Solar at home: start with the right questions
Roof conditions, daytime electricity use and future plans matter more than a one-size-fits-all promise of savings.
Read the roof, not just the brochure
EECA identifies roof space, direction, pitch, condition and shade as factors in solar design. A neighbouring tree or an awkward roof shape can affect the installation. Ask an installer to assess the actual property before treating a panel layout in a render as a workable system.
Match generation to your routine
Review when you use electricity, not only the annual total. Solar generates during daylight hours; a household that is usually out then has different needs from one working at home. EECA recommends considering future demand too, such as an electric vehicle or a change in household size.
Separate the options and the costs
A battery can store energy for later use, but adds cost and may lengthen the payback period. Ask for clearly separated panel, inverter, battery and installation prices, together with the assumptions behind any savings estimate. For a new home, confirm whether solar is included, optional or simply being considered.
Questions to take with you
- Has roof suitability and shading been assessed on site?
- Does the estimate reflect your actual electricity use?
- Are a battery, installation and warranties itemised?
