Q:Can solar panels be installed on universities or educational campuses?: Yes, solar panels can certainly be installed on universities or educational campuses. In fact, many educational institutions worldwide have already embraced solar power as a sustainable and renewable energy source. Installing solar panels on campuses not only helps reduce carbon emissions and combat climate change but also serves as a great educational tool for students to learn about clean energy and sustainability. Additionally, universities can benefit from cost savings on electricity bills and even generate surplus energy that can be fed back into the grid.

Q:Do solar panels require a specific type of inverter for converting DC to AC power?: Yes, solar panels do require a specific type of inverter known as a solar inverter for converting DC (direct current) power generated by the panels into AC (alternating current) power that can be used in homes and businesses.

Q:I've been reading up on Solar panels because I think in the long run this would be beneficial in the long run. My Dad had looked into it before passing and had said it was too expensive. How much does it range for getting them placed on the roof and how exactly does that work? I think I remember being told that PGE has incentives and could possibly even end up paying you for having it? What does having panels cover? I know electricity but does it also heat things up? Sorry I'm kinda dee dee dee on this lol. Any and all information would be greatly appreciated. If anyone has solar panels can I get your experiences with them? Thanks!!: The solar panels that we all simply would think are the greatest thing ever are very, very expensive and require strip mining of huge areas of land to make. For several million dollars you can buy what usually is mounted as power source for space satellites upon your roof. This 2'x2' panel and a barrage of battery storage takes care of all the electrical needs you could ever have at home. But this profoundly environmentally destructive technology is not what you had in mind, I'm sure, but is what has been around for quite some time now. It's been a challenge to make solar panels without using complex chains of excited rare metallurgies, but we seem to be getting better and better at it--but I trust others should help you with the practical, now that you know the best panels are not best for us at home.

Q:What direction do solar panels usually point? North? East? South? West?: The general answer is toward the equator, so south when the array is north of the Tropic of Cancer, and north when south of the Tropic of Capricorn. In the equatorial zone, one would often still point towards the equator, but other factors such as wanting the panels to efficiently drain rain and dew come into play. But wait, not so fast. Financial considerations dominate in some areas. When afternoon electricity costs more than morning electricity, it may pay to have panels oriented southwest in the northern hemisphere. Where electricity costs the same all day long, it may pay to orient the panels southeast, to harvest more in the morning, when temperatures are cooler, and the panels are more efficient. For solar hot water, SW is usually optimal in the northern hemisphere, because of higher ambient temperatures, and also the usage pattern of most people using the hot water when they get home in the evening. A local installer that has been around for several years will know what orientation is optimal for your area.

Q:I'm from Toledo, OH about 2 miles from the MI line. We are a foster family and have adopted 5 children. We just moved into a 5400+sq 2 story home. We have (3) 2.5-3 ton AC units to cool this huge house. We got the house cheap...$75k couldn't pass it up! Anyway...I was wondering how many solar panels it would take and of what wattage to power these Central Air Units and maybe the rest of the house. We have 3 people in our home......9 of which are children who leave the lights on and run hot water to beat the band. We have all brand new energy star appliances and front loader washer and dryer. Gas Range and Gas hot water tank. Was thinking of using metal window frames and buying solar cells and making my own panels. Just don't know how much to buy. We face south with no trees. Constant Sun. thanks for your help. An e-mail address to bounce questions off of would be helpful if you experienced. tx.: With your load, the largest system on the page I reference above would not power your entire house, if all the AC units are running. However, how often does that really happen? You need to look at your utility bill and find your actual amoutn of KW hours of electricity used in a year and you hav enot told us that. The base price of top system quoted here without incentives is over $70,000. As you can see, the lions share of incentives is the utility company followed by federal. I have no idea if your local utility company offers incentives or not. You would have to resolve that with them. However, the federal incentives are still there even if your state and local utility has none. However, the price to you goes way up without all of these incentives. And your idea of using windows to mount solar cells is totally impractical. Yes, I know there are web sites that advertize just that, but it is total BS. The first word of advice to anyone looking to do this sort of thing is to FIRST have a complete energy audit done and then do whatever they say to conserve as much energy as possible, thereby reducing your need for solar power. Only then should you look at using solar to cover part of your load. We are a foster family and have adopted 5 children< WOW! I would like to thank you for what you do.

Q:Can solar panels be installed on flat roofs?: Yes, solar panels can be installed on flat roofs. In fact, flat roofs are one of the common types of roofs where solar panels are installed. However, proper installation techniques and mounting systems are required to ensure optimal efficiency and safety.

Q:Since plants have been populating this earth for the past 475 million years I think they have evolved to gain the most sun with their greenery. If scientists used heat sensors to find the hot spots of trees and trim all of the leaves that don't quot;providefor the plant, then maybe that trimmed tree could be used to become a solar quot;panelquot;. I believe that each individual leaf could be replaced by a small solar panel and the wood of the tree would be wiring that would root all of the solar panels to a generator.: From the vantage point of a scientist and an engineer, you have a whole host of problems to overcome. The mass of solar cells cannot be supported by most leaves much less allow the leaves to turn toward the sun as they naturally do. The wood and other structures of a tree are terrible conductors and wouldn't serve as efficient power transmitters. There are issues of damaging the health of the tree by interrupting the process of photosynthesis in favor of solar energy collection, and many other issues. However, I can tell you that solar power does use several principals that you have observed in trees. For example, solar collectors are almost always oriented to face toward the sun. Many adjust with the time of day and seasons to be optimally oriented to collect the sun's rays. Much like leaves in many plants are not static but change position to optimize their angle to the sun. Also, many solar cells are now designed with a membrane structure which offer several advantages. So you see many of your observations have found their way into practical application in solar power production.

Q:Can solar panels be installed on a gas station or fueling facility?: Yes, solar panels can be installed on a gas station or fueling facility. In fact, many gas stations and fueling facilities have started installing solar panels as a means to reduce their carbon footprint and decrease their reliance on traditional energy sources. Solar panels can provide renewable energy to power the facility's operations, including lighting, pumps, and other electrical systems. Additionally, solar installations can help gas stations and fueling facilities save on electricity costs in the long run.

Q:If a solar panel is a .5kW system, what length of time is it putting out that much power? Every hour?: Power = work done/time taken In other words, Watts=Joules/second. In this respect, power is a little like speed (m/s). Your question is looking at a car with a 50mph top speed, and asking how long is it going that fast? The solar panel will produce .5KW for as long as you require it. Enough to boil a kettle, run a modest electric heater etc,

Q:Can solar panels be installed on a government building or facility?: Yes, solar panels can be installed on a government building or facility. In fact, many governments around the world are actively promoting the use of renewable energy sources, including solar power, to reduce their carbon footprint and promote sustainability. Installing solar panels on government buildings not only helps in generating clean and renewable energy but also sets an example for the community and encourages others to adopt green energy practices.
