Q:what do solar panels do?
The cost of electricity is increasing at a rate of 5 to 0 percent every year with no end in sight. A solar panel system captures the (free!) sun and turns it into usable electricity for your home.
Q:how much would it cost to generate MW electricity by solar panels??? and how much land it requires ?
First off, you should consider cost per kilowatt-hour (kWh) since kWh is energy whereas MW is power, and kWh is a common unit of energy used by power utilities. But first you would need to design the power capacity required, which as you state, is assumed to be MW. Average system costs = $95 per square foot Average solar panel output = 0.6 watts per square foot Average solar energy system costs = $8.95 per watt Form this information, the capital cost of installing MW = $8.95 /W * 0^6 W/MW = $9 million. The lifetime of a typical solar power system is probably about 20 years. Assuming a true MW peak output of the solar panel it would be anticipated that a daily average energy production would be peak output over about 3 hours per day, or 3 MWh of energy per day. Total production over a 20 year system life would be 3 MWh * 365 days/yr * 20 yr = 22 x 0^3 MWh So in terms of costs of capitalization of the system, the cost of Energy (/kWh) = $8.95 million / 22 x 0^3 MWh = $0.40 / kWh (approximately) This cost does not include maintenance, however, given the simplicity of these systems; other than periodic equipment replacement, which is covered by specifying a 20 year complete system replacement; other maintenance cost should be relatively low. The required surface area of solar panel = 0^6 W / 0.6 W/ft^2 = 94,340 ft^2 or a little over 2 acres of panel surface area. To be able to properly access and maintain the solar array, the minimum area required would likely be 5 to 0 acres.
Q:Can I made my own solar panel?
Have okorder.com . This could definitely help you!
Q:Solar panel trouble?
To test a solar panel, connect a voltmeter, and turn on and off a light. If the voltage increases when the light above the panel is on, it is working. The solar panel does convert solar (light) energy into usable (electrical) energy. No extra conversion is necessary to make eletricity. You might, however, want to convert .5 VDC or 2 VDC output of solar panel(s) - or the batteries they charge - to 20 VAC with an inverter though. If a capacitor is broken, it will look like an electrical short circuit all the time.
Q:how often do you have to replace solar panels?
My panels came with a 25 year warranty. I will have to replace the converter ($000) at some point, 2-5 year mark. I should breakeven within 6 years thanks to great rebates in my area. I've heard that they lose some efficiency over time, but I know people who have had panels for over 0 years and if they have drop off some, it isn't noticable.
Q:Solarcity free solar panels?
What that means is free, considering the cost of electricity saved, i.e., no additional out-of-pocket costs. It could still be a good deal. For example, your bill is now $200 a month. Maybe the solar drops your bill to $40 a month, and you pay $50 a month to SolarCity for the duration of the lease. One thing to remember, though is that only works if your bill drops to $50 a month or less. If the panels don't produce enough, you may end up paying a $60 electric bill, and still $50 to Solar City, for the duration of the lease. They will also count on getting your federal tax credit, so I don't know how that works into the price. Also, they must make money as a leaseholder or financer, so it shouldn't be as good a deal as simply installing panels and paying for the whole thing up front. We installed solar electric in 2006, and it's still working great. If I had to do it over again, I think I'd get solar hot water first, though.
Q:Do they make solar panels like this?
Homemade okorder.com
Q:How do you store energy using a solar panel?
Solar panel is not a energy storing device, rather it converts light energy to electrical energy and this energy either can directly used to run instruments or can be fed to battery for storing. The working of the solar panel is like the inverse action of a LED, i.e. a LED converts electrical energy in to light where as a solar panel converts light energy in to electrical energy, basically it is a P-N junction diode.
Q:What are the benefits of solar panel heating?
Firstly,it is environment friendly,solar energy can replace electricity,so it reduce the carbon emission.Secondly,solar energy is cost effective,you will not pay any bill for electricity any more.
Q:selling solar panels online - a good idea?
Presently the technology is not there using green energy. Green energy is popular, but not as effecient as they claim. There is no product today whether it is electric cars, windmills, solar panels that have a lucrative payback. They all have their drawbacks. Your thinking is good, but the market and the techology just isn't there yet. If it were, you would see solar panels on every house. You already have the competition as you noted, and they aren't prospering... Good luck.
