- Q:Can solar panels be used in space?
- Yes, solar panels can be used in space. In fact, they are commonly used to power satellites and spacecraft as they can efficiently convert sunlight into electricity even in the absence of an atmosphere.
- 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:Are the solar panels on the roof just a gimik to get all the tree huggers to buy it, or are they actually a good, efficent design?
- Create okorder /
- Q:Well my dad has been into Solar panels for quite a while, his birthday is coming up and i want to get him a small minature one, so he can toy around with it and be able to use it as expirience for when he gets a bigger one. my dad has been doing ALOT of studying, and i've been looking online but idk what kinda kits to get so should i get a 0w kit, 5w kit, or 20w kit? which one would be best to fool around with and play with? thanks
- The okorder /... All the other sites you google/yahoo for will be advertisements. I think the author of this one was a engineering student. Hope this helps!
- Q:Can solar panels be installed on a retirement home or assisted living facility?
- Yes, solar panels can be installed on a retirement home or assisted living facility. In fact, many such facilities are embracing solar energy as a sustainable and cost-effective solution. Installing solar panels can help reduce energy costs, decrease reliance on the grid, and contribute to a greener environment, all while providing clean energy for the residents.
- Q:solar panel capacity, how do it work
- Well Capacity is totally depends upon quantity of panels and size of panels. You can install panels according to your requirements.
- Q:I want to replace my electricity with solar and wind. I live just right outside the city, the roof about 000 square feet. How many windmills/solar panels would it take to get me off the power grid?
- If you are in the desert and near the equator you will need fewer panels than if you live in a rain forest or Alaska. If you live in a wind tunnel with consistent strong wind, you will have better results than if you live where there often is a lull in the wind and changes of direction of the wind. If you already pump your water by hand, generate your own electricity by cycling using your legs, and go to bed whenever it gets dark out, you might make it. But if you tend to cook and launder on the grid, run a refrigerator, perhaps heat your house or air condition it, own various gadgets you plug into outlets to use, like lamps, puters, toaster, shaver, blender, dishwasher etc, you may not be able to get off the grid.
- Q:Ok so I am planning on buying a solar panel. I am doing it to possibly sell the energy that it stores. It is a 20 watt panel so I am just wondering if every week or month if I sold that energy that it stored would make me a good profit. I am not hoping for thousands of dollars a month..just like 00? The solar panel cost me $,00 so if so, how long do you think it would take to make good profit. Also, how much would I make every week or month?
- I will give you the tools to answer your own question. Here is the solar resource map: rredc.nrel /solar/old_data/nsr... Use it to look up the hours of peak equivalent sunlight per day in your area. For example, let's say it's 5 hours / day. Then per year you get 365 x 5 = 825 hours of sun Your panel is 20 watts, or 0.2 kW So the energy produced per year is 825 x .2 = 383 kWh You'll have to use the proper numbers for your own area, of course. Anyway, you can take that 383 kWh and determine how much it would cost at local electric rates. Never know, on some islands, it's $.00 per kWh. Check with your local electric company for rates.
- Q:Can solar panels be used in areas with high winds?
- Yes, solar panels can be used in areas with high winds. However, it is important to ensure that the solar panels are properly installed and securely mounted to withstand the high wind conditions. Reinforced mounts and sturdy frames are typically used to anchor the panels securely in place. Additionally, frequent inspections and maintenance might be required to ensure the panels remain intact and functional in such environments.
- Q:we are doing a fundraiser to have students pledge to make donations for a solar panel instalation on one of the school buildings. I am looking for a slogan for the campain.
- nasa solar panels seem to be better than silica / silicone (i forgot the exact chemical) they make them with ink and aluminum then case them in glass, they are supposed to last like 30 years or something. good stuff. anyway a SLOGAN: solar pannels save money, and over the long run allow the school to save tht momney or use it somewhere else in the school, ie better food, better seats, better computers, whtever. maybe you can relate the campain slogan to what the savings will be used for. maybe a new scince program thats funded solely on the savings of the panels. but ok a slogan: IT'S OBSCEEEENCE, ROTFL... GIVE SOME DOLLAR$$ AND GO GREEEEEN!!!!!! eh, i know not so hot, gimme a minuet. lol LET'S MAKE THIS PANEL HAP'N CAP'N... MIB! LMAO THE SUN, FREE FUN, COME ON AT LEAST GIVE ONE (place pic of dollar bill below the ONE) good luck.
