Solar Panel Equation
Solar Panel 12V - built in 5 stages
Constructing a 12V solar panel is easy if you know what to do. There are five main steps. The sequence is important. They determine if you have an easy time building your solar panel. If you follow closely, it will be easier as you continue the construction of your project.
The information here is specific to 12V solar panels or similar low voltage, not the greatest producers solar energy that powers your home. If this is what you want, keep reading ...
Step 1 - The source of solar cells
Can learn new solar cells used for rescue or broken or even that you can do at home.
If you use solar panels for a considerable period of time, you'd better buy new solar cells. It is the most expensive option. However, new solar cells are more efficient and have a longer life. In the long term, the purchase of new cells are probably less expensive than other options.
Used or broken solar cells can be used. But you may have to replace them after a few years because they are made. However, if you want to make a solar panel used for pleasure or broken solar cells will be great. They are certainly not the most professional looking signs around solar, but who cares, we have fun!
You can even make your own solar cells heating plates to form copper oxide Copper, which is a form of semi-conductors. But these facts domestic solar cells are inefficient at best, and produces only microwatts of power per cell.
Step 2 - Soldering the solar cells
Welding photovoltaic cells from twenty to four in the series provides a 12V solar energy. This means that each cell solar product 0.5V. However, there are lots of cells that have not been evaluated to 0.5 V, so it will be good for you to check the specifications before buying.
Have a 12V supply is only part of the equation. Also consider the current output. Only with the voltage correct and sufficient at present, we have enough energy to drive the implementation of your choice.
Step 3 - Glue the cells Solar on a substrate
After joining electric solar cells will stick to a substrate. Many fans prefer to use silicone caulk. But if you're a beginner, you will learn the proper technique for doing so. Otherwise, the components may be stressed out after a short period of time.
Step 4 - Put in a protective case
After photovoltaic cells are mounted on the substrate, which will make a box to keep the substrate. Wood, plastic or metal can be used - each has its unique characteristics.
Personally, I prefer construct the past pregnant. This is because they can be flexible to change our halfway solar panel design, if necessary, without limitation of the box and ready. For large solar panels, you'd better make the first box.
After the box is full, you can continue to the substrate in the area with spots of silicone sealant.
Step 5 - Cover the solar panel box
The last step is to cover your box with a protective clear plastic or glass. This prevents the precipitation and dew damaging solar cells. This is the only part of the solar panel in need of maintenance - cleaning the exterior surface with a soft damp cloth.
After the fifth and final stage, 12V solar panels to generate electricity at your service.

Question involving cost = power x time x cost of 1 kWh?
I usually get the use of this equation, but I do not know how this response addressed: A solar panel offers a large average of 500 watts of power. The cost of 1 kWh is 12.5p. How long does it take to produce the solar panel 1 The book value of electricity. The answer is 16 hours. Can you explain the steps for me. Thank you.
= Total cost (per kWh) (number per kilowatt-hour) or £ 1 = 100 p = [12.5p / (1 kWh)] [number of kWh], so that the number [kWh] = 100 p / p = 8 12.5 kwh. Since energy = power in time, we see that (power) (time) = energy. In addition, since the power and time in hours or (W) (time) = (power) (time) = energy, we find that the p 100 / p = 12.5 8 kwh is just energy. Note that we have not yet used the power given to 500W. The time the formula = energy and power, we have time = 8 kwh / 500w = 8 (1000w) h / 500w-time = 80h / 5 = 16h.
