1.Product Description
We Offer the mono solar panels 250W, 255W, 260W 300W, poly solar panels 250W 260W 300W. You can find different mono solar panels and poly solar panels . We are the professional solar panels solar modules supplier.
Solar panels or modules use light energy (photons) from the sun to generate electricity through the photovoltaic effect. The majority of solar panels or modules use wafer-based crystalline silicon cells or thin-film cells based on cadmium telluride or silicon.
Solar panels constitute the solar array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications. Each solar panel or module is rated by its DC output power under standard test conditions, and typically ranges from 100w to 320 watts. Ground mounted photovoltaic system are usually large, utility-scale solar power plants. Their solar panels or modules are held in place by racks or frames that are attached to ground based mounting supports.

6.FAQ
We have organized several common questions for our clients，may help you sincerely：
1). What’s price per watt?
A: It’s depends on the quantity, delivery date and payment terms of the order. We can talk further about the detail price issue. Our products is high quality with lower price level.
2). Can you tell me the parameter of your solar panels?
We have different series of cells with different power output, both from c-si to a-si. Please take our specification sheet for your reference.
3). 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.
4).Can you do OEM for us?
Yes, we can.
- Q:where I can find solar panel the has 4.8 volts? Like those solar walkway light or something that has 4.8 volts solar panel.Do you think I can get it from home depot?
- The other thing to do is to search for DIY solar chargers for more information.
- Q:And how do you choose the best one for the best price?I saw a 400 watt monocrystalline solar panel
- The polycrystalline solar panel has a longer life-span and has a higher efficiency. What this means is that from the energy that 'hits' the solar panel, more is caught and used to convert into electrical energy. A polycrystalline solar panel will have an efficiency of about 4%. The monocrystalline solar panel has a similar efficiency but the cells are prone to sunlight, so the efficiency drops over the years.
- Q:i am working on a project which requires small solar panels. i am looking for ones about 3X4. is there any way i could get these? and where?
- Thin-film solar panels are a great way to go if you're looking for small solar panels. Thin-film have the advantage of being lighter while a traditional crystalline panel is more efficient so it can produce more power with the same area. With the increasing efficiency of thin-film solar panels, however, they are quickly becoming an excellent option for portable power solutions. If you want crystalline panels instead of thin-film, the DURAlite line is a good example of a portable solar panel that uses regular polycrystalline solar cells. DURAlite panels come in 5, 0, or 20 Watts and they have a 0' cable with a 2-volt car-style socket plug.
- Q:i have this usb solar panel charger i am building and the solar panel is about 2by .5quot;, so i was wondering if a led light can power it, if so will one be good or would i need more? if so how many?
- While I understand Search's answer, because it was also my first reaction, am I wrong in thinking that this is some sort of science fair project, for which you need to power a solar panel indoors as though it were being illuminated by the Sun? The question at least makes sense in that context. Solar panels provide modest power even from room lighting, sometimes calculators are powered by small panels, but that is a tiny amount of current. . You'll probably do better by asking this question (a bit more clearly) over in Engineering. It's not really an Astronomy Space question, though there may be some crossover between the two groups of users. Meanwhile, while some white LEDs can be pretty dazzling to the eye, I don't know how much actual power they are pulling down compared to what you'll need the panel to generate, but I don't see why it shouldn't work. I just don't know how many LEDs you would need. . .
- Q:Are solar Panels worth it, Do they really quot;save moneyon electricity?
- Yes! They will save you money for a lifetime. Imagine not paying for electricity bills every month.
- Q:Can solar panels be used to power a data center?
- Yes, solar panels can be used to power a data center. Solar energy can be harnessed through photovoltaic panels and converted into electricity to power a data center's operations. This approach helps reduce reliance on traditional energy sources and promotes sustainability. However, the feasibility and effectiveness of using solar panels will depend on factors like the size of the data center, available sunlight, and energy requirements.
- Q:My electric bill per month averages 800 kWh per month. I am looking at 65W solar panels. How many panels would I need to make my bill come to zero? I realize I also need an inverter to convert dc to ac.
- There is always a lot of confusion on this question so I built a webpage to show people how to do the math and pick the right system size. Most all public utilities will trade you kWh for kWh and then either settle up with you at the end of the month or every 2 months. So one week you might have all rainy days but the next 3 weeks you have 0 hours of bright sun even in the winter. This means you have no need to put batteries on your system unless you have a lot of power outages. Then you only need a few hours of battery backup power. At most 24 hours.
- Q:solar panels are way too expensive to buy, can they be homemade cheaply? i want at least 500 watts. everyone on the web sells these instructions, but i'd like a link to free info, if it is really possible for a non-sciencey person to make. thank you
- If you want long term working ones then no. I have not seen the web instructions ones, but solar panels that are manufactured are a lot more complex then simple solar panels that you make in your backyard. Also, you need to have some type of turbine or other thing to change heat energy into electrical energy. For a non science person to try and do this and have it work the first time maybe hard to accomplish.
- Q:how much electricity will produce in Kwh by a 000 W solar panel in a sunny tropical area per day (good sunlight at least 0 hour a day)
- Duh - 000 W panel (rated in good sunlight) in 0 hours of good sunlight. Let me see - 0 * 000 = 0,000 wh or 0 kwh. Yup.
- Q:Is it good? ( solar energy)
- Solar power works by capturing photons from the sun and storing their energy in a battery. Solar panels still only capture a very small amount of photons due to technology/distance from the sun/ and probably a number of other reasons. If you wanted to buy a solar panel, you find a company that sells them, send them your electric bill for the past year or so. They calculate the energy restraints, size and additional technical mumbo jumbo. They tell you how much it costs and how much money you could save. Some people might buy a size larger than what they need, in which case they sell the excess energy to your local power company for a few pennies a month(this is usually not very profitable).
