We are exploiting our environment by emitting CO2. Car is one of the sources in association with industry. Recently car giant tested solar-powered car. As the price of solar cells decreases in a significant way the demand for solar cells increases which attracts car manufacturer. Time has arrived that fossil fuel canot be source of electricity or energy. Every day we are wasting lot of clean energy from the sun and that only can be utilized by solar cell presently. We are worried about our global warming but a bit negligenty about availability.

In cooperation with Sharp, Toyota is testing electric Prius models equipped with solar cells. Market maturity is in the distance. Promoted by the Japanese government, Toyota is equipping its Prius vehicles with solar cells supplied by Sharp. The cells cover the hood, the roof and the rear of the vehicles. Toyota has chosen the maximum propagation to determine how much solar energy can be collected at maximum. As Reuters reports, the accumulated energy is supplied directly to the vehicle batteries, so that the Prius can even be charged while driving or while parked. In addition, the test cars have additional batteries in the trunk. According to Toyota, such an equipped Prius could collect energy for up to 56 additional kilometers on a sunny day, covering common daily distances of an average user. However, the energy yield falls significantly in cloudy weather, but also in high heat. Solar cells have become increasingly thinner in recent years and thus become more flexible. Thus, the cells installed in the Prius measure only three millimeters. Nevertheless, the structure on the vehicle components is about one centimeter, because the solar cells from the vehicle body decoupled, quasi-packed to protect them from destruction.

The efficiency of the cells used should be 34 percent. Overall, the system delivers, according to Toyota 860 watts rated power. In order for the test series to develop marketable products, the entire package would have to become much lighter and, above all, much cheaper, says Satoshi Shizuka, Toyota’s responsible engineer for the project. He estimates the commercial availability as “years away“. If we can get a solar impact after one year, we are lucky enough.
