I must say your team were very professional and did a great job. I would also like to take this opportunity to praise Rheice who from the moment I dealt with him on the phone was excellent, knowledgeable and gave me the best advice and products to go for. On behalf of my wife & I, we would like to thank your staff & installers for a great job and I have no hesitation in recommending your business to others.

FORGET ROI. It means nothing. The objective is simple. You are purchasing an appliance to remove an issue which exists in your life.

Why buy a car if it is only going to get you 3/4 of the way to the city where you have to get out and walk the remainder?

Why purchase a washing machine which can only do a half cycle? And would you ever purchase a 3 legged table? Fact is, with any other appliance you utilise, including that Thermomix, ROI is irrelevant. You purchase it for a purpose.

Compare solar batteries to discover which is ideal for you and which is most likely to do the whole job.

If you thought selecting the ideal solar panels was a confusing process, welcome to the world of ideal battery selection.

Nonetheless, your friendly team at PSW have your solar battery questions answered!

Is there a battery rebate in WA?

No.

Available subsidies for Perth & Bunbury region WA exist only around carbon offset emissions on generation capacity, such as the solar array size.

Combining solar with batteries as a whole will allow subsidising of the entire package, but no more than if solar is installed without the battery.

Can I install a larger battery capacity over solar panel rating?

Yes.

This is because basic system sizes in solar vs battery are completely different.

Solar PV systems are advertised as kW. This is the amount of peak power the combined system can produce as a whole at Standard Test Conditions.

Battery systems are sized by kWh. Is is a more accurate reflection of supply ability over time. The peak power of a battery is often determined by the inverter it is connected to.

Will I still receive REBS if I add a battery?

Quite Likely.

If you qualify for the Renewable Energy Buyback Scheme (REBS) you can receive 0.07c (7.1350 ex GST) for each unit (kWh) exported by your solar energy system.

As long as the battery is set to zero export and the solar inverter capacity isn’t being increased, it’s quite likely (subject to Synergy approval) you’ll still qualify for REBS.

Can I add batteries to an existing solar system?

Yes.

It’s all about battery selection. Potentially the easiest battery to to add to an existing standard solar energy is referred to as AC coupled in the variants such as the Tesla PowerWall 2 and the SENEC.Home range.

Alternative DC coupled battery options are available for standard string inverters in the form of the SolarWatt Matrix range.

Can I view a working example of a PSW batteries before buying?

Yes.

Almost all battery brands are available for viewing at the PSW Research Centre. It’s advised to always check prior to arrival though due to stock rotations.

How much do batteries cost?

$1.99 for a 2 pack of AA’s from Coles. Wrong answer, right? In all seriousness though, it all depends on what you want the solar battery to do. If you are looking at storing solar energy for later use with no back-up functionality, this is the most affordable option.

Want to capitalise on a solar batteries back-up features? Expect to pay more for the luxury as individual installation specifics will always play a big part. There is no average here.

The mother of all, off-grid. A well thought out energy assessment and a sizeable investment is required when compared against any advertised prices or basic battery system. Battery deals >
