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: If my school uses 88240kWh of electricity per month and I have 000 50W solar panels running for 6 hours a day, does it mean it will take 88240kWh / {{[(50W x 3600s)*000]/000}kWh x 6} number of hours to generate that much electricity (88240kWh)?
running six hours a day doesn't mean much. You need to look at the solar insulation charts for your school's geographical location to come up with a better factor. The easiest number for you to use is sun hours. For example, Washington DC averages 4.23 hours. Do a Yahoo search for sun hours and you should find lots of charts. Solar panels rated at 50W give this output at full sun near noon at full brightness (no clouds). The sun hour factor makes it easy to find the equivalent number of full brightness hours. So, using Washington DC as an example you have: 000 panels * 50W * 4.23 sunhours/day = 634kWh a day on average. You state your school uses 88240kWh/month which is 6274kWh a day. This would mean you need ten times more solar panels since there is no way to get more daylight. Be careful to put in all the units in your formula and cancel them out to make sure you don't end up with a nonsense result. The title of the question would be answered as followed: 50W/000 * 4.23 sunhours/day = 0.63kWh/day or 9kWh per month or 228kWh a year. These are annual averages. If you wanted a specific month, you would need the sun hours for that month. Hope this helps.
Q: Are there any fire hazards associated with solar panels?
Yes, there are potential fire hazards associated with solar panels. Although solar panels themselves do not typically catch fire, electrical malfunctions or faults in the wiring, inverters, or connectors can lead to overheating and fire. Additionally, if a fire breaks out in the surrounding area, solar panels can hinder firefighting efforts by creating potential electrical hazards and obstructing access to the roof. Therefore, proper installation, regular maintenance, and compliance with fire safety regulations are crucial in mitigating these risks and ensuring the safe operation of solar panel systems.
Q: How do solar panels withstand harsh weather conditions?
Solar panels are designed to withstand harsh weather conditions through their durable construction materials and protective features. The panels are made with tempered glass that can handle hail, heavy rain, and snow without getting damaged. The frames are typically made of strong aluminum or stainless steel to provide stability and resistance against strong winds. Additionally, advanced solar panels have built-in drainage systems to prevent water accumulation and snow shedding technology to remove snow buildup. These design elements enable solar panels to endure and continue generating electricity even under challenging weather conditions.
Q: Can solar panels be used in developing countries?
Yes, solar panels can be used in developing countries. In fact, they can be a highly effective and sustainable solution for providing electricity in areas where access to energy is limited. Solar panels are easy to install, require minimal maintenance, and can harness the abundant sunlight available in these regions. Additionally, solar energy can help reduce reliance on expensive and polluting fossil fuels, improve access to electricity for schools, hospitals, and homes, and contribute to the overall development of these countries.
Q: OK, so if you put solar panels up on a roof, they are busy turning the sun's energy into electricity. So, does that mean the roof (and therefore the house/structure) stays cooler as well? Or does it still get hot, because . . . I dunno, maybe the panels don't convert all the energy, and the spillover still heats up the building.Any links or URLs to scientific answers would be appreciated, but I don't mind hearing from the Average Joe or (Joelle).
The type depends upon what you want the solar panels to do. Generate electricity ? Heat gain? Makes a big difference. You should probably get a contractor who specialises in solar panels out to at least start your education on this subject or you could throw a lot of money away on something you don't really need or want.
Q: Does San Francisco get enough sunshine to really make solar panels a viable option for creating a self-supporting home? Certainly a wind turbine would be a good source of energy, but what about solar panels? Does S.F. get enough sunshine to justify using solar panels? It's overcast a lot in the Bay Area, are there any solar panels better than others for a climate like this?
PV Solar panels all work the same. There aren't any climate specific ones. There is enough sun in San Francisco to produce energy using solar panels however, the the same panels located in a sunnier area will produce more energy. Depending on the size of your system, you will probably need a few more panels than an area that receives more sun to produce the same amount of energy. But they will still produce energy, even on overcast days. The solar installers will make all the calculations to determine what size system you will need to produce as much energy as you want. In California, you don't want to produce more than you consume in a 2 month period because currently, you are not able to sell your excess credits back to PGE after your 2 month cycle. Your system will cost more to produce the same amount of power than my system because I have less overcast days than you do. You will have to make the decision if the cost is worth your while. I expect my system to be totally paid for in around 8-9 years, working in the cost of inflation for electricity. After that, I will be paying nothing for electricty for as long as I stay in my house.
Q: Can solar panels be installed on a military base?
Yes, solar panels can be installed on a military base. In fact, many military bases around the world have already implemented solar energy systems as part of their efforts to reduce dependence on fossil fuels and increase sustainability. Solar panels can be installed on rooftops, parking lots, or open grounds of military bases to generate clean renewable energy.
Q: Can solar panels be used in remote areas with no access to the grid?
Yes, solar panels can be used in remote areas with no access to the grid. Solar panels generate electricity from sunlight, making them an ideal solution for off-grid locations where traditional power infrastructure is unavailable. They can be installed in remote areas to provide a reliable and sustainable source of energy, allowing for essential power needs such as lighting, charging devices, and running small appliances even in areas far from the grid.
Q: What is the impact of roof shading on solar panels' efficiency?
Roof shading has a significant impact on the efficiency of solar panels. When the panels are shaded, they receive less sunlight, which reduces their ability to generate electricity. Even a small amount of shading, like from nearby trees or buildings, can lead to a drop in overall panel efficiency. It is crucial to ensure the panels are installed in areas with minimal shading to maximize their performance and yield.
Q: Hello,What do you all think about the future of solar panels and what role they will play in the near future. There is tons of money being dumped into the industry and demand is slowly rising. Also do you have any favorite solar links to get more info about them?
