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.

 

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

 250w Polycrystalline Silicon Solar Panels

 

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: when solar panels have served their purpose, what is done with them?
Often they get scrapped out or landfilled. Photovoltaics cannot be refurbished. Solar collectors for heating air or water, could be concievably refitted with new clear covering, new insulation, and new heat exchanger, but unless it was a custom installed system you are trying to refurbish, it is more time economical to construct new ones, or to buy new ones.
Q: I am doing a project on solar energy at the moment and I was just wondering how.

Q: Can solar panels be used in areas with high humidity?
Yes, solar panels can be used in areas with high humidity. While high humidity may affect the efficiency of solar panels to some extent, they can still generate electricity. The performance of solar panels in humid environments can be optimized by using materials that are resistant to moisture and by ensuring proper installation and maintenance.
Q: How long does it take to recoup the investment in solar panels?
The time it takes to recoup the investment in solar panels varies depending on several factors such as the cost of the panels, installation expenses, local energy rates, and available incentives. On average, it typically takes around 6 to 10 years to recoup the initial investment. However, with decreasing panel costs and increasing energy savings, the payback period is continually improving, making solar panels a worthwhile long-term investment for many homeowners and businesses.
Q: How do solar panels affect the property's community image?
Solar panels can positively impact a property's community image by showcasing the owner's commitment to sustainability and environmental responsibility. Their presence can inspire others to adopt renewable energy solutions, leading to a more eco-conscious community perception. Additionally, solar panels can enhance the property's aesthetic appeal, especially when integrated seamlessly into the design.
Q: How much space do solar panels require?
The amount of space required for solar panels can vary depending on factors such as the type and size of the panels, their efficiency, and the energy needs of the system. On average, an average-sized residential solar panel system typically requires around 100-400 square feet of roof space. However, ground-mounted systems can require larger areas, and more efficient panels can generate the same amount of electricity in a smaller space.
Q: And how do you choose the best one for the best price?I saw a 400 watt monocrystalline solar panel
The polycrystalline solar panel has a longer life-span and has a higher efficiency. What this means is that from the energy that 'hits' the solar panel, more is caught and used to convert into electrical energy. A polycrystalline solar panel will have an efficiency of about 4%. The monocrystalline solar panel has a similar efficiency but the cells are prone to sunlight, so the efficiency drops over the years.
Q: I'm trying to charge rechargeable AA batteries with a solar panel. What gauge wire should I use to connect the panel to the batteries? I know I'm not going to have a lot of current going through so the wire size doesn't really matter. Can the wire be too thick thoShould I ugh? Should I use a diode to keep the batteries from overpowering the circuit? If so, what size diode? My panel is 4.8V 50mA. Can I just hook the panel straight into the batteries or do I need something else?
In order: .? Just about any wire will do.? You can handle 50 mA over just about anything, even 28 gauge telephone wire.? Your biggest problems are probably going to be mechanical stress (you want stranded wire instead of solid, to avoid breakage) and dealing with the size of larger wires. 8 gauge speaker wire may be a good optimum. 2.? You need a diode.? If you're charging NiMH or NiCd cells you're going to have about .25 volts/cell; you can charge up to 3 of them in series with a 4.8 volt panel.? The solar panel is a bunch of diodes itself, but they're leaky in the reverse direction; the diode prevents the batteries from discharging themselves back through the panel.? You want a Schottky-barrier diode, because the forward voltage drop is about 0.2 volts instead of 0.7 volts for a regular silicon rectifier.? This gives you maximum current output from your panel.
Q: Can solar panels be installed on tile roofs?
Yes, solar panels can be installed on tile roofs. However, the installation process may require additional precautions and expertise to ensure the integrity of the roof.
Q: Can solar panels generate electricity during a blackout?
No, solar panels cannot generate electricity during a blackout. This is because most solar panel systems are grid-tied and rely on the electricity from the power grid to function. When there is a blackout, the grid-tied solar panels automatically shut off to prevent any electricity from flowing back into the grid, in order to protect utility workers who may be repairing the power lines. However, it is possible to have a backup battery system installed along with the solar panels, which can store excess energy and provide electricity during a blackout.
