The aim of the project is to design a scooter with renewable solar energy. Solar Bike aims to be a small research and development business that develops renewable technology and helps everyone start riding electric bicycles around rather than using their cars. We firmly believe that using solar powered bicycles is one of the best methods of reducing our dependence on fossil fuels and minimizing environmental damage caused by carbon dioxide emissions.
A solar panel is a flat rectangular shaped device, typically somewhere between the size of a radiator and the size of a door, made up of many individual photovoltaic energy collectors called solar cells covered with a sheet of glass on its surface. The cells, each of which is about the size of a palm of an adult, are usually octagonal in shape and colored bluish black. Similar to the cells in a battery, the cells inside a solar panel are designed to generate electricity; but where a battery's cells make electricity from chemicals, a solar panel's cells produce power by capturing sunlight instead. They are sometimes called photovoltaic cells because they use sunlight ("photo" comes from the Greek word for light) to make electricity (the word "voltaic" is a reference to electricity pioneer Alessandro Volta).
In this project we are going to use solar panel and DC hub motor. The voltage generated by the solar panel is stored in battery (48V/20AH) through charging circuit. From the battery, power will be supplied to the DC hub motor (48V/200W) through accelerator followed by gate switch. The purpose of gate switch is when break is applied then automatically it opens the connection between motor and accelerometer.
The wheel hub motor is an electric motor that is incorporated into the hub of...

The electricity generated by the solar cell panel is stored during the day with the help of storage batteries which give us only DC i.e, Direct Current. But in order to operate our devices we need alternating current. Therefore we need to initiate the conversion from convert before using any appliance using inverter.
Periodic Monitoring and Maintenance is required.
A drastic environmental change cannot be tolerated by the equipment.
The entire process of manufacture is still very expensive as silver is used for interconnection of these cells in the solar panel, which is a very expensive metal.
A practical problem linked with the use of solar cell panels is regarding the storage of electricity general by them.
The conversion of DC to AC uses inverter before using any appliance and thus it increases the cost of such solar panels as the sources of electricity.
Solar cells directly convert photons from the sun into electricity (Wikipedia). Solar cells that convert both solar and non-solar light are called photovoltaic cells (Wikipedia 2006). They are made of semi conducting materials, most often silicon (Aldous 2006). The simplest photovoltaic cells power watches and calculators while larger, more complex systems can add to the power grid and provide power for homes.
To deal with the problems of Fossil Fuels that are exhaustible and not environmental friendly, an electrical vehicle that runs on solar energy have been designed. Conventional vehicles use combustion engines that burn a fuel/petrol or diesel in cars and boats, and in kerosene planes (“How Do Solar Vehicles Work”). However, solar vehicles uses energy that is stored in a battery during and after it charges from a solar panel; uses electric motors for driving and solar cells to generate the electricity (Yogesh Sunil). They use batteries to make sure there is a source of electricity available, even after sunset or on rainy days (“How Do Solar Vehicles Work”).
The bicycle powered generator represents a climax of the engineering education. The results far exceed our expectations with a power source that could provide ample amounts of energy. The bicycle generator is capable of outputting about 1000 watts hour a day. Some design improvements for future production would include overcharging prevention in the charging of the appliance, i.e. controlling the amount of power induced during the mechanical process. Depending on the need of the power, the overall design could be changed to handle varying loads much more effectively, in the future.
Preview: Today I will discuss the potential that solar power has to become this country’s main supply of energy and the latest research that can make solar power more efficient and cost effective. I will also present the environmental benefits that come with using solar power over other and more harmful forms of energy.
Most of the people in our modern day society are beginning to realize that fossil fuels are becoming more rare and are damage our planet, this creates the need for a more sustainable form of energy. Solar energy is one of them and is becoming more and more important and will hopefully soon replace this obsolete technology.
Solar energy products can range from solar panels to cell phone charges, and everything in between. Solar energy is becoming a popular way to fuel homes throughout the United States. All over the country, people are covering their rooftops with solar panels, heating their pools with solar energy, and even turn on the lights in their homes with solar energy. Solar power is quickly becoming America’s most popular form o...
The solar panel, is able to work through solar modules using light energy, or photons, from the sun to generate electricity through the photovoltaic effect. The photovoltaic effect is the creation of voltage or electric current in a material upon exposure to light. A research conducted by Imperial College, London has improved a way of making solar panels much more efficient by studding the light-receiving semiconductor surface with aluminum nano-cylinders which are fairly similar to the ridges o...
Rooftop solar is comprised of solar panels, an inverter, and a meter connection to the electric grid. Solar panels are made from different types of silicon that produce direct current when exposed to sunlight. The direct current from solar panels is routed via metallic wires into an inverter which converts direct current to alternating current, also known as DC to AC conversion (Solarworld, 2014). The output of the inverter is tied into an electric panel. This is where your electric meter gets involved with tracking kilowatt hours produced by your solar panels before they are fed back into the electric grid (Zipp, 2013).
As the increase in the consumption of energy gradually increases per year, the government needs to take measures in opting to renewable energy sources, preferably solar energy because of its decreasing price, versatility, and its abundant main source of energy.
From the early times of human beings, trying to find ways to harness the suns energy for their daily lives , we have come long ways since the first solar panels now we have other ways to create energy but those aren’t safe they’re dangerous and hazardous to the environment. The future begins with change and we can’t do that if we’re still doing the same things to, burning fossil fuels and power plants are the main sources of today’s pollution. Solar panels are a great thing for this time in age, harnessing the sun’s rays for energy pollutant free air.
Solar panels are systems that generated heat or electricity by using the energy to be carried ray of the sun. Solar energy panels absorbs the sun’s energy with the aid of dark surfaces located inside panels. After obtained heat, water is heated by transferring water by solar energy panel.
Solar power is energy efficient, what is meant by that is that solar power cannot ever run out as long as it is installed properly. Solar power cells is a source of electrical energy that converts a powerful source of energy such as the sun into electricity, using it’s energy to create electrical currents within the solar panel. Solar panels produce electricity using technology called “Solar Photovoltaic (PV)”.
For example, people may charge their electric cars in the morning with the sunlight, and during the night the electric cars will work by saving the power from the morning; as a result, solar power runs for a long time, and people may do their work without doing any problems for the environment. Furthermore, solar energy does not use any equipment to work such as wires or cords unlike other sources like wind energy. For instance, solar power can be at the roof of the house without using any equipment, and without taking any space. On the other hand, Louwen, Sark, Schropp, Turkenburg, and Faaij (2015) stress that solar cells need to replace the material that is used or decrease the amount of the equipment used such as silver and indium since they are used in silicon cells. This might negatively impact the environment and the production cost (p. 1407). Overall, solar energy can be used as a renewable energy to reduce the pollution and protect the environment from the harmful gasses, and can be used without access to power
Photovoltaic cells directly convert solar energy into electrical energy through a chemical action taking place in solar cells. They act on the principle of photo-voltaic effect, which develops an emf on absorption of ionizing radiation from sun. It is the most popular technology when it comes to converting solar energy to electric energy. Because of its design, it can even be installed on building roofs making it very popular among
At our new house, we have two stand alone pedestals with six 170W panels on each pedestal, making for 2040W or 2kW solar system. According to Mr. Solar.com, “this type of energy production, known as the Photovoltaic Effect, is achieved by solar panels converting sunlight into energy. Solar panels are made up of several individual solar cells, composed of layers of silicon, phosphorous (which provides the negative charge), and boron (which provides the positive charge). Solar panels absorb the sunlight’s photons and by doing so initiate an electric current, producing electrons. The resulting energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their atomic orbits and released into an electric field generated by the solar cells, which then pull these free electrons into a DC or directional current.” This electricity then proceeds to a mechanical room beneath our house to a charge controller, which regulates the amount of energy sent to our 24V batteries to be stored. From these batteries, the electricity goes to an inverter, which then changes the DC to AC or alternating current in order to use our modern electrical appliances and gadgets.
