Introduction
Imagine a world where your home becomes a mini power plant, quietly chipping away at the dominance of coal and fossil fuels. That's not a distant dream—it's happening right now, especially in Australia. As the Smart Energy Council's chief noted in one of his final speeches, the bottom-up energy revolution led by rooftop solar and home batteries has 'changed the dial in a very significant way.' This guide shows you exactly how to join that revolution, step by step. By the end, you'll see how your personal energy choices can act like kryptonite against big coal, one sunbeam and stored electron at a time.
What You Need
- Basic knowledge of your home's energy usage (past electricity bills).
- Financial resources or access to financing/grants (e.g., solar rebates, battery subsidies).
- Property suitability – a roof with good sun exposure (north- or west-facing in the southern hemisphere).
- Permits and approvals – check local council rules, and ensure your electrical system can handle solar.
- Time and commitment – installation takes a day or two, and ongoing monitoring is easy but valuable.
- A trusted installer – look for Clean Energy Council accredited professionals.
- Optional: energy monitoring app, smart home system, or time-of-use tariff plan.
Step-by-Step Guide
Step 1: Understand Your Role in the Energy Revolution
Big coal relies on centralised power plants and steady demand. When millions of homes generate their own electricity, demand drops, and coal plants become less profitable. This is the 'kryptonite' effect. Start by reading about Australia's rooftop solar boom—how it has already slashed peak demand and forced coal plants to close early. Knowledge is the first step: every kilowatt-hour you self-generate is a kilowatt-hour not bought from fossil fuels.
Step 2: Assess Your Home's Solar Potential
Check your roof’s orientation, shading, and structural condition. Use online tools like Google's Project Sunroof or local solar maps. A north-facing roof (in Australia) with little shade is ideal. Also review your electricity bills: what’s your average daily consumption? This helps size your system. For a typical home, a 6–10 kW solar panel array plus a 10–13 kWh battery can cover most needs.
Step 3: Choose the Right Solar Panels and Inverter
Not all panels are equal. Look for high-efficiency monocrystalline panels with at least 25-year performance warranties. Inverters (string or microinverters) convert DC to AC. Microinverters work better if your roof has partial shade. Compare brands like Jinko, Trina, or LG for panels, and Fronius or Enphase for inverters. Get quotes from 3–5 installers and ask about net metering policies in your area—these determine how much you're paid for excess solar fed back to the grid.
Step 4: Add a Home Battery System
Batteries store daytime solar for evening use, dramatically increasing self-consumption and reducing reliance on coal-powered grid electricity. Popular options include the Tesla Powerwall, LG Chem RESU, or BYD Battery-Box. Consider capacity (usable kWh) and warranty (10 years typical). A battery also provides backup during outages. Financially, it may take 7–10 years to pay off, but the environmental impact is immediate. Many Australian states offer interest-free loans or rebates for batteries—check your state's scheme.

Hire a Clean Energy Council accredited installer. They'll mount panels, install inverter and battery, connect to your switchboard, and arrange grid connection with your retailer. The process takes 1–3 days. After installation, you'll receive a compliance certificate. Then you can start generating! Use the monitoring app to track production and consumption in real time. Aim to shift heavy loads (like washing machines) to sunny hours.
Step 6: Optimise Usage and Scale Up
To maximise your 'kryptonite' effect, run appliances during peak sun hours, charge your EV from solar, and consider time-of-use tariffs that reward daytime use. Some utilities offer virtual power plant programs where they aggregate your battery with others to support the grid—this can earn you extra income and further displace coal. Over time, you can add more panels or a second battery as your needs grow.
Step 7: Advocate for System Change
The bottom-up revolution is not just about individual installations. Share your experience with neighbours, write to your local MP supporting renewable policies, and join community energy groups. As more people adopt solar+battery, the political pressure on coal increases. The Smart Energy Council's chief emphasised that this grassroots action has 'changed the dial'—you can be part of that change.
Tips for Success
- Start small but think big. Even a 3 kW system makes a difference. You can expand later.
- Compare multiple quotes — price varies widely. Don't just go with the cheapest; check reviews and warranty terms.
- Battery-first vs solar-first? If you can afford both, do both. But if not, install solar first, then add battery within a year.
- Monitor your system — anomalies can mean lost generation. Most apps alert you if output drops.
- Keep your roof clean — dust and leaves reduce efficiency. A twice-yearly clean is enough in most areas.
- Stay informed about policy changes—feed-in tariffs, renewable certificates, and net metering rules evolve. Join forums like SolarQuotes or Whirlpool.
- Enjoy the independence. Every sunny day, you're not just saving money—you're taking power away from coal. That's your kryptonite.
