Solar potential in St Kilda
Here's what panels on a St Kilda roof make, month by month, and what that could mean for your bill.
Updated November 2026 · Litmec Electrical, REC-10383
A 6.6 kW north-facing solar system in St Kilda makes about 9,500 kWh a year: around 35 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. St Kilda ranks 18th of the 38 Melbourne suburbs we've modelled for solar output, but the spread across Melbourne is only 3%: your roof's direction and shade matter far more than your postcode.

These figures use satellite and weather data for St Kilda 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, which is what the site visit checks. Try the roof calculator for your own direction and pitch.
Homes and roofs in St Kilda
Victorian and Edwardian houses, interwar flats and many apartment buildings. Houses can take a system; blocks of flats need a body corporate decision first.
Heritage streets
Many St Kilda streets sit under heritage overlays administered by City of Port Phillip. Panels on rear and side roof faces that can't be seen from the street are usually the simplest route, mounted flush with all-black panels. We check the overlay for your address before quoting. Solar on heritage homes.
Salt air near the bay
Parts of St Kilda are close to Port Phillip Bay. Near the water we specify panels certified for salt-mist exposure (IEC 61701) and corrosion-resistant mounting hardware, because standard fittings corrode faster in salt air.
Older switchboards
A lot of St Kilda housing pre-dates the 1980s, so ceramic fuses, missing safety switches and old fibrous switchboard backings are common. These have to be fixed before solar connects. We're electricians: we check the board on the visit and price any work in the quote. Check your switchboard.
What solar could save in St Kilda
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 St Kilda: questions
How much power do solar panels make in St Kilda?
Each kW of north-facing panels in St Kilda makes about 1,437 kWh a year, so a 6.6 kW system makes about 9,500 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 worth it in St Kilda?
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 could save roughly $600 to $800 a year. Small bills and heavily shaded roofs save less; the site visit tells you honestly.
Do I need council approval for solar panels in St Kilda?
Many St Kilda properties are under heritage overlays with City of Port Phillip, where panels visible from the street may need a planning permit. Panels on rear and side faces are usually simpler. We check your address before quoting.
Does Litmec do solar in St Kilda?
Yes. St Kilda is about 9 km from our base in Newport and well within our 100 km service area. Site visits are free, and your contract and 5-year whole-of-system warranty are with Litmec Electrical.
What size solar system suits a St Kilda home?
Size follows your power use. Most homes paying $350 to $600 a quarter suit 6.6 to 10 kW on single phase. Houses can take a system; blocks of flats need a body corporate decision first.
