Why Irish Farms Are Perfect for Solar
Irish farms have conditions that make solar incredibly effective:
Huge Roof Space
Agricultural sheds offer massive, unshaded south-facing roofs. A typical 40m x 20m dairy shed can accommodate 150-200kW of solar panels — enough to power most dairy operations.
High Daytime Usage
Farm electricity use peaks during daylight hours exactly when solar produces most:
- Milking parlour: 4-7am and 3-6pm peaks
- Tank cooling: All day, highest during and after milking
- Ventilation: Continuous during livestock housing periods
- Feed systems: Usually operate during daylight hours
Excellent Self-Consumption
Unlike homes that export 50-70% of solar production, farms typically use 95%+ on-site. This maximises savings since you avoid both:
- Buying electricity at 30-35c/kWh
- Low export payments at 18-25c/kWh
TAMS III Grant — 60% Funding for Farm Solar

Farm Solar vs. Ground-Mount Systems
Why Roof-Mount is Better
Most farm solar should go on sheds, not in fields:
Advantages of roof-mount:
- No lost agricultural land
- Utilises existing structures
- Lower planning risk
- Better security
- Easier maintenance access
- TAMS eligible
Ground-mount considerations:
- Takes productive land out of use
- Higher planning complexity
- May affect Single Farm Payment eligibility
- More complex TAMS application
- Higher installation costs per kW
Technical Considerations for Farm Solar
Roof Suitability
Not all farm roofs are suitable:
Ideal roofs:
- Corrugated steel or slate in good condition
- South-facing (SE to SW acceptable)
- Unshaded by trees or other buildings
- Structurally sound (certified by engineer)
- Easy access for installation and maintenance
Problematic roofs:
- Asbestos sheeting (can be worked around but adds cost)
- Fibre cement over 20 years old
- Heavily shaded roofs
- Roofs requiring major repairs
Electrical Integration
Farm installations require careful electrical design:
Three-phase connection essential for:
- Systems over 11kW (all farm systems)
- Balanced load distribution
- Integration with existing farm electrical systems
Metering arrangements:
- Export limitation to match on-site consumption
- Half-hourly metering for larger systems
- Integration with existing farm supply
Battery Storage for Farms
While most farm solar doesn’t need batteries due to high daytime usage, some situations benefit:
When Batteries Make Sense
- 24/7 operations: Pig or poultry units with continuous ventilation
- Time-of-use tariffs: Maximise savings on evening peak rates
- Grid stability: Areas with poor grid stability
- Future expansion: Planning for EV charging or heat pumps
TAMS Battery Grant
- Grant covers battery storage up to 50% of solar system size
- 60% grant applies to battery costs
- Typical addition: €8,000-€15,000 for 25-50kWh systems
Planning Permission
Agricultural Buildings
Most farm solar installations are planning exempt under Class 19 of the Planning Regulations:
- Solar panels on existing agricultural buildings
- No change to building use or structure
- Panels don’t exceed roof area by more than 50%
When Planning Might Be Needed
- Ground-mount systems over certain size thresholds
- Listed or protected structures
- Special Areas of Conservation
- Significant visual impact concerns
Lumen Solar provides a planning assessment as part of every farm solar survey.

Frequently Asked Questions
Q: Can I get TAMS grant if I’m not the landowner? A: You must be an active farmer with either ownership or a long-term lease. Family arrangements can work but need proper documentation.
Q: How long does TAMS approval take? A: Typically 8-12 weeks from application submission. We advise applying in autumn/winter for spring/summer installation.
Q: What if my roof needs repairs? A: Roof repairs aren’t TAMS eligible, but we can coordinate with agricultural contractors to get roofs solar-ready.
Q: Can I add more panels later? A: Yes, but you’d need a separate TAMS application. It’s usually more cost-effective to size the system correctly initially.
Q: Does solar affect farm insurance? A: Most farm insurers cover solar installations. We provide technical specifications for your insurance review.
Q: What about ESB Networks connection? A: We handle all grid connection paperwork and liaise with ESB Networks. Most farm installations connect without network upgrades.
