FAQ1
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.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: Do higher watt solar panels last longer, efficiency-wise? 3 installers gave me quotes with 3 different sunpower panels. The 225, 25, 20 watt panels. Whats the con and pro's of the different wattages?
- You should get the highest efficiency at the lowest price. Typically, the Sunpower brand panels have the industry best 23% efficiency depending on the model. You have to look at the specification very closely and if you don't see it, ask. There are two types of solar cells Polycrystalline and Monocrystalline. Polycrystalline cells are inferior to Monocrystalline. You will also see that different kinds of panels have different output voltages.Since you will be wiring your panels together and connecting them to either a power inverter or a charge controller (if you have battery backup), you need to make sure the panels and controller work together for maximum efficiency. Be very careful when engaging an installer especially when they are trying to sell you the equipment too. Mostly, these are not engineers and you will end up with whatever they have in stock without regard for the most optimal design.
- Q: Why can't they put solar-panels on the blades and sides of the 300-500 foot tall turbines? Wouldn't this increase effeciency? Therefore, boosting pay-back time, profits, energy-output?
- Hmm, okorder /.. Glad to see you thinking though, keep it up! Knowledge is power the more knowledge you gain about a variety of subjects processes the more you truly understand the truth depth of that statement.
- Q: Can solar panels be used for powering a marina or boating facility?
- Yes, solar panels can be used to power a marina or boating facility. Solar energy can provide a reliable and sustainable source of power for various applications such as lighting, charging stations, refrigeration, and other electrical needs in a marina or boating facility. By harnessing the sun's energy, solar panels can significantly reduce dependency on traditional electricity sources, lower operating costs, and promote environmental sustainability.
- Q: i have 2 questions.. I have a 6v solar panel, if i wanted to charge batteries with that it what batteries could i charge? Could charge normal AA batteries with it our do i need special batteries.2. I have a 6v solar panel that produces watt. I want to light a bulb with it but whenever i hook it up the solar panel won't light it up. I think the current of the solar panel is too low. How can i increase the current of the solar panel
- [] Use it to charge 4 pieces AA cell ( connect in series to make 5V battery pack ) for 0 to 4 hours. Good for cell rated 600mAH ,2000mAH,2500mAH. [2] Cannot increase current. Buy some more this panel and hook them together in parallel to increase current. You need at least ten pieces to make current reaches .6A to light up some 6V bulbs.
- Q: I am thinking of buying a 3w solar panel called the nomad 3 from goal zero. I want to charge 35Wh lithum batteries. I have heard that lithium batteries are temperatmental and without a regulated current things could get ugly.I have a couple of chargers that came with the batteries. One is a 2v car charger and another is 0-240v wall charger.Goal zero sell something called a sherpa 50, which contains rechargeable batteries and an inverster and I think they suggest that I charge my batteries indirectly through the Sherpa 50, however, the sherpa 50 is expensive at $200, and seems to have a small capacity, in addition to being extra weight that i don`t want to carry.Electronics geniuses, you are my only hope.
- 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: thinking of getting a portable solar panel laptop charger...may be a stupid question but may be a very intelligent one as well ;)
- Depends on the efficiency of your solar panel, but it is highly unlikely that the light in an airplane is enough to do much. I'm not discouraging the solar panel altogether. It just isn't an indoors especially if it is dim on the plane. Most that I've been on turn off the lights and then leave it to the individual to turn on the single over head reading light.
- Q: Can solar panels be used to power a cruise ship?
- Yes, solar panels can be used to power a cruise ship to some extent. However, due to the large energy requirements of a cruise ship, solar power alone may not be sufficient to provide the necessary electricity for all onboard facilities and operations. It is more common to integrate solar panels with other power sources, such as traditional fuel-based generators, to supplement the energy needs of a cruise ship.
- Q: Can solar panels be used to power swimming pools?
- Yes, solar panels can indeed be used to power swimming pools. Solar panels can generate electricity from sunlight, which can be used to operate pool pumps, heaters, and other equipment, reducing the reliance on traditional electricity sources and saving on energy costs.
- Q: Can solar panels be installed on a tennis court or sports complex?
- Yes, solar panels can be installed on a tennis court or sports complex. These areas often have large open spaces with ample sunlight, making them ideal for solar panel installations. Additionally, integrating solar panels into sports facilities can help offset energy costs and promote sustainability.
- Q: name things someone could use solar panels for or make with solar panels? (use solar energy i mean?)
- Solar panels can produce enough energy to run your average size unit (depends on panel size). It cost you bit more but its for once in all, average panel age limit is above 20 years (approx) so it can save you a lot, also environment friendly. Basic Panel can support your lights which are mostly used in any premise, even your TV, computer and stereo system. Is that enough to save and entertain you?.....Think so.
