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?
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:Please, I want a good definition. :DD
- Solar panel is a battery of solar cells. Solar cell is a device which uses the sun's rays to produce electricity by the photovoltaic effect. The photovoltaic effect involves the creation of a voltage (or a corresponding electric current) in a material upon exposure to electromagnetic radiation. It utilizes the generation of a voltage when radiant energy falls on the boundary between dissimilar substances (as two different semiconductors).
- Q:
- Solar panels can positively impact home resale value by providing potential buyers with energy savings and a reduced carbon footprint. Studies have shown that homes equipped with solar panels tend to sell at a higher price compared to similar homes without them. Additionally, solar panels often increase a home's appeal and marketability, making it more attractive to environmentally-conscious buyers.
- Q:
- Yes, solar panels can be used to power a data center. Solar panels convert sunlight into electricity, which can be used to power various devices and infrastructure, including data centers. By installing a sufficient number of solar panels and using energy storage systems, a data center can be powered entirely or partially by solar energy. This can help reduce reliance on traditional power sources, lower energy costs, and promote environmental sustainability. However, the feasibility and efficiency of using solar panels for powering a data center may depend on factors such as the location, size of the data center, and the availability of sunlight.
- Q:if you know the area of the panel can u calculate for the wattage or voltage of the panel..
- You need to know how many solar cells are in the panel and what is the rated current each cell will produce. This information should be listed on the panel. Each cell will produce from 0.5 to 0.55 volts DC per cell and each cell will produce a current that is dependent on the size of the cell and the type of material the cell is made from. If the cells are connected in series then the voltage of each cell will add together, that is if you have 30 cells connected in series they should generate about 5 to 6.5 volts DC. If each cell generates .2 amps, then you multiply the voltage of 5 volts DC times .2 amps DC equals 8 watts of power. The current of each cell does not add together when you connect the cells in series only the voltage of each cell. If you connect the 30 cells in parallel then the current of each cell adds together but the voltage of each cell does not. That is 0.5 Volts DC times 36 amps equals 8 watts. The power (watts) produced will be the same. See our blog on the products page to see how to connect solar cells in series and in parallel. We also have a PDF file of solar cells and their rated output current sorted by watts per area and their manufacturer.
- Q:i need to cut down on electricity bills, and so i was wondering if someone could give me step-by-step instructions, or websites that have step-by-step instructions on how to build an electricity generating solar panel.
- I have been researching solar electric (photovoltaic) for a while now and find that the up front cost will generally take 0 or more years to pay back. While the life expectancy is 30+ years, giving you 20 years of free energy, most people don't have the initial 20-30,000 start up cost. I've found that wind turbines can be built fairly inexpensively and parts can be easily obtained. The trade off is that wind turbines require maintenance and you also need to be in a reasonably windy area, many municipalities will have restrictions that will impact your ability to put one up as well. The batteries/converters to store/convert your power from DC to AC can also get expensive. Good Luck and thanks for being Earth Friendly and cost conscious! Let's hope that the cost of these products begin to decline as usage increases and new technology develops.
- Q:
- Solar panels can have both positive and negative effects on the aesthetics of a building. On one hand, they can enhance the visual appeal by adding a futuristic and environmentally friendly look. The sleek design of modern solar panels can be seen as an architectural statement, especially when integrated seamlessly into the building's design. On the other hand, some people may find the appearance of solar panels unattractive or incongruent with the building's overall design. However, advancements in solar technology are continually improving the aesthetics of panels, making them more appealing to a wider range of individuals. Ultimately, the impact on the aesthetics of a building depends on personal preferences and the specific design and placement of the solar panels.
- Q:
- Solar panels have a positive impact on the environment as they produce clean and renewable energy, reducing the need for fossil fuels. They help decrease greenhouse gas emissions, air pollution, and water usage associated with traditional energy sources. However, the production and disposal of solar panels can have some environmental impact, including the use of certain materials and energy during manufacturing. Overall, their benefits outweigh the potential drawbacks.
- Q:I'm about to buy one but I don't really know which one is best for my home.
- Talk okorder has good info. What state are you in?
- Q:
- Yes, solar panels can be used to power a sports stadium. By installing a sufficient number of solar panels on the stadium's roof or surrounding areas, the captured solar energy can be converted into electricity to power various systems within the stadium, including lighting, heating, ventilation, and other electrical equipment. This can reduce the reliance on traditional energy sources and provide a more sustainable and environmentally friendly solution for powering sports stadiums.
- Q:
- Solar panels can actually help extend the lifespan of a roof by providing an additional layer of protection from the elements. They act as a shield, preventing direct exposure of the roof to rain, snow, and hail. However, regular maintenance is still necessary to ensure the panels are clean and functioning optimally, as any debris buildup or damage to the panels could indirectly affect the roof.
