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 WARNING
1. Before you attempt to install wire, operate and maintain the PV module, please make sure that you completely understand the information described in this installation manual.
2. Contact with electrically active parts of a PV module such as terminals can result in burns, sparks and lethal shock whether the PV modules is connected or not.
3. PV modules produce electricity when the sufficient sunlight or other sources illuminate the module surface. When the modules are connected in series, voltage id cumulative . When the modules are connected in parallel, current is cumulative. As a result, a large-scale PV system can produce high voltage and current which could present an increased hazard and may cause serious injury or death.
4. Do not connect the PV modules directly to the loads such as motor since the variation of the output power depending on the solar irradiation cause damage for the connected motor.
1:In the case of a blushless motor, the lock function becomes active and the hall IC is most likely to be damaged.
2:In the case of a brush type motor, the coil is most likely to be damaged.

- Q: We want make solar panel for our home use. but we have no any right idea how we can make it. we want to make it with cheap prices.we also want to know the proper size of solar panel.where we can take help about making a solar panel
- How to Make a Solar Panel – Everything You are Going to Need There are several things you’re going to need when making a homemade solar panel, some of the main components include: Solar Cells Wood Plate Soldering Iron Solder Tabbing Don’t worry; special tools are not required for this DIY ‘solar panel’ project, and you will probably have everything you need laying around the garage. Now let’s go over the recommended materials for a basic solar system: Plexiglas Solar Cells Screws Lumber Jones Plug Wire Diode Caulk Silicon Material
- Q: Do solar panels require a backup generator?
- No, solar panels do not require a backup generator. They generate electricity from sunlight, so as long as there is sufficient sunlight, they can provide continuous power without the need for a backup generator.
- Q: i have a 2v 2a solar panel that i want to use to charge a 2v battery .Have found out that i need a charge controller so i don't over charge the battery.I have found a cheep one its 2v but 7a will it still work ?All-so im planing on running a 2v water pump off the battery with a timer,its for watering my garden.Will the timer have to be 2v as well ?any help on this would be greatly appreciated thanks .
- The charger will accept whatever current is necessary from the solar panel up to 7A. It's not like the solar panel will force 2amps into the charger/battery -- the charger will control the current going to the battery. I question whether or not the 2V panel will actually charge the battery, though, because in order to charge a standard lead-acid 2V battery you need to have about 4.5 volts applied to the terminals. Perhaps the charger has a boost circuit -- I don't know without looking at it or knowing the brand/model number, etc. The timer must be 2VDC, but, if you only have a timer that is rated for 20VAC, you can buy a small inverter that will take 2V and supply the necessary 20VAC. An inverter rated for 20 to 50 Watts should be sufficient. These usually cost under US$25. .
- Q: Do solar panels require regular cleaning?
- Yes, solar panels do require regular cleaning to maintain optimal performance. Accumulation of dust, dirt, leaves, bird droppings, and other debris can reduce the efficiency of the panels. Regular cleaning, either by homeowners or professional services, helps ensure maximum sunlight absorption and energy production.
- Q: Can solar panels be installed on metal roofs?
- Yes, solar panels can be installed on metal roofs. In fact, metal roofs are considered to be one of the best types of roofs for solar panel installation due to their durability, longevity, and ease of installation. The metal roof provides a stable and secure base for mounting the panels, ensuring optimal energy production. Additionally, the smooth surface of metal roofs allows for efficient panel placement, maximizing sunlight absorption.
- Q: Would it be possible to use a lens or a mirror to focus light onto a solar panel in order to make in more efficient? And is something like this already being used? It was just a thought and I haven't spent much time on it, but I figured I'd ask.
- yes it is being done. i've seen adds for such a system. on the other hand, if you had a 5 sq in Lens focused on a small cell, and a 5 sq in cell, they'd be about the same. in fact, the cell might be a bit better because (A) there wouldn't be any loss in the Lens, and (B) it might be that the solar cell would use some frequencies to which the Lens was opaque. in addition, the cost of solar cells is dropping, making the cost of the mirrors or lenses uneconomical by comparison.
- Q: My family moved into a house that came with solar power panels but they are not connected and don't really understand how to even begin.
- You will need help with this. Panels may or may not be 24 volt. If you can find a name tag, you can find out from the manufacturer's web site. Some folks hook them all in parallel. Mine are in series, to create 480 volts. the reason for going to higher voltage is to reduce power loss in the wiring. Even then, I used a wire size larger than recommended. The frames want to be interconnected, and wired to ground. The live conductors connect through disconnect switches to an inverter. The inverter is sized to the output of the panels. Where the utility allows net metering, the inverters are connected through a disconnect switch to the grid, which of course also feeds the house. Assuming you are on the grid, you will not need batteries. If outages severely impact you, you can have batteries. Counting against them is that they are costly, and use part of the power you generate, just to keep them charged. If you have batteries, it is usually best to rewire circuits so noncritical circuits are disconnected during outages. Leaving perhaps minimal lighting, fridge, freezer and critical medical circuits. Learn all you can from the Internet (try solar panels), and from the green search box above. Be sure to see if your state has a rebate program, and the conditions which it requires.
- Q: I don't want to spend a fortune, maybe talking like over $200 but I would like to power my computer, the monitor, my tv, and a small fridge.I looked up the price on some but it does not make any sense to me because it says that it has reached the price of less than $ per watt but if I look up a 20 watt solar panel it is $560 dollars. Why would it not be $20 because they said $ a watt.Where would be the best place to buy the cheapest solar panels?
- That's more like a bare laminate, and will not be durable, but will get you a legitimate $/watt. Also understand that if a manufacturer has a cost of $/watt, that means the panel will cost more by the time you buy it. It has to be shipped, stocked somewhere, and the retailer has to make a profit. $560 is high for a 20-watt panel today. Whoever is selling at that price will not sell many, or will sell only to those who aren't shopping around.
- Q: How much per sq inch do they cost? Will i have to worry about them blowing off during hurricane season? If the sun isnt out for a week will my power go out? Will I have to check them every week and check which ones arent working and replace them? Is there anyway for them to be damaged by acid rain or any type of erosion like hail? When do I have to replace them? How do I dispose of old ones (like recycling)? What is smarter and more economical having few big panels or many small ones? I know I have alot of questions but I want a good detailed answer.
- The cost of solar is measured in dollars per watt. That means the cost of a cell that can make one watt continuously in full sunlight. A friend of mine is starting a new job to set up a new solar cell factory and he said the present cost is $3 per watt, but that they expect to get that down to $ per watt in a few years. They can be damaged by weather, just like any regular roof. My insurance agent asked if I had solar panels, so it is a factor in insurance cost. I never heard of recycling or disposing of old panels, maybe because they are so new and last so long that not many are ready to be disposed of yet.
- Q: Hello,What do you all think about the future of solar panels and what role they will play in the near future. There is tons of money being dumped into the industry and demand is slowly rising. Also do you have any favorite solar links to get more info about them?
- I think the solar panel will be better as the development of technology. A solar panel company called OKorder once did a research of the future of solar panels and gave many datas to prove the bright future of it. Find it on Internet.
