Q:Tips for convincing my school to put solar panels on the schools roof?
Installing solar cells cost money. It would swamp the capital spending portion of the school budget. I doubt the school board would put it into the budget because of the cost involved. If they did I guarantee you that, when presented to the voters, they would turn down the budget. If you really want to do something, I suggest a fund raiser, but you are probably looking at raising more than $500,000. Good luck.
Q:A couple questions about home made solar panels?
there are plenty of free sites that tell you how to install your own solar panels. Just google diy solar panels. as to how many panels you need, it depends on what all you're trying to have them run.
Q:Cost of Solar Panels for basement?
If you're really planning on solar energy, don't waste it on your own consumption. The Hydro company pays you for the energy you put back into the grid....the strange thing is, you buy the power back for less than you sold it, so you actually profit on the power you make! look into this. I wired a nice house for a doctor, and although I didnt supply the solar system, I learned of this concept there. The guy who installed her system charged her around $40,000.00 and the system would never be able to run any large portion of their home. They, of course sold the energy to the utility.
Q:Homemade Solar Panels?
The technologies of the photograph voltaic panels is a lot previous any DIY undertaking. you ought to purchase pre-assembled panels and set up them, yet you in addition to mght choose the units to make the DC they generate into the AC your place desires. additionally you will choose the batteries for the nights and the cases while the solar does not shine. photograph voltaic/ photograph voltaic technology does artwork yet isn't a miles less high priced thank you to decrease your reliance on the electrical powered grid as of this time. They fee 2 hands and a leg, and take some years yet to come back on the brink of wreck even on the electrical powered mark downs. Do a seek on the quantity of skill each and every panel will generate and then compute how lots skill you like and what the expenditures are. i think in photograph voltaic skill, yet no longer for somebody place of abode is it sensible. stable success.
Q:how many 45 watt solar panels would I need?
Excellent answer from Server Room above. I notice that you mention 45-watt panels, suggesting that maybe you are considering the kind of kit that comes with 3 5-watt panels. I'd recommend against that, as the type of panel that comes in those kits tends to be optimistically rated, and not durable, either. The best way to go for this sort of thing is to use grid power. Then if you want to offset your usage with grid-tied solar, that can be an independent consideration.
Q:Can we cover up solar panels on our house with regular siding?
I took mine out to prevent any future problems. Covered the holes with plywood.
Q:know about solar panels?
Solar Panels are groups of Solar Modules mounted together. A solar cell is one cell. A solar module is a group of cells mounted in to a sheet A solar panel is a group of solar modules connected together on a rack and normally placed on the roof etc.. as a unit and can be called a solar array. A solar array is a group of solar modules or solar panels all mounted and wired together to form a single unit. Like a battery bank is a bunch of batteries hooked together and the batteries are made of cells. Was that what you wanted to know?
Q:where to face solar panels?
The following links is a sun angle calculator which I find very helpful during my days of doing project about solar panel. The calculator will give you the accurate location of the sun. Solar panel work best when it is directly facing the sun. All you have to do is key in your location details and it will provide you with two most important details: azimuth angle and altitude angle. Azimuth angle is the East angle where the Sun is relative to the South while altitude angle is the tilt angle of the solar panel throughout the day. By using these two angles, you will maximize your exposure of solar panels. However, if you are experiencing rainy or cloudy days, horizontally mounted solar panels is the most efficient.
Q:Designing 3d Solar Panels?
I don't know anything about the 3D thing. You cannot get more energy out, than goes in. Energy will only hit the mirrors. With some loss of efficiency they would reflect a focused beam into the chamber, where with some more losses would reflect it to the solar panels. It would be more efficient just to expose all the panels to sunlight.
Q:how does solar panels work?
Solar panels collect solar radiation from the sun and actively convert that energy to electricity. Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy. The energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their orbits and released, and electric fields in the solar cells pull these free electrons in a directional current, from which metal contacts in the solar cell can generate electricity. The more solar cells in a solar panel and the higher the quality of the solar cells, the more total electrical output the solar panel can produce. The conversion of sunlight to usable electrical energy has been dubbed the Photovoltaic Effect. The photovoltaic effect arises from the properties of the p-n junction diode, as such there are no moving parts in a solar panel.
