Why solar works in Cavan

Cavan's climate, made for solar PV.

Real data from PVGIS (the EU's solar reference database) and Met Éireann. Numbers below are specific to Cavan at 53.99°N, 7.36°W — not all-Ireland averages.

Annual irradiation

980 kWh/m²/yr

Cavan is on the lower side of Irish irradiation, but still well above the viability threshold. Irradiation is what determines how much electricity your panels can produce — and Cavan's value of 980 kWh/m² is comfortably above the 800 kWh/m² minimum where solar PV becomes economically viable. The same data drove SEAI's decision to keep the grant available across all 26 counties of the Republic.

Bright sunshine hours

~1,029 hours/yr

Met Éireann data shows Cavan receives around 1,029 hours of bright sunshine per year. Don't be fooled by Cavan's reputation for cloudy days — solar panels generate from diffuse light too, and the long Irish summer days more than compensate for shorter bright-sun totals. Trend has been stable since the 1990s.

Optimal roof orientation

SSE → S → SSW

For Cavan's latitude (53.99°N), the perfect roof faces due south at 35–40° pitch. East-facing produces ~85% of south output; west-facing ~88%. North-facing roofs can still work with a 12% generation loss — important for Cavan terraced and town-house owners with no choice. We split arrays across two faces routinely.

Seasonal output split

42% / 18%

Roughly 42% of a Cavan system's annual output comes in June–August, while only 18% comes in December–February. This is normal across Ireland and why batteries (or smart export at peak prices) make economic sense — they smooth the seasonal curve and keep ESB bills steady all year.

Monthly generation curve

Jun peak / Dec low

A 4 kWp system in Cavan typically produces around 516 kWh in June (peak month) and just 83 kWh in December. The curve is symmetric around the summer solstice. Cloudy/rainy weeks reduce output by 30–60% vs sunny weeks at the same time of year.

Performance ratio

0.82 – 0.87

Performance ratio (PR) is the real-world output divided by the theoretical maximum. Cavan installs typically run at 0.82–0.87 PR — slightly above the European average of 0.80, helped by Ireland's cool summers (panels are more efficient at lower temperatures). Our crews monitor every install via app for the full 25-year warranty period.

Year-on-year impact · Cavan

Watch your ESB bill shrink, year after year.

A typical 3-bed home in Cavan pays €2,150 a year to ESB. After solar + battery, that drops to under €645 — and the system keeps producing for 25+ years.

Roof types in Cavan

Every Cavan roof,
handled in-house.

Cavan has a mix of roofing styles — from period slate in Cavan to modern concrete tile in the suburbs. Each has its quirks. Here's how we install on each.

Natural slate

Common on pre-1950s Cavan homes, especially in Cavan centre. We carefully lift slates around mount points, install GSE in-roof or proprietary hooks, and replace slates with closed-cell flashing. No drilling through slate. Workmanship guarantee covers any leaks for 10 years.

+0 days · same-day install

Concrete tile

The most common roof type on 1970s–2010s Cavan estates. Standard Tegral, Sandtoft or Marley tiles. We use lift-and-flash mounts that preserve the existing roof membrane. Quickest to install (panels can go up in 4–6 hours on a 4 kWp). Manufacturer warranty unaffected.

+0 days · standard install

Natural clay tile

Found on premium Cavan new-builds and some Cork-style heritage homes. Slightly trickier than concrete — clay is more brittle. We use over-tile clamps with EPDM gasket. We carry replacement clay tiles in our van for any inevitable breakage during install.

+0 days · careful install

Flat felt / EPDM / TPO

Common on extensions, garages, and modern flat-roofed Cavan homes. We use ballasted (no-penetration) systems where possible — keeps your warranty intact. Pitched at 10–15° via aluminium frames for optimum Cavan latitude. Comes with extra wind-load calc.

+0 days · ballasted install

Trapezoidal metal

Standard on agricultural buildings and some modern Cavan eco-homes. Easiest of all roof types — we clamp directly to the metal ribs with rubber gaskets, zero penetration. We've installed many of these for Cavan farms claiming the 60% TAMS 3 grant for solar PV.

+0 days · fastest install

Asbestos cement (we won't)

Found on pre-1990 Cavan farm sheds and some industrial buildings. We don't drill into asbestos roofs — health and safety risk. Solution: replace the roof with metal or felt first (any roofer in Cavan), then we install. We can recommend trusted local roofers who handle asbestos disposal compliantly.

Cavan FAQ

Cavan questions,
Cavan answers.

Pulled from our own enquiries and from Google's People Also Ask box for Cavan solar.

A typical 4 kWp solar PV system on a 3-bed home in Cavan costs around €9,016 fully installed. A 6 kWp system on a 4-bed home runs €11,564–€13,500. After the €2,100 SEAI grant, the net cost in Cavan drops to €7,700–€9,464, fitting includes panels, inverter, scaffolding, electrical work and grant filing.
Based on Cavan's solar irradiation of 980 kWh/m²/year (PVGIS data for 53.99°N, 7.36°W), a south-facing 4 kWp system in Cavan generates 3,330 kWh per year. The average Cavan household saves €1,047 annually on their ESB bill and pays back the full investment in 7.5 years. Add a battery and savings can climb 15–20% higher.
For most Cavan-area homes, yes. With ESB rates above €0.40/kWh, the SEAI grant at €2,100, and the Microgeneration Support Scheme paying ~€0.21/kWh for export, payback periods in Cavan are at historic lows of 7.5 years. Over the system's 25-year warranted life, a typical 4 kWp install nets the homeowner €26,175 versus doing nothing.
Yes, comfortably. Cavan is on the lower side of Irish irradiation, but still well above the viability threshold (980 kWh/m²/year measured by the EU Joint Research Centre). Solar PV panels generate from diffuse light too, so even Cavan's typical overcast days produce 30–60% of peak output. We size every Cavan system using PVGIS data for your specific Eircode — not rough averages.
In almost all cases, no. Since SI 405/2022 (Planning and Development Regulations), solar PV on detached, semi-detached and terraced houses in Cavan is exempt from planning permission with no roof-area cap. Apartments still require planning, and protected structures or homes in Architectural Conservation Areas need approval from Cavan County Council. We confirm everything during the free survey.
Our Cavan crews complete a typical 8–12 panel install in a single working day. Scaffolding is up by 8am, panels and racking are mounted by midday, the inverter and ESB Networks notification are commissioned by 5pm. The full timeline from quote to switch-on averages 4 weeks: free roof survey within 7 days, SEAI grant filed within 14 days, install scheduled within 30 days.
Yes. Under Ireland's Microgeneration Support Scheme (MSS), every Cavan home connected to ESB Networks can export surplus electricity. Suppliers (Electric Ireland, Bord Gáis, SSE, Energia, Pinergy) pay a Clean Export Guarantee tariff of ~€0.20–€0.24/kWh in 2026. The first €400 of annual export income is tax-exempt under Finance Act 2024 — important if your Cavan home generates a surplus.
Cavan averages around 1029 bright-light hours per year, with peak generation between April and September. West-coast counties get fewer sun hours than the south-east, but Atlantic light is exceptionally diffuse — meaning panels still produce on cloudy days. Met Éireann data confirms the trend has been stable for 30+ years, so generation forecasts are reliable.
For a typical 3-bed semi-detached in Cavan consuming 4,500–5,500 kWh/year, a 4 kWp system (10 panels at 400W each) is the sweet spot. It generates 3,330 kWh/year — covering 60–70% of household demand without battery and 80–90% with battery. Cost in Cavan: €9,016 before grant, €6,916 after. Larger 4-bed homes typically need 5–6 kWp.
A 4-bed detached in Cavan typically uses 6,000–7,500 kWh/year — especially if you have an EV or heat pump. We recommend a 5–6 kWp system with 13–15 panels, generating around 4,662 kWh/year locally. With battery storage (5–10 kWh), most Cavan 4-bed households cover 85–95% of their electricity. Total cost: €11,564–€13,500 before grant.
The SEAI Solar Electricity Grant pays €2,100 towards your install. We file the application for every Cavan customer — typical approval lands in 7–10 working days. Combined with Cavan's annual savings of €1,047 and the export tariff, payback on the net cost (€7,700) is 7.5 years. Your home must be built before 31 December 2020 and have an updated BER post-install.
Yes. We partner with several Irish credit unions and An Post's Personal Loan to offer 0% finance over 5 years for Cavan customers. On a typical €7,700 net install (after SEAI grant), the monthly payment is around €128, which is usually less than the monthly ESB savings. No deposit required, no early-repayment penalty. Finance is subject to credit assessment.
Yes, but at lower output. December–February in Cavan typically produces around 200 kWh per month from a 4 kWp system — roughly 18% of summer output. Panels actually run more efficiently in cold weather (their rated output drops with heat), so a sunny Cavan winter day can produce more than a cloudy August afternoon. Most Cavan systems generate around 12 percent of their annual output in winter and 65 percent from May to August.
Most Cavan homes have either slate, concrete tile, or natural tile roofs — all of which take solar PV without issue. Slate (common in older Cavan period homes) needs an experienced installer to lift slates carefully and use proprietary flashings — we handle this routinely. Trapezoidal metal, flat felt, and EPDM roofs also work fine. The only roof we won't install on is asbestos cement (banned since 1999, but still found on some pre-1990 Cavan properties).
Probably yes for most Cavan homes. Most homes here see a stronger battery payback because winter generation is lower and self-consumption matters more. A 5 kWh battery typically adds €3,500–€4,500 to the install but boosts annual savings by €350–€550 by storing midday surplus for evening use. Payback on the battery alone is 8–10 years. Cavan homes with EVs, heat pumps, or evening usage spikes (kids home from school, peak ESB rates) benefit most.
