McDonald O’Brien offer Solahart solar hot water, solar PV and Tesla Powerwall solutions.

Solahart was one of the first companies in the world to recognise the value of the sun’s free energy. solahart-dealerQUOTEFORM

They pioneered solar water heating in Australia in 1953. Since then  have installed over 1 million systems in over 70 countries and have become a world leader in the field of solar energy.

solarToday Solahat’s solar power PV systems are among the most efficient in the world, offering big energy savings to homeowners who switch to solar panels and energy free from the sun.

McDonald O’Brien are qualified to assess your home and provide you with the best systems to meet your family’s needs. Our installers are trained to the highest standards to ensure the safety and effectiveness of your system.

solahart-solar-hot-water-heater-service-installation-15Solahart’s roof mounted tank systems save space at ground level and their elegant simplicity make them  efficient and reliable.

All Solahart solar hot water systems, where the tank is roof-mounted, use the Thermosiphon principle to collect heat from the sun and transfer it to your hot water. The Thermosiphon principle is based on two naturally occurring phenomena:

  • Dark objects absorb heat
  • Hot water rises

Solahart solar collectors are coated with a dark, heat-absorbent surface. This coating absorbs the energy from the suns rays and heats the fluid in the collectors. As the fluid heats, it rises to the top of the collectors and into the tank where it displaces cooler fluid which flows in to the bottom of the collectors where the process is repeated.

Solahart solar power systems which are amongst the most efficient in the world deliver more power for each watt installed. Our solar panels are high performance and made from quality crystalline cells. Each cell is individually tested and power matched to ensure consistent performance between the cells of the panel.

Solahart panels are designed to be durable and engineered to meet the highest quality standards and provide a stable, consistent power output. Our solar panels are certified to International Standards IEC 61215 & IEC 61730 and meet the requirements of all relevant Australian authorities.

tesla-powerwallTesla Powerwall is a lithium ion home battery that charges using electricity generated from solar panels, to power your home in the evening, safely and economically. Completely automated, compact, and simple to install, Tesla Powerwall enables you to maximise self-consumption of solar power generation.

When combined with a new Solahart Solar Power system (photovoltaic panels and inverter), the Tesla Powerwall will allow you to maximise the utilisation of your solar power by storing excess electricity produced during the day for use at any time. You’ll reduce your reliance on power from the grid and lower your power bills even more.
