For Irish businesses with sizeable roofs and steady daytime electricity use, solar PV can reduce the amount of power bought from the grid. A 60kW commercial array may be relevant to a factory, warehouse, farm, hotel, workshop, office or retail site—but its value depends on the site’s electricity profile and the portion of generated power that can be used on the premises.
If you are researching the 60kw commercial solar system cost in Ireland, treat any headline figure as a starting point rather than a quote. Roof access, electrical works, grid requirements, equipment and grant eligibility all influence the project budget. This guide explains the main costs and gives illustrative generation and savings calculations. They are not guaranteed results.
What is a 60kW commercial solar system?
Solar PV panels turn daylight into direct-current electricity. Inverters convert it to alternating current for the building’s electrical system. A 60kWp array describes its rated peak capacity under standard test conditions. It does not generate 60kWh every hour or deliver 60kW continuously. Output varies with the time of day, season, weather, orientation, shade and system losses.
The array first supplies electricity used on site. When generation exceeds the building’s immediate demand, surplus may be exported to the grid, subject to the connection approval and export terms. If the system produces less than the site needs, the business continues importing electricity.
Which Irish businesses can benefit from a 60kW solar installation?
A 60kWp system is worth assessing where there is enough usable roof area and a meaningful daytime load. Examples include:
•Factories and workshops: machinery, compressed air, refrigeration and production equipment can use daytime generation.
•Warehouses and farms: lighting, pumps, ventilation, cold stores and processing loads may align with solar hours.
•Hotels and retail premises: kitchens, laundry, refrigeration and building services can provide regular demand.
•Offices: computers, lighting and heating or cooling loads can use some generation directly.
The best fit is not necessarily the business with the largest annual bill. A smaller site with a stable daytime load may use a larger share of its solar generation on site than a much larger business whose demand occurs mainly at night. SEAI recommends examining demand patterns and the building’s suitability before deciding array size.
60kW commercial solar system cost in Ireland
LVP Renewables publishes a broad commercial benchmark of €850–€2,000 per kWp installed. Applying that range to 60kWp gives an indicative calculation of €51,000–€120,000 before any grant. This is a wide planning range, not an LVP quote for a 60kWp project. The company’s published FAQ also notes that larger systems may benefit from economies of scale and that roof type, equipment and site complexity affect the final price.
The public benchmark does not clearly specify whether VAT, scaffolding, battery storage, major electrical upgrades, structural repairs or network connection works are included. Do not assume they are included or excluded without checking the quote. Ask the installer to itemise the scope and state the VAT treatment, grant assumptions, exclusions and any provisional sums.
A complete PV proposal commonly identifies the panels, inverters, mounting system, DC and AC protection, cabling, monitoring, design, installation, testing and handover. It should also specify whether roof surveys, scaffolding or access equipment, board upgrades, export limitation equipment, grid applications, battery storage and civil works are included. Larger electrical or network works can materially change the project cost.
Factors that affect the commercial solar installation cost
The commercial solar installation cost is shaped by both the array and the building it connects to:
•Panels and inverters: Module wattage and quality, inverter specification, monitoring and warranties influence equipment costs.
•Mounting and roof type: Metal, membrane, bitumen and other roofs use different systems. Roof condition and required repair work matter.
•Access and labour: Building height, roof access, scaffolding, safety systems and work-hour restrictions affect installation effort.
•Electrical infrastructure: Existing switchgear, cable routes, distribution board capacity and protection requirements may require upgrades.
•Grid and export connection: ESB Networks may need to assess the connection and permitted export. Any connection or network works should be confirmed before the project starts.
•Project complexity: Shading, roof obstructions, multiple buildings, structural assessments and unusual layouts can add design and installation work.
Request more than one written proposal and compare matching system sizes, assumptions and exclusions—not just the headline price per kWp.
How many solar panels are needed for 60kW?
Panel count depends on the wattage of the modules selected. For a 60kWp array, the arithmetic examples are:
•400W panels: 60,000 ÷ 400 = 150 panels
•450W panels: 60,000 ÷ 450 = about 134 panels
•500W panels: 60,000 ÷ 500 = 120 panels
These counts are estimates. The design must allow for roof shape, setbacks, safe access routes, shading, wind loading and electrical string design. SEAI’s business guide gives an example of a 30kWp system using 75 panels and about 125m² of array area. A 60kWp system could therefore need around 250m² of panel area at that example’s density, plus any space needed for setbacks and access. Actual layouts vary by panel dimensions and roof configuration.
Estimated annual electricity generation from a 60kW system
SEAI’s business guide uses 900kWh per kWp per year as an example for a well-designed, correctly sized, south-facing array inclined close to 35°. Using that reference point, a 60kWp system could generate about 54,000kWh (54MWh) annually. For early budgeting only, a wider planning range of roughly 51,000–57,000kWh a year can be considered if using 850–950kWh/kWp; a site-specific design should replace this assumption.
Actual output varies with location, roof orientation and angle, shading from buildings or equipment, weather, seasonal daylight, module temperature and system losses. The European Commission’s PVGIS tool estimates monthly and annual grid-connected production using location, solar radiation, module and mounting inputs. Ask for a site-specific model rather than relying on a national average.
Potential electricity bill savings and return on investment
The largest factor in solar savings is often how much generated electricity the business uses while it is being produced. Here is an illustrative example, not a tariff quote or guarantee:
•Annual output: 54,000kWh
•Share consumed on site: 70%, or 37,800kWh
•Assumed avoided import price: €0.25/kWh
•Illustrative avoided electricity purchases: 37,800 × €0.25 = €9,450 per year
If the remaining 16,200kWh is exported, it may receive a separate supplier payment. For illustration only, at an assumed export rate of €0.10/kWh, that would add €1,620, giving an illustrative gross energy value of €11,070 per year. Import and export rates are not necessarily the same. CRU says payment is made for metered exported units, while supplier terms and the applicable rate should be checked directly.
On a €51,000–€120,000 indicative system cost, dividing by €11,070 gives a rough simple payback of around 4.6–10.8 years before grant, finance, maintenance, inverter replacement and other project costs. This is a simplified comparison, not an investment forecast. The actual result can differ substantially if the system produces less, the site uses a smaller share on site, tariffs change or the final project cost includes significant additional works. Use actual half-hourly demand and current supplier terms for a proper model.
SEAI commercial solar grants and financial support
The SEAI Non-Domestic Microgen Grant (NDMG) is available to eligible businesses, agricultural premises, public sector bodies, schools, community centres and non-profit societies. The scheme supports solar PV systems up to 1,000kWp. As checked on 14 October 2026, SEAI states that enhanced support applies to new applications made from 6 October 2026 to 6 July 2027. Its published table lists €400 per kWp for systems from 21 to 200kWp. A 60kWp system therefore gives a table-based estimate of €24,000, subject to the offer and the scheme conditions. SEAI also says final payment is the lower of the value shown on the application summary or 45% of the invoiced cost.
For example, 45% of a €51,000 invoice is €22,950, so even where the table-based figure is €24,000, the payment would be capped at the lower amount. The invoice and eligible scope must meet SEAI’s conditions. The grant is not automatic: choose a registered SEAI Non-Domestic Microgen company, apply, and wait for the letter of offer before starting work. Check the current SEAI page and grant calculator before making financial decisions, because scheme windows and requirements can change.
Commercial solar batteries: cost, benefits and suitability
A battery stores some excess daytime electricity for use later. It can increase self-consumption, support peak-demand management or provide backup for selected loads if the system is specifically designed for that purpose. It does not increase solar generation, and its usable energy depends on its capacity, power rating, operating limits and conversion losses.
There is no single reliable public price for a commercial battery that can be applied to every 60kWp solar project. Storage is sized by its energy capacity in kWh and its charge/discharge power in kW, and may require additional inverters, controls, switchgear, fire and safety measures, installation and commissioning. Ask for a separate, itemised battery quote and a financial model. SEAI’s business guide cautions that battery storage installed solely to increase solar self-consumption may not always make economic sense; load shifting or demand-charge reduction may improve the case at some sites.
A business may get more value by first shifting flexible loads—such as pumps, refrigeration, hot water or vehicle charging—into sunny hours. Compare the value of additional on-site use with battery cost, expected cycling, efficiency losses, tariff differences and the battery warranty.
Grid connection, export payments and using solar on site
A 60kWp array’s DC panel rating is not necessarily the same as the inverter’s AC output or the maximum export permitted at the connection point. The connection route depends on the final design and ESB Networks’ technical requirements. Its mini-generation guidance covers specific capacity ranges and says larger generators must use the appropriate small-scale or large-scale generation connection process. A 60kWp proposal should therefore be reviewed by the installer and ESB Networks early; do not assume that a standard NC6/NC7 application or a particular export limit will apply.
Where the system is approved to export surplus, the supplier may pay for metered exported electricity under the applicable arrangements. CRU explains the export payment process, but the supplier’s current tariff and any eligibility or metering conditions must be checked. The rate for exported units can differ from the cost avoided by using solar electricity on site. In most cases, the business should model self-consumption and export separately.
Roof suitability, shade, orientation and installation space
Before selecting a system, check whether the roof is in suitable condition and can safely support the panels and mounting system for the expected service life. Structural capacity and wind loading need professional consideration. Roof repairs before installation may be more practical than removing an array later.
South-facing panels often deliver strong annual output, but east- and west-facing layouts can spread generation across more of the working day. Nearby buildings, roof plant, parapets and trees can cast shade and reduce output. SEAI recommends assessing these factors as part of the system design. Planning exemptions can also depend on building type and location, including Solar Safeguarding Zones and protected structures; check the rules for the specific premises with the planning authority if uncertain.
Commercial solar installation process, maintenance and warranties
A typical project begins with a review of electricity bills and demand data, followed by a site visit and roof/electrical assessment. The installer then designs the array, estimates generation, checks the connection route, prepares a detailed quote and assists with the grant application where applicable. Work should not begin until the SEAI letter of offer is issued and the required grid-connection steps are completed. After installation, the system is tested, commissioned and handed over with documentation and monitoring access.
Solar PV has no moving parts in the panels, but the system still needs monitoring and appropriate maintenance. Ask what visual and electrical inspections are recommended, how faults are reported and what is covered by the panel, inverter, mounting and workmanship warranties. SEAI notes that module output degrades gradually over time and that warranty terms vary by component and manufacturer.
Choosing a reliable commercial solar installer in Ireland
Choose a company with experience on commercial sites and verify that it is registered for the relevant SEAI grant scheme if you intend to apply. Compare proposed generation, panel and inverter specifications, mounting method, roof assessment, connection/export scope, warranties, monitoring and aftercare. Ask whether VAT, scaffolding, board upgrades, batteries and grid works are included or priced separately.
For a proposal that reflects actual operations, provide the installer with recent electricity bills, half-hourly data if available, the Eircode, roof details and any planned changes to machinery or opening hours. LVP Renewables offers commercial PV services for businesses and farms.
