A method of upgrades a conventional electric powered bicycle over to Solar-PoweredElectrical Bicycle that is powered by an electric motor which gets its supply from photovoltaic (PV) panels. The PV panels must be mounted and installed at the bicycle without compromising riding comfort ability. The method employs a small electric motor that are easily connected and separated for ease of transport. A solar collector is connected to the rechargeable batteries for collecting solar energy and converting such energy to electrical power that is delivered to the rechargeable batteries for recharging thereof. A rechargeable battery is operable connected to DC motor for providing electrical power to drive the motor.
There are several problems that occur during upgrades a conventional electric poweredbicycle to Solar-Powered Electrical Bicycle. The specifications of photovoltaic (PV) panelsmust be sufficient to generate the electric motor same as a conventional electric poweredbicycle. The suitable connection of solar cells, rechargeable battery and DC electric motorwith bicycle needed to make sure this project accomplish with more optimum energy use. Theelectric motor must to support the weight and size of the bicycle, size of solar panel andcondition of the road surface.
Solar cells (really called “photovoltaic” or “photoelectric” cells) that convert lightdirectly into electricity, bypassing thermodynamic cycles and mechanical generators. PV stands for photo (light) and voltaic (electricity), whereby sunlight photons free electrons fromcommon silicon.
A photovoltaic module is composed of individual PV cells. This crystalline-silicon module has an aluminium frame and glass on the front. In the field of photovoltaic, a photovoltaic module is a packaged interconnected assembly of photovoltaic cells, also knownas solar cells. An installation of photovoltaic modules or panels is known as a photovoltaic array or a solar panel. A photovoltaic installation typically includes an array of photovoltaic modules or panels, an inverter, batteries (for off grid) and interconnection wiring.
Electric Powered Bicycle
An electric powered bicycle carries batteries or fuel cells that deliver electric power to a motor that is coupled to either wheel. In most electric bicycles the rider can choose to use muscle power to deliver all, part, or none of the propulsion power required to maintain his or her adopted travel speed. Some models even sense your pedal pressure and command the motor to deliver more power whenever you pedal hard.
Many electric powered bicycles are specifically design and build for travel. Average travel speed, when compared to pedalled-only bicycles, can be increased by 8 to 10km/h (5 to 6 mph) above the speed an average person could travel by pedalling.
