Solar panels installed on the roof of buses in Hong Kong are not used to power the bus itself — they supply auxiliary systems. Here’s why they matter: ✅Powering onboard electronics Solar panels provide energy for interior lighting, display boards, information screens, CCTV systems, and USB charging ports. This reduces the load on the main engine and generator. ✅Supporting ventilation and air conditioning In Hong Kong’s hot and humid climate, the panels can power ventilation when the bus is parked, help maintain cooling systems, and reduce cabin overheating. ✅Fuel savings By sourcing part of the electricity from solar energy, the engine spends less time idling, fuel consumption decreases, and emissions are reduced. ✅Environmental agenda Hong Kong активно integrates green technologies into public transport as part of its decarbonization strategy, helping to cut CO₂ emissions in a densely populated city. #China
