Polycrystalline Solar Panel 250W Hot Selling Made in China 4.FAQ:

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）What is your size for each module? Can you tell me the Parameter of your module?

We have different series of panels in different output, both c-Si and a-Si. Please take the specification sheet for your reference.

（3）Can you provide the peripheral products of the solar panels, such as the battery, controller, and inverter? If so, can you tell me how do they match each other?

Actually we are only manufacturer of solar panels, but we could try to source them for you in China if you need. We could provide you an optimal system design to instruct you how to install.

（4）Do you have the CE, TUV, UL Certification?

We’ve already passed all the tests, and any certificate is available.

（5）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.

Q: My home uses an average of 2400 kW per month (28,800 per year.) How much can I expect it to cost to install solar panels of this amount? (It is not my intention to go off of the electric company's grid. I would like to generate what I can / possibly sell back extra power)What quot;hiddencosts are there? What is the average life of them?What is the quot;best(cost effective and green) solution / approach?(BTW.... I am in southern LA if that makes a difference)Best answer will go to clear answer WITH links/resources to back it up!)THANKS A MILLION!!! I hope you have a safe and happy holiday season!!!: Power inverter to change 2VDC panel power to 220VAC House power. (~$600) You are also going to need various switches and a meter to keep track of how much you are sending back to your power company. Final answer... Expect to pay ~$7,000.00 with installation by a qualified electritan.

Q: I am fairly new to the solar panel scene, and am eager to try to set one up myself instead of buying a kit. I am looking for a solar panel that puts out 00 Watts or more, and can produce more than 20 volts. Thanks: a cheap one that doesn't burn up

Q: What controllers and all that stuff do I need for these solar panels. Oh and the the batteries will be rigged up to a big electric motor so please leave information on how to wire the batteries to the motor...THANKS!!! 0 POINTS!: See answers to your previous questions!!

Q: Can solar panels be installed on churches or religious buildings?: Yes, solar panels can be installed on churches or religious buildings. In fact, many religious institutions have embraced solar energy as a sustainable and cost-effective solution to reduce their carbon footprint and lower energy bills. Installing solar panels on churches not only aligns with their commitment to environmental stewardship but also allows them to set an example for their community by promoting clean energy and sustainability.

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: Ok so I am planning on buying a solar panel. I am doing it to possibly sell the energy that it stores. It is a 20 watt panel so I am just wondering if every week or month if I sold that energy that it stored would make me a good profit. I am not hoping for thousands of dollars a month..just like 00? The solar panel cost me $,00 so if so, how long do you think it would take to make good profit. Also, how much would I make every week or month?: I will give you the tools to answer your own question. Here is the solar resource map: rredc.nrel /solar/old_data/nsr... Use it to look up the hours of peak equivalent sunlight per day in your area. For example, let's say it's 5 hours / day. Then per year you get 365 x 5 = 825 hours of sun Your panel is 20 watts, or 0.2 kW So the energy produced per year is 825 x .2 = 383 kWh You'll have to use the proper numbers for your own area, of course. Anyway, you can take that 383 kWh and determine how much it would cost at local electric rates. Never know, on some islands, it's $.00 per kWh. Check with your local electric company for rates.

Q: What is the working principle of solar panels?: the inorganic salts such as gallium arsenide Ⅲ-Ⅴ compounds, cadmium sulfide, copper indium selenium and other multi-compounds as the material of the battery;

Q: what are the main minerals that are used in making solar panels. and where in the world are those minrelas usually found: Not minerals. Elements. Silicon. Found everywhere. Group III elements for doping. Group V elements for doping.

Q: I am going to be building green in the next couple of years and i need an idea of how many solar panels i need in addition to a wind turbine to sufficiently handle a workshop, house, green house, etc. and what the approximate cost will be.: I think Brian's answer was perfect for the US, but in the UK, with very high gas and oil prices, we would also look at hydrogen production from the wind turbine instead of a battery store, where excess capacity could be used to heat the house or potentially act as a car fuel. Alternatively we would look to selling back excess electricity to the grid.

Q: Hello,What do you all think about the future of solar panels and what role they will play in the near future. There is tons of money being dumped into the industry and demand is slowly rising. Also do you have any favorite solar links to get more info about them?: Well, it's true that solar panels aren't exactly the new invention. However, solar technologies keep improving all the time. Just like computers used to be super rare and hard to get, but right now almost everyone has a PC or a laptop. Same with solar panels, soon they will get a lot more popular. Even people like Bill Gates are interested in solar solutions, here, take a look:
