Solar potential in Kew
What solar would make on your Kew roof, what it could save, and what to check before you buy.
Updated November 2026 · Litmec Electrical, REC-10383
A 6.6 kW north-facing solar system in Kew 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 86% of that.
On a $450 quarterly bill, that could save roughly $600–800 a year. Kew ranks 32nd 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 Kew 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 Kew
Large period and postwar family homes on generous blocks. Large roofs and high household use often suit a big system with a battery, if trees allow.
Heritage streets
Many Kew streets sit under heritage overlays administered by City of Boroondara. 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.
Shading from established trees
Mature street and garden trees are common in Kew, and shade costs more output than roof direction does. We check shade on the site visit, including the low winter sun, and use optimisers or microinverters where a few panels can't avoid it. Score your roof.
Older switchboards
A lot of Kew 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 Kew
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 Kew: questions
How much power do solar panels make in Kew?
Each kW of north-facing panels in Kew makes about 1,432 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 86% of that. (PVGIS satellite data.)
Is solar worth it in Kew?
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 Kew?
Many Kew properties are under heritage overlays with City of Boroondara, 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 Kew?
Yes. Kew is about 14 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 Kew home?
Size follows your power use. Most homes paying $350 to $600 a quarter suit 6.6 to 10 kW on single phase. Large roofs and high household use often suit a big system with a battery, if trees allow.
