Few people will argue about the desirability of having a car that can drive by gas stations and leave no pollution behind, yet solar power cars have not become very popular. The solar cells are very fragile, they generate a small amount of power and motors powered in solar power cars produce too small an amount of horsepower to make them efficient.
For roughly twenty years the yearly race of solar electricity automobiles runs in Australia from Darwin to Adelaide, a trip of about 1,877 miles at max speed of nearly 62 MPH. These races are a part of the World Solar Challenge with groups from many major varsities and company ventures competing. In the first race of solar electricity automobiles in 1987, top speed was just 42 miles an hour and is run to market research into solar powered autos.
There are not many efficient applications of solar electricity vehicles in use, however some golfing carts are run by solar electricity and they can recharge while sitting in the daylight annually. Part of the difficulty is that the amount of solar cells attached to the auto is restricted by the autos size and the motors they operate are typically between 2 and 5 h.p.. Batteries are still to heavy to be ready to receive enough power to bump their weight as well as the weight of the auto and operator.
Batteries Work Same As Fuel Tank
Batteries inside solar energy automobiles serve much the same purpose as a gas tank on convention automobiles. While lead-acid batteries are far more efficient and better to connect, the power to weight proportion makes them a disinclined choice in solar energy autos. Nickle-cadmium, lithium ion and lithium cadmium batteries have a better range, but are tougher to include into the automobiles electric system. Usually solar energy automobiles need between eighty and 170 volts to operate.
While cross-breed autos using gas or diesel engines are growing in appreciation, cross-breed bicycles using solar electricity and human peddle power have also grown latterly. Having the ability to get a vehicle moving by human energy before adding power from solar electricity is now being viewed as a likelihood for solar energy vehicles. Except, rather than using human power, stored battery-operated motors are being used.
As there are no established designs for solar electricity autos many designers are centered exactly on reduced drag. This has led to development of many autos bearing a robust similarity to aeroplanes.
