Introduction
Power banks have become a very important thing in daily life. The benefits of a power bank can be understood only when the power supply is cut off in some way or when we go somewhere, in other words it is a very important thing when traveling.

| Solar Power Bank Really Works |
But in the present age we are so busy with laptops or mobiles that there is no time to recharge them. And if there is a power cut at that time, we get lost of mind.
Well, if our power bank had been recharged before it was charging. Even possible, yes it would be possible if we had a solar panel in our power bank.If we had solar panels installed in our power bank, we would just put the power bank in the sun and the power bank would be automatically charged.
Yes, a question arises here. Can everyone really charge the solar panel the power bank?
To answer this question we need to know how solar panels work, Types of solar panels how to install solar panels so that solar panels can give their maximum output, irradiation, weather wise output,loss with prevention and some mathematical explanations are required. These will be described one by one below.
Working of solar panels
A solar panel and diode are always the same but solar panels have some differences. At first solar panel made by semiconductor material like germanium silicon.
We know that any passive element contains N-type and P-type material, since a semiconductor device is made of germanium or silicon. Some impurities are mixed in this germanium or silicon semiconductor conductor material.
N - type material impurities called Pentavalent impurities and P-type materials called trivalent impurity. This impurity method is called doping. The impurities in N-type material use phosphorus and P-type material use impurity is boron.
Due to this type of impurity, the number of holes in n-type material increases and positively charged electrons move in p-type metal.A positively charged electron cannot be neutralized with a negative charge because a junction or depletion layer is formed.
We know that the light source is the current of the photon particle and another thing is known that the semiconductor material reaches the conduction band when there is any hit or biasing from outside.So the radiation of the sun on the solar panel starts pushing the posts in the n-type metrorail towards the positive electrons and current can flow through the circuit.
Type of solar panels
Solar panels are 3 types
*Nowadays Monocrystalline cells are very popular for this type of element because of their efficiency and economical view.
Theory
What do you think I need to know? This is because you need to know all the information about the quality of a solar panel power bank when you use it so that you can choose its quality.
Usually when solar panels are installed at home or in the office or anywhere. Then the solar technician has three things that are important: radiation, tilt angle, orientation angle.
By measuring these three things, they can understand that if the solar panel is set in exactly the right place, then the solar panel will be able to give data the highest efficiency output. If a house is facing south, then solar panels should be installed in a place where the sun can cover the solar panels all the time of the day.
If that is not the case then the problem is that we get maximum sunlight from 6am to 3 pm (approx)If this 9 hour solar panel does not get sun then you will lose a few hours. The battery will not be fully charged at that time.
For Generate Maximum Efficiency what is the best position of Solar Power Bank
Now the question is how do we find out these three things Tilt Angle, Orientation and Irradiation. That being said you can say someone is a solar technician or. Or they can try it out themselves. And some mobile apps will solve this problem very easily if their use is known. Mobile apps can tell you how much your solar panel is losing.
Tilt angle
If a solar panel is placed at the point where the perpendicular of a straight line is formed, the tilt angle is what the solar panel makes above the perpendicular.

| Tilt angle |
Orientation angle
When a solar panel can rotate 360 degrees according to the circumference of a sphere, what is the orientation angle according to the circumference of the sphere of that solar panel.
 |
| Orientation |
Irradiation
The amount of sunlight that falls in every 1 square meter area is called irradiation.
Output from various Experiments with solar cells and solar power bank
If we test 50 watt solar panels the maximum open circuit voltage output is 21.10 v at full sunlight and the open circuit current is 1.92. A . Here we find the maximum power output open circuit is by simple formula P=V×I is near about 40.56 Watts.
Here almost 18.88% power loss due to not properly installation. This cell's power rating is huge because it does not use mobile phones or power banks . The power bank's maximum output voltage is 5.2 volt and maximum output current is 2 A so output power is almost 10.3 watts . Maintain this maximum output of 10000 mah charging time approx 5.2 hours .
That is why it is necessary to measure the tilt angle, orientation angle and irradiation. If these three things can be measured properly, then the solar panel will be able to turn on its maximum output. And to charge the power bank, it will take the time written in the calculation.
Weather wise output from Solar panel in Power Bank
Monocrystalline solar panel fluctuation of output is minimum . However, we have tested that the maximum output open circuit voltage does not fluctuate at 8% -10%.
Our test results are at maximum full measured maximum output open circuit voltage is 5.03 volt and current is 2.1 A so power is 10.56 watt . Total charging time is 4.7 hours.When the sky is full of clouds the Maximum open circuit voltage is 4.33 volt and current is 1.7 amp the output power is 7.36 watt. Total charging time is 5.8 hours when 10000 mah power bank is used .
Here we can clearly declare that minimum charging time is 4.7 hours and maximum 5.8 hours is 10,000 mah power bank use.
If you maintain the proper tilt angle, orientation angle and irradiation.
If use Solar Power bank your can save your energy which can use for charging. If 10,000 mah power bank use then you can save 50wh energy consumption.

Alternatively if you not want adjust proper tilt angle , orientation angle and irradiation. the you can buy solar tracking device . This device can helps to generate electricity from sun is maximum . This is helps to automatic adjust position change according sun position. Other words says this is Robot which can help you for charge maximum power from sun light.
Which is available is any online marketing platform. And it can available only 600-1000.
Conclusion
Green power is one of the main sources of energy for the future. And which we should use from now on. We should try to save as much electricity as possible. Different engineers and scientists from different countries are working to use this solar energy in different ways.
