In Ireland, where open space is plentiful and sunlight can be unpredictable, ground-mounted solar systems have become an increasingly popular alternative to rooftop installations. Many homeowners, farmers, and business owners are turning to solar panels installed on the ground to take full advantage of available land and achieve optimal sun exposure throughout the year.
At EnergyServ, we’ve seen how a well-designed ground-mounted system can deliver decades of reliable energy generation — often outlasting expectations when properly maintained. But just how long can you expect your panels to last, and what factors affect their lifespan?
What Are Ground-Mounted Solar Panels?
Ground-mounted solar panels are installed on steel or aluminium frames anchored directly into the ground, rather than fixed to a roof. This design allows for precise panel tilt and orientation, maximising sunlight capture throughout the year.
They’re especially popular on rural properties, farms, and commercial sites, where there’s plenty of open space. Because these systems can be angled optimally and adjusted over time, they often generate slightly more electricity than rooftop systems installed at fixed pitches.
The Average Lifespan of Ground Solar Panels
High-quality ground-mounted systems are designed to last 25 to 30 years — and many continue producing power well beyond that. In fact, most panels degrade at a rate of about 0.5% per year, meaning they still operate at around 85–90% efficiency after 25 years of use.
Ground installations benefit from improved airflow around each module, which helps prevent overheating. This natural cooling effect can slightly extend the lifespan compared to rooftop systems that are flush against roofing materials.
In Ireland, where temperatures are mild and conditions are rarely extreme, the panels themselves typically outlast the inverters, which may need replacement after 10–15 years.
Why Proper Installation Matters
The quality of installation has a major impact on how long your ground-mounted system lasts. At EnergyServ, we use corrosion-resistant mounting frames, durable cabling, and secure foundations that protect against shifting soil and harsh coastal conditions.
Poorly installed systems, on the other hand, can suffer from loose fittings, poor drainage, or vegetation interference — all of which can shorten lifespan and reduce output. Professional installation ensures every component, from the frames to the wiring, can withstand Ireland’s wind, rain, and temperature changes over the long term.
Comparing Ground and Rooftop Systems
Ground-mounted systems share the same photovoltaic technology as roof panels, but their flexibility gives them a performance edge. Installers can orient them at the ideal angle for Ireland’s latitude, capturing more sunlight in winter and avoiding shading issues from nearby structures.
Because they’re installed at ground level, maintenance is also easier and safer. Our technicians at EnergyServ can inspect, clean, and service ground systems without ladders or roof access, which helps maintain efficiency over time.
Residential and Commercial Lifespans
Both residential solar panels and commercial solar panel installation projects have similar lifespans — the main difference lies in system scale and usage.
- Residential systems are smaller and easier to monitor. Homeowners can spot shading, debris, or vegetation issues quickly and arrange cleaning or maintenance before they affect performance.
- Commercial systems, particularly those powering farms or industrial buildings, are larger and may experience heavier environmental exposure. These typically include automated monitoring tools that track generation and alert the owner to any performance drops.
EnergyServ provides ongoing service packages for both types of clients, ensuring every system operates efficiently and safely for decades.
Protecting Your Investment
To maximise the lifespan of ground-mounted systems, periodic inspections and professional servicing are essential. Over time, soil conditions, weeds, or small animals can affect the base of the structure. Regular checks make sure cables remain secure, mounts stay level, and vegetation is cleared away.
While these systems require little day-to-day attention, scheduling professional inspections every two years helps prevent minor issues from developing into larger problems. Our team at EnergyServ offers maintenance support for both residential and commercial clients, ensuring your system continues to perform at peak efficiency.
Warranty Coverage
Most modern solar panels come with a 25-year performance warranty, guaranteeing they’ll produce at least 80% of their original output by the end of that period. EnergyServ partners with manufacturers whose panels consistently exceed this benchmark, meaning you can expect your system to last well beyond its warranty period.
Mounting structures and inverters typically have shorter warranties (10–20 years), but replacement components are readily available, allowing your system to continue generating clean power for decades.
Ground-mounted solar panels offer lasting performance for Irish homes and businesses.
With professional installation, durable materials, and periodic maintenance, ground-mounted solar panels can deliver clean, renewable energy for 25 years or more. At EnergyServ, we design each system to withstand Ireland’s weather and keep generating value long after the initial investment has paid for itself.
