Are solar panels on the roof of a car good?

Introduction Is solar panel on car roof good or bad? 1. Low conversion rate and insufficient power. Gallium arsenide thin film power generation technology can expose thousands of times to direct sunlight. Reality has changed.

Are solar panels on the roof of a car good?

Not good

1. Low conversion rate and insufficient power

The most advanced gallium arsenide thin film power generation technology, with a thousand times direct sunlight, the ideal conversion rate is 31 .6%, but in reality the conversion rate is only around 20%. Assuming that the car solar panel covers an area of ​​6 square meters, the weather is sunny, the solar power is 1 kW/square meter, and the solar exposure time is 5 hours, about 6 degrees of electricity can be obtained. Currently, electric vehicles consume 15 kilowatt hours of electricity per 100 kilometers. You can run up to 40 kilometers per day.

This is calculated to the highest standards. Half of the actual irradiation area of ​​the solar panel is good. In addition to the dark clouds passing in the sky, half of the irradiation energy is roughlythe same. If you lower the conversion rate, the data is less than 10 kilometers. Clearly undernourished.

2. High cost and low performance/price ratio

Thin film solar cells have a power of about 175W per square meter, a weight of 3.5kg and a price of RMB 1,395. The entire vehicle costs 8,370 yuan based on 6 square meters. At the same time, the weight of the vehicle will be increased by at least 21 kg. It's a 10 kilometer journey every day. It's not as good as buying a few lithium batteries, but the price/performance ratio is really low.

3. High maintenance costs, affecting vehicle safety.

GaAs batteries have the characteristics of plasticity, long life and repairability. But today, the cost of production is high and it is difficult to popularize it. Dings and dents in cars are inevitable and repairing solar panels is expensive. Ifpost-installation maintenance is not in place, it can easily fall off, affecting the driving safety of the car.

4. Invisible pollution, gallium is a heavy metal

Solar energy itself is pollution-free, and the power generation process of gallium arsenide thin film power generation panels used is also pollution. -free. Finished gallium arsenide is also non-toxic, but the arsenic it contains during the synthesis process is highly toxic and gallium is also a heavy metal. Being so close every day, invisible pollution has no way of hiding. There is no plan to recycle damaged solar panels, which inevitably leads to pollution.

Suzhou Wuri New Energy Technology Co., Ltd.

According to the Chinese supplier network, Suzhou Wuri New Energy Technology Co., Ltd. can recycle second-hand photovoltaic panel inverters to Luohe. The company's main products: solar panel recycling, photovoltaic component recycling, solar panel recycling and photovoltaic panel recycling.
