Solar guides and advice
Practical answers to the questions we are asked most — on panels, batteries, EV chargers, costs, and installation.
Solar Panels
- How Solar Works
A clear explanation of how solar panels convert sunlight into electricity for your home.
- Types of Solar Panels
Monocrystalline, polycrystalline, and thin-film solar panels compared — which is right for your roof?
- What Affects Solar Output
Roof angle, orientation, shading, and panel temperature all affect how much your solar system generates.
- How Many Panels Do I Need
Work out the right number of solar panels for your home based on energy use and available roof space.
- Solar Panel Lifespan
Solar panels typically last 25–30 years. Here is what to expect from each component over the system lifetime.
Battery Storage
