SITE SELECTION
In most applications, the PV modules should be installed in location where there is no shading throughout the year. In the Northern Hemisphere, The PV modules should typically face south, and in the Southern Hemisphere, the PV modules should typically face north. Please make sure that there are no obstruction in the surroundings of the site of installation. Take proper steps in order to maintain reliability and safety, in case the PV modules are used in areas such as: Heavy snow areas/Extremely code areas/ Strong wind areas/Installation over, or near, water/ Areas where installations are prone to salt water damage (*)/Small islands or desert areas.(*)
If you are planning to use the PV modules where the salt water damage may be possible consult with CNBM local agent first to determine an appropriate installation method, or to determine whether the installation is possible?
- Q: What is the average lifespan of a solar panel?
- The average lifespan of a solar panel is typically around 25 to 30 years.
- Q: Can solar panels be damaged by birds or rodents?
- Yes, solar panels can be damaged by birds or rodents. Birds may build nests underneath the panels or perch on them, causing potential damage to the wiring or scratching the surface. Rodents like squirrels or rats can chew on the wires, leading to electrical issues. Therefore, it is important to take preventive measures such as installing bird deterrents or protective barriers to minimize the risks posed by these animals.
- Q: How do solar panels impact wildlife?
- Solar panels have minimal impact on wildlife compared to other forms of energy generation. While there may be some concerns about the disruption of habitats during installation, once operational, solar panels do not emit greenhouse gases or pollutants, reducing air and water pollution that can harm wildlife. Additionally, solar panels typically occupy a small fraction of land and can be installed on rooftops or in areas with limited biodiversity, minimizing the impact on wildlife habitats.
- Q: Photo-Voltaic solar panels are very expensive. Most of a home's energy needs are for heating water, heating and air-conditioning. All of these can be met with thermal solar collectors which are much less expensive. The thermal solar panels would heat water stored in a hot water tank which then can be used as hot water, to heat the home, or as the heat source to a Lithium Bromide Absorption chiller to air-condition a home. With the base line needs met without expensive panels and without inefficient energy conversions, only a small Photo-Voltaic array would be needed for the remaining power needs and since those needs are variable, there would still be power to sell to the grid.
- That sounds good to me. I'm all for any kind of new energy as long as it's renewable and doesn't pollute the environment. I'm even a fan of solar water heating.
- Q: So I want to go completely solar. Do I need the connected solar panels alone for after sundown hours; Do I need something else in order to have energy to run my entire house throughout the night?In other words do solar panels store the energy for after sun-down or do I need other devices to store the energy?

- Q: Can solar panels be installed on a shopping mall or retail complex?
- Yes, solar panels can be installed on a shopping mall or retail complex. Many commercial buildings, including shopping malls and retail complexes, have begun to incorporate solar panel installations as a way to reduce energy costs, promote sustainability, and demonstrate environmental leadership. The large rooftop spaces available on these buildings make them ideal candidates for solar panel installations, which can generate clean and renewable energy to power the complex. Additionally, solar panels can also be integrated into parking structures or canopies to further augment the energy production potential of the shopping mall or retail complex.
- Q: i have a 50 watt 2 Volt solar panel..Will it can switch on directly a car head light on a sunny day??? How much head lights it can support on a bright sunny day??? if its cloudy then can it run a single Head light???? i have no batteries just want to connect a car Head light directly to solar panel.
- It should illuminate two auto headlights on a sunny day, if it really generates 50 watts at 2 V. On a cloudy day, I don't know. It depends on how cloudy it is.
- Q: I have four power packs for solar lights. They have 3 AA .2volt batteries of 2450 mAh capacity installed in series for a total supply voltage of 4 volt maximum for the lights. I want to charge all four packs at once off a single 6 volt solar panel. With the four packs wired in parallel, what capacity output (wattage) panel do I need to charge the batteries in an 8 hour day?
- Each battery pack has the equivalent of only 2450mAh capacity at 4 volts, so for 4 battery packs like that, a total capacity of 9800mAh. Assuming that the solar batteries have no charge left after being on all night, and that day charging time equals night discharging time, the theoretical wattage would be 9800mA times 6 volts = 59 watts. Of course, battery charging is not 00% efficient, so you need more wattage than that. Plus, solar panels are rated at peak output at midday, while at other times of day their output is less than rated. And, the charging in parallel isn't a good idea, because real batteries have different internal resistances, some batteries would become overcharged, while other packs wouldn't get the charge they need.
- Q: i want to how i make solar panels
- DIY okorder
- Q: Ok so i'm writing this research paper on why solar panels are the best way to quot;go greenquot;. I need at least 5-7 reasons why they are good. and a common counterargument that i could defend. I've already come up with incentives and efficiency but i need a few more Please help its very important and worth half my grade
- Actually, solar energy IS a good one. It's something we all need to think about, especially when coal and oil become harder to get. Good luck with your paper!
