A: Yes, we can do that.

Q: The Physics club in our school is trying to convince the Board of Ed to install solar panels in our school, and i was just wondering if anyone with some experience or real expertise in solar energy. I need some points about their usefulness some real pros and cons on maintenance, etc. Anything will help. Personally i would be perfectly for the idea, but i heard that the overall cost of installing them is much higher than the cost of the energy saved and government subsidies, but ive only heard about this.: Cuts Costs over time

Q: solar panels!!they are fantastic! cause they are the new way of quot;chargingyour home, without killing the earth!would you install them, or not? and make sure you say WHY: I believe the best economy comes out when a completely green house is built. Solar panels are expensive, and I'll rather use some of the investments to build different back-up systems, instead of bying solar panels for it all. If I build another house, my fancy stuff would be the green stuff. The house will have a water radiator heating system and a heat pump to circulate warm or cold air in the house. Heat pump also used to heat water for heating system. I'll use solar panels to make enough electric power . charging a deep cycle battery pack for back up power, 2. to power heat pump, fridges., freezers, and water pumps, when I'm not home at the house. When I'm home I'll run a bio-fueled(bio-waste and pellets or firewood) powered steam engine with a 0KW 0-220V generator when I need electric stove and oven, dishwasher and laundry appliances. I'll use a wood stove, BBQ and oven on the porch for summer cooking. I'll use excessive heat from steam engine for heating water tank. I'll also have an bio-fueled (waste and pellets or firewood) water heater for winter heating back-up. Of course I'll make sure I'm connected to the electric grid, so I can get credit from power company for the excessive electricity that will occasionally come out from solar panels. Steam engine can be replaced by diesel powered 0KW generator, if it's possible to fuel it with veg-oil home made diesel fuel. Depends whats most accessible at my living site.

Q: How do solar panels affect the roof's lifespan?: Solar panels can actually help extend the lifespan of a roof. They act as a protective layer, shielding the roof from harmful elements such as UV rays, rain, and snow. Additionally, solar panels can reduce the temperature of the roof, which can help prevent heat-related damage.

Q: Can solar panels be used for powering outdoor signage?: Yes, solar panels can be used to power outdoor signage. Solar panels harness sunlight and convert it into electricity, making them a sustainable and eco-friendly option for various applications, including outdoor signage.

Q: I have a panel that quot;deep breatheproduces at 4% efficiency, what can it power, It's about 4ft by 2ft: Area is 4' * 2' * (0.3048m/ft)^2 = 0.743m^2. Incoming solar (assuming optimally oriented panel) averages about kW/m^2, so 743W max gross. 4% efficiency yields 300W. Most panels are about 0% - 5% efficient, which is about W. In either case, figure about /2 the theoretical efficiency for about 2 hrs per day. so, you can run something from 50 to 50W about 2hrs per day. Too small for any appliance except maybe a laptop or light bulb. Panels typically make about 2V, not enough to run household stuff anyway. Normally panels are used to charge batteries, then an inverter takes power from the battery to run your appliances. Good luck!

Q: How much solar energy does a 2m by a 3m solar panel convert to energy on a sunny day? Assume that the solar cells are 30% efficient.I'm not looking for the answer so much as I need an explanation o how to solve this type of problem... Thanks!!: You have the area of the solar panel. You know their efficiency. What you need to know now is the energy (per area) delivered by the sun. The energy delivered by the sun can be found on the internet. Earth ,43 – ,32 W/m? (wikipedia) That is offcourse for your solar panels perpendicular to the ray's of the sun. If they are under an angle you should see what the area of the projecton of your solar panel is on a plane perpendicular to the ray's of the sun. So know you have the intensity W/m? and an area (or effective area). Here you go the energy deliverd by the sun. And 30% of it is what you get out of your panels.

Q: I want to buy a solar panel kit to run my central AC unit. it is a 3 ton unit. Can I do this? The electric rates in the Chicago area are skyrocketing and I can't keep paying 350 dollar electric bills during the spring and summer months: It sounds like saving money is your chief goal. If your house is not already super-insulated, that should be the first target. Super-insulation, radiant barriers, double-pane windows, white roof, weatherstripping, attic fan. Number two would be conservation. Can you turn the A/C up to 80? I visited a place in Wyoming when it was 0 outside, and 80 felt very pleasant. Third, efficiency. Have you considered a ground-sourced heat pump? Deep down below your house the water table may be colder than 40 degrees F, and can provide good cooling. After all that, you can look into solar electric, which may or may not be a good deal in your area. The type of solar electric that is most cost efficient is the kind that connects right to the house wiring and works alongside the normal electric company. You can talk with a local installer and get a free financial analysis. Then you can look at it and see if the installer is on the level, or trying to play accounting tricks with unreasonable assumptions. Solar makes sense in most parts of California, but Illinois is not known as a big solar area. The kits you have have seen were probably for standalone solar, generally an expensive proposition for the amount of power you get. Put another way, either it will be low power, or it will be very expensive.

Q: The first solar panel that creates energy from UV rays... who created it: No solar panel creates energy. The earliest solar panel of any form was probably the parabolic mirror as used, for example, to light the Olympic torch. That goes back to ancient times.

Q: Can solar panels be installed on a church or place of worship?: Yes, solar panels can be installed on a church or place of worship. Many religious organizations have taken steps to embrace renewable energy and reduce their carbon footprint by installing solar panels on their rooftops or open spaces. Installing solar panels not only helps to generate clean and sustainable electricity but also serves as a visible symbol of the organization's commitment to environmental stewardship.

Q: Can solar panels be installed on any type of roof?: Solar panels can be installed on almost any type of roof, including asphalt shingle, metal, tile, and flat roofs. However, the feasibility and ease of installation may vary depending on the roof's condition, angle, and orientation towards the sun.
