Q: Can solar panels be installed on a concert venue or entertainment facility?
Yes, solar panels can be installed on a concert venue or entertainment facility. In fact, many venues are increasingly adopting solar energy as a sustainable and cost-effective solution. Solar panels can be installed on rooftops, parking lots, or open spaces around the venue to generate clean and renewable electricity. This not only helps to reduce the environmental impact but also saves on energy costs in the long run.
Q: I'm building a solar panel for the first time and have the tabbed solar cells. I put together 4 strings of 9 cells. And the cells are each 0.55V, 3.6A.Because I'm going to be using the panel indoors and leaning it up against a window pane, I put them in a 24x36 inch poster-size frame. The frame has a plexiglass cover and a thick cardboard backing. My question to you is this. Will the cardboard backing up against the metal underside (positive side) of the solar cells be ok? I don't know if it may catch fire or if holes may burn through when there's full sun.My guess here is it should be ok. But maybe I'm wrong. If I am wrong, or if something should be put in between, please let me know what I should use.Thanks everyone!

Q: How Much energy does Solar Panel Produce,and How long can Solar Panels go without maintenance.
There really isn't any maintenance you need to preform...all you really have to do is clean the surface once in a while. However cleaning the surface is not crucial. A rough rating for a panel is about watt for every 9-2 square inches.
Q: The ancients used skylights for light in lieu of electricity. Light was used for drying, even cooking foods and drying clothes. Solar clocks/sun dials were once popular but now we have battery operated clocks. Where have we tapped into any of these resources since the outdated solar clothes drier nicknamed the 'clothes line'?
Have you seen the industrial solar power tower they built in Spain? It has a very large collection of mirrors which direct sunlight toward a single point at the top of a large tower. There a boiler turbine generates a lot of electricity! It is a genius concept that could easily be installed in North American deserts.
Q: Can solar panels be used in areas with high levels of wind-blown debris?
Yes, solar panels can be used in areas with high levels of wind-blown debris. However, it is important to choose durable and robust solar panels designed to withstand such conditions. Regular cleaning and maintenance might be required to ensure optimal performance and longevity in these environments.
Q: I want to be more self sufficient and get solar panels for electricity in a small house any tips will help. i need to know how many watts is enough and ect.
Unless you're very rich, you won't be able to afford solar panels that can meet the average demand of a home. In the US, the average demand for a home is 920 kwh per month, which amounts to 3,833 Watt panels if you assume 8 hours of usable sunshine and don't take into account your location. At current installation rates that's easily a $9,65 project. If you assume a 25 year useful life, it amounts to a return of 3.3% per annum at 0 cents a kwh not counting the costs of repair, insurance, the inverter, any fees to the utility for net metering if any etc. You would be better off putting $9,65 into a mutual fund until better technology or government incentives came along, in some areas, the government subsidies can make it worth your while. Also, keep in mind that in many areas, the net metering arrangements only deducts the power you've generated from your bill so you would want to size the array to meet your base usage in order to get the most from your investments. So meeting your actual needs would result in a loss on the return as there will be months where your usage is less than your average. In theory, if you put $7,208.69 into a mutual fund expected to return 4.4% per annum then you could withdraw enough to pay each month's power bill for 25 years at $0.0 a kwh and therefore be self sufficient through financial means. You would get more mileage focusing on heating and hot water as heating and hot water is 75% of a home's energy use and can be addressed with lower cost technologies like passive solar and solar thermal panels. You have to put it into perspective, it's an investment and you want a return that's competitive with your investment opportunities.
Q: What is the most efficient solar panel, how many would we need to power the United States, and how much land would it take?
Annual power consumption in the US is approximately .2*0^5 Watt-hours. The average solar panel can generate 80W continuously. We can break up the calculation into parts: .2*0^5 Watt-hours per year 925 hours per year .3*0^ continuous watts 80W per panel 64383566 panels 000 sq. inches average solar panel area 650 million square miles (!!!) To give you a better idea, the total surfacre area of the United States of America is 3 million square miles. The surface of the earth is 96 million square miles. Not even 3 planets full of solar panels would be enough. Maybe it is easier for people to start using electricity more responsibly?
Q: Can solar panels be installed on a high-rise building?
Yes, solar panels can be installed on a high-rise building. In fact, high-rise buildings offer great potential for solar panel installations due to their large surface area and access to sunlight. However, it is important to consider factors like structural integrity, shading, and local regulations while designing and installing solar panels on high-rise buildings.
Q: Simplfy it so i can understand pls and put it in stages such as . sun hits solar panel plsHow many different types of solar panels are there?
Solar panels is built of the solar cells in it..these cells are typically made of paper thick Silicon or Germanium metal (called semiconductors).When light falls on these solar cells the energy recieved from the light (photons)is used to emit electrons due to the nature of semiconductor material. These electrons being of negative charge are attracted by opposite positive charges or there is current flow from cathode to anode on these cells.This small electric charge generated is used to store in the battery connected...more the number of solar cells more the electricity generated .
Q: What is the most powerful solar panel made?
Yeah lead acid is the desirable yet once you've a higher image voltaic setup like 200watts or extra you extremely want a cost controller in addition they favor to be vented because even as they're charged the produce hydrogen that once concentrated burns and is no longer good to respire in. the worst section about lithium ion is they imeadiatly commence to decompose once they're used so that they in straight forward words very last 2-4 years the position lead acid can very last over 2 years if good maintained.
