If your first year's solar savings fall short of the installer's estimate, there are five main reasons this happens. Some are expected and unavoidable; others indicate a system problem or a billing error that can be fixed.
A 6.6kW solar system generates roughly twice as much in December as it does in July. Here's how Perth's seasons affect your solar generation, your electricity bill, and what to do differently in each season.
Every kilowatt-hour your Perth solar system generates either replaces grid electricity you would have bought (at 33.26c/kWh) or exports to the grid under the DEBS scheme (2c/kWh off-peak, 10c/kWh during the 3pm-9pm peak window). Since most solar exports happen during the 2c off-peak window, self-consumption is usually worth 31.26c/kWh more, and still worth 23.26c/kWh more for the smaller share of exports that land in the 10c peak window. Either way, self-consumption is almost always the better outcome, but the practical question is how much you can actually shift.
The more solar you use directly (instead of exporting at 2c/kWh), the better your payback. Without a battery, you maximise self-consumption by shifting appliance loads into solar generation hours. Here's how Perth households do it.
How much of your electricity can you generate and use yourself in Perth? Here's what genuine solar self-sufficiency looks like for a Perth household: what's achievable, what it costs, and why 100% is rarely the goal.
Even a small amount of shade can significantly reduce solar output from a string inverter. Here's how to identify shading risk, what tools installers use, and whether that peppermint tree needs to come down.
A shadow covering just one panel in a Perth string inverter system can reduce the entire string's output. Understanding shading, how inverters respond, and when optimisers or microinverters help is essential for roof assessments.
Shade from trees, neighbouring buildings, and roof structures is the single biggest variable in Perth solar performance. How to assess shading before you sign a solar contract.
Even partial shade on one solar panel can reduce output from the entire string, because standard string inverter systems link every panel into one circuit. Here's how shade propagates, how to tell how much you're losing, and when power optimisers or microinverters are worth the cost.
Commercial solar for Perth small businesses (retail, office, warehouse, and hospitality) works on different economics than residential. Here's what business owners need to understand before getting quotes.
Small businesses in Perth face some of Australia's highest commercial electricity tariffs. Solar can dramatically reduce operating costs, but commercial systems have different considerations than residential. Here's what business owners need to know.

Tile roofs are common on Perth homes built in the 1980s–2000s. Solar installation on tiles is standard, but the mounting method, tile type, and age affect the installation process and cost.
Perth's high solar penetration causes voltage to rise in distribution networks at midday. When grid voltage exceeds inverter limits, your solar system reduces output to protect the grid, even on a perfectly sunny day.
Solar warranties cover three different parties: the panel manufacturer, the inverter manufacturer, and the installer's workmanship. Understanding which warranty applies to your issue (and who to contact first) is the key to a successful claim.
A solar system in Perth comes with three distinct types of warranty. They cover different things, have different claim processes, and matter in different scenarios. Here's how to understand each one.
