Solar bus

Open-air low-speed electric shuttle sightseeing buses equipped with a solar panel-covered roof are produced in series and are commercially available.

[2] It uses 100% solar power, is equipped with a regenerative braking system and air conditioning and can carry up to 40 persons,[3] 25 of whom are seated.

The Tindo is part of the 98A and 98C bus service (until recently known as the Adelaide Connector) which is offered as free public transport.

[4][5] Within the Chinese government's program for the clean transport sector, China's first solar hybrid buses were put in operation in July 2012 in the city of Qiqihar.

It is claimed that each bus consumes 0.6 to 0.7 kilowatt-hours of electricity per kilometre and can transport up to 100 persons and that the use of solar panels prolongs the batteries' lifetime by 35 per cent.

[7][8] In March 2020, Energy Swaraj — An Essence of Sustainability, a program conducted by All India Council for Technical Education (AICTE) was launched, led by Indian Institute of Technology (IIT) Professor Chetan Singh Solanki.

The Buzz has 2 KW in homemade solar panels on the roof, 40 golf cart batteries, 2 electric motors, and has no tailpipe.

The Solar Buzz is an IntraCity bus approved by the state Public Regulation Commission (#56817) in 2015 and is a commercial daytime private shuttle service with a US$3 Fare, operated by Hot Springs Transit, LLC.

Solar panels are also used for powering electronic devices of the bus such as heating and air conditioning, even in buses with the non-solar-powered engine.

[14] Refitting existing vehicles with photovoltaic panels that feed the original battery with additional electric power has been shown to have the potential for contributing to CO2 emission mitigation and to the reduction of pollution.

The use of buses in public transport implies frequent stops with the opening and closing of doors, which influence the way the energy of the battery is used.
