Product Description:


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.


Solar cell module production process

Line called packaging line components, packaging is the production of solar cells a key step in the packaging process without a good, multi-well battery is also not a good component of production boards. Battery package not only the battery life is guaranteed, but also to enhance the combat strength of the battery. Product quality and high service life is to win can be the key to customer satisfaction, so the quality of components of the package board is very important.

Q:Who made solar panels?
Google would like to be your friend - Try - who invented solar panels and see what turns up.
Q:How do you make a homemade solar panel?
Did okorder.com/ . Possibly this could immediately instruct each and every one!
Q:What does it mean when a solar panel is 50 watts?
Solar okorder.com/
Q:best value solar pv panel ?
For okorder.com . If powering a PC is your only goal, consider replacing the power supply in your PC with one that runs off native 2 volts (like the kind intended for RV's). Then you can avoid the 30% loss of energy in a cheap inverter. I think you will see a significant drop in the price of panels in the next couple years, by the way.
Q:so what do you all think about solar panels? are they worth it?
It okorder.com He has a modest system, and soon will be uploading some useful informaiton on cosntructing smaller solar arrays from individual small cells salvaged from various items. At some point too he will cover converting some items people would not really think of to running on 2 volts that once were 20 VAC items. I know the author.. so I get previews. If you post a question in his comments on some aspect or detail or if something is not real clear, he will try to address them too.
Q:How much money does it cost to make ONE solar panel?
If okorder.com/.. Low-cost crystalline panel manufacturers such as Suntech are believed to have costs in the $.50/watt range today - making it $300 for a 200-watt panel. That doesn't mean that one can buy a panel for that price, of course. If you mean a DIY panel from purchased solar cells, the cost would be closer to $360 for an equivalent-powered panel, not counting the price of the frame, and the labor. A homebuilt panel would not stand up to decades of weather unless one spent even more on the frame. And since such a panel would not have safety certification, it could not legally be connected to the grid in most places. If you meant a water heating panel, please update or post another question - I'm sure people will chime in.
Q:Generator for solar panels....?
There is now a completely portable (and ultra-high efficient) solar power generator which produces up to 800 watts of household electricity on demand when you need it most. News of this solar backup generator (it's the first off-the-grid breakthrough in 50 years) is spreading like wildfire all across the country!
Q:What direction do solar panels usually point?
The general answer is toward the equator, so south when the array is north of the Tropic of Cancer, and north when south of the Tropic of Capricorn. In the equatorial zone, one would often still point towards the equator, but other factors such as wanting the panels to efficiently drain rain and dew come into play. But wait, not so fast. Financial considerations dominate in some areas. When afternoon electricity costs more than morning electricity, it may pay to have panels oriented southwest in the northern hemisphere. Where electricity costs the same all day long, it may pay to orient the panels southeast, to harvest more in the morning, when temperatures are cooler, and the panels are more efficient. For solar hot water, SW is usually optimal in the northern hemisphere, because of higher ambient temperatures, and also the usage pattern of most people using the hot water when they get home in the evening. A local installer that has been around for several years will know what orientation is optimal for your area.
Q:Can I made my own solar panel?
no, not really, they require exotic chemicals and processes. The online outfits that promise to help you build your own are mostly scams. The one I looked at (other answer) seems to just be an assembly guide to put together solar cells into panels. That is fine, but you still have to buy the solar cells, the expensive part. The assembly is just putting them in series/parallel to produce higher voltages and currents. .
Q:How can I adapt an automotive reglator to a solar panel?
solar panels will naturally produce a certain DC voltage which is what your battery needs - the current will vary based on the sun light. You need probably 4V to have some over voltage. So based on your specs look at having at least 4 V but not too much over that (tells you how many panels you need in series) I would have blocking diodes (probably the solar cell has them built in) to insure the battery does not discharge thru the panel.
