Q:Homemade Solar Panel : Hi! guys i want to know what do you think about Homemade Solar Panel?
If you want to make hot water then they are easy to make. Search the web.
Q:Why dont we have a gigantic solar panel system in the warm states,stretching miles across to supply the usa?
This is a great idea, but there are some intrinsic difficulties with the theory: First, the average US household uses 27.4kWh of power per day= aprox. 0,000 kWh per year. Solar panels create kWh/m^2/day. Therefore you would need 27 m^2 (290 ft^2) of solar panels per household. Not only does that use a lot of space, but it would also cost a fortune. We also have to take into account that the government does not want us to become dependent of oil for many reasons. Therefore it is unlikely the government would ever consider paying for it. Lastly, for power grids to stay functional at all times, backup power plants must be kept 'hot', to replace solar power stations as they stop producing. There is an energy cost to keep plants 'hot', which includes (in the case of coal plants) the burning of coal. Unfortunately, if the country is not willing to accept brownouts, the carbon footprint of any large scale solar project will have to accept the 'hot' non-producing power plants carbon emissions as their own. The continued advances in the ability to store electricity will greatly impact the successful implementation of a large scale solar power station being, carbon footprint free. However, it would be possible for every household to have their own solar panels. Since they would need about 290 ft^2 (or 5ft x 5ft), then it does seem reasonable that they could have this much on their roof or land somewhere. Any additional energy you make from the solar panels you can sell back to the power plants and make money. They could then use this extra energy to cover in brown out situations, etc. In order for this to work though, we would all need to be responsible for purchasing and installing our own solar panels. It would be nice if the government would offer greater incentives to do so.
Q:What is the principle of solar panels work?
light - heat - electric conversion method through the use of solar radiation generated by thermal energy, usually by the solar collector will absorb the heat into the refrigerant refrigerant, and then drive the turbine power generation. The previous process is the light-heat conversion process; the latter process is the thermo-electrical conversion process.
Q:What minerals are used in making solar panels?
Not minerals. Elements. Silicon. Found everywhere. Group III elements for doping. Group V elements for doping.
Q:How do you set up 30w solar panel?
With a 30 watt panel, producing about 2 amps, your not going to have much power from that. A 22 AH battery will give you 2 AH of usage. A battery should never be drained below 50%. What this works out to be is simply Amp draw for 2 hours. Which equals to 2V light bulb that draws amp for 2 hours. Not much. Now to replace that usage with your 30 watt panel, provided the panel is clean and in max sunlight, it will take 6 hours. If you attach an inverter to your system for 5 Volt Usage then the DC voltage drawn from the battery is very high. Example: Say you use a 5 Volt component that requires 50 Watts per hour to operate. The inverter will draw 5 Amps out of the Battery every hour to operate that component. That gives you and /2 of use before the battery is down to 50%.. Maybe that will be enough to charge up a standard Laptop battery. I have 2 30 Watt panels that produce 5 Amps, 4 6V batteries that have 480 AH and a 25 Amp Controller with a booster that increase the amp output to 20 Amps per hour. I live full time in an RV and raise the panels to get max output when I am parked. This system provides me with all the 5V throught the 500 Watt inverter that I need. Good luck on you system.
Q:What is so great about solar panels ?
Almost sure that you must pick up everything that have to do with solar energy at www.okorder.com.
Q:Have a 40watt 20volt solar panel, how many watt of inverter do I need?
500 Watt Solar Panel
Q:Are Solar Panels worth it in Southern California?
I'm confident that you must pick up everything concerning solar power at www.okorder.com.
Q:Anybody install solar panels themselves?
If you're in San Francisco, then the price of labor is going to be high. It's still legal to install your own, but you'll need to pull a permit, and get an inspection. If you hunt around on the PGE website, they'll guide you as to requirements. Aside from a standing-seam metal roof, the easiest install would be over asphalt shingle. As with any roof penetration, flashing and sealing the holes is critical.
Q:When you get solar panels do you connect them to the grid?
You okorder.com/ as they provide very accurate free solar quotes and break down all the incentives you will be eligible to receive, your estimated annual savings, your payback period, projected IRR, and a cash flow analysis. They taught me everything I know about solar, and I must say they're a great starting point if you're curious about what solar energy is all about.
