1.Product Description
We Offer the mono solar panels 250W 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:Is there a free site or resource that will teach you how to do this? Hopefully step by step and tells you how to buy all the parts ect?Which is the best resource for sale earth4energy, homemadeenergy, ect? Do they actually work and also as well as those which are professionally done?They say it will cost under $200 for a panel, but how much will this panel actually produce I mean how many panels would you have to make to produce 00% of your homes energy?
- I have no idea the out put of the panel you plan to make, but $200.00 will not even come close to power much. You don't say whether you want to power your house straight from the solar panels (not possible, because the sun doesn't shine 24/7). That being said,you will need a very large array to power your house,going to battery's to inverter to get AC power. Your initial cost would be around $25000,00, but you might be eligible for a tax rebate and maybe a rebate from your state and power company. There is a lot more to be said on the subject,but this is enough to either get you started or discouraged.
- Q:Can solar panels be installed on a data storage facility or server farm?
- Yes, solar panels can be installed on a data storage facility or server farm. In fact, many data centers and server farms are now incorporating solar power as a sustainable energy solution. By harnessing solar energy, these facilities can reduce their reliance on traditional electricity sources and lower their carbon footprint. Installing solar panels on such facilities not only helps them achieve cost savings in the long run but also contributes to a more environmentally friendly operation.
- Q:How do solar panels affect the resale value of a property?
- Solar panels can have a positive impact on the resale value of a property. Studies have shown that homes equipped with solar panels tend to sell for a higher price and at a faster rate compared to homes without solar. This is because buyers are increasingly interested in energy-efficient and sustainable features. Additionally, solar panels can help reduce energy costs, making the property more attractive to potential buyers.
- Q:I remember hearing somewhere that solar panels may attract light rays away from plants thus having a potentially negative effect on the plants. I can't remember where I heard it but I'm curious if there is any truth to it.
- Solar panels only intercept the light that hits them - they can't attract light rays. So, if you had your panels mounted on the ground, the area in shadow behind the panel would receive less light, making it more difficult for some plants to grow there. This would only be a problem if we start seeing massive solar farms appearing. They could potentially displace farmland or natural habitats in some of the sunny areas of the world. A panel on a roof, however, would only stop light hitting your roof tiles - no great loss!
- Q:Hi, wanting to set up the most basic solar panel system for a cabin in the woods that has enough power to recharge four 2V car batteries during the daytime (i am assuming; we want to run a mini fridge maybe a stove and a few lights at night off the batteries and be able to run it all just off solar during the day) It also needs to be able to power some simple tools during the day... Experience would be absolutely amazing since alot of the info on solar paneling is either really dumbed down, or ridiculously confusing.As of right now I am looking at a 3 panel (45watt in all) solar kit that needs a 300w inverter.... is this sufficient for my power needs? I am just a little perplexed, thanks so much!
- If okorder / If the minifridge is one that plugs into 2 volts, that should be okay. Anywhere you can eliminate the inverter will help. Such as converting the stereo over to 2 volts. The nominally rated panels should be mounted at an angle to maximize the solar aspect/exposure. Essentially your lattitude plus 2 degrees for simplicity. If you add 60 Watts in panels you will do much better. Your 3 panels when installed correctly will actually yield over 5 Watts each panel at midday. If you do not achieve that, something is wrong in either the wiring, or a panel. It translates to about point2 Amperes to point5 Amperes at midday. If wired in series for 36 volts, the total current output will be same as a single panel (nominal 5 Watt), but at a higher voltage. If wired in parallel, you achieve the 45 Watts at nominal 2 volts. Watts is voltts times Amps. Also converting your tools over to run off the 2 volts will help, Or charging your tool batteries off the 2 volt buss. There are buck/boost circuits that would be capable of charging the common 4.4 and 8. volt tools out there.
- Q:Do LED lamps ever go bad?What's the life expectancy of solar panels?
- LED's 6 years or longer
- Q:Can solar panels work at night?
- No, solar panels cannot work at night as they rely on sunlight to generate electricity.
- Q:How many kilowatts? Would it be enough to power my electric heat?Does one panel cost about $2000.?
- I doubt it'd supply your heat. Anything involving electric heating uses tons of energy. Also, keep in mind that you don't just need a panel but also a DC to AC converter.
- Q:Can solar panels be installed in areas with high wind speeds?
- Yes, solar panels can be installed in areas with high wind speeds. However, it is important to ensure that the solar panel mounting systems are designed and installed properly to withstand the strong winds. This may involve using appropriate mounting techniques, securing the panels firmly, and considering the orientation and tilt angles to minimize the impact of wind resistance.
- Q:Can solar panels be used to power a swimming pool?
- Yes, solar panels can be used to power a swimming pool. Solar panels can generate electricity from sunlight, which can be used to power pool pumps, heaters, and other equipment required for pool maintenance and operation.
