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.
GENERAL INFORMATION
The installation of PV modules requires a great degree of skill and should only be performed by a qualified licensed professional, including licensed contractors and licensed electricians. Please be aware that there is a serious risk of various types of injury occurring during the installation including the risk of electric shock. All CUSTOMER modules are equipped with a permanently attached junction terminal box that will accept variety of wiring applications or with a special cable assembly for ease of installation, and they do not require assembly.
COMPONENTS
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?

TILT ANGLE
The title angle of the PV module is the measured between the PV module and a horizontal ground surface. The PV module generates the maximum output power when it faces the sun directly.
For the standalone systems with a battery where the PV modules are attached to a permanent structure , the tile angle of the PV modules should be determined to optimize the performance when the sunlight is the scarcest. In general, if the electric power generation is adequate when the sunlight is the scarcest, then the angle chosen should be adequate during the rest of the year. For grid-connected installations where the PV modules are attached to a permanent structure, it is recommended to tilt the PV module at the angle equal to the latitude of the installation site so that the power generation from the PV module will be optimum throughout the year.
- Q: I have 2 solar panels one is 5 watts 2 volts .2 amps or -The other is 50 watts 2 volts 2.6 amps or-Can I ...and what is the best way to hook them togeather to increase my amps being put back to my battery ?? I would be hooking them up to a 7 amp 00 watt charge controllerThe panels are rated 2 volt but the specs say they will produce more whennot connected to charge controllerPlease advise and should I even bother with the smaller panel ?
- You should probably ask this in the electronics section.
- Q: i am wanting to build a small tiny house running 3-4 2 volt 5 watt light bulbs for a lighting source and using a Koolatron Fun Kool 26 Quart 2V Portable Mini Fridge This cooler consumes 4.5 amps at 2 volts. The conversion is: 4.5 amps (X) times 2 volts (=) equals 54 watts. and i want a solar system that will have back up for 2 days with the lights on for probly 5-6 hours a day so theirs no room for error
- you silly ! with Solar there is always room for error . you have to build it in to your numbers . solar is full of errors . So you should plan on producing at 3 times what you expect you will need . then you have enough .
- Q: What does it take to install the solar panel? Cable wires to power source or fuse box? Anything else?How does the cable wires stay on the solar panel?
- How does the cable wires stay on the solar panel? With wire retention clips (4 per module) that are used to wrap the wire on the underside of the module frame. The home run cables to the transition box (converts between types of wire with no electrical transformation occuring) or combiner box (joins multiple source circuits in parallel, with the positives fused for safety) are usually tied along the racking system components, and with conduit sections used as needed. Racking is another big part of the installation. Don't just make your own homemade wooden rack, as these will weather away to nothing very easily, and cause great failures. GET a professionally designed metal racking system. PV modules are EXPENSIVE. Don't let the racking system cause them to break. It also requires the inverter, if you intend it to connect to the main electric service. If using multiple inverters, you need an AC combining panelboard to join them prior to entering the main electric service. Otherwise, you need to think about how else you might be using them. If you are charging batteries, you need a charge controller.
- Q: Can solar panels be installed on a sports stadium?
- Yes, solar panels can be installed on a sports stadium.
- Q: Composition and function of solar panels
- In addition to the quality of EVA itself, the components of the manufacturers of laminated technology is also very large, such as EVA glue degree is not up to standard, EVA and tempered glass, backplane bonding strength is not enough, will cause EVA early aging, affecting components
- Q: Any recommendations for companies? Any things to look out for?
- It depends upon how you look at things. If you are looking for a decent return on investment, or a business decision, it is probably very unwise. In most cases people would see a far better return in upgrading insulation in ceilings, walls, and windows to much better insulation than they currently have, followed by proper resizing heating and air conditioning to smaller unit size to fit their lesser need as a result of the insulation. The heat an air conditioning units should be the highest efficiency available. The return on the above can make a positive and economic investment in many cases. If you have done the above first, and have money to spend and do not care about the return on it, then you can play with solar or wind. However, typical cost of generation of solar and wind energy is about $0.22 / KWH and you can purchase from utility at about $0.0/ KWH including generation and distribution so this is not all that prudent.
- Q: I thought that I had a fairly good understanding of watt's law, but i'm starting to doubt myself.If I have a load of 4500watts at 240 volts, how many watts of solar panels do I need, if the solar panels are at 2v?Yes, Yes... I have a charge controller, batteries, etc...So the way I looked at this at first:watts = volts * amps For the load4500 = 240 * xx would be 8.75aFor the power source (each solar panel)00 = 2 * xx would be 8.3a8.75 / 8.3 = 2.25, rounded up = 3So... based on that I came to the conclusion that I needed 3 solar panels...But... then I was thinking. Does it work that way?Or do I need 4500 / 00 = 45, aka 45 solar panels?In other words...If I have a 2v power source, how many watts do I need to drive a load of 4500w at 240v?ThanksMatt
- The easy way is to just use the power values. You need 4500W. Each solar panel delivers 00W (from a value in your working). Therefore you need 4500/00 = 45 solar panels. This is a crude calculation, ignoring efficiencies, voltage conversion losses and losses due to internal resistance. You would probably need quite a few more than 45 panels. ___________________________ I'll explain how to do the calculation your way. Each solar panel delivers 00W with a voltage of 2V. So the current is 00/2 = 8.333A. Each solar panel delivers 8.333A at 2V. But you require 8.75A at 240V panel delivers 00W. To get 4500W, you need: 8.75/8.333 = 2.25 times more panels to increase the current AND 240/2 = 20 times more panels to increase the voltage. So overall you need 2.25 x 20 = 45 panels. Of course if the power output of each solar panel is not 00W, you have to change the above calculation accordingly.
- Q: Hoping to find instruction, materials list and hardware needed to construct solar panels myself, how many and make it happen instead of talking about it
- If you think that a solar storm is going to knock out most power utilities in that time, what makes you think that your solar panels will not be affected as well? The cost to even come close to light up half your house will be prohibitive and will take at least a decade or 2 to just break even on your original costs. May want to do a little more research on your 202 storms. If you are concerned about the power going out for a while, then you better check at what else may happen.
- Q: Can solar panels be used for charging laptops or smartphones?
- Yes, solar panels can be used for charging laptops or smartphones. By converting sunlight into electricity, solar panels can provide a sustainable and renewable source of power to charge electronic devices.
- Q: Ok so my electric bill is through the roof because of the air conditioner (mini-split). Is there any kinds solar panel I can buy at a store and install it myself? Do I need any skills? Which brand? blah...blah...blah...
- You can attempt to install your own solar panels...just do the homework first! I suggest looking at ways to decrease your overall energy consumption first even if installing solar panels. Doing this will save on the amount of panels you need. Have included a reference that may be of use to you.
