It is expected that the annual capacity of 2012 will be up to 30 million for wafer, 300MWp for solar cells, 1000MW for solar modules and 2 million for solar applications. 

 

INTRODUCTION

This installation Manual contains essential information for the electrical and mechanical installation that your must know before installing CUSTOMER PV modules. This also contains safety information you need to be familiar with .All the information described in this manual are the intellectual property of CNBM and based on the technologies and experiences that have been acquired and accumulated in the long history of CUSTOMER. This document does not constitute a warranty, expressed or implied.

CUSTOMER does not assume responsibility and expressly disclaims liability for loss, damage, or expense arising out of in anyway connected with installation, operation, use or maintenance of the PV modules. No responsibility is assumed by CUSTOMER for any infringement of patents or other rights of third parties that may result from use of PV module.

CUSTOMER reserves the right to make changes to the product, specifications or installation manual without prior notice.

 

SITE SELECTION

In most applications, the PV modules should be installed in location where there is no shading throughout the year. In the Northern Hemisphere, The PV modules should typically face south, and in the Southern Hemisphere, the PV modules should typically face north. Please make sure that there are no obstruction in the surroundings of the site of installation. Take proper steps in order to maintain reliability and safety, in case the PV modules are used in areas such as: Heavy snow areas/Extremely code areas/ Strong wind areas/Installation over, or near, water/ Areas where installations are prone to salt water damage (*)/Small islands or desert areas.(*)

If you are planning to use the PV modules where the salt water damage may be possible consult with CNBM local agent first to determine an appropriate installation method, or to determine whether the installation is possible?

 

WIRING

To ensure proper system operation to maintain your warranty, observe the correct cable connection polarity(Figures 1&2) when connecting the modules to a battery or to other modules. If not connected correctly, the bypass diode could be destroyed.

PV modules can be wired in series to increase voltage. Connect wires from the positive terminal of one module to the negative of the next module. Figure shows modules connected in series .

Q:solar panel design question?
Because we and the trees are trying to solve a different problem. We want electricity, a tree wants light (and some heat) for photosynthesis. In getting the electricity we use Silicon for solar panels. (Sometimes Gallium Arsenide). And we exploit the same thing in Silicon that allows them to be computer chips. The fact that they conduct differently when voltage is applied. But for a solar panel that is done essentially in reverse. We GET a voltage difference (electricity) from shoving energy through it. Look up junction bias on google or yahoo for explanation. But the DESIGN problem is: You have to couple these panels together the right way - according to their bias. You can't string them up willy nilly. There is a pattern. And when one breaks in this pattern. (I mean when the actual panel cracks, which they do easily as they are brittle). It can change the overall bias. This can make even be worse than if it was removed, it can actually fight against the working ones. The efficiency is there in arranging them like a tree, but the practicality of maintenance would be daunting.
Q:how can i build a solar panel?
Have okorder.com . This can surely guide anyone!
Q:Why aren't electronics made with solar panels?
Yes your right, solar panels (photovoltics) could be used to make electricity for small electronics. Right now solar cells are on many calculators, and even flashlight. But the problem is the lenght of time the cells take to charge the device, verses the power demand. I don;t think the size of the panels, and the amount of time needed to charge the device are practical. One think I have been thinking is that every one should have a photovoltaic panel to charge a battery. Then, use the battery to charge cell phones, MP3 palyers. The panel and the battery could be about the 8 x inches, and could sit in window, or on a dash board to get charged, then used in doors over night to charge devices.
Q:Powering an air conditioner via solar panels?
There are solar air conditioners. They don't use electricity. Most anyway. The number of photovoltaic panels you would need to run a standard electric air conditioner would cover most of the homes on the block. Read about heat pumps, Thermal storage, swamp coolers, solar heating to get an idea of what is practical. Most solar systems are hybrid because of clouds and nightfall. The best solar homes are designed from the ground up. With plenty of insulation, the right size and orientation of windows and collectors. Putting solar on an existing structure is going to be a misfit half donkey job unless you are very lucky.
Q:What equation would i need to determine the raise in temperature of water going through a thermal solar panel?
solar panels don't store energy, they only generate it. If you want to store energy you need a battery bank of some kind to get you through the night and anytime the sun isn't shining. If you have a little extra in the budget you might look at a geothermal system for your home's heating and cooling needs. They're highly efficient systems and you can supplement however you like. Whatever you do, though I hope you have a good building envelope in place already. Solar panels are cool, but if you have a leaky house, you're still not getting the best out of your panels. Do the more mundane stuff first. Insulation, windows, and weather-tight doors.

Q:How many solar panels have ah?
The area of ​​the solar cell chip is not exactly the same as the area of ​​the solar package panel, because some solar panels, although large, single solar wafer arrangement gap is wide, so that the solar panel power is not necessarily high. 2, in general, the power of solar panels is the bigger the better, so that the current generated in the sun, and soon it will be filled with built-in battery.

Q:Buying Solar Panels...?
Are you aware of the complications that go along with installing a solar system? A solar panel might put out about 00 watts at 24 volts DC. What would you use it for. The typical solar system has a lot of panels connected in series. The output is connected to an inverter to make 20-240 volts AC. This is connected to the power grid if it is to be used. Also if it is felt that the system should provide power during an electrical outage, there will be batteries. How big would you wan it to be? Mine has forty panels with two inverters. It supplies all the electricity for the house, with some left over to supplement my gas heat. Read the Q and A in the Search box at the upper right of this page, by searching for solar panel. Also study all you can get your hands on.
