- Domestic solar PV (typical 3 kW to 6 kW) sized to your roof and usage
- Battery-ready inverters and monitoring so you can track kWh generation
- Optional immersion diverter for hot water self-consumption

How our solar PV installation process works
A good solar PV install is not just panels on a roof. It is a sequence of checks and decisions that affect your generation, safety, and how much of the power you actually use in the home. SolarGuide has been installing solar panels in Ireland since 2017, and our Dublin team keeps the process structured so you always know what happens next. From our base in Dublin 3, we carry out surveys across Clontarf, North Dublin, and the Greater Dublin Area, and we also install regularly throughout Leinster.
The goal is simple: design a system that matches your electricity usage and roof layout, then install it cleanly with proper testing and a handover that makes sense. That is why we start with your usage profile and your meter readings instead of guessing. In many Irish homes, the difference between average and excellent savings comes down to self-consumption. If you can shift flexible usage into daylight hours, solar becomes more valuable per kWh. We factor this into the system size and into add-ons such as monitoring and an immersion diverter.
1) Free site survey and roof assessment
We visit your property and check usable roof area, orientation (south, south-west, east-west), shading, roof pitch, and access. We also check the route for cabling so the finished look is tidy. In Dublin 3 and Clontarf, we often see roof layouts that suit a practical 4 kW to 5.5 kW system, but the right size depends on space and usage, not an average figure.
2) System design and quote (within 48 hours)
You receive a written quote that explains the proposed system size, panel layout, inverter approach, and expected annual generation. We include the effect of the SEAI Solar PV grant where applicable and we highlight what influences performance, such as shade or limited roof space. If you want to understand the cost of solar panels in Ireland in 2026 in broader terms, our pricing guide gives realistic ranges.
3) SEAI grant steps explained in plain English
If you are eligible, we explain the SEAI rules and the timeline. In 2026 the grant is up to €1,800 maximum, calculated as €700 per kWp for up to 2 kWp plus €200 per additional kWp up to 4 kWp. Eligibility typically includes that the home was built and occupied before 2021. The key is to understand what you are signing up for and what information SEAI requires, before work begins.
Read the SEAI grant guide4) Installation and commissioning
A typical domestic solar panel installation in Dublin is often completed in one to two days, depending on roof access and the amount of electrical work required. We install roof mountings, panels, and DC cabling with attention to weather sealing and cable management. Inside, we mount the inverter and connect the system safely to your consumer unit. Commissioning includes testing, monitoring setup, and verification that the system is generating correctly.
5) Handover and ongoing support
You receive a walkthrough of the monitoring app and practical tips to improve self-consumption, such as running appliances at midday where possible and using hot water heating when generation is highest. If you plan to add a solar battery storage system later, we design for that from the start with compatible equipment and space planning.
What affects performance in Dublin and Leinster
Solar in Ireland is less about extreme sunshine and more about consistent daylight. Dublin’s coastal conditions can bring bright spells and fast-changing cloud cover, so we focus on system design that performs reliably over the year. The biggest practical levers are shading, roof layout, and how you use electricity across the day.
- Orientation: south and south-west are strong, but east-west can be excellent for spread-out generation.
- Shade: chimneys, trees and nearby roofs can reduce output. We check this during survey.
- Usage timing: the more you use during daylight, the more valuable each solar kWh becomes.
- Electrical setup: consumer unit condition and cable routes affect the neatness and timeline.
We are based at Alfie Byrne Rd, Dublin 3, and we install across Clontarf, North Dublin and the GDA. If you want a hyper-local view of roof types and typical systems, our Dublin solar panels page covers what we see most often.
Solar panels DublinTypical domestic system sizes
These are common ranges we discuss during surveys. The final recommendation depends on your roof space, shading, and how you use electricity.
| System size | Best for | Notes |
|---|---|---|
| 3 kW to 4 kW | Smaller households, limited roof | Good entry point with grant support |
| 4.5 kW to 5.5 kW | Families aiming to cut bills | Often a strong balance of cost and output |
| 6 kW (and above) | High usage, EV charging, more space | Grant cap still applies, design matters |

Solar PV installation FAQs
Straight answers to common questions about solar panel installation in Dublin, system sizing, and SEAI grant support in 2026.
How long does a solar PV installation take?
Many domestic installs are completed in one to two days, followed by commissioning and monitoring setup. If additional electrical work is needed, we confirm the timeline at survey stage.
Can I get the SEAI Solar PV grant for this install?
Many homeowners can. Eligibility commonly includes that the property was built and occupied before 2021. The grant is up to €1,800 maximum in 2026, based on kWp.
What is a battery-ready solar PV system?
It means the inverter and design are chosen so you can add solar battery storage later without major rework. This is helpful if you want more evening self-supply in the future.
Do you install solar panels outside Dublin?
Yes. We prioritise Dublin and the Greater Dublin Area, and we regularly install across Wicklow, Meath, Kildare and Louth, with nationwide projects when scheduling suits.
How do you estimate payback?
We look at expected annual generation, your usage pattern, and realistic self-consumption. Many households see payback in 5 to 8 years, but the result depends on rates and behaviour.
Will solar work on an east-west roof?
Often, yes. East-west layouts can spread generation across the day, which suits many Irish households. We confirm shading and usable roof area during the site survey.
