WA Solar Prices Are Going Up in April 2026. Here Is What Is Actually Happening.

This is the big one.

On 1 April 2026, the Chinese government officially removed the value-added tax export rebate on photovoltaic products. That rebate was sitting at around 9% for PV modules, wafers, and cells. It is now gone.

Why does that matter in Perth? Because the vast majority of solar panels installed on Australian rooftops are manufactured in China. The rebate was effectively a government subsidy on exports, keeping Chinese panel prices artificially low for overseas buyers. With it scrapped, manufacturers are absorbing what they can and passing on the rest. Australian wholesalers are already seeing 9 to 10% increases in panel costs.

Here is the thing most people miss though. Panels only account for about 20 to 30% of the total cost of a residential solar install. The rest is labour, inverters, racking, wiring, and the battery if you are adding one. So a 9% jump in panel prices translates to roughly a 2 to 5% increase in total system cost.

Still real money on a $10,000 to $15,000 install. But not the catastrophe some of the headlines suggest.

The China rebate gets the attention. The raw materials story is just as significant.

Silver is a critical component in solar cell manufacturing, used in the electrical contacts that carry current through the cell. Over the past 12 months, the price of silver has climbed around 35%. In late January alone it jumped over 8% in a single day. Polysilicon, aluminium, and glass are all trending up too.

These are not one-off spikes. They are structural cost increases that panel manufacturers have been absorbing where they can and passing on where they cannot. Solar installers in Australia are already seeing the early effects in their supplier pricing, and Perth Solar Force, who have been tracking this closely, expect it to continue rising throughout the year.

Combined with the VAT rebate removal, the era of solar panels getting cheaper every year has hit a genuine speed bump. Not permanently, probably. But enough that the “I will wait for prices to drop further” logic does not hold up the way it did 12 months ago.

This one is a sleeper.

Perth Solar Warehouse raised a point that does not get enough coverage: there is a genuine shortage of qualified solar installers in WA right now. Rapid growth in renewable energy demand has outpaced the supply of trained electricians and technicians. The result is that homeowners and businesses can expect delays of several weeks or even months if they wait to book their installation.

The maths here is not hard to follow. Australia now has 28.3 GW of rooftop solar capacity across 4.3 million installations. One in three homes generates their own power. The federal Cheaper Home Batteries program, which offers up to 30% off upfront battery costs, is driving a surge in battery installs on top of standard solar demand. The workforce has not scaled to match.

So you have more homeowners wanting solar and batteries, fewer qualified sparkies available to install them, and prices going up while they wait. Getting your quote in early and locking in an installation date, not just an estimated timeframe, is worth doing now.

As if April's price changes were not enough to navigate, Western Australia is introducing new solar and battery connection rules from 1 May 2026 for the South West Interconnected System (SWIS), which covers Perth and most of regional WA.

Here is what is changing. All new or upgraded systems on the SWIS will need to choose between two export pathways: either remote disconnect and reconnect capability controlled by your retailer, or a fixed export limit of 1.5 kW. There is also a new 30 kVA total inverter capacity limit for residential connections, and all inverters must be commissioned to the updated AS/NZS4777.2:2020 standard with Australia Region B settings.

If your system was installed before 1 May, you are completely grandfathered in. But if you are planning a new install or an upgrade, these rules will shape your export options and future ability to participate in virtual power plants.

Solar is still one of the best investments a homeowner can make in Australia, even with prices ticking up. That is not going to change.

But the timing question has shifted. Six months ago, waiting made sense. Prices were stable or falling, installers had capacity, and there was no urgency. Now you have rising panel costs, a raw materials story that is not going away quickly, installer wait times stretching to months in some cases, and new regulations landing on 1 May that will change your export options.

The installers who are paying attention, and Perth Solar Warehouse clearly are, are all saying the same thing: get your quote locked in now. Not out of panic. Because the numbers genuinely favour acting sooner rather than later in this particular window.

And there is one more pressure building that we have not covered here yet: the Iran war and its impact on global shipping routes is adding a third cost layer on top of everything above. That is a separate conversation, and it is worth understanding before you make a final decision on timing.
