If you live in Thornlands, Redlands or wider Brisbane, solar just makes sense. We get strong sun most of the year, plus hot, humid summers where running the air con is non-negotiable. This guide from Solair Electrical walks through the common questions locals ask, then shows you how to use timers, smart settings and daily habits to squeeze the most value from your system.
Common questions we hear (and straight answers)
“Is my roof suitable?”
Most tiled, Colorbond and skillion roofs are fine. What matters more is shade (big trees, neighbouring two storey houses), orientation (north is great; east/west can be excellent for morning/evening use), and roof condition. If your roof needs work soon, tackle that before installing panels.
“How big should my system be?”
Start with your daytime usage. Look at your bill for average kWh/day, then think about when you use power. If you’re home during the day—or you can shift appliances to daylight hours—go a bit larger to cover that load. If the home is empty until late afternoon, prioritise east/west strings or load-shifting strategies instead of just chasing a bigger array.
“Do I need a battery now?”
Not always. Batteries suit households with high evening use, frequent outages, or those wanting backup circuits. If you’re not ready yet, we can design a battery-ready system so you can add storage later without re-doing everything.
“What happens in a blackout?”
For safety, standard grid-connected solar shuts down when the grid goes down. If you want the fridge, lights and internet to keep running, ask us about a hybrid inverter plus backup or a battery with backup circuits.
“What about maintenance?”
Solar is low-touch but not set-and-forget. A periodic clean and a professional check keep performance healthy. If you suspect a drop in output or see error lights, book a solar inspection before summer hits. Ongoing solar maintenance helps catch small issues early and protects warranties.
How to utilise your solar better (Brisbane & Redlands edition)
The goal is simple: use your own solar while the sun’s out, and let the grid top up outside those hours. Here’s how to organise your day.
1) Hot water: let the sun do the heavy lifting
-
Have a timer installed for your electric storage tank to heat between roughly mid morning and mid-afternoon, when your array is punching. An electrician can do this.
-
Heat pump hot water? Great match for solar—set a daytime run window so it sips sunshine, not grid power. Heat pumps are also super efficient to run making them a perfect combo to go with your solar system.
If your hot water isn’t behaving or the element/thermostat looks suspect, we handle hot water servicing promptly so you’re not paying for daytime reheats on the grid.
2) Pool: filter with photons
-
Schedule the pool pump to run mainly through late morning and early afternoon.
-
Split the schedule (e.g., a couple of shorter blocks) so the pump lines up with the sunniest hours.
-
If you’ve got solar heating or a heat pump for the pool, put those cycles into the same daylight window.
3) Air con strategy: pre-cool (or pre-heat) then maintain
Brisbane summers are humid. The trick is to use your solar to condition the home before the evening.
-
Set a comfortable daytime target (often ~22–24 °C in summer) from late morning. Let the system steadily cool and dehumidify while your panels are generating.
-
Close blinds on sun-facing windows and keep doors shut in unused rooms to reduce the cooling load.
-
In the evening, ramp the set-point up slightly (say from 22 °C to 24–25 °C) and use a lower fan speed or “dry” mode to maintain temperature and pull out humidity without blasting the compressor all night.
-
In winter, flip the logic: let solar pre-heat late morning to afternoon, then hold a modest set-point after sunset.
4) Big appliances: move them to the middle of the day
-
Dishwasher & washing machine: run after breakfast or early afternoon.
-
Dryer: if you must, use it while the sun is strong; otherwise, air-dry when possible.
-
EV charging: top up during lunch hours or enable a solar-aware charge mode so your car drinks your excess.
5) Use timers and smart relays
Most inverters and smart meters can switch loads automatically. We can set up:
-
A hot water relay and timer to heat only when solar PV is exporting.
-
A pool pump timer tied to your PV output.
-
Smart plugs for office gear or entertainment systems that don’t need to idle all day.
Design tips that pay off here in SEQ
-
Panel orientation for lifestyle: North boosts midday; east helps breakfast/laundry; west helps late-arvo cooking and air con. Many homes do best with split roof arrays.
-
Shade solutions: If you’ve got occasional shade from trees, module-level optimisation can preserve output on the clear panels instead of dragging the whole string down.
-
Inverter sizing: Slightly under sizing the inverter relative to array size is normal here to harvest more in the shoulders of the day.
-
Monitoring matters: Use the app! Check daily generation vs. self-consumption so you can shift one more appliance into the sunny window each week.
Troubleshooting: small symptoms to jump on early
-
Inverter error lights or random shutdowns.
-
Sudden drop in daily kWh with similar weather.
-
Crackling or heat at isolators or the switchboard.
-
Pool pump/inverter clashes when both start.
Don’t let a minor fault turn into lost generation. We handle solar inverter repairs Brisbane and for a broader range solar repairs Brisbane, from string faults to comms issues, so you’re back to full output quickly.
Maintenance rhythm for Brisbane weather
-
Annual check: Before storm season, book solar inspections to test strings, check isolators, look for hot spots, confirm earthing and update inverter firmware.
-
Panel cleaning: Rain helps, but salt air and dust in the Redlands can leave a film. A gentle clean every 6 months or so keeps production healthy (we’ll advise a safe schedule for your specific roof and pitch).
-
Record-keeping: Keep install docs, warranty cards and photos of the array layout. It speeds up any future solar panel maintenance in Brisbane or warranty claims.
Batteries, now or later?
-
Consider a battery if you want backup power, have high evening usage, or you’re planning EV charging overnight.
-
Not ready? We can design with pre-wired conduits, hybrid-ready inverters and spare switchboard space so adding storage later is simple.
