BEFORE YOUR SITE VISIT

Before you decide

Is this an installation quote?

These are indicative company package prices with the price before VAT, VAT 7% and total shown separately. Batteries are excluded. Our team must check the roof, cabling, supply, equipment and installation scope before quoting. Hybrid packages do not include a battery.

What if most of my electricity use is at night?

Start by checking daylight usage. This tool does not size batteries or assume all generation reduces your bill. Discuss backup power separately with our team.

What should I prepare for a site assessment?

Recent and historical electricity bills, roof photos, main electrical panel photos, site location and peak usage times help us assess the system and work scope.
