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:Hello from SO TX.. I would like to know if anyone out there has SOLAR PANELS on their home?I have a 850 sq ft. house. I called Austin to a company that offers panels and installation. The cost $8,000.00, for 0 panels . The rep said we would save about 2 to 25% on our electric bill /mo. We use approximately 980 kw/mo. Our bill is around $40.00 / mo...I really don't think that's a good enough savings. We figure it would take 25 years to recoup our investment.And where we live in TX it does not offer any incentives. The gov. allows you a $2000.00 tx break.
- $8,000 invested at 5% interest would pay you $900 per year for the rest of your life. If you spend $40 per month and would save 25% of that, you would save $420 per year. To be fair, the savings would creep up with the electric rates but this would be off-set by maintenance cost and equipment attrition.
- Q:The intensity of sunlight at the distance of the Earth's orbit is 380 W/m2. An Earth-orbiting satellite has a solar panel that measures .35 m by 4.86 m, which converts solar energy to electrical energy with an efficiency of 26%. In one hour, how much electrical energy does the panel produce? Assume that the satellite's attitude control jets keep the panel oriented perpendicular to the incoming sunlight.
- 380 W/m2. An Earth-orbiting satellite has a solar panel that measures .35 m by 4.86 m, which converts solar energy to electrical energy with an efficiency of 26%. In one hour, how much electrical energy does the panel produce? 380 W/m? x .35 m x 4.86 m x 0.26 = 2354 watts energy is watts*time E = 2354 watts x 3600 sec = 847472 Joules or, E = 2354 watt-hours
- Q:Can solar panels be used in off-grid systems?
- Yes, solar panels can be used in off-grid systems. Off-grid systems are designed to operate independently from the electrical grid, and solar panels can generate electricity from sunlight, making them a reliable and sustainable source of power for off-grid applications.
- Q:Can solar panels be installed on convention centers or event venues?
- Yes, solar panels can be installed on convention centers or event venues. In fact, many convention centers and event venues have already started adopting solar energy systems to reduce their environmental impact and save on energy costs. The large rooftop spaces available in these venues provide ample opportunity for installing solar panels and generating clean, renewable electricity.
- Q:How do solar panels affect the roof's structure and integrity?
- Solar panels can have some impact on the roof's structure and integrity, but they are designed to be lightweight and installed without compromising the roof's stability. Properly installed solar panels distribute the weight evenly, reducing the likelihood of any structural damage. Additionally, solar panels can help protect the roof by shielding it from the elements, potentially extending its lifespan. However, it is crucial to consult with a professional to ensure proper installation and minimize any potential impact on the roof.
- Q:I was watching an idiot abroad, and I saw a family that lived in tent like huts, with no plumbing. And they had a solar panel, now if they can afford it, I know I can. Where do you get cheap ones?
- Guide okorder /
- Q:Need solar panel info with dimensions and also the total cost of the whole equipment for setting up of the required solar panels for a 2-story home
- There are many, upon many variations of equipment needed for a complete solar home. I would call several contractors in your area that deals with it and get estimates. You have to look at what your wattage diet is at your home. How many watts are you using for your AC and heat. Which can vary by age, efficiency, insulation of home, etc. Look at your electric bill for a normal summer month and a normal winter month, then estimate your heating and cooling (Sometimes can be as much as 70% of the bill). You will see on your bill your toal kilowatt hours. ( Kilowat = 000 Watts) Solar systems can start as low as $2.00/watt, but can rapidly approach $20.00/watt depending on the difficulty of application etc.... Here is the great thing, in many areas of the country there may be rebates from the county or state. And what you don't use can be fed back into the grid, and you get paid for it. But as always - Call a quailified contractor and get the right system for your home.
- Q:can i put a solar panel on a projector. if nt wat is a low energy projector that i can watch movies and play games on
- Solar panels put out DC voltage, like a battery. The projectors that plug into the wall require AC voltage. Unless you got a travel projector that plugs into a cigarette lighter (does that exist?), you would need to convert the DC power from the solar panel to AC for the projector with an inverter. And if you want to use it when the sun isn't shining, you'd need batteries to store the power.
- Q:Hey was looking at a 5 watt 2 volt solar panel and was wondering if it'd be enough to power a regular light bulb. Also need to power a 5volt 6.5 amp pump for at most a minute at a time. So basically if I had this panel would I be able to plug a lamp into it and have it light for 5+ hours at a time with the possibility of running the pump? If not what size panel would I need?
- The specifications you give say the solar panel produces 5 watts at 2 volts (DC) so that isn't enough voltage to power an ordinary (20-volt) light bulb. You could get 0 of these panels and connect them in series so they put out a total of 20 volts and the total power available would be 50 watts. The panels would light the bulb that way, provided the bulb isn't over 50 watts and you can afford the panels. A panel does provide enough power for a 2-volt car light bulb less than 5 watts. However, the maximum current you can get from these panels is .25 amperes (5 watts divided by 2 volts = .25 A.) This isn't enough power to run your pump which takes 6.5 amperes - at 20 volts, that would be 780 watts. Another thing to check is the pump motor; many electric motors are designed to run on AC only and will be damaged if you try to run DC through them. Remember solar panels produce DC so the raw output from a panel will not work on an AC motor.
