CNBM Poly Solar Panel 255W A Grade with Factory Price
Production description
A solar panel is a collection of solar cells. Lots of small solar cells spread over a large area can work together to provide enough power to be useful. The more light that hits a cell, the more electricity it produces, so spacecraft are usually designed with solar panels that can always be pointed at the Sun even as the rest of the body of the spacecraft moves around, much as a tank turret can be aimed independently of where the tank is going.
There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, a solar inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

- Q: The first panel is located in New England, the second is placed in the Sahara desert, the third is on the Earth side of the moon, and the last is on the far side of the moon. Which panel would absorb the most sunlight over a year's time and why ? All the panels are place in optimal places where they would get the most light available.
- probly the sahara desert since it there's not much rain there which would equal few clouds. you'd get plenty of direct sunlight. the moon is constantly orbiting earth and in different possisions with the sun which would equal less sun exposure.
- Q: Is there any way to charge my laptop with a solar panel? Is there any panel like that. Or if I work on panels can I do something like that. If you know anything about it, can you just help me? Thanks a lot.
- A solar panel is usually 36 cells and intended to charge a 2V lead acid battery. The battery in laptops may be somewhere between 5 and 20V. The panel might charge a laptop when it is cold, but they heat up in the sun and then it would no longer charge. Typical lap top power supplies are 3 to 4 amps. You need 2 panels in series to get enough voltage to charge the battery directly, but this is wasteful. If you want to charge at the same rate as a lap top power supply you need large panels to provide 5 amps. The 5 Amp panel will only give 5A when pointed directly at the full sun. There may be between 2 and 5 hours a day equivalent full sun depending where you are, time of year. If you want more than that, you need larger panels, or more than one in parallel for a 2V system. It makes sense to charge a 2V battery with the solar panel, and use that to operate the lap top with a car type power supply for a laptop, which runs from a 2V battery (see link below for an example). Get the biggest panel you can afford, and the battery should be larger if you want to run the lap top when the sun isn't shining. Perhaps a 20AH battery is a minimum size. All this costs more than a lap top.
- Q: Single crystal solar panels and polycrystalline solar panels
- monocrystalline silicon market share and a slight increase, and now the market to see the majority of single-crystal silicon cells. Monocrystalline silicon solar cell silicon crystal is very perfect, its optical, electrical and mechanical properties are very uniform, the color of the battery is mostly black or dark, especially for small pieces of small pieces of consumer products.
- Q: K i'm almost ready to give up! I've bought every kind of pv I can think of, and I can see this technology will not be affordable in my lifetime.I conserve all I can (so far as to handwashing my laundry etc) I'm not rich, but I'm saving for a solar pv with decent amperage. I love tinkering with things if I see the point.All the cells i've seen are very weak. What PV would you buy? (all I need is to power my computer from a deep cycle 2 volt battery connected to an inverter)God Bless You
- For okorder . If powering a PC is your only goal, consider replacing the power supply in your PC with one that runs off native 2 volts (like the kind intended for RV's). Then you can avoid the 30% loss of energy in a cheap inverter. I think you will see a significant drop in the price of panels in the next couple years, by the way.
- Q: How to make a simple solar panel?
- There are many kinds of solar panels. Please specify single crystal, poly crystaline, gallium arsenide, thin film, or water heating solar panel. How much detail do you need? Are you actually making one or just writing a report? If you expect a meaningful answer you need to provide background information.
- Q: hi,i have 4 solar panels. I can get 9V 400mA when i wired them parallel. The question is: how can i make a regulator circuit to store power into batteries.
- wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .
- Q: all i want to do is provide enough electricity for 2 fluorescent bulbs i was looking at some 80 watt panels how many of those would i need and what else do i need for storing the electricity for use at nite? and how much would it all cost?
- The solar panels are made in China because there are fewer environmental regulations and cheap coal power. It takes a lot of energy to melt silicon and there are toxic waste products. It would be three to five times more expensive to make the panels in the US ( three times is just for reprocessing the toxic wastes ). Solar cell made in China are about $2 a watt, perhaps as low as $ a watt but in truth the claims for $ a watt or less solar panels as in thin film solar panels have much lower efficiency and require perhaps ten times more surface area.
- Q: Can solar panels be used in apartments or condominiums?
- Yes, solar panels can be used in apartments or condominiums. However, the feasibility of installation and usage may vary depending on the specific circumstances of the building, such as roof space, orientation, and ownership structure. Some apartments and condominiums have successfully implemented shared solar systems or community solar programs to enable residents to benefit from solar energy.
- Q: I want to build a standalone wifi repeater -- powered by the sun. The problem is how much solar power and how big of a battery?net draw 4.5v @ 0.66A with loadnet draw 4.5v @ 0.60A no loadI'm assuming the best choice would be a 6v battery with a a couple diodes in series to induce ~.5v drop. Then, I need something to charge it -- I found 2v 6w solar chargers in the automotive section of Sears and 6v 2w solar chargers in the marine section of Dick's Sporting Goods.How many solar panels and what capacity batteries should I use? Is this the best method or should I use a voltage regulator and go with 2v batteries?I need this to be as cheap and simple as possible...
- I do not know, but there is a house in Lafayette which was built with solar power. It was to have a solar system, so the contractor's first act was to put up a solar array on the property. It had battery backup, and was used to provide the electrical power during construction. during completion of the house the solar system was installed on the roof of the house.
- Q: Can you connect a solar panel to speakers that use a wall outlet plug, by cutting the plug off and connect copper wire between the solar panel and cord?Confusing i know. I'm trying to connect a solar panel to speakers for a science project.
- Solar panels produce direct current, the wall plug is alternating. You cannot without an inverter. However, electrical devices smooth out this alternating current using those big power adapters and such. If you find how much voltage your speaker requires you should be able to power the amplifier directly with the solar panel, and have the input from the normal source..
