We have organized several common questions for our clients,may help you sincerely:

1.what price for each watt?

it depends on the quantity, delivery date and payment terms,

2.what is your size for each module? can you tell me the parameter of your module?

we have different series of panels in different output, both c-si and a-si. please take the specification sheet for your reference.

3.Can you provide the peripheral products of the solar panels, such as the battery, controller, and inverter? If so, can you tell me how do they match each other?

Yes, we can, we have two companies for solar region, one is CNBM International, the other is CNBM engineering Co.

We can provide you not only the solar module but also Solar Cells, the off grid solar system, we can also provide you service with on grid plant.

4What is your warranty system?

Our product performance guarantees for 25 years

• 12 years guarantee for workmanship

• Timeliness of delivery

• Quality Products certified (TÜV, UL, CE, ISO)

5.How do you pack your products?

We have rich experience on how to pack the panels to make sure the safety on shipment when it arrives at the destination.

6. Can you do OEM for us?

Yes, we can.

Q:What Size Solar Panel Would I Need?
Solar in Chicago is not much help, you would need at least 3kwh for whatever size unit you have, (3 tons is meaningless in this context!) You would not get enough sun even in the summer to operate for more thn 6 hours a day. For Chicago you probably need a wind generator, or go for a heat pump.
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:How many Watts of solar panels?
Running an oven or stove on solar is not a practicality; too much power is needed, use gas. Ditto, heating using solar electricity is not a practicality, and AC would also be asking a lot. The other things, within limits, might be do-able. You'll be needing as many solar panels as you can fit on. If I was you I'd consult a solar installer about how big your battery bank should be once you have decided how many Watts of panels you can put on.
Q:Solar panel for laptop?
laptop don't get enough power.
Q:I need some ideas for a going green program involving solar paneling.?
nasa solar panels seem to be better than silica / silicone (i forgot the exact chemical) they make them with ink and aluminum then case them in glass, they are supposed to last like 30 years or something. good stuff. anyway a SLOGAN: solar pannels save money, and over the long run allow the school to save tht momney or use it somewhere else in the school, ie better food, better seats, better computers, whtever. maybe you can relate the campain slogan to what the savings will be used for. maybe a new scince program thats funded solely on the savings of the panels. but ok a slogan: IT'S OBSCEEEENCE, ROTFL... GIVE SOME DOLLAR$$ AND GO GREEEEEN!!!!!! eh, i know not so hot, gimme a minuet. lol LET'S MAKE THIS PANEL HAP'N CAP'N... MIB! LMAO THE SUN, FREE FUN, COME ON AT LEAST GIVE ONE (place pic of dollar bill below the ONE) good luck.
Q:Where can I get damaged solar panels?
Test the battery. Connect the positive and negative terminals of the battery to the positive and negative probes of the voltmeter. If a voltage is read, the battery is still good. Remember, however, that this is a rechargeable battery, so if it is dead, it can be recharged.

Q:Why did the voltage of a solar panel drop significantly after putting it through a step down voltage regulator?
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:Solar panel?
Angle is everything. The more angled away from perpendicular, the more light energy simply bounces away. Think of it like a windmill that can only spin, it can't change direction with the wind. If the wind is pointed through the vanes, the vanes turn and power is generated. If the wind is coming from the side, nothing moves and no power is generated.
