I have been particularly interested in renewable energy, especially PV, since I was in college.In my opinion, electricity is the ultimate form of energy utilization. As long as there is electricity, almost all devices in our daily lives, such as lights, mobile phones, PCs, microwave ovens, and EVs can be used.If the earth is viewed as a system, solar energy is the only energy input to the earth. All energy on earth, coal, oil, etc., originally came from solar energy.PV can convert solar energy into electricity directly, how amazing.Since graduating from college, I have mainly held three jobs, namely in a PV module factory, a solar inverter factory and an energy storage factory.
