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. .

- Q: I have a cabin that is way out in the middle of no where, it would cost 000's of dollars to get power to it. If I have a 8,000 BTU air conditioner that runs on 25 volts and 5 amps (or 875 watts)How many solar panels will I need to run this during the day, plus charge the batteries to run it all night? How many batteries would I need
- You would need 6 300 watt solar panels, US price around $300 per, And a minimum of 4 batteries. You are going to have major problems only having 5 hours of sun though.I am not sure you could get it to work with only that much sunlight. Along with an inverter and some other controller units. If you live in an area that has some wind, a wind generator would knock it down to where you would only need 2 solar panels and a small 500 watt wind generator. The problem you are going to have is trying to run it all the time. I had an AC that size in my camping van, it took about 20 minute to run two batteries down so low that the inverter started to sound the low battery alert. If I left it running it did ok, and I had an over-sized alternator for it. I had a 50 amp heavy truck alternator. A swamp cooler would be a lot less energy, you could easily recycle about 95% of the water. I know this is the 2st century and this may sound a little nuts, but with only 5 hours of daylight, if you have some trees you could use for burning you could build an outdoor steam engine cheaper and it would charge a lot more batteries in a lot less time. Plus you could run off the steam engines generator for as long as you had a fire day or night. Even a small 55 gallon water tank would give you plenty of head for the steam. You could easily run a 6000 watt generator off of it and have plenty of electricity while it was running. Just a thought, I had to resort to some extreme measures when I bought some Montana land in 2000, it was 6 miles to the nearest utility pole.
- Q: Can solar panels be used in areas with high levels of air turbulence or strong winds?
- Yes, solar panels can be used in areas with high levels of air turbulence or strong winds. However, it is important to ensure that the solar panel installation is designed to withstand such conditions. Proper anchoring and mounting systems, as well as reinforced frames, can help secure the panels and prevent damage or displacement due to wind forces. Additionally, selecting wind-resistant solar panel models can further enhance their performance and durability in such environments.
- Q: For my Product Design Coursework I am designing an environment friendly building according to a clients' specifications. I need to find out the dimensions of 0000 watt solar panels. any help would be much appreciated!

- Q: If you need 9400 watts, 75 amps@ 240V, how many solar PV panels do you need?
- 75 amps @ 240VDC is 8,000 watts.
- 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: Photosynthesis is fairly inefficient, but efficient enough to power all life on earth.
- One of the primary reasons solar cells are made of silicon is that the bandgap energy of silicon happens to be nearly equal to the energy of visible light, which is the major portion of energy emitted by the sun. Therefore, silicon is the ideal substance to fabricate solar cells with.
- Q: I want to know that if I put solar panels in space if Pluto can recieve energy for iPods and television
- Not really. Solar panels operate by sunlight knocking electrons off atoms, and there has to be a particular minimum of light in order to maintain a steady stream of electricity. Beyond Mars, we equip our probes with batteries and generators - because the sunlight at that distance is too weak to generate the electricity needed - so... no. Solar panels on Pluto won't charge anything....
- Q: I found portable solar panels used for boats etc. and was wondering how I could effectly use them for my home instead. If you have used them in the past, please tell how they worked (good or bad).
- Most people think all one needs is some solar panels to make power. It doesn't usually work that way. On a boat it is easy because most boats use batteries and DC power. If all you want to do is make DC power, you will need a battery to hook your portable unit / units to. You can then use the battery to supply power to something that uses battery power. You may need a voltage converter if the device is not 2 volt. To use the power you get from solar panels for AC power like your house has, you need a regulator, inverter, and controller to change the DC output from the panel (s) to AC and then control the power into your electric system. You also need a unit from your electric company installed. A decent minimal solar system for an average house may cost around $5000 - $0,000. It will take many, many years to pay back. For a full-use system with generator, it will probably take $30,000 - $40,000 IF you don't use it for air conditioning. If you live in an area where you have a lot of cloudy days, it will take many, many, many, many years to pay back. The reason everyone isn't using solar power is because it is not cheap and has not been cost-effective for most situations. Most Americans would not like it's inconvenience at times. It is not new science. It is in use many places and well known. It is great for some applications and as fuel and electrical power cost increase it will be used more. Don't believe the media and hollywood. They are not interested in truth. They are just interested in making you believe their way. Study and learn.
- Q: i am very new to the solar world and i need help with some stuff to understand what i need to do.what AH battery should i use? i am planning on getting a 2V deep cycle gel based battery but i want to get the most power for my system so should i use something like a few 00AH in a battery bank system or a bunch or 50 or so amp hour batteries in a bank. also what kind of power am i looking at for the best battery system. in other words what kind of basic appliances like lighting, laptop,space heaters etc can can i run on the selected battery system and for how long? any help would be highly appreciated.

- Q: What happens to solar panels during extreme weather conditions?
- Solar panels are designed to withstand a wide range of weather conditions, including extreme weather. However, during severe weather events such as hurricanes or hailstorms, there is a possibility of damage to solar panels. In such cases, the panels may become dislodged, cracked, or shattered. Regular maintenance and proper installation can help minimize the risk of damage, and many solar panels are built to withstand high winds, heavy rain, and even snow.
