Frequently Asked Questions
Solar PV & Battery Savings Calculator
- How long does a domestic solar installation take?
- A typical residential system (10 to 16 panels) is mounted and wired in 1 to 2 days, with scaffold assembly usually taking place the day before.
- Is a battery storage unit worth the additional cost?
- Adding a 5kWh–10kWh battery increases self-consumption from roughly 35% to over 75%, insulating you against rising peak evening grid tariffs.
