welos

WELOS presents itself as an integrated rooftop appliance that turns a single urban footprint into a power-and-water system, combining solar generation, wind capture, and rainwater recovery into one coordinated unit rather than three separate installations. The site opens with a scroll-driven cinematic sequence showing the physical device on a Dubai rooftop, cycling through four stages — expose, generate, recover, and coordinate — that visually walk through how the same footprint captures sun, wind, and rain and routes them through one resilient loop.

Past the intro, the site frames the core pitch: one system, three resources, smarter resilience. It positions WELOS as the response to an environment where rooftops sit underused while solar potential is abundant, wind is intermittent but present, and rainfall is scarce but valuable when captured rather than lost to runoff and evaporation. The site backs this with regional figures: roughly 2,285 kWh/m² of annual solar irradiance, wind speeds in the 1.1–4.5 m/s range, annual precipitation between about 95 and 130 mm, and a modeled soiling-loss range of 0.29–12.7%, establishing why coordinating these three inputs — rather than treating them as separate systems — makes sense in an arid, sun-dominant city.

The architecture section breaks the product into four coordinated layers: a monocrystalline photovoltaic surface with MPPT tracking and thermal/soiling monitoring for primary daytime generation; a vertical-axis wind turbine supplying complementary power; a hydrological layer that catches, first-flushes, filters, and stores rainwater; and an edge-intelligence control layer built on ESP32/STM32 hardware that senses conditions and makes routing decisions. A resource-flow diagram shows how each input takes its own physical path — sun through the PV array and MPPT to the DC bus, home loads, and battery; rain through the apron, first-flush diversion, filtration, and storage; wind through the turbine, generator, and rectifier to the same DC bus — before a single control system decides where power and water actually go.

The site's standout feature is its self-cleaning logic: rather than cleaning panels on a fixed schedule, the controller estimates expected photovoltaic output from irradiance and temperature, compares it against measured output to compute a soiling index, and only triggers an automated rinse — using the system's own stored, non-potable rainwater — once soiling exceeds roughly 15%, water reserves exceed 20%, and wind is calm enough (under 5 m/s) for a safe wash. This condition-based maintenance approach is framed as smarter than blanket cleaning schedules that either clean too early or let performance degrade too long.

Further down, the site outlines a path from concept to proof: a scaled prototype (100–200W solar, 50–100W helical VAWT, 12V/24Ah LiFePO₄ storage, UV-C water treatment, and the same ESP32/STM32 control unit) meant to validate the underlying intelligence without pretending to power an entire building. The site closes on its unifying thesis — that WELOS isn't three separate systems bolted together, but one coordinated resource loop turning an underused rooftop into responsive infrastructure — before inviting visitors to scroll back to the top or explore the live prototype further.
