- Coastal Homes
Solar built for life by the sea
Most of the Peninsula sits between Port Phillip Bay and Western Port, so many homes get salty sea air and strong winds. Salt can build up on panels and wear metal parts over time. On coastal jobs we:
- Choose panels that have passed salt mist testing
- Use mounting and fixings rated for coastal conditions
- Check roof fixings for wind on exposed sites
- Recommend a regular clean and check to keep output up

- Holiday Homes
Solar and batteries for holiday homes
Many Peninsula homes are weekenders that sit empty during the week. With feed-in tariffs now only a few cents, most of that weekday solar earns very little. A home battery stores it for when you arrive, and an app lets you check your system from Melbourne.
We install Tesla Powerwall 3, Enphase, Sigenergy and Sungrow batteries and claim the federal Cheaper Home Batteries discount for you.

Often, yes. A battery stores the solar your home makes while it is empty, so you use it when you are there instead of selling it for a few cents. Read what size battery you need.
