Solar calculatorWhat should you look for in a solar panel?
Tier 1 Status
Look for panels on the Bloomberg NEF Tier 1 list. This is a bankability rating, meaning major banks will finance projects using these panels.
N-type TOPCon Cells
N-type TOPCon is the current standard, replacing older P-type PERC technology. All top-tier panels have switched to N-type in 2024–2025.
25-Year Product Warranty
Minimum 25-year product warranty. This covers manufacturing defects, not just performance. Anything less than 25 years is below the current industry standard.
Performance Warranty
A 25–30 year performance warranty guarantees the panel will still produce 85–90% of its original output at end of life. If it drops below, the manufacturer replaces it.
Efficiency Above 21%
Modern N-type panels should deliver at least 21% efficiency. The top brands achieve 22–24.6%. Higher efficiency means more power from the same roof area.
Low-Light Performance
In Ireland, panels need to perform well in overcast conditions. N-type TOPCon cells have better low-light and temperature coefficients than older P-type panels.
What Are Bifacial Solar Panels?
Bifacial solar panels generate electricity from both sides of the panel. The front captures direct sunlight as normal, while the rear side picks up reflected light (albedo) from the roof, ground, or surrounding surfaces. This can boost total energy output by 5–30% depending on the installation.
| Feature | Bifacial Panel | Standard (Monofacial) Panel |
|---|---|---|
| Light capture | Both sides | Front only |
| Output boost | +5–30% (installation dependent) | Baseline |
| Best for | Ground mounts, flat roofs with white membranes, carports | Standard pitched roofs |
| Cost premium | 5–15% more | Standard pricing |
| Availability in Ireland | Growing. Most Tier 1 brands now offer bifacial options | Widely available |
Are bifacial panels worth it in Ireland?
For standard pitched roof installations, the benefit is modest (5–10%) because there is limited reflected light between the panels and roof. Bifacial panels deliver the best gains on ground-mounted systems where they can be elevated above light-coloured surfaces like gravel, concrete, or grass.
Many of the Tier 1 panels listed above (Jinko Tiger Neo, JA Solar DeepBlue 4.0, Trina Vertex S+) are already bifacial by design. If your installer is quoting one of these panels, you may already be getting a bifacial panel without paying extra. Ask your installer whether the quoted panel is bifacial and whether your mounting setup will allow the rear side to capture reflected light.
See our full bifacial solar panels guide for output gains by install type, cost premiums, and the top bifacial brands available in Ireland, or compare every cell technology in our solar panel types guide.
What is the difference between N-type TOPCon and P-type PERC?
If your installer is quoting a P-type PERC panel, it's likely older stock. Here's why N-type TOPCon is the better choice:
| Feature | N-type TOPCon | P-type PERC |
|---|---|---|
| Generation | Current (2024–2025+) | Previous (being phased out) |
| Efficiency | 21–24.6% | 19–21% |
| Low-Light Performance | Better | Standard |
| High Temperature | Less degradation | More degradation |
| Degradation Rate | 0.3–0.4%/year | 0.4–0.5%/year |
| LID (Light Induced Degradation) | Minimal | Higher (1–3% in first year) |
All top-tier manufacturers have switched their mainstream product lines to N-type TOPCon. If you are offered a P-type PERC panel, ask your installer why. It may be discounted older stock, which can still be good value, but you should be aware of the difference.
Frequently Asked Questions About Solar Panel Brands
Which solar panel brand is best for Ireland?
Jinko solar panels and JA Solar dominate the Irish market. The Jinko solar panel (Tiger Neo N-type) offers 22.3% efficiency, a 25-year product warranty, and excellent value. Both brands are widely available from SEAI-registered installers nationwide.
Does the brand of solar panel matter?
Yes, but less than you might think. All Tier 1 manufacturers produce reliable panels. The difference between brands is typically 1-3% in efficiency. More important factors are your installer's workmanship, system design, and inverter choice.
What does Tier 1 solar panel mean?
Tier 1 is a classification by Bloomberg New Energy Finance based on bankability, not quality directly. It means the manufacturer has supplied branded panels to at least 5 different projects financed by major banks in the past 2 years.
What are bifacial solar panels?
Bifacial solar panels generate electricity from both sides. The front captures direct sunlight while the rear picks up reflected light. This can boost output by 5–30% depending on the installation. They work best on ground-mounted systems or flat roofs with light-coloured surfaces. Many Tier 1 panels (Jinko Tiger Neo, JA Solar DeepBlue 4.0) are already bifacial by design.
How long do solar panels actually last?
Modern panels last 25-30 years. They degrade at 0.3-0.5% per year, meaning after 25 years they still produce 85-90% of their original output. The warranty covers this: if a panel drops below the guaranteed output, the manufacturer replaces it.
