cool beauty When we see the clear water that sprays from our belly and creates pure ozone. Behind the cool beauty is using wasted electrical energy uselessly which in fact Considered extremely inappropriate.

If we had to buy more than 4 baht per unit of electricity to just pump the fountain to make it glisten beautifully. Seems like a waste of energy and a waste of money. And especially if you want to turn on the fountain day and night. to create a beautiful atmosphere for oneself or customers who already have a favor. Think about how much electricity bills per month will increase.
So if we try to choose another energy to replace the electricity from the electricity transmission line that must be purchased for use And that energy must be abundant, sufficient, self-produced and without any additional costs. Of course, there is no better energy. “Solar Energy”
A solar cell system is the production of electrical energy from the sun. There is enough everywhere for everyone. When the sun hits the light A chemical reaction will take place to convert that energy. into electrical energy and can be used to create fountains In the DC power system, which is derived from the solar cell system like this, the solar fountain system project was born. so that we can open the fountain Without having to pay money to buy electricity for the Electricity Authority again
principles and reasons
This project will change the fountain machine system. Originally used electricity from normal electricity transmission lines. in an alternating current system which will change to be used in all DC power systems in order to use solar energy through the solar cell system
Such a solar cell system can use the same set of equipment But it is effective in generating electricity in both direct current and DC directly from the solar panel. And can be powered by batteries for renewable energy when the sun is gone.
objective
solar fountain machine It can work without the need for any power source other than solar energy. which will be designed to be able to be used in many systems Or maybe build a system with a mix of power supply. Or a hybrid system (Hybrid System) to achieve the use of energy that complements each other. In addition, the beautiful, cool fountain creates a continuous atmosphere all the time as well.
project goals
To raise awareness of the energy crisis and build knowledge Understanding of sustainable alternative energy Resulting in an awareness of the search and creation of renewable energy. Know how to use natural energy that does not cause an impact on the environment. transformed into electrical energy to benefit Including saving costs that were wasted in vain. and increase skills in knowledge of electrical systems
Materials used in project implementation
- Solar panel size 20W 1 panel
- DC fountain pump 1 set
- 1 battery charge controller
- 1 battery
- The cable is insulated.
project implementation steps
- Design a circuit to supply electrical energy from solar cells. to the fountain machine
- Experiment with solar panels receiving sunlight. and testing the charging power into the battery through the charge controller
- Check the power level in the battery. and test supplying electricity to the fountain machine
- Follow up on initial performance as well.
method
20W solar panel front and back which we will connect the wires from the connection point In order to send electrical energy from the solar panel. Enter the power management process of the battery controller.
The connection point is located at the back of the solar panel. The lid must be opened by sliding down. You can see the connection points for the positive (+) and negative (-) terminals.
at the connection point The positive (+) and negative (-) terminals are clearly marked. and when we strip off the insulation We will see 2 wires, red and black. According to the international standard of direct current (DC) wiring phase, red is the positive (+) pole and black is the negative (-) pole.
Then insert the cable into the box. Unscrew the cable clamp and pass the cable through the cable clamp. Then connect the wires to the positive (+) and negative (-) poles correctly. We can choose to connect the wires tightly in 2 ways:
- Connect the wires by tightening the nut.
- Connecting wires using a soldering iron
Wiring completed. The most important thing in connecting wires is tightness. May cause sparks and subsequent heat. Therefore, if in the case that we choose to use a knot connection We’ll need to make sure the wires are securely secured enough. Or if you are unsure, you should also choose a way to connect the wires with a soldering iron.
