Node 01 is down for maintenance

AI that runs
entirely on sunlight.

SolarNodes serves open models from a micro data center on a mountain ridge. Powered by a solar array, buffered by batteries, cooled by alpine air. No grid. No fossil fuels. Every answer comes straight from daylight.

From sunlight to answer

A pipeline with 
zero carbon emissions.

01

Sunlight hits the array

An array of solar panels track the alpine sun across a south-facing slope.

02

Batteries store the day

A battery bank stores the surplus, smoothing clouds and carrying the cluster clean through the night.

AI served carbon-free

Open source models answer through chat or via an API.

Why solar

The data centers serving today's AI burn power like it's free. It isn't. We think intelligence should cost the planet nothing.

While data centers are the invisible backbone of our digital world, their rapid expansion comes with a heavy environmental and local toll. Carbon emissions remain a primary concern, as these massive facilities consume vast amounts of electricity 24/7, often straining local power grids and relying on fossil fuels to maintain uptime. Beyond their carbon footprint, their immense cooling needs lead to severe resource strain and water contamination; data centers dissipate heat by evaporating millions of gallons of water daily, sometimes discharging chemically treated wastewater back into local ecosystems or depleting precious municipal supplies. 

Furthermore, surrounding communities are increasingly battling infrasound and low-frequency noise pollution generated by massive industrial cooling fans and backup diesel generators. This constant, low-frequency hum can travel for miles, leading to sleep deprivation, anxiety, and a diminished quality of life for nearby residents, turning these digital hubs into material environmental hazards.
