Why are people getting rid of their solar panels?

It’s a fair question—if solar panels save money and help the planet, why would anyone remove them? The most common reasons revolve around roof repairs, aesthetic preferences, or issues stemming from poor installation.

Reasons for removing solar panels

• Roof repairs or replacement often require panels to be temporarily removed. Some homeowners decide not to reinstall them if the system is old or the cost of reinstallation is high.
• Aesthetic concerns—some homeowners find panels visually unappealing, especially on period properties where planning restrictions may apply.

Improper installation leading to issues

According to a homeowner review on Trustpilot, a poorly installed system caused leaks and reduced generation. That’s why choosing a certified SEAI-registered installer is essential—they follow best practices and offer workmanship warranties that protect you.

Bottom line: For homeowners, panel removal is usually driven by roof work, not product failure. A quality install from a registered professional drastically cuts the chance of future headaches.

The pattern is clear: shoddy installation, not the technology itself, is the primary source of long-term regret.

What is the 20% rule for solar panels?

The 20% rule is a sizing guideline that helps account for real-world losses like shading, inverter inefficiency, and panel degradation over time.

Definition of the 20% rule

It commonly refers to two things: first, that shading should not reduce more than 20% of a panel’s output; second, that oversizing a solar array by about 20% can compensate for anticipated degradation and weather variability. Switcher.ie (energy comparison site) notes that proper sizing is key to achieving the expected payback period.

Why it matters for efficiency

A system that’s too small may not cover your needs; one that’s oversized may take longer to recoup costs. Irish installers often recommend a system size of 4–6 kW for a typical three-bedroom home, which balances generation with roof space.

The implication: ignoring the 20% rule can derail payoff timelines, but a competent installer accounts for it automatically.

How much does a 10kW solar system cost in Ireland?

If you have a larger home or higher energy use, a 10 kW system might be tempting. Here’s what it costs and what you get.

Average cost range for 10kW system

Based on the €1,500–€2,000 per kW benchmark from Switcher.ie (energy comparison site), a 10 kW system before the SEAI grant would cost between €15,000 and €20,000. After the maximum €2,400 grant, the out-of-pocket range drops to roughly €12,600–€17,600. mySolar.ie (Irish installer) estimates typical domestic costs after grant at €5,000–€10,500 for smaller systems, but larger 10 kW installations sit higher.

Breakdown of equipment and installation costs

• Panels: typically 25–30 panels (400W each) – ~€5,000–€7,000
• Inverter: €1,000–€2,000 for a good string or microinverter system
• Mounting, wiring, labour: €4,000–€6,000
• SEAI grant deduction: -€2,400

SEAI grant amounts for 10kW systems

The grant is capped at €2,400 for solar PV, but note that the formula is €700 per kWp for the first 2 kWp and €200 per kWp for the next 2 kWp, maxing at 4 kWp. For a 10 kW system, you only get the grant on the first 4 kWp—so effectively €2,400. SolarTech Online (solar guide) confirms this pro-rata structure.

The catch: the grant’s declining per-kW subsidy means bigger isn’t always better financially.

What is the biggest problem with solar panels?

Solar energy is clean and increasingly cheap, but it’s not without challenges. The biggest issues are intermittency, upfront cost, space, and end-of-life disposal.

Intermittency and weather dependence

Solar panels only generate when the sun shines—Irish cloud cover reduces output, but modern panels still produce 60–80% of their rated capacity on overcast days. Switcher.ie (energy comparison site) notes that a well-oriented system in Ireland can generate 8,500–10,000 kWh annually for a 10 kW array.

Upfront cost and payback

Even with grants, the initial outlay of €5,000–€12,000 can be steep. However, with electricity prices rising, the average payback of 5–7 years makes it a sound investment.

Space requirements

A 4 kW system needs about 20–25 m² of roof space. Not every home has a suitable south-facing roof at the right pitch. An installer will assess your roof’s suitability during a site visit.

Waste disposal issues

Solar panels have a 25–30 year lifespan. Recycling infrastructure is developing, but currently only a fraction of decommissioned panels are recycled properly. Industry initiatives like PV Cycle are working to improve this.

What this means: the technology itself is proven; the main hurdle is the initial investment, which the grant directly addresses.

Who is the most reputable solar company?

Reputation isn’t just about brand—it’s about certification, reviews, and warranty. SEAI registration is the first filter.

Criteria for reputation

• SEAI registration – mandatory for grant access and a sign of compliance with national standards.
• Workmanship warranty – at least 5 years, ideally 10.
• Customer reviews – check Trustpilot or Google reviews for real experiences.

Top SEAI registered installers in Ireland (by region)

Based on listings from The Eco Experts (UK/Ireland solar comparison) and AZ Big Media (industry roundup), here are widely mentioned installers:

• Activ8 Solar Energies – Monaghan, founded 2007
• PV Generation – Cork, founded 2015
• EHP Renewables – Donegal, founded 2009
• East Coast Energy – Meath, founded 2021
• Ohk Energy – Monaghan, founded 2024
• Ecoplex Energy – Dublin, founded 2020
• PureVolt Solar – SEAI approved domestic and non-domestic installer (per their site)

How to check customer reviews

Browse Trustpilot for each company and look for comments on installation quality, after-sales support, and adherence to quotes. A pattern of 4+ stars with at least 20 reviews is a solid baseline.

The implication: SEAI registration is non-negotiable, but it’s just the starting point; real-world reviews and site visits are what separate reliable installers from the rest.

Is 10kW enough to run a house?

For the vast majority of Irish homes, yes—and more. The average Irish household uses about 4,200 kWh per year (Switcher.ie (energy comparison site)). A 10 kW system can generate 8,500–10,000 kWh annually, meaning you’d produce more than double what you need.

Typical household energy consumption in Ireland

Smaller homes (2-bed) use ~3,000 kWh; larger 4-bed homes with electric heating can reach 7,000 kWh. A 10 kW system easily covers all but the most energy-intensive households.

Excess energy and grid sell-back

Under the current microgeneration scheme, you can export surplus electricity to the grid and receive a feed-in tariff. Rates are modest but reduce payback time further. For example, generating 5,000 kWh excess at €0.10/kWh adds €500/year to your savings.

What this means: right-sizing based on your actual consumption and future plans is more important than simply chasing maximum capacity.

Comparison of leading SEAI-registered installers

Four installers, one pattern: all are SEAI-registered with warranties, but their experience and regional focus differ.

The implication: newer companies like East Coast Energy offer longer warranties to compete; older firms like Activ8 provide deep experience. Both are valid—just verify their SEAI status and read recent reviews.

Specifications: what to look for in solar panels and inverters

Six specs, one key takeaway: panel efficiency matters less than total system output and warranty length.

Why this matters: don’t obsess over brand names—focus on the warranty and the installer’s track record. A top-tier panel paired with a poor installation will underperform.

Pros and cons of going solar in Ireland

The pattern: solar works best for homes with good roof orientation and moderate to high electricity usage. Lower-usage homes may still benefit, but the payback will be slower.

Step-by-step: How to choose solar installers near me

1. Check SEAI registration – Use the SEAI registered installer list (available on their website) to find local companies. This is non-negotiable for grant access.
2. Get at least three itemised quotes – Compare not just total price but panel brand, inverter type, warranty length, and estimated annual generation.
3. Verify customer reviews – Check Trustpilot and Google Reviews. Look for comments on communication, installation timeline, and after-sales support.
4. Ask about workmanship warranty – A 5-year minimum is standard; 10 years is better. Ensure it covers leaks and structural issues.
5. Apply for the SEAI grant – You must apply before installation. The grant is paid directly to you after the installer submits evidence.
6. Schedule a site survey – A reputable installer will inspect your roof, measure shading, and confirm suitability before signing a contract.
7. Review the contract carefully – Look for clauses on timeline, payment milestones, and dispute resolution. Never pay the full amount upfront.

The implication: a methodical selection process is the only way to avoid the common pitfalls that lead to underperforming systems and frustrated homeowners.

What’s clear vs unclear about solar installers in Ireland

The pattern: the known facts give you a solid baseline, but the unknowns — installer performance, future tariff rates — require active due diligence rather than passive trust.

“Choosing an SEAI-registered installer is the single most important step for homeowners. It ensures the work meets national standards and that you can access the solar PV grant.”

— SEAI spokesperson (quoted via SolarTech Online)

“Our 4kW system was installed in two days. The electrician was professional, and we’ve seen our bills drop by over 50% since. Definitely worth it.”

— Trustpilot review (verified homeowner)

For Irish homeowners, the choice is becoming clearer: solar is a sound long-term investment when paired with a reputable, SEAI-registered installer. The upfront cost, though real, is mitigated by grants and falling equipment prices. The risk lies not in the technology but in cutting corners during selection. For anyone searching “solar installers near me” in Ireland, the path is simple: check SEAI registration, compare three quotes, and read recent reviews—or risk a system that underperforms for decades.
