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.
WIRING
To ensure proper system operation to maintain your warranty, observe the correct cable connection polarity(Figures 1&2) when connecting the modules to a battery or to other modules. If not connected correctly, the bypass diode could be destroyed.
PV modules can be wired in series to increase voltage. Connect wires from the positive terminal of one module to the negative of the next module. Figure shows modules connected in series .

- Q: I have two solar panels that were going to be trashed at work. I want to use them to charge batteries on my RV but i noticed they put out around 20 volts in direct sunlight. So i am wondering: -isn't this way too much voltage for a 2 volt system? -do a need some sort of a regulator connected to keep them from overcharging?
- You can use them without the regulator . Just make sure you use blocking diodes so the the power does not flow back into the panels . You can get those at radio shack of some electronic store or off OKorder for a few bucks .
- Q: i need how a solar panel works, if possible make as easy to understand as possible like because of this , this happens and if you could please put a web source you got it from
- How okorder /... Use the next page link to flip through the article.
- Q: Can solar panels power a whole house?
- Yes, solar panels can power a whole house. With the right number of solar panels installed and optimal sunlight exposure, they can generate enough electricity to meet the energy needs of a typical household. However, it is important to consider factors such as the size of the house, energy consumption, and storage options to ensure a reliable and consistent power supply.
- Q: It measured volts before I attached it, and after attaching the voltage regulator device, the voltage dropped down to 3 volts, even when just measuring the difference in the solar panels nodes themselves, suggesting that the entire panels voltage dropped and not just the voltage in the regulator. I tried testing it with a power supply of 7 V 0. A and it works fine, but I don't know why it won't work for the solar panel.
- you cannot treat the open circuit voltage of a solar panel like a voltage source (like a battery.) the load response of the panel doesn't behave that way. small panels and panels that are producing less than about .5A are very happy to have their output voltage pulled down to whatever they're connected to (typically zero.) I observed the same phenomenon when i connected a 2V 725mA panel to a 2V 325mA fan -- the open circuit voltage of 5V dropped to 3V when connected to the fan, and returned to 5V when disconnected. The easiest workaround is to use 2V of rechargable batteries in parallel with the panel so that the battery holds the 2V potential difference and the panel just supplies the current. any excess current charges the batteries, so you might consider whether or not you need some type of charge controller to prevent burning the batteries via overcharging. there are actually very few applications of solar panels connected directly to circuits that i have seen that have any kind of robust performance -- if they work at all, they eventually die/burn themselves out in a couple of months. the best robust designs always have a rechargable battery and charge controller somewhere in the power circuitry to buffer the load circuit from the panel. .
- Q: What is the impact of bird droppings on solar panels?
- Bird droppings can have a negative impact on solar panels as they can reduce the efficiency of the panels by blocking sunlight. The droppings can create shadows and reduce the amount of sunlight that reaches the panels, leading to decreased energy production. Additionally, the acidic nature of bird droppings can damage the surface of the panels if not cleaned regularly, potentially reducing their lifespan. Therefore, it is important to regularly clean and maintain solar panels to ensure optimal performance and longevity.
- Q: Can solar panels be used to power a school?
- Yes, solar panels can definitely be used to power a school. Solar panels convert sunlight into electricity, which can be used to power various electrical systems within a school, including lighting, heating/cooling systems, computers, and other appliances. By harnessing solar energy, schools can reduce their dependence on traditional sources of electricity and contribute to a more sustainable and eco-friendly environment.
- Q: How do solar panels affect the property's overall sustainability?
- Solar panels can significantly improve a property's overall sustainability by harnessing clean, renewable energy from the sun. By generating electricity without emitting harmful greenhouse gases, solar panels reduce the property's carbon footprint and help combat climate change. Additionally, solar panels can lower energy bills, increase energy independence, and potentially provide a source of income through net metering or selling excess electricity back to the grid.
- Q: Can solar panels be used in conjunction with energy-efficient appliances?
- Yes, solar panels can definitely be used in conjunction with energy-efficient appliances. In fact, combining solar panels with energy-efficient appliances is a great way to maximize energy savings and reduce environmental impact. By generating clean and renewable electricity, solar panels can power energy-efficient appliances, ensuring a more sustainable and cost-effective energy solution for homes and businesses.
- Q: when building a solar panel should the diode be on the positive or negative sidelittle more detail i just built a solar panel and im running it to a grid tie converter should i put diodes in if i add another panel or are they only for battery systems?
- Bypass diodes would be in parallel with groups of solar cells in a panel. For example, if a module has 72 cells, maybe every 8 cells, there will be a bypass diode. A bypass diode does nothing except salvage some of the energy from the panel if some of the cells are shaded, and others are not. Or, if you have multiple panels in a series string, the bypass diodes allow the other panels in a string to continue to contribute energy when one panel is shaded. Unless you're forced to put the panel(s) where there will be shade during the day, the bypass diode does not matter. Commercial panels all include bypass diodes. Blocking diodes are generally NOT included on commercial panels. If you're going to a grid-tied inverter, you probably don't need one. There are stringent regulations on how panels must be grounded, and whichever side of the panel is grounded should not have a blocking diode. NEC regulations call for a continuous ground to earth. For example, if you have negative ground on your system, the blocking diodes, if any, should go on the positive terminal of the panel. By the way, if you're in the US or Canada, do understand that a home-built panel will not be legal to connect to a grid-tied system. And a grid-tied inverter that plugs into the wall will also be illegal. I'm only saying this because I don't want you to get hurt, or your house to burn down. Line power is nothing to be trifled with.
- Q: I'm looking into buying solar panels, there are all kinds of ranges of energy output...but my question is, when ti says...say 50 watts of power...does that mean 50 watts a day, an hour, a minute, what?
- A 50-watt rating means the panel will produce 50 watts as long as the standard conditions are maintained. So if you had this bright sun and cool temperatures for 6 hours, the panel would deliver 50 x 6 = 900 watt hours, or a little shy of kilowatt-hour. Kilowatt-hours (kWh) is the reading on your electric bill. However, like most advertising, the 50-watt number is not realistic. They assume that the air surrounding the panel is very cold. 25 watts is a better number to use for this size of panel for engineering purposes.
