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: The Physics club in our school is trying to convince the Board of Ed to install solar panels in our school, and i was just wondering if anyone with some experience or real expertise in solar energy. I need some points about their usefulness some real pros and cons on maintenance, etc. Anything will help. Personally i would be perfectly for the idea, but i heard that the overall cost of installing them is much higher than the cost of the energy saved and government subsidies, but ive only heard about this.
- Solar panels give off no pollution, the only pollution produced as a result of solar panels is the manufacturing of these devices in factories, transportation of the goods, and installation. The production of energy from the use of fossil and some renewable fuels (e.g. wind turbines) can be noisy, yet solar energy produces electricity very quietly. One of the great pros of solar energy is the ability to harness electricity in remote locations that are not linked to a national grid. A prime example of this is in space, where satellites are powered by high efficiency solar cells. The installation of solar panels in remote locations is usually much more cost effective than laying the required high voltage wires. Solar energy can be very efficient in a large area of the globe, and new technologies allow for a more efficient energy production on overcast/dull days. Solar panels can be installed on top of many rooftops, which eliminates the problem of finding the required space for solar panel placement. Another great pro of solar energy is the cost. Although the initial investment of solar cells may be high, once installed, they provide a free source of electricity, which will pay off over the coming years. The use of solar energy to produce electricity allows the user to become less dependent on the worlds fossil fuel supplies.
- Q: Can solar panels be installed on a residential community or housing complex?
- Yes, solar panels can be installed on a residential community or housing complex. In fact, many residential communities and housing complexes are increasingly adopting solar energy as a sustainable and cost-effective power source. Installing solar panels can help generate clean and renewable electricity, reduce energy bills, and contribute to a greener environment.
- Q: hi,i have 4 solar panels. I can get 9V 400mA when i wired them parallel. The question is: how can i make a regulator circuit to store power into batteries.
- wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .
- Q: Can solar panels be installed on a government building?
- Yes, solar panels can be installed on government buildings. Many government buildings have started adopting solar energy to reduce their reliance on traditional energy sources and to promote sustainability. The installation of solar panels on government buildings not only helps to decrease energy costs but also contributes to the overall effort of transitioning to cleaner and renewable energy sources.
- Q: I contend:As far as the solar panels causing global warming I'll try to explain. If you put a black panel on the ground or on your house and don't connect it to anything, it will absorb solar energy (heat) during daylight and release it at night (radiation). The net heat gain is zero. If you hook up a solar panel in the same place but hook it up to batteries, charge the batteries during sunlight hours and using that energy to electrically heat the home at night. The panels will absorb solar energy during the day but will convert that to electrical energy in the batteries instead of radiating it back into space at night. The result is a net gain in earth's temperature.Right or wrong?
- If you put a black panel on the ground or on your house and don't connect it to anything, it will absorb solar energy (heat) during daylight and release it at night (radiation). Not exactly. Assuming the black panel establishes an equilibrium temperature, it's going to be losing exactly as much heat as it's receiving during the day. Some will radiate out into space, some will conduct or convect into the atmosphere. As a wild guess, maybe 50/50. If you hook up a solar panel in the same place but hook it up to batteries, charge the batteries during sunlight hours and using that energy to electrically heat the home at night. The panels will absorb solar energy during the day but will convert that to electrical energy in the batteries instead of radiating it back into space at night. The panels are only about 4% efficient, so it's the same situation as the pure black panel for 86% of the energy. The remaining 4% will get stored in the batteries and then converted to heat at night. That heat will eventually leak out of the house and warm up the Earth a tiny bit. I think it's much the same situation either way. With the black panel the energy gets radiated / conducted/convected right away. With the solar panel a small percentage is stored and not so much is radiated, mostly conducted and convected. You're partly right as a black panel is going to radiate more into space than a house. But you're taking about maybe some day about 4% of % of the differening radiation/convection/conduction fraction, of the Earth's surface area. Probably not significant.
- Q: What is the average annual energy output of solar panels that can be installed on the home?
- The output of a solar panel would depend on your location and panel size. Most solar panels are rated using 000 Watts per square metre from the sun. This is only possible at the equator. Some supplier have online estimators for output depending on your location. Solar panels rate up to about 250 Watts per panel. I have an online calculator to work out the costs and benefits of solar. You can compare the costs of solar setup and 25 years of electricity versus buying from the grid.
- Q: I was trying to look online for solar panels for my home to take some of the strain off of using oil and electricity but I find it very hard to understand exactly how they are used.Like one that I looked up is 00 watts.....is that like a light bulb watt? How many things can that power? Is it really cheaper in the long run because the panels are very expensive?If anyone has web sites that can explain this to me I would appreciate a link, or anyone to answer part of my question.

- Q: Due to erratic power cuts in my area I want to make up by using a 30watt solar panel. My decoder is 30watt but my TV is 70W. I need something small. I don't have problem with sound. Just picture.
- Do what we do when power is cut (although we have very reliable power - we loose as much as 2 hours a year), is go Amish. That is go without powered technology. Now, for you, you need more than a solar panel (and likely more than 30W, but that is a start) - you need a battery or set of batteries to store the collected power. 20Ah might do. You need an inverter to power things. For that, likely a 300W will do. For a TV, go shopping, and look at the labels on the back of the TVs. I just bought a 24 TV rated at 40W. If you get a 9 LED TV, it may be likely you can run that directly from battery, for many have separate DC brick supplies. With those, you can make a cable to power it directly from a 2V or so battery, if the supply can make 2 to 5V. Depending on your provider, you may be able to get a mini-decoder which uses a separate brick or wall supply, which means the decoder likely can be directly battery powered. Such a decoder may draw less than 20W.
- Q: Can solar panels be installed on a deck or patio?
- Yes, solar panels can be installed on a deck or patio. However, it is important to consider certain factors such as the structural integrity of the deck or patio, the amount of sunlight it receives, and any regulations or restrictions in your area. Additionally, it is recommended to consult with a professional installer to ensure proper installation and maximize the efficiency of the solar panels.
- Q: how to build a solar panel
- Search Yahoo Answers or the internet first, this question is common. It is possible to build a solar thermal panel, to heat either water or air. You can just search YouTube to see how people did it. Try searching solar water heater. If you build a photovoltaic (solar electric) panel on your own, it will only be good for demonstration purposes. The homemade type I've seen produces only microamps of current - not even enough to run an iPod. Be wary of sites advertise you can make your own panel for less than $200 (or some figure), and try to sell you the plans. This is the same information that is posed on other sites for free.
