Top Sustainable Charging Solutions
1. Solar-Powered Charging Stations (Most Popular & Effective)
• Public or home stations with rooftop/standalone solar panels.
• Many real-world examples (e.g., in the US and Europe) use solar + battery storage for 24/7 availability.
• Benefits: Zero emissions, low running cost, off-grid capable. One or two panels can often meet daily needs for multiple bikes. 
2. Portable/Foldable Solar Panels
• Lightweight panels you attach to the bike, backpack, or set up anywhere. Great for trekking, commuting, or emergencies in Kathmandu valley or hilly areas.
3. Integrated Solar on E-Bikes
• Small panels on the frame, rack, or panniers that trickle-charge while riding or parked.
4. Smart/Grid-Tied with Renewables
• Charge during sunny/off-peak hours or pair with home solar systems. Use second-life EV batteries for storage.
5. Other Green Options
• Kinetic (pedal/regenerative) + solar hybrids.
• Community battery swapping stations powered by solar.
