Q:name things someone could use solar panels for or make with solar panels? (use solar energy i mean?): All depends on how many watts you have. I ran a small boom box off a 5w panel before with no problem. The higher the wattage, the more you can run.

Q:Composition and function of solar panels: Used to bond fixed tempered glass and power generation (battery), transparent EVA material directly affect the quality of the component life, exposure to the air in the EVA easily aging yellow, thus affecting the component's light transmittance, thus affecting the components

Q:Our school is in the process of being built, but they have no plans to include any environmental benefits. I was wondering how to get a grant for solar panels (at least) or who I can talk to in order to get a grant.: I do not want to argue over the pay back period for solar panels but from the information I have been gathering, payback could be from 5-5 years, not 40. I guess it depends on the amount of sun that each panel will recieve, so maybe both could be partially correct. Another item to be aware of is that while the cost of your panels and the electricity generated by them will remain stable or decrease significantly for 25 years, the cost of your other energy sources will generally be increasing , perhaps very significantly. Since your school is being built now, it will need a roof. There are photovoltaic shingles for this. Look into it yourself. Do a google search for google green and see what they are doing already. Present this information to your PTA and any other organization who might have influence. This is really a time for your generation to step up and stop listening to nay sayers. Think for yourself, study, research it and broadcast everything you learn to others.

Q:how much do you think it would cost for installation?i heard that solar panels can store electricity and any excess electricity gets sold back to the electric company. how much money can a home owner make from doing this?do you think solar panels are worth it?: Almost sure that you will discover everything related solar power at www.okorder .

Q:If you want to instal solar panels...how often do you have to replace them?: Expect a water heating panel to last about the same as a water heater, 0 to 5 years. Actually, my brother's system is coming up on 5 years, and is not giving trouble yet, so maybe technology has advanced. I have actually never personally known of anyone replacing a solar electric panel due to wear-out. I have heard of occasional replacements due to accidents, including natural disasters like lightning strikes. And one brand of panels had manufacturing defects around the year 2000, but that manufacturer owned up and replaced those free of charge to their customers. A standard warranty on a solar electric panel nowadays is 25 years.

Q:Can solar panels be used to power electric vehicles?: Yes, solar panels can be used to power electric vehicles. Solar panels generate electricity from sunlight, which can be stored in batteries and used to charge the electric vehicle's battery pack. This renewable energy source provides an eco-friendly and sustainable way to power electric vehicles.

Q:How will i construct solar panel?: For powering a something that works on DC, like a gate opener, Elaine is right, and in some cases only ONE bigger cell is sufficient due to battery storage; however if the appliance is 20v AC, then an inverter is needed also. MOST of Elaine's answer is good, but a few corrections are needed: Plywood - use EXTERIOR grade only, and even then it can warp; chipboard or waferboard is preferable as it does NOT warp, BUT is not available most places in 3/8, /2 nominal, (5/32) is usually the thinnest available, and it is heavier than plywood. DO NOT use particle board. Superglue - NO, it dries too fast to be useful, in most cases. Wires - For a single cell OK, but for larger panels the best wire is tabbing wire, (which is flat,) which is available from all commercial solar cell dealers. Be very careful soldering this to the cells, as unless you buy the expensive flexible cells, they are easily damaged; I suggest also getting flux pens with liquid flux. Diode - Necessary, but needs to be large enough to handle voltage and current. Usually 25v and 5-30 amps,, one per panel. Plexiglas - OK, but NOT as long lasting as glass; best glass is the special solar glass which is designed to pass almost all of the proper light frequencies, but IS expensive, and usually needs to be specially ordered since most glass stores do not stock it. Double panes work well with the outer pane glass and the inner plexiglas, (to protect the cell if glass broken,) IF where might get damage, such as 'ground' mounting. AND Frame kits are available for larger panels, but IF you make your own, a good table router is a great advantage. Inverter - IF used for 20v AC appliances you MUST have an inverter capable of handling the load, and the best ones are modified sine, or true sine, wave types, and even the best are less than 50% efficient. Note that they will last longer if NOT used at more than 2/3 capacity.

Q:Can solar panels be installed on a telecommunications tower or antenna?: Yes, solar panels can be installed on a telecommunications tower or antenna. This can help provide a reliable and sustainable source of energy for powering the tower's equipment and reducing its dependence on traditional energy sources.

Q:My solar panel is 24long..It is set at 45deg..the arms are 8quot;long to achieve that angle for winter. I need to get to 7deg for summer..how long will the new arms need to be?..in layman's terms please...thx: 2.20 approximatey (2 /4 -- ish) X = (tan7)(8/tan45)

Q:What is the impact of shading on solar panels' performance?: Shading on solar panels significantly reduces their performance as it obstructs the sunlight required for generating electricity. Even a small amount of shading on a single panel can lead to a significant drop in power output for the entire solar system. Hence, it is crucial to ensure that solar panels are installed in areas with minimal shading to maximize their efficiency and effectiveness.
