Why your Donegal price is what it is

The Donegal-specific
cost factors.

All our prices nationwide are based on the same labour and panel rates. Where Donegal differs from Sligo or Leitrim is in three specific local cost drivers — and we show them transparently.

Scaffold rental
€215–€285

Below the all-Ireland midpoint — rural Donegal has lower scaffold rental costs than urban counties.

Scaffold is 2-day rental during install. Included in your fixed-price quote.

Panel choice for Donegal
Longi Hi-MO 6 430W

Our default panel for Donegal based on Ulster distributor stock, warranty terms (25-year linear + product), and Tier-1 status. Longi Hi-MO 6 430W beats competitors on west-coast availability and salt-air tolerance.

Substitutable on request: Longi, SunPower, Trina, Risen — all priced identically.

Inverter lead time
12 days

From order to delivery in Donegal: 12 working days. Above the all-Ireland average due to Ulster distance from our main warehouse. We order at quote acceptance to compress this.

Sungrow / SolaX / GoodWe hybrid inverters stocked. EV-ready models available.

Wind & salt hardware
Class 5 · salt high

Heavy-duty mounting hardware (Hilti CSI rail or KSeven HD) is standard for Donegal due to wind class 5. Adds €120–€180 to the typical install vs. inland counties.

Stainless steel mounting hardware (vs. galvanised) is mandatory for Donegal due to high coastal salt exposure. Adds €80–€140 to the install cost but prevents 25-year corrosion failures.

Cost FAQ · Donegal

Cost questions,
Donegal-specific answers.

All the cost questions Donegal homeowners ask before signing. Numbers below reflect actual Donegal scaffold rates, panel brands and inverter lead times — not all-Ireland averages.

A 4 kWp solar PV system installed in Donegal costs €9,510 fully fitted, or €7,410 after the €2,100 SEAI grant. Range across Donegal sizes: €4,877 (2 kWp net) up to €12,926 (8 kWp net). Donegal's scaffold rental range (€215–€285) and heavy-duty wind-class-5 mounting are baked into these figures.
Three local factors push our Donegal fixed prices right on the all-Ireland midpoint: (1) scaffold rental in Donegal is €215–€285 (Dublin and east-coast urban counties are highest; rural west is lowest). (2) Wind class 5 dictates the mounting hardware grade. (3) Salt exposure (high) determines whether we use galvanised or stainless steel fixings.
For Donegal installs we default to Longi Hi-MO 6 430W — chosen for logistics (our nearest distribution warehouse stocks this brand for Ulster), warranty terms (25-year linear + product), and Bloomberg Tier-1 status. We can substitute Longi, JA Solar, SunPower, Trina or Risen on request — all priced identically.
Inverter delivery to Donegal takes 12 working days from order. Donegal is one of our longer lead times due to Ulster logistics — we order at quote acceptance to compress the timeline. The full install schedule from quote acceptance to commissioning typically runs 25-35 days.
Every fixed-price Donegal quote we issue includes: Longi Hi-MO 6 430W panels, hybrid inverter, heavy-duty mounting hardware, scaffolding (rental €215–€285, included), all electrical works, Safe Electric (RECI) cert, ESB Networks NC6/NC7 notification, the SEAI grant application + tracking, a Letterkenny-area BER reassessment coordinated with a local SEAI-approved assessor, and 25-year panel + 10-year workmanship warranty.
Major roof repairs, fuse-board upgrades (only ~5% of pre-2000 Donegal homes need this), tree pruning, off-grid systems, asbestos cement roof replacement, and apartment-block systems (need management company approval — separate scheme). If your survey flags any of these, we issue an addendum BEFORE work begins. Battery storage is also optional — +€4,200 for a 5 kWh unit.
Yes. We partner with several Irish credit unions and An Post for 0% finance over 5 years for Donegal homeowners. Monthly payment on the typical €7,410 net install: around €132. Average Donegal household monthly ESB savings: €83. Net cash impact from month 1: −€49.
Our peak demand month in Donegal is June. Booking in January-February typically means an install in June (4-6 week schedule). October-December bookings get January installs — quietest months with the shortest lead times. SEAI grant approval (12 working days for Donegal) is the same year-round.
