Starting points for Cheltenham homeowners
Kingston City Council publishes home-energy and electrification information that local homeowners can use alongside independent solar research. Some individual homes may warrant additional discussion of weather exposure and suitable roof mounting; don't assume every Cheltenham property has the same conditions.
This guide is an introduction to the questions that might apply locally, not a statement that every property in Cheltenham has the same roof or electricity requirements.

Recorded solar activity in postcode 3192
As at 31 August 2026, Clean Energy Regulator records show 2,312 solar installation events and 16.6 MW of recorded rated solar capacity in postcode 3192.
- Recorded installations
- 2,312 installation events
- Recorded capacity
- 16.6 MW
- Average recorded capacity
- 7.2 kW per installation event
- Older recorded cohort
- 26.9% from 2015 or earlier
- 2026 recorded installations
- 106 (provisional)
The CER counts certificate-backed installation events, including new systems, upgrades and stand-alone systems. It is not a count of unique homes. Postcode 3192 may also cover places beyond Cheltenham, so these figures are postcode-level context rather than a statistic about every Cheltenham property. The older-cohort share describes when events were recorded; it does not prove that the original equipment is still on a roof or needs replacement.
Make the most of the roof you have
For an established home, the position of existing roof fittings, potential shading and available roof faces can influence the layout. If your property is particularly weather-exposed, ask your installer to explain the relevant mounting standards, equipment suitability and site-specific design. Roof pitch and location alone aren't enough to forecast your production.
Questions worth asking
- Which roof areas have been checked for shade throughout the year?
- Does the proposed mounting arrangement suit this particular property's exposure?
- What system layout was used to calculate the generation estimate?
Design for the household's actual routine
If your household uses significant electricity after work, consider how its daily routine affects direct solar use and the potential role of storage. If you can move selected appliances into daylight hours, you can explore that possibility with our household builder before comparing quotes.
Questions worth asking
- What proportion of our electricity is used when solar might be generating?
- Which suitable appliances could we schedule earlier in the day?
- What financial assumptions change if we choose solar now and storage later?
Planning an improvement or an addition
If an existing solar system already occupies part of your roof, identify its age, panel layout, inverter model and actual generation before discussing expansion. A suitable upgrade pathway can include retaining, expanding or redesigning equipment, depending on the present installation and connection approvals.
Questions worth asking
- What existing equipment is compatible with the proposed changes?
- Which site or electrical upgrades are included in the proposal?
- What has the relevant distributor approved for this address?
