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: Can I add more solar panel let say up to 200 watt and adding two 2 volts battery using the same charges controller and power inverter?
- If you put a black panel on the ground or on your house and don't connect it to anything, it will absorb solar energy (heat) during daylight and release it at night (radiation). Not exactly. Assuming the black panel establishes an equilibrium temperature, it's going to be losing exactly as much heat as it's receiving during the day. Some will radiate out into space, some will conduct or convect into the atmosphere. As a wild guess, maybe 50/50. If you hook up a solar panel in the same place but hook it up to batteries, charge the batteries during sunlight hours and using that energy to electrically heat the home at night. The panels will absorb solar energy during the day but will convert that to electrical energy in the batteries instead of radiating it back into space at night. The panels are only about 4% efficient, so it's the same situation as the pure black panel for 86% of the energy. The remaining 4% will get stored in the batteries and then converted to heat at night. That heat will eventually leak out of the house and warm up the Earth a tiny bit. I think it's much the same situation either way. With the black panel the energy gets radiated / conducted/convected right away. With the solar panel a small percentage is stored and not so much is radiated, mostly conducted and convected. You're partly right as a black panel is going to radiate more into space than a house. But you're taking about maybe some day about 4% of % of the differening radiation/convection/conduction fraction, of the Earth's surface area. Probably not significant.
- 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: If a solar panel is a .5kW system, what length of time is it putting out that much power? Every hour?
- I think it refers to the maximum power it is capable of. Of course, it won't really have this output because it's energy output (kWh) is dependent on it's energy input...
- Q: Can solar panels be used in cloudy regions?
- Yes, solar panels can still be used in cloudy regions. While solar panels are more efficient in direct sunlight, they can still generate electricity in cloudy conditions. Clouds diffuse sunlight, but some sunlight still reaches the solar panels, allowing them to produce power. However, the energy output may be lower compared to sunny regions.
- Q: Can solar panels be installed on airports or transportation hubs?
- Yes, solar panels can be installed on airports or transportation hubs. In fact, many airports and transportation hubs worldwide have already adopted solar energy systems to power their operations and reduce their carbon footprint. Installing solar panels on these facilities not only helps generate clean energy but also provides an opportunity for sustainable and renewable power sources.
- Q: The battery is 9ah and the solar panel is 20w
- Yes, certainly. So long as the solar panel's voltage exceeds the voltage of the battery (which is probably going, certainly if it can be a discharged battery, which is lower than 2 volts), then it will recharge the battery. Additionally, a 2 V solar panel can produce bigger than 2 volts. Nevertheless, the rate of charging is more likely to be depdendent on the availabilty of daylight. And of course, the better the capcity of the battery, the longer it takes to cost.
- Q: What are the supplies needed in a solar panel field, i know there are the panels. But what about batteries, and converters. Possibly other things, and how many will i need, for a certain amount of panels?
- There okorder . I think you can find lots of info on the internet. I hope this helps you get going.
- Q: Can solar panels be used to power a construction site?
- Yes, solar panels can be used to power a construction site. They can provide a clean and renewable source of energy to run the equipment and machinery needed for construction activities. By utilizing solar power, construction sites can reduce their reliance on fossil fuels and lower their carbon footprint.
- Q: Can solar panels be installed on a community center or social gathering place?
- Yes, solar panels can certainly be installed on a community center or social gathering place. In fact, these locations are ideal for solar panel installation as they often have large roof spaces that can accommodate a significant number of panels. Solar energy can help power the community center, reducing electricity costs and environmental impact, while also setting a positive example for the community in terms of sustainability and renewable energy.
- Q: are there solar panel that work without the sun?
- Yes and no, all solar panels can work without the sun but they mainly would not work without sunlight.
