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: How much energy can be generated from a solar panel on a clear, bright summer's day for example?
- it depends on the size of the panel and if it is installed in an optimal location. there are many 00W panels commercially available and they can be ganged for a number of different output configurations.
- Q: Can solar panels be installed on ski resorts?
- Yes, solar panels can be installed on ski resorts. In fact, many ski resorts have already implemented solar energy systems to reduce their reliance on traditional energy sources and lower their carbon footprint. Solar panels can be installed on rooftops, parking structures, or open spaces within the resort premises, providing clean and renewable energy to power various operations, such as lifts, lighting, and heating systems.
- Q: If a solar panel is a .5kW system, what length of time is it putting out that much power? Every hour?
- Power = work done/time taken In other words, Watts=Joules/second. In this respect, power is a little like speed (m/s). Your question is looking at a car with a 50mph top speed, and asking how long is it going that fast? The solar panel will produce .5KW for as long as you require it. Enough to boil a kettle, run a modest electric heater etc,
- Q: Ok so i have to solar panels to charge a battery however the panels hooked up in series does charge the battery very slowly because series connections only multiplies the voltage but leaves the current the same. Is there a way i can also hook both of them up in parallel at the same time to multiply the current for faster charge? I know i can do this with 4 panels but i dont want to spend extra. So is there a way to hook up 2 solar panels in series and parallel at the same time? Thanks in advace
- No. Series means one thing, parallel another, and they are mutually exclusive.
- Q: i want to build a stationary model of a solar panel and i dont know if it is going to be too simple or not i also want ideas to make it betterplease criticism is allowedmy idea was to make a case, just like a real solar panel, and take plexiglass to make it. i want to add some models of photovoltaic cells that look like they are in a solar panel . i want to add the fake shoulderings as well . i want to make the case openable by hinges.i would like some of your thoughts and ideas to help me .thx

- Q: I have an inverter and a battery 20 Amperes.Daily sun shine approx. 7 Hours.Do I need to buy anything or should I connect the solar panel to the Battery direct?
- No, don't connect the panel directly to the battery. You need to isolate the solar panel charging output from the AC-powered charger. A couple of high-current diodes arranged with their anodes connected to the charging sources in the positive supply line will allow either the charger or the solar panel to lift the voltage high enough to charge the battery, albeit with about 0.6 volts dropped across the diode. Both cathode ends would be connected to the battery. This arrangement allows a positive current to flow from either or both charging sources at the same time, although in practice, one will generally be higher than the other. Also, if the AC charger's voltage is significantly higher than the solar panel, the charger may always charge the battery. You would need to regulate its output to be slightly lower than the solar panel when it's near it's minimum useful operating voltage. (note that the 0.6 forward bias voltage on the diode might prevent the solar panel from completely charging the battery if it has any voltage regulation on its output)
- Q: Can solar panels be used in areas with high humidity or saltwater exposure?
- Yes, solar panels can be used in areas with high humidity or saltwater exposure. However, it is important to use solar panels specifically designed to withstand these environmental conditions. These panels are typically made with corrosion-resistant materials and protective coatings to ensure their longevity and performance in such areas. Regular maintenance and cleaning may also be required to prevent any build-up or damage caused by saltwater or high humidity.
- Q: How long does it take a 5 watt, 2 volt solar panel to charge a 2 volt R.V. battery?
- Most solar panels have something called a charge controller on them. This prevents electricity from going backwards from the battery to the panel. Solar panels are rated at 2V but they do put out a little more than that during full sun operation. You didn't specify the size of your battery but it really doesn't matter. It comes down to your consumption of power. If you are only charging the RV battery so it maintains a charge when you don't use it very much, a 5 watt panel is fine. It will charge the battery and keep the small drains on the battery from making it go dead ( the clock radio, the theft deterrent system, etc use power even when RV is off) But if you are using the battery to run things when you are parked, you probably don't have a big enough panel. If you use a 30watt fluorescent light and a 00 watt laptop, you need 30 watts of power saved up every hour in your battery and that's with no inefficiencies. So if your panel puts out 5 watts an hour and you are using 30 watts an hour, you need 30 watts/ 5 watts = 9 hours minimum of charge time to run your stuff for just one hour. You probably need a panel of around a 00 watts to get any meaningful use of your battery. Plus, you never want to run your battery to full drain because it ruins the plates inside the battery. Watts = volts x amps. If you have 2 volts panels, you would charge at 8 amps with a 00 watt panel. This is a good charge rate. Any more than this and you risk warping the plates with too much heat.
- Q: Can solar panels be installed on agricultural or farming operations?
- Yes, solar panels can be installed on agricultural or farming operations. In fact, they are increasingly being adopted in these settings to generate clean and renewable energy. Solar panels can be installed on rooftops of barns, sheds, or other structures, as well as on open fields or unused land. By harnessing solar energy, farmers can reduce their electricity costs, lower their carbon footprint, and contribute to a more sustainable farming practice. Additionally, solar panels can provide shading for livestock or crops, minimizing heat stress and improving overall farm productivity.
- Q: Can solar panels be used to power a hospital?
- Yes, solar panels can be used to power a hospital. Solar panels convert sunlight into electricity, which can be used to meet the energy needs of various facilities, including hospitals. By installing a solar power system, a hospital can generate clean and renewable energy, reducing its reliance on traditional grid power and potentially saving costs in the long run. However, the feasibility of using solar panels to power a hospital depends on factors such as the hospital's energy requirements, available space for solar panel installation, and the local climate conditions. Additionally, backup power solutions may be necessary to ensure uninterrupted electricity supply during periods of low sunlight or system maintenance.
