Price breakdown by system size

Understanding typical ranges helps you spot fair vs expensive quotes.

2-3 kW systems

Typical range: €4,500-7,000 before grants

After grant: €2,700-4,600

Price per kW: €1,800-2,300

Best for: Small homes, apartments, limited roof space

4 kW systems (most common)

Typical range: €6,500-8,500 before grants

After grant: €4,100-6,100

Price per kW: €1,600-2,100

Best for: Average family homes (3-4 beds)

5-6 kW systems

Typical range: €8,000-11,000 before grants

After grant: €5,600-8,600

Price per kW: €1,500-1,900

Best for: Larger homes, heat pumps, high usage

7+ kW systems

Typical range: €11,000-14,000 before grants

After grant: €8,600-11,600

Price per kW: €1,400-1,800

Best for: Very large homes, maximising roof capacity

Larger systems have better value per kW due to economies of scale.

What affects the price you’re quoted

Several factors explain why quotes vary for seemingly similar systems.

Equipment brands

Budget tier (lowest cost):

Panels: Trina, Jinko, Canadian Solar
Inverters: Growatt, Goodwe

Mid-range (most popular):

Panels: Longi, JA Solar, Risen
Inverters: Huawei, Solis, Sofar

Premium tier (highest cost):

Panels: SunPower, LG, REC
Inverters: SolarEdge, Fronius, SMA

Premium equipment adds €1,000-2,000 to system cost but offers better warranties, efficiency, and monitoring.

Roof characteristics

Standard roof (baseline pricing):

Single south-facing plane
Easy access
No obstructions
Good condition

Complex roof (adds €500-1,500):

Multiple orientations
Difficult access (scaffolding)
Shading (requiring optimisers)
Flat roof (mounting frames needed)
Old roof needing repairs

Inverter type

String inverter: €800-1,500 (standard)

Hybrid inverter: €1,500-2,500 (battery-ready, more features)

Micro-inverters: Adds €800-1,500 (better for shaded roofs)

Company factors

Established large companies: Higher overheads (showrooms, marketing) but more stability and support.

Smaller installers: Lower overheads, competitive pricing, but check track record and financial stability.

Location: Urban vs rural makes little difference (€200-500 max).

How to compare quotes

When you receive multiple quotes, compare systematically:

1. Compare system specifications

Don’t just compare total prices—check:

Total kW capacity
Panel brand, model, and wattage
Inverter brand and model
Warranties offered
Monitoring features included

2. Calculate price per kW

Divide total cost by system size:

€7,200 for 4 kW = €1,800/kW
€8,500 for 5 kW = €1,700/kW

This helps compare different-sized quotes.

3. Check what’s included

Ensure quotes include:

All equipment and installation
Scaffolding
Electrical certification
SEAI grant application
ESB Networks notification
Warranties

Quotes missing items aren’t comparable.

4. Research installer reputation

Check:

Google reviews
Trustpilot ratings
SEAI registration status
Years in business
Number of installations completed

A slightly more expensive quote from a reputable installer beats a cheap quote from an unknown company.

5. Assess value, not just price

Consider:

Equipment quality and warranties
Installer experience and support
Monitoring and features
Company financial stability

The cheapest option isn’t always the best value.

Typical price by installer type

Different installer types have different pricing structures:

Large national companies:

Price range: Upper-middle to high
Example: €7,500-9,000 for 4 kW
Pros: Established, financial stability, good support
Cons: Higher overheads reflected in pricing

Regional installers:

Price range: Middle
Example: €6,500-7,800 for 4 kW
Pros: Competitive pricing, local knowledge
Cons: Varies widely—check reputation carefully

Small local electricians:

Price range: Lower-middle to high (varies hugely)
Example: €6,000-8,500 for 4 kW
Pros: Can be very competitive
Cons: Less experience, financial stability questions

Energy suppliers (SSE, Bord Gáis, etc.):

Price range: Upper-middle
Example: €7,000-8,500 for 4 kW
Pros: Brand trust, bundled offerings
Cons: May not be cheapest, using subcontractors

Red flags: when to walk away

Be cautious if an installer:

Quotes significantly below market rate without clear explanation
Pressures you to sign immediately with “limited time offers”
Can’t provide SEAI registration or insurance documents
Offers vague equipment specifications (“high-quality panels”)
Has very few or very negative reviews
Won’t provide itemised quotes
Quotes system sizes that don’t match panel quantities (e.g., “10 × 400W panels = 5 kW”)

Negotiating on price

You can often negotiate, particularly if:

You have multiple quotes: “Company X quoted €6,800 for the same system—can you match it?”

You’re flexible on timing: “Can you offer a discount if I’m flexible on installation date?”

You’re paying cash: Some installers offer small cash discounts (€200-400).

Expect €300-800 flexibility, not massive discounts. If an installer immediately drops their price by €2,000, question their original pricing.

Frequently asked questions

What’s a fair price for solar panels in Ireland?

For a typical 4 kW system, €6,500-8,000 before grants (€4,100-5,600 after grants) represents fair market pricing with decent equipment and reputable installer.

Should I always choose the cheapest quote?

No. Equipment quality, warranties, installer reputation, and service matter. Middle-priced quotes often offer best value. Only choose the cheapest if equipment and installer quality match competitors.

How much can I negotiate?

Typically €300-800 on a €7,000-8,000 system. Larger discounts suggest inflated initial quotes. Some installers have fixed pricing and won’t negotiate.

Do prices include VAT?

Yes, quotes should be VAT-inclusive. Residential solar installations are subject to 13.5% VAT (reduced rate). Check quotes state “inc. VAT.”

Will prices fall if I wait?

Equipment costs have been stable for 3-4 years. Waiting is unlikely to save much, and rising electricity prices mean earlier installation means sooner savings.
