Q:My family and I are looking into solar panels for our home. But I'm unsure how it would be priced. This month our home used ,623 kwh. The solar panel company said we should expect $6-$9 per watt used. What would that put as at?
It is easier if you will going to visit a number of solar panel company just to be sure that you have the right values. Some of them will give you a free solar panels quote. Compare and select options that will best work for your home and budget.
Q:Can solar panels be used for powering a research facility or laboratory?
Yes, solar panels can be used to power a research facility or laboratory. Solar panels convert sunlight into electricity, providing a sustainable and renewable source of energy. By harnessing the power of the sun, solar panels can generate enough electricity to meet the energy demands of various equipment and appliances used in research facilities and laboratories. Additionally, solar panels can be combined with energy storage systems to ensure continuous power supply even when sunlight is not available.
Q:Can solar panels be installed on any type of roof?
Solar panels can be installed on most types of roofs, including flat, sloped, and angular roofs. However, some factors like the roof's orientation, shading, and structural integrity may affect the efficiency and feasibility of installation.
Q:I'm looking to mount a solar panel to the top of my 2003 Pontiac Montana and was wondering how i could do it without any screws? Magnets maybe?

Q:Interested in buying solar panels to save on electric bill.Any government help plans?
I live in Ohio so I'm not sure if this is nationwide, but in Ohio there are grants you can apply for if you're investing in alternative energy for your house. I would look into those grants if they're available in your area.
Q:What is the difference between Photovoltaic Panels and Solar Panels?
Both of them are different types of solar panel. EDIT: Misspelling on Jeff's answer below! I think he means 'silicon,' not 'silicone!' Solar cells are typically grown on a glass substrate or put onto glass. Silicon is currently the most common material, followed by CdTe or cadmium telluride. Other materials like CIGS (Copper Indium Gallium (di)Selenide) are breaking into the market. Some people have great hopes for organic or 'dye' solar cells.
Q:i need to make a mini-solar car which shouldn't cost much. it's for my science project. for now, i just found out how to make a solar panel using copper oxide, but it does not generate enough power to power up the engine of the toy car [ the small engine they used in the toys, like from TAMIA]
There are several types of solar panels. If you mean photovoltaic panels for generating electricity, that is a really advanced project that few amateurs are equipped to do. In the long run, it will be a lot cheaper and easier to buy factory made PV panels. You can try building one by sandwiching an array of photovoltaic cells between a sheet of glass or plexiglass and a sheet of aluminum. Remember that this assembly must be able to withstand great heat, and it must be sealed to make absolutely sure it does not leak.
Q:Can solar panels be used to power a greenhouse?
Yes, solar panels can be used to power a greenhouse. Solar panels are a sustainable and efficient energy source that can generate electricity to operate various greenhouse systems, such as lighting, heating, ventilation, and irrigation. By harnessing the sun's energy, solar panels provide a clean and renewable power supply, reducing greenhouse gas emissions and minimizing reliance on conventional energy sources.
Q:China is building solar panels and have been for years. That is the most abundant energy in the world. My nieghbor has two panels on his roof and he actually sells energy back to the electric company. These panels cost about $30,000. each, because we don't produce them here on that level.If we did, that price would drop drastically. Other alternatives are also available. Drilling for oil will no change anything. Once you give the oil companie the go ahead, the will focus on that and the alternatives won't be developed any farther. We will be right back here in about 0 years. The price will not go down anyway. So why not switch half of our fuel to alternatives?
I know for a fact that -China has a lot of Nuclear Bombs pointing at the US--- paid for by Wal-Mart
Q:Hey guys :)Well I'm in the middle of doing my PSHCE coursework on sustainable energy, focusing on solar panels. I just wanted to ask you what your opinions are of them? Are they really worth it? Are they sustainable? Will they reduce our energy bills? Those sort of questions :)If you are interested in installing solar panels, please mention that, as it would be great! There's lots of information about them on this site ----
Bing solar power in Germany. Solar power has an option of assisting in removing some of the burden during daylight, from power generation plants. Anything is a help. Plus they will continue to do it forever (at least a lifetime). But they are not the total answer. Like wind, limited to certain areas. Wave generation is another solution, but still limited to coastal areas. The current design of most supply grids does not allow transportation of power long distances. You want a real eye opener, Bing transportation line looses power grid and see how much energy is wasted, and the amount of carbon put into the air for these losses.
