Solar System Performance & Benefits

Your Positive Environmental Impact

When you switch to solar, you’re making a real difference. Over its lifetime, this system is equivalent to planting 427 trees, and it avoids 2 tons of CO₂ per year. This isn’t just a financial decision; it’s a powerful and easy way for your home to contribute to a cleaner, greener future for Ireland.

Solar System Performance & Benefits

Maximise Your Energy Independence

This graph shows your solar system is built to generate a huge 135% of your energy needs every year. In the summer months (May-July), you’re projected to generate nearly 30 kWh/day. This clearly illustrates how you can produce massive amounts of clean power to cover your home’s consumption and truly take control of your electricity bills.

Solar System Performance & Benefits

How Your System Powers Your Home, Day and Night

This simple diagram breaks down the three ways your system works. During the day, excess solar is automatically stored in your battery. When power is needed, the system intelligently draws from the solar and battery before touching the grid. Even at night, you use the stored power first, ensuring you get the absolute maximum value from your investment.

“The Executive Committee of St Patrick’s dwellings for the Elderly CLG (SPADE) contracted Q4 Energy to install solar panels on 24 houses in the summer of 2025. The Committee was very impressed with the work carried out by Q4 Energy. From start to finish, the entire process was handled with professionalism, care, and attention to detail by Peter and his team. The quality of the workmanship exceeded our expectations, and it is clear that great pride was taken in delivering a high standard of service. SPADE also appreciated the clear communication throughout the project, which helped everything run smoothly and on time and both residents and Committee members appreciated the fact that the installation caused minimum interference to the daily routine of the residents. The residents appreciated the information meeting held with Peter who explained the workings and benefits of the solar panels. They, in their turn, commented that their electricity bills already showed credit. It has been a pleasure working with Peter and his team, and SPADE would not hesitate to recommend their services to others.”

– Grace Downey- SPADE

“Peter and his team displayed very effective communication, electrical work, and mechanical skills, at all times; all the work was detail oriented, underpinned by the use of effective hand tools and reflected a great attention to varying detail throughout the entire installation process. Peter is most definitely tech savvy and experienced within the solar industry; it is evident that he is tireless in keeping up with an industry that is consistently modifying and upgrading strategies and proud when professionally providing a good solution for homeowners like ourselves. Peter and his team produced a winning and competitive outcome on our behalf; very much appreciated.”

- Sean Hayes

“I recently had Q4 Energy install Solar PV at my premises, Eddie Walsh’s Bar in Knocknagoshal, and I couldn’t be happier with the whole experience. From start to finish, the team were professional, efficient, and a pleasure to deal with. The installation itself was carried out with zero disruption to the business – the lads were tidy, fast, and clearly knew exactly what they were doing. They also took care of all the grant paperwork for me, which made the process completely hassle-free. Since the panels went up, I’ve already noticed a huge difference in my electricity bills. The savings are fantastic, and it feels good to know the bar is now running more sustainably too. I’d highly recommend Q4 Energy to anyone considering Solar PV, whether it’s for a business or a home. Their workmanship, aftercare, and attention to detail are second to none.”

We got the Gateway switch in case of power cuts and it was explained very well to us. Clodagh, Peter and Brian were all so lovely to deal with and very professional at all times. There was no upselling or 'sales talk'! Would highly recommend.

 Trustindex verifies that the original source of the review is Google. 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.
