FAQ:
（1）Have you ever sold your products to companies in my country?
Of course, we have customers in all general PV markets, but I think we should expand our market share along with the market growth.
（2）When did your company set up? You are a new company, how can I believe your quality?
We entered into Solar PV industry in 2005, now we have several plants in manufacturing of a-Si and c-Si panels, and our capacity is 220MW per year. Till now we have already passed all the tests by authorized laboratories, e.g. TUV, VDE, UL.
- Q: I'm re-doing my roof. Is it workable?Can I get a government grant or something to put solar panels on my roof?I know they did something like that for windows.
- solar panels take about 5 to 20 yrs to break even. for the average home
- Q: I'm just geting into electonics and stuff. So I am trying to make a simple USB charger. I'm looking for at least 4 volts output. What I've got is two solar panels (detached) a 4 AA battery holder, and a circuit board with an led on it (took the solar panels out of old lawn lights. I need more charge out of my panels (I think) so I tried attaching them. I soldered the positive wire from one to the positive connection on the other and negative wire to negative connection. After doing so and checking the multimeter, it says I have no output at all. How do you connect them?
- Huh? you should have got something, in full sun, you should have gotten 3 or 4 volts, but milliamps in current. By connecting them pos. to pos., neg to neg,(paralell) it increases the current output. If you connect pos, on one, to neg. on the other, and measure between the remaining pos, and neg. you should have twice the voltage (series). You need 4 volts, but 4 AA's in series is 6 volts. If your going to use the panels to charge the batteries, you'll need a diode in series to prevent discharge during dark conditions, which the LED will work for.
- Q: I mean like bread is made of wheat, what are solar panels made up of?How are they manufactured?
- Solar panels (aka photovoltaic panel) are most often made up of thin wafers of crystalline silicon or cadmium telluride. As photons from the sun enter the photovoltaic cell, electrons are freed from the substrate when are then collected by wires that run throughout the panel. And as we know electrons=electricity!
- Q: Hi! I bought a Coleman 2 vdc cooler that pulls 9 amps. What size solar panel and amp-hour battery do I need? I only open it 3 times a day. It will hold about 3 gals of milk.
- If it pulls 9 amps continuously, that's 08 watts/hour or about 2.5 kwh/day. If it only pulls half that (does it cycle?) it's about .2 kwh/day. You only want to drain a lead-acid battery 50% or so, so you'll want a 5 or 2.5 kwh battery pack. A typical setup for the 5 kwh would be two L-6 batteries in series, and for the 2.5 kwh you could use 2 T-05 batteries in series. This does not account for days of cloud. If you regularly have cloudy days, size the battery pack for two or three days of use with no input (2-3 x the sizes given above). To charge them, you typically want panels that will charge your battery at least 5% of its capacity per hour (C/20). For 2 volt nominal panels that's 0 amps for the T-05 or 20 amps for the L-6 batteries. It's good to have more than that for battery life (it cuts down on what's called stratification), so you'll want probably 50-200 watts of panels for the T-05 and 300-400 for the L-6. You'll also need a charge controller. Peltier coolers are very inefficient. You'll save money by using a regular mini-fridge and an inverter. Most mini-fridges only draw 50 watts or so, so you're talking 600 watt-hours for a 50% duty cycle. This means two T-05 batteries will give you two days of use and you'll only need 20-50 watts of panel. DK
- Q: I had someone quote me for solar panels on my house but I can't afford it. They were talking about how I have enough room and the perfect location to put many of them and actually get paid for it. I have about a half acre that is tiered and points in the correct direction for them to get pretty much the full day sun. Additionally, I live in so cal where it is sunny most of the year. Does anyone know if solar companies will lease or install them to get the payback? I would be happy to allow them to use the land just to cover my electrical expense and they could have any payback.
- Hi, In the UK solar companies will fit them for nothing. The company gets the government allowance (called feed in tarrif FIT) and you get the benefit of the reduction in your power bills. The solar company make better money than the householder,BUT if the householder is in most of the day it could be most beneficial if the energy is used while the panels are generating, this means the householder is not paying for the power from the grid. If the householder works normally from 9 to 5 then there is less advantage in terms of getting free power from the panels. Best Wishes.
- Q: Hi I need to replace the solar panel on my calculator and was wondering where I could buy one. Thanks in advance for your answers.
- My suggestion is to first make sure that your calculator does not also use a tiny button cell. It could just be that the battery went dead. Also know that it's probably less trouble to just get a whole new calculator. If you have the skills to replace the solar cell, I'd suggest first disconnecting it, and wiring a .5 volt battery in its place. If that doesn't work either, maybe the problem is not the solar cell at all, but just its connection, or even a dirty ON button. As for where to get a replacement solar cell, if it were me, I'd go to a dollar store, and see if they have a cheap solar calculator that I could harvest one from.
- Q: Is there a material that is capable of absorbing enough UV radiation to make it worth using as a flexible solar cell?Not flexible as in aluminum, but a material such as plastic (polycarbonate).
- Yes, they already exist. I have one here.
- Q: Can solar panels be installed on historical landmarks?
- Yes, solar panels can be installed on historical landmarks. However, the installation process needs to be carefully planned and executed to ensure that the historical integrity and aesthetics of the landmark are preserved.
- Q: What, if any, improvement in efficiency per square foot or meter is realized by a solar panel in space vs. being mounted on the ground where the light is attenuated by the atmosphere?In passing, I found a site that gives an output of .89 watts / 4 in. sq for a particular home-mounted panel.
- Solar panels on spacecraft are a lot more efficient than ones made for home use. That doesn't include the effect of the atmosphere.
- Q: Can solar panels be used to power a restaurant?
- Yes, solar panels can be used to power a restaurant. Solar panels harness energy from the sun and convert it into electricity, which can be used to power various appliances and systems in a restaurant, including lighting, refrigeration, cooking equipment, and HVAC systems. By installing solar panels, restaurants can reduce their dependency on traditional energy sources, lower their electricity bills, and contribute to a cleaner and more sustainable environment.
