We have organized several common questions for our clients，may help you sincerely：
1. What’s price per watt?
A: It’s depends on the quantity, delivery date and payment terms of the order. We can talk further about the detail price issue. Our products is high quality with lower price level.
2. Can you tell me the parameter of your solar cells?
We have different series of cells with different power output, both from c-si to a-si. Please take our specification sheet for your reference.
3. 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.
- Q:Have a 40watt 20volt solar panel, how many watt of inverter do I need?
- 500 Watt Solar Panel
- Q:Solar Panels: How long will it be before solar panels are cheap & effecient enough so that everyone?
- I know 4 families that not only power their entire homes with their panels (including their AC during the summer), they contribute electricity to the grid and have a negative electric bill. They also got a big rebate from our local electric company, SoCal Edison, for installing the panels. Maybe the worthiness of solar panels depends on how many days of sun the roof of your home gets during the year.
- Q:how can i build a solar panel?
- You might need some help from the sun.
- Q:solar panels on projectors?
- Unlikely to prove useful. Solar panels don't generate very much current. You would probably wind up spending several thousand dollars, and wind up with a solar panel array (including batteries and power inverter) that is certainly not portable. You will also need adequate current for your projection source (ie DVD player or computer), as well as sound. By and large, the cheapest projectors require the least amount of power. There is no way around the fact that, for a projector to be practical, it must output out a great deal of light. Adequate light requires adequate current.
- Q:What would be a good battery for this solar panel?
- How many batteries you will need depends on what you are planning to do with them which you did not mention? Sunforce makes a 30 amp charge controller part no. 60033
- Q:how efficient are flexible solar panels?
- Up to now, it has very poor efficiency, about 5% to 23%.
- Q:How to hook up a Solar Panel To a single outlet?
- That solar panel puts out about amp (in round numbers). If you are talking about a 20vac outlet, you'll have to send the output of the solar panel through an inverter. That brings it up to 20vac. 20 watts at 20 volts means you'll only be able to draw 0.6667 amps. With an inverter at 85% efficiency, you'll only get about 0.4 amps. That would barely light a CFL. 20 watts of power at 7 volts = amp (in round numbers) 20 watts of power at 20vac = 0.6667 amp (in round numbers) Power (watts) = current x voltage. If you increase voltate, you must decrease current to get the same watts. Watts is the common denominator in power measurement.
- Q:projector/solar panels help?
- Do understand, that a solar panel is slow to pay for itself. Let's say your electric bill was $200 a month ($2400 a year). A solar system would cost perhaps $24,000 so you would actually have paid your first 0 years of electricity in advance when installing the panels. After that 0 years, you start to be ahead financially. It can still be a good idea, but it may not be the quick and cheap solution you were looking for.
- Q:How can I regulate current from a solar panel?
- Lithium batteries do have special charging requirements. I would recommend that you use the 2 volt charger that came with them to keep them happy. Automotive power systems can have voltages as high as 4.5 volts when the engine is running so there's no need to limit the output of the panel to anything less than that. Check with the charger manufacturer to see what it will withstand. Some will work with systems up to 24 volts nominal (up to 29 volts actual) found in larger commercial vehicles such as trucks and busses. If your charger will work with both 2 and 24 volt systems you might not need anything extra to use the unregulated output of the panel. Otherwise I'd recommend a shunt regulator to clamp the output of the panel to no more than 4.5 volts. That way it would dissipate (waste) very little of the panel's power, and even that would only be during those rare times when the panel is producing maximum output. Such a device could be as simple as a high power zener diode, a low power zener coupled with a power transistor, or a precision shunt regulator such as a TL43 coupled with a power transistor. A more complex way would be a to use buck/boost regulator between the panel and your charger. You might gain a slight advantage under low light conditions when the panel isn't putting out much but the overall efficiency could end up worse than the simpler shunt regulator. Under optimum conditions, I would expect it to take a full day for a 3 watt (peak) panel to charge just one of your 35 Wh batteries. Charging an intermediate device such as the Sherpa 50 through its built in charger and then using it to charge your battery through yet another charger would severely cut your overall efficiency. Depending on how long you'll be gone, it might be far more practical, reliable, and economical to just carry (or find a way to be resupplied with) a few additional fully charged 35 Wh batteries. Don
- Q:Help choosing solar panels?
- first okorder.com/ example: house roof is 20' x 20' 20' = 240, so sq. inches of roof is = 57,600 say rain fall for your area is 3 per month on average. 57,600 x 3 = 72,800 of rain collected. Using the conversion chart link above, that many cubic inches of water = 750 gallons of water free per month. Look at your water bill and see how much you use. Solar panels take on average 2-20 yrs to pay themselves off, just in time for them to be replaced. Paddle wheels go on for just about forever. We still find large paddle wheel mills in the USA that are over 200 yrs old, and still functioning.
