Characteristics of Polycrystalline Solar Panel

I Solar Cell : High efficiency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.

II Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.

III EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.

IV  AI frame: Without screw, corner connection. 6 holes on the frame can be installed easily.

V Junction box: Multi function junction box with water proof.

VI Long lifetime: ≥25 years; Less power decrease.

VII Good performance of preventing from atrocious weather such as wind and hails.

VIII Resisting moisture and etching effectively, not effected by geology. .

 

Standard Test Conditions of Polycrystalline Solar Panel

The opto-electrical specifications shown below are stabilized values being measured at Standard Test Conditions of multicrystalline silicon Solar Panel, Irradiance: 1000W/m2, Spectrum: AM1.5 at 25°C, The info below is subject to manufacturing tolerances. Where appropriate minutes of measurement are available and are used for the dimensioning of the installation.

Currently,We have 250w-300w solar panel stocks in Both West and East Coasts made in Vietnam,India,Korea,Malaysia and Japan.Meanwhile,we also arrange production line in Wisconsin,USA.If you're interested,please contact us soon.

Thanks for your time.

 

Q:How do solar panels affect the property's operating costs?
Solar panels can significantly reduce a property's operating costs by generating clean and renewable energy, thereby reducing or even eliminating the need for traditional electricity from the grid. This results in lower monthly utility bills, as well as potential incentives such as net metering or feed-in tariffs that allow excess energy to be sold back to the grid. Additionally, solar panels require minimal maintenance and have a long lifespan, further contributing to cost savings over time.
Q:How do solar panels affect wildlife?
Solar panels can have both positive and negative effects on wildlife. On the positive side, solar panels can provide a habitat for certain species, such as birds or insects, as they can create shaded areas or serve as perches. Additionally, solar farms often have vegetation underneath or around the panels, which can attract and support a diverse range of wildlife. However, there are also potential negative impacts to consider. Large-scale solar projects can disrupt or destroy natural habitats, leading to the displacement or loss of certain species. Additionally, solar panels can pose a risk to birds and other flying animals if they are not properly designed or installed. Glare from the panels may also impact wildlife behavior or migration patterns. Overall, it is important to carefully plan and manage solar installations to minimize any negative impacts on wildlife while maximizing the benefits they can provide.
Q:Can solar panels be used in areas with high levels of UV radiation?
Yes, solar panels can be used in areas with high levels of UV radiation. In fact, they are designed to withstand and harness UV rays from the sun to generate electricity. The materials used in solar panels are specifically chosen to endure high UV exposure, ensuring their efficiency and longevity even in such conditions.
Q:i've heard that solar panel batteries have to be replaced withen 5-0 years. how much do solar panel batteries cost? please include sources!
Depends on how big a battery you want and what technology. A lot of people use lead-acid batteries (rather like car batteries) and they do need replacing and 5 to 0 years isn't a bad estimate. However, the lead and lead salts content can easily be recycled into new batteries so its not as bad as it may seem.
Q:I recently got into solar panels, I have little background in electronics but I have done a little electrical work in the past and just want to make a small 36 cell panel to power a 2v battery that would run my a small tv (9 inch) and PS3 for a few hours every night. I have been looking up on how to do it before I get in over my head and I have a few questions.... After you solder all of the cells together then what? Do you hook all of the rows of cells together somehow? Can you connect them straight to a battery? After you hook to the battery do you hook up a power inverter to get the 2 AC plugs that would be needed? Thanks in advance for any help....
I'll add a few comments to Teelo's It may not be good to connect the assembled solar cells directly to the battery. When there is no sun I think it will drain the battery. I'm pretty sure all circuits I have seen have a reverse polarity diode in series. (unless Teelo knows for sure). Hmmm Reminds me that I have some bare solar cell elements from when Motorola was making them. I used some to power a small radio controlled car. I do know that all good applications have a regulator to make sure the charging is done properly
Q:Hi.How efficienent are solar panels? I mean, suppose we install a kw panel.. Wil it produce 5kw in 5 hours of good sun light?Or like if its 80 percent efficient, wil it produce 4kw and so on.Also, do the chinese solar panels give the same results as compared with panels from other countries?I live in india, so we get plenty of sunlight during the day.Thanks
The panels themselves efficiency are 5 to 8 percent at converting sun energy to electicity currently.But as what you said above,the conversion efficienc is about 70%,so a KW solar panel can produce 3.5KW in 5 hours,The solar panels of China are compared comparably to other contries.The highest efficiency of 24% is rare,they are not widely avaliable.
Q:Can solar panels be used for air conditioning?
Yes, solar panels can be used for air conditioning. Solar panels generate electricity from sunlight, which can be used to power air conditioning units. By using solar energy, homeowners and businesses can reduce their reliance on traditional electricity sources and decrease their carbon footprint. However, the efficiency and effectiveness of using solar panels for air conditioning may vary depending on factors such as the size of the solar system, location, and energy requirements of the air conditioning unit.
Q:I was looking at thin flexible solar panels as solar panels 500w a option to upgrade a 20w solar panel I have permanently mounted to the roof of a home made camper van.Why I was thinking flexible is at just 2mm thin they can be glued down and being flexible they will follow the contour of the rounded shape of the roof of my camper (boxy standard solar panel spoils the lines a little)Another reason is no glass to brake when traveling on dirt tracks(though I am surprised mine hasn't broken yet after thousands of km on corrugated dirt roads). Finally there is a weight saving at only /3 the weight or less then a standard glass panel.There are different grades of flex PV some of the more expensive ones are very flexible with extremely thin backing at around .5mm The ones I was looking at are cheaper and at around 2mm with a thin flexible aluminum backing.$250 is about the going rate for 20w OKorder job. Below is a pic of a smaller one 60w or so.Has anyone had any experience with them?

Q:i want to build a stationary model of a solar panel and i dont know if it is going to be too simple or not i also want ideas to make it betterplease criticism is allowedmy idea was to make a case, just like a real solar panel, and take plexiglass to make it. i want to add some models of photovoltaic cells that look like they are in a solar panel . i want to add the fake shoulderings as well . i want to make the case openable by hinges.i would like some of your thoughts and ideas to help me .thx

Q:3.8 volts is required to fully charge a battery. But at 3.8 volts, the battery can be overcharged without the use of a controller correct? What if I don't care if the battery is fully charged? In the case of our family boat, I just installed a new radio, so I'm a little worried about power consumption. So now for the real question; If I hook a 2 volt panel to the batteries, do I need to worry about overcharging them? Or will the batteries stop the charging process once they reach 2 volt?I built the panel myself, it's 8 volts at 3.5 amps open circuit. I have tabs at every 3 volt increment on the panel so that I can use less voltage than 8 if I want to power something directly, (ex:2 volt radio)So I'm using the 2 volt tab at 3.5 amps(approx) for a total of approx 48 watts
It is cheaper to have a solar regulator to extend the battery lifespan. A lead acid battery can vent hydrogen if charged too much and run out of electrolytes. The battery would cost more than a $30 5 amp solar regulator.
