1. The first step is to connect the battery sheets in series with copper tape. A battery chip is equivalent to a small power generation unit, which can generate a current of 0.5V and 5.2A. By connecting a number of battery chips in series with copper strips, it is possible to obtain more energy production.
2. Then the battery parts must be sealed and isolated from air, otherwise they will gradually decompose until the generated power reaches zero. Therefore, the second step is to use tempered glass, EVA and backplate. After heating and vacuuming, the battery wafers can be sealed between the glass and the backplate.
3. However, tempered glass is not durable enough and is easily damaged, especially at the corners. Therefore, the third step is to place aluminum frames around it to protect it.
After the above three steps, the solar panel is produced.
How to make a handmade solar water heater
Materials: cans, pigmented foam, reflective materials (CDs, mirrors, if not available you can use foil) cans (preferably iron)
Preparation method:
1. Paint the box black.
2. Paint the foam black and glue it to the box.
3. Place the can in the box and adjust the angle so that it is perpendicular to the sunlight.
4. Put reflective materials on the cans.
How do elementary school students make simple solar water heaters?
According to the principle of solar water heater, the steps are as follows:
1. Firstly, prepare the required materials, such as copper pipes, wooden boards, screws. , glass plates, etc., then put the copper. The tube spool is fixed on theplank of wood.
2. Then use the previously prepared wooden planks to make a frame, and install the wooden plank on which the copper pipe was previously fixed.
3. Install a small faucet at the end of the copper pipe for easy access, a handle is installed on the top of the wooden frame for easy operation.
4. A piece of transparent glass is installed on the outermost surface, which will not affect the use and also protect the copper pipe.
5. These copper pipes are all painted black, which will absorb heat better under the sun.
Use a drink can and spray it with black paint. Put it in the sun, it is the simplest and most primitive solar water heater.
Method 1: Use a drink can and spray it with black paint. Placed under the sun, it is the simplest and most primitive solar water heater.
Method 2: 1. Fill a plastic bottle (preferably a beverage bottle) with an appropriate amount of water.
2. Prepare some mirrors.
3. Place mirrors around the plastic bottles and place them in the sun to heat the water using the reflection principle.
The solar water heater is a heater that converts solar energy into thermal energy, thereby transforming water at low temperatures. Heated to high temperatures to meet people's use of hot water in life and production.
