Q: Can solar panels be installed on schools or universities?
Yes, solar panels can be installed on schools or universities. In fact, many educational institutions around the world are increasingly adopting solar energy systems to reduce their carbon footprint, lower energy costs, and provide hands-on learning opportunities for students about renewable energy. Installing solar panels on schools and universities can not only help them become more sustainable but also serve as a powerful educational tool for students and the broader community.
Q: I really would like to have my own solar panel, but i don't know how. Most of the panels i have looked at are for car batteries but i'm not sure how this would be able to be transfered into electricity. I'm looking to power things like lamps, a stereo and various chargers for phones and ipods. Please explain to me how i could adapt a solar panel to my uses. Thank you.
Sounds okorder .. I've seen the particular device listed there. While the lamp is mediocre for an LED light source, the panel is excellent - real polysilicon wafers, in an aluminum frame. Same construction as the kind of panels in commercial installations.
Q: in the afternoon sun heat increases to high level due to which the panels heats up very high now my question is this heat will effect the panels life time and will damage the panels or not ??
Most experts believe solar electric modules have a lifespan of at least 25 to 30 years and most manufacturers provide a warranty for this period. However, the truth is that we don't really know for sure since most modern solar panels have not been in existence that long. Many experts believe the actual number could be much higher, possibly as much as 50 years. What is very clear is that solar modules are extremely durable and lose very little of their energy generating capacity over time. From: bit.ly/tpTfK
Q: please help me
Hint: It's behind the foreground.
Q: I'm wondering if the cost of the panels and equipment have come down enough to make them viable in areas like Seattle or Vancuver for example.
Take okorder /.. You need to keep in mind that as long as you are renting your electric from the public utility you are doing just that and renting. You can resale the solar electric system if you move or if you just want to sale it and get some of your money back if not 20 % extra. Then all the years you used the system was all free electric. So it is already viable as you put it. Anything other then buying a system would not be. Here is a thought. The housing market slumped and if you paid 50K for your home it is now only worth if you can even sale it about 00K. Not worth the money but people are still buying homes even if they are not worth what they are being sold for. And then the cars and trucks people buy will never pay for them selfs but people still buy them and spend extra the more wasteful the car is. So why does solar have to pay for it's self or prove it's self? It has many times over but because you can't drive a solar panel drunk and party out in the bars with it is is not worth the money. I guess the is just being human and a double standard. What about the big up front cost of solar? I remember a 20% up front cost when I bought my home and my car and it is the same 20% or less for a solar loan. Plus the value of solar is going up not down like with homes and a car is not worth but half what you paid for it the minute you drive it off the car lot. I can only see good from solar un like other things we buy.
Q: I have seen quite a few different websites that talk about building your own solar panels for around $200. I wanted to know if anyone has had any experience with this before I decide to try it myself. It would be very helpful to know what I can expect from such an inexpensive setup; what kind of electronics or appliances would I be able to power. Realistically what can I expect from a $200 setup, and what would I need to power say a whole bedroom (clock, regular sized TV, PC, ext.).
I okorder / You will also need to purchase at least 2 deep cycle 6 volt batteries and a 000 watt inverter. Depending on your usage you might need to add more batteries and or another panel to you system. Hope this helps.
Q: How do solar panels affect the property's overall sustainability?
Solar panels can significantly improve a property's overall sustainability by harnessing clean, renewable energy from the sun. By generating electricity without emitting harmful greenhouse gases, solar panels reduce the property's carbon footprint and help combat climate change. Additionally, solar panels can lower energy bills, increase energy independence, and potentially provide a source of income through net metering or selling excess electricity back to the grid.
Q: i also need to know how does a solar panel work
solar panels work in an interesting way. light is absorbed by each solar cell, and light 'photons' bump into electrons to produce 'voltage'/power. the process is naturally called the 'photo-voltaic effect'. the loose electrons are captured by an electrical conductor in the solar cell (usually made of silicon) and a circuit is completed ... solar panels may generate more power than is actually needed. this extra power is simply stored in lead-acid batteries (they store upto 000 watts). read more about it here...
Q: Are there any restrictions on installing solar panels in certain areas?
Yes, there may be restrictions on installing solar panels in certain areas. These restrictions can vary depending on local regulations, homeowner association rules, and building codes. Some areas may have permit requirements, aesthetic guidelines, or zoning restrictions that limit the placement, size, or visibility of solar panels. It is important to research and comply with these regulations before installing solar panels in any specific location.
