Zendure SolarFlow 800 Pro: Was It Worth It?

The video reviews the Zendure SolarFlow 800 Pro balcony‑mounted solar kit, asking whether the modest‑size system justifies its cost and effort. After months of monitoring, the creator finds that peak‑power spikes are misleading; consistent, plateaued output matters more. Shading from nearby trees and sub‑optimal panel angles cut production, while a 10‑15 % gain was achieved by adjusting tilt to about 30°. Real‑world daily yields ranged from under 1 kWh on bad days to over 4.5 kWh on sunny ones. A striking observation is the 85 % self‑consumption rate, driven by daytime loads such as robot vacuums and charging stations that run exactly when the panels generate. The reviewer notes a day with a 1 kW peak yet only 3.4 kWh produced, versus another day with lower peaks but 4.5 kWh total. The takeaway for owners of small solar installations is to focus on shading mitigation, panel orientation, and load timing—often via Home Assistant automation—rather than chasing headline wattage. Proper data collection turns a modest balcony array into a meaningful grid‑offset tool and a template for distributed, automated energy ecosystems.
