🚗 Pair with an electric car — charge from your own solar
Solar panels and an EV are the most powerful combination for Irish homeowners. Your roof generates free electricity — your EV turns it into free kilometres. A 4kWp solar system covers approximately 30,000km of free driving per year when you charge at home. See the full EV Vehicle Directory — 205+ electric vehicles available in Ireland.

⚡ Compatible inverters
The Q.PEAK DUO BLK ML-G10+ 405W is compatible with the following inverters — click any to see full specs, pricing and system cost estimates. See the Solar Inverter Directory to compare all 15 inverters available in Ireland.
✅ The Q.PEAK DUO BLK ML-G10+ 405W is compatible with all major Irish inverter brands. Your installer will recommend the best pairing based on your roof size, usage and budget — hybrid inverters (Huawei, Fronius, Sungrow, SolarEdge) are recommended for any home that may want battery storage now or in future.
🔧 Complete your solar system
The Q.PEAK DUO BLK ML-G10+ 405W is Step 1 of a complete solar installation. Here's what you need next:
🧠 Energy Management Systems — get more from your solar
Solar panels generate electricity — an energy management system makes sure it's used at the right time and never wasted. EMS devices can reduce grid import by 10–25% beyond the panels alone, by coordinating generation, battery charging, hot water heating and EV charging. See the full Smart Energy Directory for all EMS products in Ireland.
💡 Why add an EMS to your solar system? Without an EMS, your solar system exports surplus energy to the grid at low export rates (typically €0.09–0.18/kWh via the Clean Export Guarantee). An EMS diverts that surplus to a hot water cylinder, battery, or EV charger — capturing value at your household electricity rate (€0.33–0.36/kWh) instead of the export rate.
🌡️ Pair with a heat pump — maximise your SEAI grants in Ireland
Solar panels and a heat pump are the most powerful renewable combination available to Irish homeowners today. Solar generates free electricity — a heat pump converts that electricity into heat at 3–5× efficiency. Both qualify for substantial SEAI grants. See the full Heat Pump Directory for all models available in Ireland.

💡 Apply BEFORE installation begins. Both the Solar PV and Heat Pump grants require a SEAI Letter of Offer before any contractor starts work. You can apply for both in the same process — ask your installer to coordinate a combined application. Also check: 9% VAT applies to heat pump supply and installation (reduced from 23% since 1 Jan 2025).
☀️ Why solar and a heat pump are the perfect pair: A heat pump runs entirely on electricity — and a solar system generates free electricity from your roof. A typical 4kWp solar system generates ~3,400–3,800 kWh/year. A heat pump for an average Irish home uses ~3,000–5,000 kWh/year for heating and hot water. With both installed, your solar covers a large portion of your heat pump's electricity use — at zero cost. The combination is the highest-savings renewable upgrade available to Irish homeowners today.
🔌 Pair with an EV charger — charge your car from your own solar
Solar panels and an EV charger are the second half of your home energy system. A smart charger draws from your panels first — turning free solar electricity directly into free kilometres. The SEAI Home Charger Grant (€300) applies on top of your solar grant.
🔌 Solar + EV charger: the complete home energy pairing
A solar-compatible smart charger like the myenergi Zappi draws directly from your panels in Eco+ mode — your car charges on electricity you generated for free before it exports to the grid. The SEAI Home Charger Grant covers €300 of your installation cost, and can be claimed alongside your solar grant in the same application.
The Q.PEAK DUO BLK ML-G10+ 405W is the starting point of a complete renewable system. Most Irish homeowners install solar alongside at least one other technology — a heat pump + solar + battery combination delivers the highest savings available on the Irish market today, and both qualify for separate SEAI grants you can apply for together.

❓ Q.PEAK DUO BLK ML-G10+ 405W — frequently asked questions for Irish buyers
A fully installed 4kWp system using the Q CELLS Q.PEAK DUO BLK ML-G10+ 405W costs approximately €5,000 before grants — covering 10 panels, a compatible hybrid inverter, mounting and installation. After the SEAI Solar PV Home Grant of up to €1,800, the net cost is around €3,200. System cost varies by county, roof type, installer and whether you add battery storage. Get 3 quotes through the form above for accurate local pricing.
For a typical Irish home (3–4 bedrooms, ~4,000–5,000 kWh/year electricity use), a 4kWp system using the Q CELLS Q.PEAK DUO BLK ML-G10+ 405W requires 10 panels (each at 405W). This generates approximately 3,600 kWh per year in Ireland — enough to cover 60–80% of average household consumption. Homes with EVs or heat pumps typically benefit from a 5–6kWp system (13–15 panels).
The Q CELLS Q.PEAK DUO BLK ML-G10+ 405W comes with a 25-year performance warranty and a 12-year product warranty. The performance warranty guarantees that the panel will still output at least 80–85% of its original rated power at year 25. The product warranty covers manufacturing defects. Annual degradation is 0.54% — typical for this class of panel.
Yes — the Q CELLS Q.PEAK DUO BLK ML-G10+ 405W is well suited to Ireland's climate. Its low-light performance is rated Good, which matters because Ireland receives a high proportion of diffuse, overcast light rather than direct sunshine. The temperature coefficient of −0.34%/°C means it loses NaN% efficiency per degree above standard test conditions — in line with industry standards. A 4kWp system in Ireland generates approximately 3,600 kWh/year despite our cloud cover.
For Irish homeowners where kerb appeal matters — heritage properties, Victorian terraces, properties visible from the road — all-black panels like the Q CELLS Q.PEAK DUO BLK ML-G10+ 405W are worth the premium (typically €25–€40 more per panel than silver-framed alternatives). The all-black finish (black frame, black backsheet, black cells) is virtually invisible on a dark slate or tile roof. The minor efficiency trade-off from increased heat absorption is less significant in Ireland's cool, mild climate than in warmer countries.
Adding battery storage to a Q CELLS Q.PEAK DUO BLK ML-G10+ 405W system is recommended for most Irish homes. Without storage, surplus solar generated midday is exported to the grid at €0.09–0.18/kWh (Clean Export Guarantee rate) while you buy grid electricity in the evening at €0.33–0.36/kWh. A battery stores that surplus for evening use, increasing self-consumption from ~30% to 70–90%. A typical 10kWh battery (Huawei Luna2000, BYD) adds €3,200–€4,500 to the system cost and has a payback period of 4–7 years alongside the panels.
For homeowners where kerbside appearance matters — particularly on heritage properties, Victorian terraces, or any home where the roof is visible from the road — all-black panels are worth the small premium (typically €15–25 more per panel). The all-black coating absorbs slightly more heat, which reduces efficiency by around 0.5–1% — not significant in Ireland's mild climate. Most Irish homeowners who specify all-black say they would not go back to silver-framed panels.
