Making a DIY Solar Power Generation Device

In my previous blog, I wrote about decorating your own home with your own hands, washing tools DIY car, etc. -DIY household sewage recycling device, DIY household sewage recycling device, circulating water humidification device, DIY household anti-theft alarm device, laundry washing device DIY household tableware, DIY car cooking appliance, what I want to share with you today is a DIY solar power generation device!

1. Buy equipment

1. Polysilicon solar circuit board, 200 Wp, 130 cm long, 70 cm wide, 15 kg, 650 yuan,

2. battery Two pieces, 120ah, 900 yuan

3. Charge and discharge overload protector, 80 yuan

4. 1kw inverter, 24v to 220v, 400 yuan,

5. Voltage display meterbattery, 10 yuan.

6. 100 yuan for 50 meters of wire, 2 yuan for a box of clips, 4 yuan for plugs, 4 yuan for two plugs

7.

< p>8. Mains to charger 24 V 60 A, 120 yuan

9. 2 plugs, 2 yuan, a 220 V relay, 10 yuan and a socket, 5 yuan. A total of 17 yuan

II. Installation

1. Attach the solar panel bracket to the sunny wall, which costs 100 yuan.

2. solar circuit board with the bracket is tilted towards the sun at an angle of 30 degrees.

3. Connection

1. Place the two batteries side by side and connect the positive and negative terminals.

2. Arrange the inner wires and secure them with clips. Since the house has been renovated, the wiring must be run along the baseboards to hide them.

3. Connect the interior wires to the outlet, plug in the timer switch, and set the switch to open at 6:00 and close at 6:30.

4. Set the charging timeConnect the positive and negative poles of the battery, the positive and negative poles of the inverter, the positive and negative poles of the overload protector, the positive and negative poles of the voltage display meter, and the positive and negative poles. solar panels to the positive and negative poles of the battery respectively.

5. Connect the contacts and plugs of the relay, connect the main power plug to the solar timer, connect the common power plug to the mains timer, and set the mains timer to start at 6am. Morning. Close at 6:30 and connect both normally open and normally closed ends to the outlet. , if you don't understand here, please refer to my blog post on Yelianzhongxin's blog; “Can a relay be used as a dual power automatic transfer switch? » 》

6. Insert the plug of the rice cooker (500 W) into the socketat the relay

After the above 6 steps, the home solar power generation system is completed. the next day, the electric rice cooker will automatically cook rice at 7 o'clock, stir-fry something, eat for a while, finish washing and go to work.

Of course, the battery still has some power and can be used as a night or bathroom light, so I won't go into detail here.

It should be noted that both items 8 and 9 above can be saved, but it may cause inconvenience in your life, because solar energy cannot provide energy when it There are continuous clouds, and the equipment itself must also consume some of the energy. When the undervoltage is too low (generally considered to be less than 22.2 V), power must be replenished to avoid damage to the battery and shorten its life. solar energy cannotfunction. The relay acts as a transfer switch and automatically connects to AC power to continue operating the charged rice cooker.

How to use solar energy to make small inventions

1. To prepare the materials, you must first prepare the following materials: solar panels, PVC pipes, tees, elbows, internal joints. , glue, insulated pipes, paint, electronic thermometers, old iron sheets, plastic foam, old sponges, etc.

2. First find solid, good quality wood and simply make a 2.1X1.2m frame. Then transform the T-pipe into a hot exhaust pipe of the same type as the water heater device. Then pour foam over the frame and paint the foam and the old iron sheet black.

3. Connect the shelf made of solar panels to the thermal tube. Note that the pipe must be installed with an insulating tube. If youhave an electronic thermometer, you can install an electronic thermometer for easier detection. of the water temperature.

4. Install the vertical post behind the support and cardboard. The height and inclination of this vertical pole can be adjusted as desired. Then the glass tube is filled with water and the glass tube is first sealed and then placed on the rack. Then adjust the pole, observe the direct angle of the sun and adjust the pole to the corresponding height. The larger the area exposed to the sun, the better.

5. When adjusting the concave arc of the pole, you should do it on the roof of a building exposed to the sun or in a high place. The reflection of the sun focuses on the glass tube. better effect. Then simply attach the bracket.

6. After a while, the homemade solar water heater can use the principle of cold water flowing and hot water floating to check the tewater temperature. Then wait a while, then check the amount of hot water obtained. You can also fill the homemade solar water heater with an appropriate amount of water according to the weather of the day and connect the pipe from the water outlet to the place where hot water is needed.

How do elementary school students make simple solar water heaters?

Homemade solar cooker

1. Find a concave reflective bowl on a large flashlight and use rigid foam plastic or wood to cut a cylinder about 4 cm wide long and 1 in diameter. should simply fit firmly into the round hole of the reflecting bowl.

2. Drill a thin hole transversely in one end of the cylinder, insert a wire with a diameter equal to the diameter of the hole, then bend both ends of the exposed wire 90°. , leaving 5 cm on each side.

3. Insert the cylinder into the round hole of the bowl ref.licking, then insert both ends of the wire into a piece of foam plastic or a wooden base plate.

4. Sharpen both ends of a thin bamboo stick, insert one end into the cylinder in the center of the reflecting bowl, and insert a small piece of potato into the other end. Place the device in the sun, with the reflecting bowl facing under the sun.

5. Then, patiently adjust the length of the bamboo stick so that the inserted potato is exactly in the focus of the light.

It won't be long before the potatoes are baked in the sun and become fragrant.

Solar fan

Requires hardware, solar motor, good friends, 6 screws, wires, iron sheets (with holes, 2 pieces), rechargeable batteries and fans.

1. Parallel connection, solar panels, each panel has a positive pole and a negative pole, just connect the positive pole of one tonegative pole of the other, that's it.

>2, Fix the solar panels on the wooden board;

3. Find a way to erect the wooden plank. I used assembly toys to do this. It is best to set the elevation angle of the solar panel. according to the position of the sun;

4. Place the motor on the teaching aid and secure it;

5. Make the switch and check the transmission line

.

6. Connect the line.

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 amountwater request.

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.
