Your journey towards Independence starts with Solar

Installing a solar system requires a high level of knowledge, expertise and precision.

When you choose to install solar with 1KOMMA5°, you'll have access to quality products, from the best brands in Australia.

We have solar systems that suit any home, no matter what your energy needs or goals are.

Battery Storage

Store energy by day, use it when it matter most

Solar panels generate electricity when the sun is up. Your home uses some of this energy and can sell the excess power back to the grid at the prevailing feed-in tariff.

However, at night, power companies may charge you up to ten times the amount they paid for your excess energy. By installing a battery storage system, you can store free energy collected from the sun during the day and use it at night, reducing your reliance on expensive grid power.

Energy Efficient Air Conditioning

Stay Cool and Comfortable with Minimal Energy Use

Air conditioning is essential for maintaining a comfortable living or working environment, but it can also be a significant contributor to your energy bills.

Our range of energy-efficient air conditioning solutions, including split systems and ducted systems, are designed to provide optimal cooling and heating while minimizing energy consumption.

Innovative Solutions

Heat Pump Hot Water Systems

Heat Pump Hot Water systems are an innovative solution for providing hot water in an energy-efficient manner. Unlike traditional water heaters that rely solely on electricity or gas, heat pumps extract heat from the air and transfer it to the water in your tank.

By using solar energy to power the heat pump, you can achieve near-zero operating costs for your hot water system, making it one of the most sustainable choices available.
