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.
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?

- Q:Is it possible to store energy from solar panels for night?

- Q:How do solar panels affect roof aesthetics?
- Solar panels can have both positive and negative impacts on roof aesthetics. On one hand, solar panels can enhance the visual appeal of a roof by adding a modern and eco-friendly element. They can also create a sleek and streamlined look when installed properly. However, some people may find solar panels to be visually intrusive or out of place, especially if they do not blend well with the overall architectural design of the building. Ultimately, the impact on roof aesthetics depends on personal preferences and the design and placement of the solar panels.
- Q:Can solar panels be installed on a sports stadium?
- Yes, solar panels can be installed on a sports stadium.
- Q:Can solar panels be used in combination with wind turbines?
- Yes, solar panels can be used in combination with wind turbines. This combination is known as a hybrid renewable energy system. It allows for a more reliable and efficient generation of electricity as the two sources complement each other. Solar panels generate electricity during the day when there is abundant sunlight, while wind turbines generate electricity when there is sufficient wind. By combining these two sources, the system can produce electricity continuously, regardless of the time of day or weather conditions.
- Q:Can solar panels be installed on a warehouse or industrial facility?
- Yes, solar panels can be installed on a warehouse or industrial facility. In fact, these types of large commercial buildings often have spacious rooftops that are ideal for hosting solar panels. Installing solar panels on warehouses and industrial facilities can help reduce electricity costs, generate clean energy, and contribute to sustainability efforts.
- Q:can anyone help me? i was thinking of installing solar panels to cut bills but would it be a waste considering its gonna need a circulating pump running almost 24/7 (which will use electricity) and even still will only provide me with quot;warmwater? also would it be possible to install the solar panels for the sole purpose of providing sufficient power to run electric heaters instead of using gas/oil? this way allowing me to have a warm house without the expensive bills. brobably talking about running 7 heaters/electric radiators.
- Are you thinking of installing electric solar panels or thermal solar panels or both? It would be better to install electric solar panels for electric heating. You can run 7 heaters as long as you do the calculations for the number of panels need for the daylight hours, and the required battery bank to supply the required power.
- Q:Which kit did you use?How easy was it to build? How much did it cost to build the panels?How many kw or watts does it produce?Any other info on the kit or panels you built would be helpful.Thanks!
- sure, but if you don't know what you are doing you could really hurt or kill yourself. Basically you can do whatever you want on your side of the power meter and in the rare occurrence when your solar panels are producing more power that your home is using the meter will run backwards and you will be feeding power to the grid and theoretically reducing your power bill. At the very least you will be using less power from the grid
- Q:Single crystal solar panels and polycrystalline solar panels
- Monocrystalline silicon cells in the laboratory to achieve the conversion efficiency of 24.7%. Ordinary commercial conversion efficiency of 10% -18%. Monocrystalline silicon solar cells because of the production process problems, generally its semi-silicon ingots for the cylindrical into, and then through the slice -> cleaning -> diffusion knot -> remove the dice -> the production of electrodes -> corrosion around -> Reflective film and other workers made of finished products. General monocrystalline silicon solar cells four corners for the fillet. Monocrystalline silicon solar cell thickness is generally 200uM-350uM thick, and now the production trend is to ultra-thin and efficient direction
- Q:Can solar panels be used in areas with high levels of rainfall?
- Yes, solar panels can be used in areas with high levels of rainfall. Rainfall does not necessarily affect the functioning of solar panels as they primarily rely on sunlight to generate electricity. However, it is important to ensure that the solar panels are properly installed and maintained to prevent any water damage or reduced efficiency caused by excessive rain.
- Q:I have created a solar setup in my shed i have 2x.5w solar panels i am hoping to charge my 55ah car battery how long would it take to charge the battery and how many watts could i used a day
- Quite a while. I am assuming you are using 2 volts as your buss power. The small panels were intended as a float charge for batteries to keep them from discharging over a period of time. 3 Watts means only /4 Amp. Normally when I do slow charging of batteries, I am using right around amp, and that takes about a week to bring up a battery that was discharged past 80 percent capacity. When you factor in losses from corrosion, battery self discharge, and loose connections, you will likely want to add more panels. using your 55Amp/hour battery, a amp charger running constant in a perfect world would take 55 hours. Real world, probably closer to 64 to 72 hours. That for simplicity is 5 Watts constant charge power. Now you are using /5 of that with your current setup. so 5 times longer, whichh puts you in the 300 hour range of real world, or 220 hours of perfect world. This time of year, you may have about 8 hours worth of charging light, which puts you at close to a month. Don't fret. If you are using it for lighting in a shed, Power LEDs and tethering some of the inexpensive LED lights to the 2 volt source will give you plenty of light for a very long time, the panels will help some, but you will likely need to put the batteries on a charger, or you can build a gas powered 2 volt generator easily enough. Charge it up only when needed.
