We have the expertise and experience required to assist your business in reducing your carbon footprint and electricity costs.

What is a Tier 1 Solar Panel System?

Solar power is broadly recognised as a simple and effective way to reduce your CO2 emissions and energy bills, but not all solar systems are equal. Some simply aren’t designed to cope with Australia’s heat, others don’t deliver the performance a large commercial operation requires. The best way to protect your investment is to select high quality solar products designed to operate in Australia.

Solar panel manufacturers are ranked into three tiers, 1-3. Only a small percentage of solar panels manufacturers around the world have achieved the top Tier 1 ranking. Costline only sells and installs Tier 1 products, giving you the peace of mind of receiving quality products that will provide the best return on investment for your business.

Our 100kW solar system solution is designed for the needs of Australian organisations: efficient, weather resistant, and capable of meeting your power demands on a daily basis.

Quality you can trust

Costline is 100% Australian owned and operated — and one of the country’s leading solar providers for large commercial operators. We have partners in Melbourne, Sydney, Brisbane, and Adelaide and service the entire nation with a large network of professional, qualified installers. Our 100kW solar panel system comes with a 25 year performance warranty, 10 year manufacturer’s warranty, and 5 year warranty on workmanship (including installation).
