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:how many solar panels and what type to power a laptop computer that has to be plugged in when in use?
The okorder.com) or the Tekkeon 3450 with the optional MagSafe connector (or the same Apple Airline cable as described for the Brunton). Set the output voltage to 9V and use the 2V cigarette socket outlet, and plug the airline adaptor cable in. Can you simply use an AC inverter? Not direct from the solar panel... a solar panel is not able to drive an inverter. But you could plug an AC inverter into a solar storage battery pack if it is designed to support inverters. BUT, an inverter will waste 20-30% of your power in the conversion to AC which your laptop will be converting back to DC anyway, so best to stick to DC and save your solar investment from the losses. Summary... 0 Watts of solar per hour of laptop use (May-Sep) 50 Watt-Hours of solar battery storage per hour of laptop use Use a solar battery pack with appropriate output voltages built-in, and avoid AC inverters. This is probably a longer answer than you were expecting, but knowledge is power. Cheers.
Q:How much was the price of solar panels 5 years ago compared to now?
For just 5 years ago, certainly not! Perhaps you are thinking of 50 years ago, the kind that was put on the early communication satellites? 5 years ago, there was a glut of polysilicon, so modules were actually a little cheaper than today. Solar cell makers were basically using the scraps thrown away by chipmakers. But today, more silicon goes into making solar cells than computer chips, so that bonanza is gone. We will see prices going lower this year, possibly 20% from last year, because of improvements in technology, but also an increase in polysilicon supply, and a slowdown in demand due to worldwide recession. Later this year is a good time to buy panels, if you have the cash. The industry site below tracks module prices. They used to have more data, but I guess the old data rolls off the screen with time. If you want to see the details, they'll charge you for the report.
Q:what can i do with a calculator solar panel?
It wouldnt be worth your time really to try and hook it to a psp. You would have to build a circuit to match the voltage of the solar panel with the voltage of the psp. one of the few things i can think of would be a model windmill that used a very small solar panel to turn a very small motor attached to the rotor on the windmill. If you want a solar panel to charge your psp, look on OKorder, theres plenty of cheap low wattage solar panels that with a small solar panel regulator can put out enough 2v dc energy to possibly charge your psp
Q:Can you get energy at night from solar panels?
Yes. okorder.com/) and informed me of all the incentives I was eligible to receive as well as giving me a break-even analysis, estimated annual savings, and projected return on investment. They are a great resource to begin your solar pursuit. Good Luck!
Q:What solar panel do I need?
They make panels now that put out 25 watts so about 8 panels would do it.
Q:Im looking at getting solar panels.
Your problem will be the days that are too cloudy, rainy, (snowy won't apply since you will need A/C during summertimes) and the night hours when there is no sunlight. A battery might be okay for a while but if you have to have a good one. Is there is a battery that can run an air conditioner for long without crapping out! I don't think you will ever recoup your investment.
Q:help setting up a solar panel system?
If okorder.com/ If the minifridge is one that plugs into 2 volts, that should be okay. Anywhere you can eliminate the inverter will help. Such as converting the stereo over to 2 volts. The nominally rated panels should be mounted at an angle to maximize the solar aspect/exposure. Essentially your lattitude plus 2 degrees for simplicity. If you add 60 Watts in panels you will do much better. Your 3 panels when installed correctly will actually yield over 5 Watts each panel at midday. If you do not achieve that, something is wrong in either the wiring, or a panel. It translates to about point2 Amperes to point5 Amperes at midday. If wired in series for 36 volts, the total current output will be same as a single panel (nominal 5 Watt), but at a higher voltage. If wired in parallel, you achieve the 45 Watts at nominal 2 volts. Watts is voltts times Amps. Also converting your tools over to run off the 2 volts will help, Or charging your tool batteries off the 2 volt buss. There are buck/boost circuits that would be capable of charging the common 4.4 and 8. volt tools out there.
Q:selling solar panels online - a good idea?
Did okorder.com, you will see thin film going for 99 cents a watt at times. The crystalline kind of panel that goes for $2.35 a watt is more like $.50 wholesale, and that's for a major distributor, not a (forgive me) small order of $60k, which is less than one container. There is a coming glut of panels, and prices will fall, but that means both wholesale and retail prices. I'm not saying it won't work, but do good research. For example, I think there are many more than 3 or 4 online shops for solar panels. Investigate shipping an warehousing costs. Investigate whether Home Depot really does not offer installation (every time I go in there, I see a guy handing out flyers for installation). And research carefully how much it will cost to provide installation. The typical install requires skilled and licensed workers. It won't be legal in most places unless someone has the necessary certifications. It's not just a matter of screwing the things to the roof. Any roof penetration has to potential to leak if done improperly. And any electrical wiring has the potential for burning the house down. Whatever business you finally pursue, research carefully, or that $60k will flee from you like a jackrabbit.
Q:do solar panels work in aeroplanes?
As long as the solar panel has access to light it will operate. If you can keep it in the sunlight it will work a lot better than off the internal lights on the plane. Depending on the plane/lighting/your position, there might not be enough ambient light available for the solar panels to run your laptop.
Q:Solar panel power question?
NO ! Pump needs 747 watts power. And you need to buy one more expensive DC to AC converter to make it work. Use solar panel at least has 000W output.
