How does the solar cooking system work without a battery?

Solar panels generate DC electricity directly during the day, which powers a coil heater similar to an induction stove. No battery storage, no LPG, no smoke.

Can it cook on cloudy days?

Cooking is best done during sunny hours since there is no battery backup. On cloudy days, output reduces, so cooking may take longer or need to be timed around available sunlight.

Is Green Filament the patent holder?

No. Green Filament is the authorised manufacturer of this patent-granted technology, not the patent holder.

Who is this system suited for?

Homes, anganwadis, schools and community kitchens looking to cut LPG costs and cooking smoke exposure.

How many units are installed so far?

Over 200 units are running across India.

What is the expected lifespan of the system?

The coil-based design is similar to conventional coil heaters, built for long-term daily use with minimal maintenance.

Firewood dependency, power outages, and unreliable supply chains leave communities without consistent access to clean cooking energy.

How It Works

Simple Three-Step Process

Sunlight in. Hot meals out. No fuel, no emissions, just clean energy from the sun.

STEP 01

Solar Panel

Captures sunlight and converts it to electricity. Six 500Wp solar modules provide ample power for all-day cooking.

STEP 02

Charge Controller

Regulates and optimizes power flow directly from the solar panel to the coil heater ensuring stable, efficient heat output throughout the day.

STEP 03

Coil Heater → Cooking

The 1500W coil heater generates efficient cooking heat compatible with any standard pot. Zero fuel cost. Zero emissions. Zero hassle.
