Long’s Screen Printing is one of Australia’s longest-running promotional printing companies, starting operations in 1974. Located in Seven Hills, NSW, they use multiple TAS screen printing machines that require a lot of electricity, and they also had high lighting costs due to outdated halogen lights.
1.Significant Cost Savings
Long’s Screen Printing wanted to take control of their rising energy bills. By installing a 30kW solar system, they now generate free, renewable electricity on-site, drastically reducing their monthly energy expenses.
By locking in lower energy costs now, they have also protected their business from future electricity price hikes.
2.Government Incentives & Tax Benefits
We helped Long’s Screening take full advantage of available solar rebates and grants, which lowered the upfront cost of installation.
As a business, they also benefited from asset depreciation tax deductions, making their solar investment even more affordable and financially beneficial.
3.Energy Independence & Reliability
They now rely less on energy providers and more on their own clean, stable power source.
4.Strong Return on Investment (ROI)
Long’s Screen Printing is saving around $8,000 per year on electricity costs, which means their solar system will pay for itself in just 3.5 years.
After that, it’s essentially free energy, and the system has also increased the value of their commercial property.
5.Sustainability & Green Business Credentials
Sustainability is important to Long’s Screen Printing. Their new solar system reduces over 56 tonnes of CO₂ emissions every year, making a big difference in their environmental impact.
6.Low Maintenance, Long-Term Durability
Solar panels require minimal maintenance.
25+ year warranties on panels ensure long-lasting performance.
To help Long’s Screen Printing reduce energy bills and boost sustainability, RK Solar installed a 30kW commercial solar power system using 82 high-quality 365W TrinaSolar panels.
Installed on the North and East sides of the roof
Each panel is connected with a SolarEdge DC Optimiser to maximise performance
One 27.6kW SolarEdge inverter was used
Their old halogen lights were replaced with energy-saving LED High Bay lights, reducing lighting costs by up to 70%
Smart Design for Maximum Power
The inverter was overclocked to generate more electricity even during early mornings and late afternoons, when sunlight is weaker. This ensures the business gets as much energy from the sun as possible.
Results & Savings
The solar panel system at Long’s Screen Printing is now producing around 116.7kWh per day, with an annual solar output of 42.6MWh.
Here is what they are now enjoying:
$8,000 in yearly energy savings
95% solar self-consumption (most of their energy now comes from the sun)
Payback time: only 3.5 years
Return on Investment (ROI): 28%
CO2 emissions are cut by 56.87 tonnes every year, that’s like planting over 2,500 trees!
