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 panel systems are equal. Some aren’t designed to cope with Australia’s heat, others don’t deliver comparable performance. A poorly performing system will limit your sustainability and financial return. The best way to protect your investment is to select high quality solar products designed for life 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.

Our 30KW solar system solution is designed for the needs of Australian business owners: 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 businesses.

We have partners in Melbourne, Sydney, Brisbane, and Adelaide and service the entire nation with a large network of professional, qualified installers.

Our 30KW solar panel system comes with a 25 year performance warranty, 10 year manufacturer’s warranty, and 5 year warranty on workmanship (including installation).
