Suryakalash: Hybrid Solar Water Purifier

Affordable • Sustainable • Safe Drinking Water for All

Suryakalash is a low-cost, hybrid solar water purification system designed to provide safe drinking water using sunlight as the primary energy source. It is ideal for homes, rural areas, schools, and emergency conditions where clean water access is limited.

How It Works

1. Solar Thermal Pasteurization (Primary Stage)

  • Uses concentrated solar heating + thermal storage

  • Raises water temperature to ~65°C, enough to destroy harmful pathogens

  • Works without battery power

  • Completely renewable and eco-friendly

2. UV-C LED Sterilization (Backup Stage)

  • When sunlight is low, an LDR sensor detects reduced brightness

  • System automatically activates a low-power UV-C LED for final disinfection

  • Microcontroller and sensors run on a small rechargeable Li-ion battery

  • Ensures water safety even during cloudy days or evenings

3. Safety First

  • UV-C placed inside a sealed chamber

  • Manual kill switch for emergency shut-off

  • Ensures protection from UV light exposure

Why We Need Funding

Your contribution will help us:

  • Purchase high-quality components to build our final safe prototype

  • Develop affordable units that cost only ₹1500–₹2000 per piece

  • Begin a small-scale student-led startup to create low-cost water purifiers

  • Reach communities that struggle with access to safe drinking water

  • Create a sustainable business model that supports skill development for students

Component List (Estimated Cost ₹1500–₹2000)
