Daytime load on an industrial roof
The Print Factory is a family print business founded in 1984, producing print, workwear and promotional products from a manufacturing facility in Enniskillen. Its load profile is the classic Northern Ireland commercial one: presses, finishing and building services running through daylight hours.
That is where rooftop solar earns its keep here. With no Smart Export Guarantee in Northern Ireland, the value of a commercial array is almost entirely in the electricity the business uses itself — so generation has to line up with demand, not with an export tariff.
The brief was a fixed-scope commercial install that would satisfy the insurer's pre-install requirements, pass NIE Networks' G99 process and hand over with full electrical certification — without adding battery storage the business did not need for this phase.
Why it mattered to the client
In its own announcement, The Print Factory describes the solar array as part of a wider sustainability programme: printing on demand to cut waste and stockholding, energy-efficient digital and wide-format presses, recycling of paper, card and production waste, FSC-certified papers where specified, and digital workflows that reduce paper use across the business.
The business also frames the investment as resilience — producing its own electricity to protect against rising energy costs while it keeps investing in production technology.
Speaking to Print Business in October 2026, the general manager said the first full month of figures showed the business using less than half the electricity it used to, and called the investment "well worth it".
What we installed
- 108-panel rooftop PV array on the south slope of the steel portal-frame production building, circa 50 kWp
- Solis S6-EH3P40K-H 40 kW three-phase inverter (UK G99 model), running grid-tied with no batteries fitted
- G99 connection application to NIE Networks at 40 kW, handled by us end to end
- Electrical installation to BS 7671 including Section 712, carried out and certified by the NICEIC-approved electrical contractors we work with; PV verification to BS EN 62446-1
- Insurer-ready fire safety package — firefighter rapid shutdown, lockable DC isolation, arc-fault detection enabled at commissioning — plus a structural loading assessment of the roof
Not in scope: Battery storage. The inverter is a hybrid chassis, but this install runs without a battery; adding storage later would be a separate G99 variation.
From survey to switch-on
- Step 1
Survey and design
Roof structure, array layout and the fit against daytime load were checked before a fixed commercial quote was issued.
- Step 2
Insurer and compliance
A written response to the insurer's pre-install requirements, aligned with the FPA RC62 and RE3 guidance for rooftop PV.
- Step 3
Grid
G99 application to NIE Networks at 40 kW, submitted and managed on the client's behalf.
- Step 4
Install and commission
Array and inverter installed and commissioned; handover pack with the electrical installation certificate and PV verification.
- Step 5
Monitoring
SolisCloud monitoring set up so the business can see generation against its own consumption.
The install
What the client gets
- System
- 108 panels · circa 50 kWp array · 40 kW inverter
- Self-consumption
- Generation used on site during production hours
- First full month
- Electricity use more than halved, on the client's own figures
- Annual generation
- Modelled for the roof; early monitoring under way
The first-month result is The Print Factory's own figure, given to Print Business in October 2026. It covers a single month, and generation falls over winter, so it is not an annual saving. Figures vary with weather, usage, tariff and export settings. Northern Ireland has no Smart Export Guarantee, so the value of a commercial array is mainly avoided import. No payback figure is published for this project.
