Solar Panels

Solar Inverters


Battery storage technology and pricing has rapidly evolved in recent years and continues to move fast.

With many new brands on the market, we have selected a limited range of battery storage based on proven technology, performance and importantly, the ability of the manufacturer to support a warranty claim in the future.

If you are interested in assessing whether a battery storage system is viable for your existing solar or a new system request a quote from a Harbour Energy consultant.

Home Energy Monitoring

Installing home energy monitoring means you’ll be able to not only see how your solar is performing but you can also view and track total home energy usage.

The are many benefits to total home energy monitoring (or consumption monitoring):

  • Solar owners with home energy monitoring use their solar better and save more
  • You’ll be able to assess whether or when it’s viable to install a battery system
  • You may be able to track faulty appliances (such as hot water systems)
  • You can track which appliances are costly you the most (when all circuits are monitored)
  • You can use it to catch out someone leaving a heater or air-con on!

Even if you’re not an energy geek like those of us at Harbour Energy, we highly suggest having total home energy monitoring installed with your solar system

Add Solar Monitoring to an existing Solar System

Do you have a solar power system without monitoring and you’re not sure if it’s working properly?

Harbour Energy can add a solar and home monitoring to see how your system is performing

In years gone by, many solar systems did not have even basic solar monitoring which meant that the first time solar owners discovered there was a problem was a huge electricity bill.

Fast and efficient – “The quote was quick, easy to understand, detailed and explicit. The installation was done very quickly after accepting the quote and in my absence. I was sent pictures of progress. When I returned home, the system was installed and functioning, with no left over wire or packaging left around the house. I was sent all the details for monitoring the system and everything that was needed by my energy supplier for the system to connect in, was sent through. Overall I was really impressed! ”

Three Systems In And More To Come – “So glad we used Reece and his team for our first system have installed two more since and will be going again shortly with more.”

“Hands down the best customer experience. SunPeak from start to finish were amazing, informative and helped us with every step of the way. Honest approach with respect and integrity. Super happy with SunPeak no hesitation in recommending them to everyone we know.

Michael, Marrickville, 30 April 2019

“Outstanding experience with Sunpeak. We clearly have a complicated roof, one of the suppliers said it wasn’t possible, the other said we could get 2KW max, Sunpeak spent the time (including a house visit and clambering on the roof) to design a 6.6 kw system. From the get go the team were simply awesome to deal with. Reece spent heaps of time talking us through the options, and Carl and the team were on-site within 2 weeks and it is clear these guys are not just installers, they are craftsmen. The result is a fantastic system that is exceeding our expectations. Can’t recommend the Sunpeak team enough! “

Paul, Annandale, 11 March 2019

“Was really satisfied from the initial consultation to the final installation. At all times the team communicated with me regarding progress. The Installers are professional and do an excellent Job. I highly recommend them to other consumers looking for a quality solar installation. “
