You can buy degraded drum sheets online. If possible, obtain some tin-plated copper strips and use a soldering iron to connect the battery sheets in series (note that the back of the battery sheet is the positive electrode). and the front is the negative electrode. The positive and negative electrode ribbons cannot contact each other), so the wire from the back of the battery is the positive DC pole and the wire from the front of the battery is the negative DC. , it is already an energy production device. If you want this power generation device to last longer, you need to insulate the battery from air and have a certain mechanical strength. Currently, conventional components must be laminated with EVA backplane. and glass, which is absolutely not allowed in households. At best, it can only be sealed with resin. Of course, this may not be feasy to achieve for households. Also tell us, let me tell you, the current working voltage of 8". Polycrystalline cells are 0.5V per day. You need to consider the voltage of the charging equipment to decide the number of cells to use.
Solar energy
Solar energy refers to thermal radiation energy from the sun (see the three modes of thermal energy transmission: radiation), which is mainly used to generate electricity or provide energy for water heaters in modern times
From the earth, it mainly relies on the thermal radiation energy provided by. the sun Since ancient times, humans have also known how to use sunlight to dry objects and use it as a method of making food, such as making salt and drying salted fish. rare. Solar energyre has become an important part of human energy consumption and continues to develop in two ways: Photothermal conversion and photoelectric conversion are an emerging renewable energy source, which also includes. solar energy on earth. Wind power, chemical power, water power, etc.
