Short answer: with the same 920 Wp of panels, both make the same electricity, about 683 kWh a year vertical in London [calc]. Octopus is £149 cheaper and includes delivery; Zendure's SolarFlow 800 has two MPPT inputs and a 1,200 W panel input. Cheaper than both: City Plumbing's 950 Wp kit at £456.

What actually differs
- Price: £650 against £799: the £149 gap is about 1.7 years of savings at our default settings [calc].
- Two MPPT inputs (Zendure): each panel is tracked separately, which helps when the two panels face different ways or one is shaded. Octopus says its Fox ESS microinverter also manages each panel independently.
- Delivery: Octopus aims to deliver by the end of November on a pallet, kerbside. Zendure was on a 50-day pre-sale, with only the floor-bracket version available.
- Brackets: both include mounting hardware; check the version matches your balcony, wall or garden.
