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:Say if i had a 2KW system is thtat just one big solar panel or does the whole system have little solarpanels together.?
- Solar panels are arrays of individual solar cells connected in series and parallel, and.. A high quality, monocrystalline silicon solar cell, at 25 °C cell temperature, may produce 0.60 volts open-circuit (Voc). The cell temperature in full sunlight, even with 25 °C air temperature, will probably be close to 45 °C, reducing the open-circuit voltage to 0.55 volts per cell. The voltage drops modestly, with this type of cell, until the short-circuit current is approached (Isc).
- Q:I want to plug my solar system battery bank into my transfer switch on my cabin when not using a generator. The transfer switch will handle 220 volt from my generator. How do I get a 220 volt inverter that runs 60 hz or do all of them run 50 hz.I see plenty of 20 volt 60 hz. I'm at the point of needing to order one and I'm not sure.

- Q:How does the snow cover get removed from the panels?
- Green energy magically makes the snow transparent. The more I learn about solar and wind, particularly selling excess power back to the utility, the less sense it makes. You'll have noticed, perhaps, that there was no way to store the power from the panels for when it's really needed.
- Q:Main questions: How can I work out the efficiency of a solar panel and how can I work out if the panel is relatively cost-effective? Also what type of solar panels is considered most effiecient?Let's assume that all relative values are available.Secondary question: What type of safety regulations and licenses are required to be fulfiled in order to import solar panels into the EU from non-EU countries?
- The manufacturer of any serious panel should be able to provide an efficiency. That will be the STC power rating of the panel, divided by the area of the panel, divided by 000 w/m^2. But the more interesting figure is cost effectiveness, as you say, which is nothing more than cost per watt for the same class of panels. Most applications are limited by money, not by area.
- Q:We are considering getting solar panels for our home just south of Birmingham, AL. We know a little and are trying to educate ourselves the best we can. But we are having a hard time finding anyone around this area. We have done the yellow page thing, and some quot;green places around town. But to no luck.....
- Any electrical contractor could likely install them, and there are several Internet businesses that sell solar panels. You likely have no place there to get the kind of large panels you need for a house. Look at your local regulations. Your utility may not allow grid-tie, so you may have to set up an off-grid system with batteries and use separate wiring or a transfer switch. One thing a lot of people neglect is hail protection. In Birmingham, you're likely to have large hail (larger than golf ball size) every couple of years in the spring. You need to work out a way of covering them in advance of severe weather. Most panels will take up to golf-ball size hail with no problem. DK PS, I've done this myself, and have considerably more information. Email if you're interested.
- Q:i am looking at installing some solar panels and a wind turbine for electricity.has anybody got one of these and how much do they save you?thanks
- I don't have one myself, but some of my neighbors did. They said that wind is cost effective. The equipment will make money over the lifetime of the equipment. When they did the calculations for solar, the savings did not cover the cost of the equipment over its lifetime. They were very happy with their wind turbine and several months even got paid by the power company for putting energy back into the grid. However, this was when I lived in Kansas. Wind does matter on location.
- Q:How hard is it to install solar energy panels on your house? Is this a reasonable way to produce 00% of your house's energy? Is there any danger?
- The panels are relatively easy to install. The batteries and the inverter tend to be heavy and you will need many people or mechanical assistance. You are talking about high current DC thus if you touch the wrong wires it's CC (Cancel Christmas - Rescue Squad Term). You also also dealing with lead acid batteries so they need to be well ventilated or we have another CC situation. Should you have a short, the batteries will overheat and explode projecting sulfuric acid... And the best part is when all is said and done, you are only paying twice to three times the cost for the electric over the life of the system as compared to buying the electric from the power company.
- Q:Can solar panels be installed on a barn or agricultural building?
- Yes, solar panels can be installed on a barn or agricultural building. In fact, these structures often provide ideal conditions for solar panel installation due to their large, unobstructed roofs and proximity to open spaces that receive ample sunlight. Installing solar panels on barns or agricultural buildings can help farmers and landowners generate renewable energy, reduce electricity costs, and contribute to a more sustainable future.
- Q:when we say a solar panel has 20% efficiency, do we mean that it converts 20% of sunlight reaching it into electricity or that it converts 20% of visible light(which is only 7% of sunlight) into electricity?
- That portion of the sun's light to which it responds, of which it converts 20% to electricity.
- Q:Can solar panels withstand extreme weather conditions?
- Yes, solar panels are designed to withstand extreme weather conditions such as high winds, heavy rain, and hail. They are made of durable materials, including tempered glass, that can endure these elements without significant damage. Additionally, solar panels are tested and certified to meet industry standards for performance and durability, ensuring their resilience in various weather conditions.
