went really smoothly, from office to roofers to electricians. Everything went so well and each thing explained so well to me. No one waisted time and the whole job was tidy. clean, on time and professional. My sincere thanks for lovely work that is working so well.

With a large investment, you need to know the company care about that investment too

From the first phone call, to the sales Rep Michael calling out to talk to us, to the installation and the after-sales, all these steps matter when you're laying a lot of hard-earned money on the line. We have always been interested in PV Solar panels and when we moved here in Aug 2022 we decided that the area was made for them so after doing some homework and putting feelers out on the FB solar page we went with 3 quotes. The first was from a national installer who uses very hard-selling tactics and tries to get you signed up straight away to then have Lennon's Michael call out. The difference was worlds apart. Michael walked around with us, explained what the different options were, and advised us on the best option for us. As we have 2 EV's we didn't need the battery that the other company was trying to hard sell to us and the battery we believed we needed. When you get that gut feeling that this is the right company along with recommendations online, you go with that feeling. Lennon has proved beyond all reasonable doubt to us and the family and friends we have recommended them to, who used them too for their installation, that they are by far the most advanced and reliable company out there for Solar installation. You won't find a close match anywhere for their first class Sales, Install, or after-sales service in the country.
