Q:Can solar panels be installed on beach resorts?: Yes, solar panels can be installed on beach resorts. In fact, beach resorts are an ideal location for solar panel installations due to their large open spaces, ample sunlight, and potential for reduced electricity costs. Installing solar panels on beach resorts can help them become more sustainable, reduce their carbon footprint, and contribute towards a cleaner and greener environment.

Q:Can solar panels be installed on multi-story buildings?: Yes, solar panels can be installed on multi-story buildings. In fact, multi-story buildings often provide ample space on rooftops for solar panel installation.

Q:Can anyone give me a simple but informative explanation on how solar panels produce electricity/power? Thank you!: solar panel absorb sunshine , and it will produce electric charger, the charger move to one direction, it wil produce electric current, so it produce electricity. the electricity can through cable move to solar battery to store or to country power grid to provide electricity for people using.

Q:how much do solar panels cost?: The okorder

Q:Can solar panels be used in areas with high humidity?: Yes, solar panels can be used in areas with high humidity. However, high humidity can potentially reduce their overall efficiency due to increased moisture in the air, which may affect the performance of the panels. It is important to ensure proper maintenance and cleaning of the panels to prevent any buildup of dirt or moisture, which can further affect their performance in humid conditions.

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.: You have to approach it as an investment. Ignoring the cost of an inverter for net metering, if we consider a 500 W panel installed for $0 a watt which is $5,000 and consider an average of 8 hours of usable sunlight per day, and at a rate of $0.0 per kWh (schools probably get $0.03 per kWh) then the panel would be saving $2.7 per month in electricity. Considering that the panel has an expected lifespan of 20 years, that would give you an internal rate of return such that the monthly rate satisfies the equation: $5,000 = $2.7 * ( ( - / R^24 ) / ( - / R ) - ) By binary method we get R = 0.99588342. Taking this to the 2th power to annualize it we get Ra = 0.9570 which means that we are getting an annual return of -4.83% per annum so investing in the solar panel is the same as making an investment at an interest rate of -4.83% per year. True interest rates are low and you only get about .3% per annum by putting money in a CD but that still beats investing in solar panels which gives you a negative return on your money. Solar panels need to get a lot better before they are a good investment.

Q:How do solar panels impact the roofing material's lifespan?: Solar panels can actually extend the lifespan of roofing materials. They act as a protective shield, shielding the roof from harsh weather conditions such as rain, hail, and UV radiation. This helps to prevent damage and degradation, ultimately increasing the longevity of the roofing material.

Q:I have a playstation PSP charger that is 5v 2A, so it takes 0 watts.I have several small solar panels that put out watt a piece and are 4 volts, 250mAhow can I get my 0 watts to be 5v 2A instead of 4v 250mA? the voltages have to match up right?also, what's a 3-T regulator that controls voltage?: 3-T is just one type of many devices designed to control voltage so you get the amount you desire with as little static as possible. Without you having an degree in engineering, I can't explain it to you any better. You will also need to produce true sine wave energy or you will burn out your PSP with the correct volts and amps. You need one to produce only 5 volts 2amps. Anything different will burn out yur PSP. Your problem is simple math. Watts = volts multiplied by amps. Amps = Watts divided by volts. So if your solar panels can produce /4 amp ( 250 mA) each, then you connect one to the other in a series until you get enough connected to make 2A. ( 8 panels { /4mA x 8 = 2A}) You now have a panel with 32Volts, 2Amps, 64 Watts. This is where the T-3 regulator comes in. If you buy one for 5 volts, it will allow only 5 volts 2 amps, to go to your PSP.

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.
