Key takeaway: In Melbourne, north-facing panels usually make the most power over a year. East and west roofs still work well, especially if you use power early or late in the day. A tilt of roughly 20° to 35° suits most homes here. Right Choice Solar designs every system around your roof, your shade and your daily routine.
Which way should your panels face? It's the first thing most Melbourne homeowners ask. The short answer is north. But solar panel direction Melbourne homeowners choose isn't always about the biggest yearly total. It can also be about when you use your power. This guide compares north, east and west, covers the best angle, and shows what to do if your roof isn't ideal.
North is usually the best direction for solar panels in Melbourne. Melbourne sits in the southern hemisphere, so the sun tracks across the northern part of the sky. A north-facing panel catches sun from morning to late afternoon.
That gives you the highest yearly output on most roofs. It also gives you a strong midday peak, when the sun is highest.
But "best" depends on how you live. A home that's empty all day has different needs from one with someone working from home. We often see homeowners fixate on the compass and forget their own habits. Your habits matter just as much.
So think of north as the default, not the rule. The best roof direction for solar panels is the one that suits your roof, your bills and your routine.
Here's a simple comparison:
| Direction | When it peaks | Best for | Trade-off |
|---|---|---|---|
| North | Midday | Most homes, highest yearly total | Can overproduce at midday |
| East | Morning | Early risers, morning power use | Weaker afternoons |
| West | Afternoon and evening | Households that use power after 3pm | Weaker mornings |
| South | Low all day | Last resort only | Much lower output |
East and west panels usually produce somewhat less over a year than north. Many Australian guides put the gap at around 10% to 20%. The exact number depends on your roof pitch and shade. It isn't a deal-breaker.
When people compare east vs west facing solar panels, timing is the key. East panels start early and fade by mid-afternoon. West panels start later but keep going into the evening.
For many households, west is the better pick. Why? Power use climbs in the evening. People cook, run heaters and switch on the TV. West-facing panels are still making power at that time. Evening grid prices are also often higher, so every bit of solar you use then saves more.
East suits homes with strong morning use. Think early starts, hot water and breakfast routines.
Direction is only half the story. Tilt matters too. Tilt is how steeply the panel leans from flat.
For solar panel angle Melbourne homeowners can use as a guide, a tilt of about 20° to 35° works well for most roofs. That range balances summer and winter sun. Melbourne is far enough south that winter sun sits low. A steeper tilt helps capture it. A flatter tilt does better in summer.
Here's the good news. Most installers mount panels flat against the roof. Common Melbourne roof pitches already sit in or near that range. So you rarely need to change much.
Flat roof? You can use tilt frames. They lift the panels toward the north at a better angle. The best angle for solar panels in Melbourne on a flat roof is often close to the middle of that range.
Don't chase a perfect number. A few degrees either way barely changes your yearly output. Shade and direction matter far more.
Plenty of Melbourne homes don't have a clean north roof. Terraces, townhouses and units often face east or west. That's fine. You still have good options.
Split the array. Put some panels on the east face and some on the west. You get steadier power from morning to evening. It's a smart way to match a busy household.
Add a panel or two. A slightly larger system can make up the small drop from an east or west roof. It often costs less than people expect.
Use micro-inverters or optimisers. These help when panels face different ways or get partial shade. Each panel works on its own, so one weak panel doesn't drag down the rest.
Try tilt frames. On the right roof, frames can turn panels toward the north.
At Right Choice Solar, we model your roof before we suggest a layout. We look at each roof face and the shade across the day. Then we show you the expected output, so you know what to expect before you sign.
Good best solar panel placement also means keeping panels clear of chimneys, vents and tall trees. A well-placed east or west system will often beat a poorly placed north one.
Here's something many guides skip. Shade can cost you more than direction.
Shade from a tree or neighbouring building can cut output for hours each day. A north roof with heavy shade may do worse than a clear west roof. So check shade first, then direction.
Building a new home? Then you have a rare chance. The best house orientation for solar panels is a roof face pointing close to north. Plan it early, and you'll get the most from your roof for decades.
Good solar installation in Melbourne starts with a real site visit. A quote based on a quick phone call can miss shade, roof angles and switchboard issues.
Before you say yes, check these points:
Accreditation. Look for Clean Energy Council accredited installers.
A written layout. Ask to see where each panel will go, and why.
Expected output. Ask for estimates by roof face.
Warranties. Check both product and workmanship cover.
Clear pricing. Make sure every part and cost is on the quote.
A local team also knows Melbourne's weather and roof styles. That makes the design more practical.
Which direction should solar panels face in Melbourne? North is usually best. It gives the highest yearly output because the sun sits in the northern sky. East and west also work well, depending on when you use power.
Is east or west better for solar panels? West often suits households that use more power in the afternoon and evening. East suits strong morning use. Neither is "wrong". Your routine decides which one fits.
Can I put solar panels on a south-facing roof? You can, but output is much lower. We usually suggest an east or west face first. A south roof is a last resort.
What is the best angle for solar panels in Melbourne? A tilt of about 20° to 35° suits most Melbourne homes. Most roofs already sit near that range. A small difference rarely changes your results much.
How much power do you lose with east-west panels? Typically around 10% to 20% less per year than north, depending on pitch and shade. A split array or an extra panel can help close that gap.
Does roof direction matter more than shade? Often, no. Heavy shade can cut output more than a less-than-ideal direction. Always check shade before you decide on a layout.
Can I split panels across two roof faces? Yes. Many Melbourne homes do. It gives you steadier power through the day and can suit busy households.
Solar panel direction Melbourne homeowners choose should match their roof and their routine. North gives the biggest yearly total. East and west still work well, and good design closes most of the gap. Right Choice Solar can show you the best layout for your home before you commit.
