Q:Anybody install solar panels themselves?
i do no longer yet i comprehend lots on the venture. e mail for information. a great number of ppl set up them yet just to cover there electric powered warmth/air. It saves them money. i comprehend lots of people who've tiny ones exterior there window to means the lights fixtures in that one room. Its no longer an eye fixed sore the two. i stay in Canada.

Q:Need Solar Panel Guru.....?
I'm inferring that your goal is to save money. You're on the right track with your energy star appliances - saving energy is far better than installing solar panels to cover energy that will be wasted. You may have an opportunity with solar hot water - you would need a large storage tank with 3 people, but that would be the best use of your roof in my opinion. Check with a professional installer, it may make financial sense. Although you could make your own heating panels, it's hard to make a solution as durable as commercial panels. And if freezing is an issue in your area, you would have to drain a homemade system in the winter. With an evacuated tube commercial system, you could keep running right through the winter. In the summer, instead of running those expensive air conditioners, could you just have a cool room in the basement? Anyone who wanted privacy could still go to their regular room and run fans. We have no A/C in our house, and manage, even on those 00+ days. Sounds like awnings or other window coverings might be a big help for you, at least until you can get some deciduous trees in to shade the house in summer. I would advise against making your own solar electric panels. They would not save money over the long term. And check panel prices - they have dropped 50% this year, according to a recent Newsweek article.
Q:What solar panels are the most efficient?
New rollable panels are becoming available that don't have to be permanently attached to a surface and that are more resistant to damage than conventional panels. Right now they are also even less efficient than photo cells at about 0%, but the cost factor may make up the difference. Solar thermal is more efficient than photovoltaic cells. They focus sunlight with mirrors onto a pipe containing a liquid which is then heated to it's boiling point. That turns a turbine to produce power or is harnessed in some other way. The panels are cheap compared to photo cells, don't require perfect manufacture or exotic materials, no expensive maintenance and they are much easier to repair. I don't know of any available to individuals yet but there are at least two companies building generating plants in Nevada with this technology. SunPower is about 22% efficient but even at that rate it will take decades to pay for itself and the panels are unlikely to last that long at anything near optimal efficiency. The cost is just too high at present but solar thermal may provide a good alternative until photovoltaic cells mature, if you can cobble together a system. The final link is about a claimed 80% efficient solar cell that even generates some power at night. It's based on nano-technology, like many promising energy developments in batteries, electrolysis and ethanol production. If it works as advertised it should revolutionize solar tech. Eventually.

Q:How did Obamas funded solar panel plan flop and bunkrupt..where did those billions of dollars go?
Down the drain. That money is gone. Just more wasted money the government writes off and then tries to raise taxes to pay for.
Q:Solar Panel Manufacturing?
At this very moment, most of the people already have an idea on how to create their own solar panels, And creating your own company takes a lot of necessities such as permits ans other stuffs like that,.
Q:solar panel for computer?
Most decent laptops can use 50W of power or more....so you'd actually need a large solar panel with good sunlight. I just looked up how big a 50W solar panel is....it's about 64x64 centimeters...which is very big and expensive! So, solar power may not be the best solution to power, or charge a laptop battery. Maybe there are some solar powered chargers that charge the battery very slowly, but probably not.
Q:how much would it cost to generate MW electricity by solar panels??? and how much land it requires ?
Sorry if I don't have all the specifics you asked for, but Sun Power makes the most efficient solar panels on the market, at close to 20% efficiency. They have made cells with up to 25% efficiency in the lab. That doesn't make it the cheapest but means the most watts per square foot. Thin film panels are cheaper to make but not as efficient. They are about half as efficient as conventional silicon panels. First Solar makes the cheapest per watt right now. So I guess that makes them the actuall cheapest manufacturer. They are able to make them cheap enough to beat out the conventional silicon panels on a per watt basis, despite being less efficient. A company called NanoSolar has the price down close to First Solar's price. These are manufacturers. But they do installations and build utility and commercial scale projects. NanoSolar is less far along in commercialization. They have products, but probably need to wait for the stock market to be more favorable for IPOs, so they can go public and raise the money to move up to scale. The other two are already public.
