When Will We Be Able To Drive Energy-Efficient And Environmentally Friendly Solar Cars

In the 21st century, the development of human science and technology seems to be on the highway, but energy resources are also gradually dissipating. Solar energy has also become a hot topic in the new century. The convenience brought by solar energy is also increasingly entering people's lives.

In the tech world, solar panels are also getting more and more attention. They have great potential to become low-cost renewable energy generation technology. Organic solar cells are composed of monocrystalline silicon, glass and polycrystalline silicon wafers. These three materials are processed by economical methods such as printing or coating, and solar panels can convert solar light energy into electrical energy and output DC storage. into the battery. Then someone raised the question: "Why not install solar panels on electric vehicles? Doesn't that not only save resources but also improve efficiency?"

As far as the current photovoltaic technology is concerned, there is still a long way to go to realize solar electric vehicles. The biggest reason is that the conversion rate of solar cells is too low, resulting in low charging efficiency. Let's assume that a pure electric car runs 8 kilometers with 1 kWh of electricity, and only urban commuting is counted. If it runs 40 kilometers a day, it needs 5 kWh of electricity. However, the efficiency of 200-watt polysilicon solar panels is less than 1/3 in daily use.

Although there are many difficulties, with the progress and development of photovoltaic technology, solar cars are getting closer and closer to us. Perhaps in the not-too-distant future, mature photovoltaic technology cars will meet us unexpectedly

Our company is mainly specialized in solar power remote control systems. We can build large PV power plant and we also supply home use and small business use solar power systems. Save carbon emission, let's start with PV power generation systems.
