Sonnen - Quality Solar Systems



Sonnen founded in 2010 is leading German lithium battery system manufacturer and the largest residential battery company in Europe. Until recently Sonnen also known as sonnenBatterie had deployed the largest amount of home battery systems globally, surpassing even Tesla and LG Chem. However, the competition has heated up over the last few years with many low-cost battery systems entering the market. Sonnen, being a premium option also has a premium price & this can be a barrier to those on a tight budget. To help reduce pricing and become more competitive in other markets, Sonnen began manufacturing and assembling systems in California in 2015 & more recently in South Australia (Nov 2018), with the aid of local Government rebates. Sonnen battery owners in NSW, QLD (Energex region), SA, ACT, TAS and VIC have the option of joining sonnenFlat, which enables them to receive a guaranteed annual allowance of electricity from the mains grid for a fixed monthly fee, with supply charge incl.

What They Say

This is how a solar company should operate. Great job by Quality Solar Systems. Information booklet they provide will give you detail idea about all basics of solar energy, Solar Panel manufacturers, Solar inverter Manufacturers and other components which helps you in comparing apples with apples. We realised its not always about the price but quite a lot of other things as well. No sales technique nor do they use any pressure tactic. Very happy customer & highly recommend.

SAM visited my place, explained everything in details and ensured we understood the process. He suggested the best system for our place based on our usage and arranged the installers. The installers have just installed the system and it is working like a charm. Highly recommended team for your solar needs.

I had my solar just installed today and everything was done as promised. I had number of quotes from other company and quality solar has had the best offer with the premium package, i.e. with Fronius inverter and Qcell panels. Roy did a fantastic job getting a solar power in my house. I did not have to pay anything upfront and I have interest free payment, as well.
We had very excellent experience dealing with Quality Solar Systems for our Brissy Property. They arranged obligation free Consultation took us through all technical details, left all the booklets to read through and asked us to ''Compare Apples with Apples''. Sales person visited was very professional, knowledgeable, personable and passionate about doing a great job. we have absolutely no hesitation in recommending them.
