Key Takeaways
- You have real choices. Community solar, small wind, solar thermal hot water, home batteries, virtual power plants (VPPs) and green power plans all reduce reliance on grid electricity without traditional rooftop panels.
- Renters and apartments are covered. Community solar and green power plans let people who can’t install panels still access renewable energy.
- Community solar is scaling fast — Australia’s Community Solar Banks program is designed to help lower bills for up to 25,000 households.
- Efficiency upgrades pay off first. A heat-pump hot water system uses roughly 30% of the energy of a conventional electric hot water system, cutting bills before you generate a single watt.
- Match the tech to your use case: unsuitable roof, rural block, renter, or budget-conscious buyer — each has a best-fit alternative.
Why Look for an Alternative to Solar Panels?
The main reasons Australians seek alternatives to rooftop solar are an unsuitable roof (shading, orientation, age or heritage restrictions), renting rather than owning, high upfront costs, or living in an apartment without roof access. In these cases, community solar, green power plans, home batteries, solar thermal and small wind can each deliver renewable energy or lower bills without traditional panels.
It also helps to separate two different questions. An “alternative to solar panels” can mean a different renewable technology (like wind or solar thermal), or a different way to access solar energy (like community solar or a VPP) without owning panels on your own roof. This guide covers both angles so you can find the right fit.
Quick Comparison: Solar Panel Alternatives at a Glance
The best low-cost alternatives to solar panels for most Australian homes are green power plans and community solar (no upfront cost, ideal for renters), while home batteries, solar thermal hot water and heat pumps deliver the biggest long-term bill savings for owner-occupiers.
Alternative | Typical Upfront Cost | Best For | Suits Renters? | Main Benefit |
Community / shared solar | $0 (subscription) | Renters, apartments, unsuitable roofs | Yes | Solar access with no install |
Green power / GreenPower plan | $0 (bill premium) | Renters, quick switch | Yes | 100% renewable electricity |
Home battery + VPP | High | Owner-occupiers, existing solar | Rarely | Store energy, sell to grid |
Solar thermal hot water | Medium | Homes with high hot-water use | No | Cuts water-heating bills |
Heat-pump hot water | Medium | Most homes, cooler climates | Sometimes | ~70% less energy for hot water |
Small / residential wind | High | Rural, windy, off-grid blocks | No | Generates when solar can’t |
1. Community Solar and Shared Solar
Community solar lets you subscribe to a share of a larger, off-site solar installation and receive credits on your electricity bill — without installing anything on your own roof. It is one of the best alternatives for renters, apartment residents and homes with unsuitable roofs.
In Australia, shared solar is being rolled out through targeted programs. The Community Solar Banks program is intended to provide shared solar systems that help lower electricity costs for up to 25,000 households (energy.gov.au). Apartment-focused schemes are gaining traction too: in New South Wales, the Solar for Apartment Residents program had approved 33 applications since opening in February 2025, setting up more than 1,100 kW of rooftop solar for over 534 apartments, with estimated savings of up to $600 a year per apartment (energy.gov.au).
2. Green Power and GreenPower Plans
A green power plan is the fastest and cheapest alternative for renters or anyone who can’t install hardware: you keep your existing connection but your retailer sources accredited renewable energy on your behalf, usually for a small premium per kilowatt-hour.
It won’t lower your consumption, but it lets you support renewable generation immediately with no capital outlay and no landlord permission required. For many households this is a sensible first step while they weigh up bigger investments like batteries or a move to a solar-friendly home.
3. Home Batteries and Virtual Power Plants (VPPs)
A home battery stores energy for use when you need it, and a virtual power plant (VPP) links thousands of home batteries so they can support the grid and earn owners credits. Batteries pair best with existing solar, but they also let you store cheap off-peak grid power and cut peak-time costs.
VPPs are one of the fastest-growing ways Australians are getting more value from stored energy. Community-scale storage is emerging too: in the Illawarra region, 13 new community batteries were installed to support 600 households, with participating households estimated to save up to $400 a year (energy.gov.au). If you want to compare current hardware, see our guide to the best solar batteries in Australia, and if you’re not ready for a battery yet, read how to store excess solar energy without a battery.

4. Solar Thermal and Heat-Pump Hot Water
Solar thermal systems use the sun’s heat (not electricity) to warm water, while heat-pump systems extract warmth from the air very efficiently. Both slash one of the biggest costs in an Australian home — water heating — and are a strong alternative to solar panels if your goal is lower bills rather than electricity generation.
The savings are significant because water heating is such a large slice of energy use. Hot water is the largest source of greenhouse gas emissions in an average Australian home, accounting for up to 25%, and about 25% of average household energy use (energy.gov.au). Switching to a heat pump makes a big dent: heat pump water heaters use about 30% of the energy of a conventional electric hot water system (energy.gov.au).
5. High-Efficiency Heating and Cooling
Reducing how much energy you use is often cheaper than generating your own — and reverse-cycle air conditioners are the standout upgrade. They move heat rather than create it, delivering far more output than the electricity they consume.
Reverse-cycle air conditioners sold in Australia range from 300% to 600% efficient, meaning they can deliver 3 to 6 times as much heating or cooling energy as the electrical energy they consume (energy.gov.au). Combined with insulation and draught-proofing, efficiency upgrades cut your bills first and shrink the size (and cost) of any renewable system you install later.
6. Small Wind and Residential Micro-Generation
Small wind turbines generate power when the wind blows — including at night and in winter when solar output falls — making them a useful complement or alternative for rural, coastal and off-grid properties with consistent wind and enough space.
Power your home with the sunshine above and the wind at your back! Ditch the grid or off-grid and embrace clean energy independence with a customised solar + wind + battery storage system.

7. Emerging Options: Solar Windows and Building-Integrated Solar
Building-integrated photovoltaics (BIPV) — including solar windows, solar tiles and solar facades — generate electricity from surfaces other than a traditional roof array, making them appealing for architecturally sensitive homes and unsuitable roofs.
These technologies are maturing and can be an attractive option where appearance matters or roof space is limited. To understand where the tech is heading, read our explainer on solar windows and the future of building-integrated solar.
Which Alternative Is Right for You?
Match the option to your situation: renters and apartments should start with green power plans or community solar; unsuitable roofs suit community solar, solar thermal or BIPV; rural blocks can consider small wind; and owner-occupiers chasing the biggest savings should prioritise efficiency upgrades and batteries.
- Renters: Green power plans and community solar — no install, no landlord approval.
- Unsuitable or shaded roof: Community solar, solar thermal hot water, or building-integrated solar.
- Budget-focused: Efficiency upgrades and heat-pump hot water deliver the fastest payback.
- Rural / off-grid: Small wind combined with batteries — see our off-grid system maintenance tips.
- Owner-occupiers with solar: Add a home battery and join a VPP.

Frequently Asked Questions
What is the cheapest alternative to solar panels in Australia?
The cheapest alternatives are green power plans and community solar, both of which have no upfront hardware cost. Green power adds a small premium to your bill for accredited renewable electricity, while community solar lets you subscribe to an off-site array and earn bill credits.
Can renters use alternatives to solar panels?
Yes. Renters can switch to a green power plan or join a community solar program without installing anything or needing landlord approval. Apartment-specific schemes are also growing, such as NSW’s Solar for Apartment Residents program.
Is community solar available in Australia?
Yes. Community solar is expanding through government-backed programs. Australia’s Community Solar Banks program is intended to provide shared solar to help lower costs for up to 25,000 households (energy.gov.au).
What can I do if my roof is unsuitable for solar panels?
If your roof is shaded, wrongly oriented or heritage-listed, consider community solar, solar thermal hot water, or building-integrated options like solar windows and tiles. Efficiency upgrades and a green power plan can also cut bills and emissions immediately.
Is solar thermal better than rooftop solar panels?
They do different jobs. Solar thermal heats water using the sun and is very efficient for water heating, while solar panels generate electricity. If cutting hot-water bills is your priority, solar thermal or a heat pump often delivers faster savings than a small PV system.
Are small wind turbines a good alternative for homes?
Small wind works best on rural, coastal or off-grid properties with steady wind and open space. It’s rarely practical on suburban blocks, but it can complement solar and batteries where conditions are right, generating power at night and in winter.
