Solar potential in St Andrews
Local solar output for St Andrews, from satellite data, plus what St Andrews homes usually need on the electrical side.
Updated November 2026 · Litmec Electrical, REC-10383
A 6.6 kW north-facing solar system in St Andrews makes about 9,100 kWh a year, about 4% less than Melbourne: around 34 kWh a day in midsummer and 14 kWh a day in June. East or west-facing roofs make about 85% of that.
On a $450 quarterly bill, that could save roughly $550–800 a year. St Andrews ranks 393rd of the 429 places across Victoria we've modelled for solar output.

These figures use satellite and weather data for St Andrews from 2005 to 2023 and already allow for heat, wiring and inverter losses. They don't know your roof: shade, pitch and the faces available decide the real number. Try the roof calculator for your own direction and pitch.
Solar in Melbourne's outer north
Craigieburn, Mickleham, Wollert and Mernda are some of the fastest-growing areas in Australia, so most homes are new, with modern switchboards and roofs split into several faces. Further east, Eltham, Diamond Creek and Hurstbridge are leafy, and tree shade is the main design question.
This area is split between the AusNet Services and Jemena networks; your bill shows which one you are on. Your distributor sets how much you can export and approves the connection; we apply for you before anything is ordered.
Acreage, sheds and pumps
Around St Andrews, many properties have sheds, bores or pumps and long distances between buildings. Panels can go on a shed roof or a ground frame, cable runs are designed to keep voltage drop within the wiring rules, and daytime pumping is one of the cheapest ways to use your own solar. Some rural lines (including SWER lines) have tight export limits, which we confirm before you commit. Solar for rural properties.
Backup when the power goes out
Properties around St Andrews can be on long rural lines that are exposed to storms and bushfire. Standard solar switches off in a blackout; a battery with backup wiring keeps the fridge, lights, internet and water pump running. How battery backup works.
Shading from trees
Tall trees are common in and around St Andrews, and shade costs more output than roof direction does. We check shade across the year, including the low winter sun, and use optimisers or microinverters where a few panels can't avoid it.
What solar could save in St Andrews
For a home paying $450 a quarter with someone in some days, the calculator suggests a 6.6 kW system saving about $550–800 a year, or $1,000–1,350 with a 10 kWh battery. Your own bill gives a better answer: use the calculator below.

Solar in St Andrews: questions
How much power do solar panels make in St Andrews?
Each kW of north-facing panels in St Andrews makes about 1,377 kWh a year, so a 6.6 kW system makes about 9,100 kWh a year, or 25 kWh a day on average. East or west-facing panels make about 85% of that. (PVGIS satellite data.)
Is solar better in St Andrews than in Melbourne?
In the model, panels in St Andrews make about 4% less than Melbourne. St Andrews ranks 393rd of the 429 Victorian locations we've modelled. Roof direction and shade still matter more than location: east or west panels cost about 15%, and a shaded roof can cost more.
Is solar worth it in St Andrews?
For most owner-occupied homes with a typical bill, yes. On a $450 quarterly bill with someone home some days, a 6.6 kW system in St Andrews could save roughly $550 to $800 a year. Bigger bills, electric heating and daytime loads save more.
Does Litmec install solar in St Andrews?
Yes. St Andrews is about 43 km from our base in Newport. Site visits are free, and your contract and 5-year whole-of-system warranty are with Litmec Electrical.
Can solar keep my power on during outages in St Andrews?
Only with a battery designed for backup. Standard solar shuts down in a blackout. A backup-capable battery keeps chosen circuits, such as the fridge, lights, internet and water pump, running, and the panels recharge it in daylight.
Who is the electricity distributor in St Andrews?
This area is split between the AusNet Services and Jemena networks; your bill shows which one you are on. The distributor sets export limits and approves the connection; we apply on your behalf before the system is ordered.
