Solar potential in Somerville
Local solar output for Somerville, from satellite data, plus what Somerville homes usually need on the electrical side.
Updated November 2026 · Litmec Electrical, REC-10383
A 6.6 kW north-facing solar system in Somerville makes about 9,600 kWh a year, about the same as Melbourne: around 36 kWh a day in midsummer and 15 kWh a day in June. East or west-facing roofs make about 85% of that.
On a $450 quarterly bill, that could save roughly $600–800 a year. Somerville ranks 178th of the 429 places across Victoria we've modelled for solar output.

These figures use satellite and weather data for Somerville 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 the Mornington Peninsula and Frankston
The peninsula gets cool sea breezes and mild winters. Many homes are close to the bay or Bass Strait, where salt-mist rated panels and stainless or coated mounting hardware are worth specifying, and holiday homes often have very different summer and winter use.
The Mornington Peninsula and Frankston are on the United Energy network. 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 Somerville, 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.
What solar could save in Somerville
For a home paying $450 a quarter with someone in some days, the calculator suggests a 6.6 kW system saving about $600–800 a year, or $1,000–1,400 with a 10 kWh battery. Your own bill gives a better answer: use the calculator below.

Solar in Somerville: questions
How much power do solar panels make in Somerville?
Each kW of north-facing panels in Somerville makes about 1,455 kWh a year, so a 6.6 kW system makes about 9,600 kWh a year, or 26 kWh a day on average. East or west-facing panels make about 85% of that. (PVGIS satellite data.)
Is solar better in Somerville than in Melbourne?
In the model, panels in Somerville make about the same as Melbourne. Somerville ranks 178th 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 Somerville?
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 Somerville could save roughly $600 to $800 a year. Bigger bills, electric heating and daytime loads save more.
Does Litmec install solar in Somerville?
Yes. Somerville is about 50 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 Somerville?
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.
