What is the easiest and cheapest way to use solar energy in a classroom?

Hi, I’m doing a school project. We are required to design a classroom which exists in a "storage" container, with the idea that this classroom could host 25 learners and be self-sufficient so that it would be able to be used in rural settlements.
What is the easiest and cheapest method of using solar energy? The energy would only need to be used in winter for lighting and maybe a heater/radiator of some sort.
Ideas????

It is possible but very expensive to build a solar system that will make a room the size of a classroom "Self Sufficient" in winter period. May even be practically impossible if located where a lot of cloudy days are experienced.

At least the projects design and cost calculations may open your students eyes to the fact that Solar power is not easy and cheap like the news media likes to make us believe.

I have studied solar power for years. My first guess is you would spend over $100,000 and still not have a system that could support the goal of "Self Sufficient" unless class is willing to spend many days bundled up in freezing temperatures. May be possible in an area like Arizona or the Sahara desert.

What Percent Of Our Total Energy Is Used With Solar?

I cant find the answer to this anywhere. What Percent of our total energy use with solar? Why should Solar energy be used more?

It is less than 5%. It should be used more because we want to reduce our dependence on foreign oil.

way to help hardened criminals back into society?

it seems like all the criminals that just have no remorse, it seems there problem is that they are very one minded. they don’t see how they effect everything.

so, i have come up with a plan to fix this.

we build an island, off in a very deserted part of the oceans, and we separate 5 of them. in distance between each other, to build boats and reach each other. Then on these islands, all 5 are different, and have larger portions of the others resources. but the islands all have the same things. we have houses and solar panels for energy, beds, refrigerators (more like the cold boxes to hold masses of meat). everything that they would need to survive. even chickens and cows, and release animals to the island to keep an wild supply. im talking there will be everything that we eat. vegetables and fruits. but we don’t put any of the houses, furniture, or appliances or solar panels together, they have to do that part, they have no boats to reach the other islands.
but only detailed instructions on how to put everything together. and how to care for the animals. this is a place that is gonna hold like Millions of inmates. they will all have to rely on each others help unless they wish to starve and die. this will teach them that everyone has there purpose. prisons are just giant shitholes. and are more trouble than they are worth. this will move them away from escaping. and help them, and if they survive there sentence. then they are given the option to come back to society or stay there. there would be no women. because reproduction would lead to problems.

so tell me what you think. i know it would cost a lot. but don’t we already spend to much on the prisons already?

Sounds kind of like a penal colony. One of the issues would be that this would be the worst type of people to set up a cooperative society. As long as some are weaker than others, the strong will prey upon the weak. And why should one man tend crops, when he can steal from another who does? I also note that you would put no women on the island. That would mean that even more so than a regular prison, some of the men would get used as women.

I’m also not sure what would stop prisoners from building boats to escape.

And, as you say, cost is an issue. A major issue. I don’t know of any island today that supports that number of people without trade with the outside world. If the solar panels require batteries, where would new batteries come from? For that matter, where would replacement solar panels come from? Surely they would not be manufactured on the islands.

The expense to keep an island like that going would be considerable. We have trouble providing food and housing even for people who are law-abiding but poor.

How should I go about getting a job in the solar/ wind energy industry?

I have no experience in that industry. I am really passionate about it but I don’t know where to start. What should I say to companies when applying? Who should I speak with?

-Hit ALL the "Want Ads" you can get you hands on, & apply, Apply, APPLY !!! :) Good luck !

Capturing Wind Energy versus Solar Energy — Economics Questions — SEE QUESTIONS BELOW?

1) Suppose that you want to erect a 3 Kilowatt [peak energy output in a strong wind] wind turbine.

Assume that the site is located in an area rated in top 20% for annualized wind energy potential [in an inhabited location in the 48 states of the U.S].

1a) Approximately how much will it cost for an off-the-shelf, name-brand wind turbine and suitable tower?
[I am only looking for a range here, I know that the exact cost will depend on vendors, location, other variables, etc.]

1b) How much additional $ for the installation and hookup? Assume that the unit will be hooked up to the grid and unused electrical power will be sold to a local utility company.
[Again, I'm only looking for a range here, I know exact cost will depend on many variables.]

1c) If you amortize the cost over the lifetime of the unit, and include related costs such as maintenance and insurance, and also factor in about half of the power being sold to the grid, what will be the average cost per kilowatt of the electrical power used on-site?
[again, I'm only looking for a range here, I know exact cost will depend on many variables.]

————-

2) Similar questions, only this time for a bank of photovoltaic panels — sufficent to produce about 3 kilowatts maximum in full sunlight. Assume that the site is to be located in an area rated in top 20% for annualized solar energy potential [any inhabitable location in the 48 states of the U.S].

2a) Cost for solar photovoltaic panels, for a 3 KW max capacity? [range]
[Assume they will be installed on a pre-existing rooftop.]

2b) Cost for installation hardware, installation, and hookup? [range]

2c) Amortized net cost per kilowatt? [range]

I have the perfect site for you. Its seems very resourceful & BIG. It has everything you need. Check it out. Good Luck.

when cheap, stored and abundant solar thermal energy?

no chance for dangerous nuclearists.

storage
a thermal pile can be cheaply realized by using the passage of solid and liquid phases.
1 m3 of NaCl(very cheap) can be melted by using about 300 kwh of thermal energy.
1 m3 of silicium needs more than 1000 kwh of thermal energy for melting!
BIG VALUES !!!

cheap and abundant solar energy.
I can realize a big hole in the ground, panel it with aluminium foil so that I can reflect solar beams on a target placed in the ground !
I can close this big hole with glass…for protecting it against dust, rain etc…
Less than 5°000 kmq of Arizona’s surface can be able to produce the double of the actual Usa nuclear energy…

heat of vaporization would be used for heat transfer…: liquid(solar heat absorption) –> vapour –> liquid(heat release)

SO WHEN !?………………………………..

HI,
Can you plz be more specific about your question,i mean what you really want to know about Solar panel technology.
I go through your each step,but could not get your question.
Anyways i know one good site from where you can get details about solar panel installation.

Hope it can help you.
Thanks

New to solar energy systems…?

would this kit:

http://www.spheralsolar.com/products/Solar%252d2%252dGo-10-watt-w%7B47%7D300-Inverter-Portable-Solar-Kit.html

be a decent setup if i upgraded the size of the battery and the size of the solar panel? would it be easy to do? can i hook up more than 1 panel to this? thanks. i just want to run the light that it comes with at night and then have the outlet from the inverter outside if ever needed.
also, if i added more batteries could i get away with this: http://www.freesunpower.com/images/4p_left.gif

the lines that run out would go to the controller so they can charge as well as the inverter.

The set-up is ok; but remember batteries only increase the backup time but also increase the time to recharge and if you want to upgrade the batteries you must need more sunhours if you use the same panel so I recommend to use a system that really solve your needs.

First you must need to calculate your power consuptiom and then the back-up time of power with that data on hand you will choose and efficient system for you

Thanks
