Solar data,
on a living map.

Solar irradiance, weather, GPS — from every tower in your network to one live map. Whether you run a solar field, a research lab, or a single rooftop sensor, open your data from the office, the lab, or your phone in the field.

A tower at every horizon

Solar-grade pyranometers, weather sensors, and GPS at every site — packaged in IP-rated towers built to outlast the rain, the dust, and the desert sun.

One SIM, an entire network

Sensor towers across your site link back to the master over long-range radio. One cellular uplink for the whole network — not one per tower.

Open from anywhere

Office, lab, or your phone in the field — your private map opens in any browser. No app, no install, no excuses.

About LvWinSys

End-to-end solar telemetry — sensor to dashboard.

We design the wireless sensor towers, the firmware that runs them, and the cloud platform you use to read them — every wire, every byte, every reading goes through a system we own and can fix. No cobbled-together stack from three vendors.

Built in Singapore. Field-tested across solar farms, university research sites, and rooftop installations in tropical and continental climates. The hardware is IP-rated and battery+solar powered. The cloud is built for 24/7 uptime with proper alerting, data exports, OTA firmware updates, and a public REST API for researchers who want raw data in Python or MATLAB.

Solar operators get live monitoring and threshold alerts. Researchers get clean, citable data with a documented API. Site owners get hardware that survives rain, dust, and the desert sun — without per-tower SIM cards, because one master uplinks for an entire site over LoRa.
