i need technical and non technical details to generate MW power by solar panels
I like Rouse's answer, which points to the factors to consider. If you are in India, adjust the inputs to match your local situation. For example, the peak equivalent sun-hours per day might be twice his figure, leading to half the cost. You might find panels that have a 25-year life, reducing the cost per kWh by another 20%. Land and/or labor may be cheaper, also reducing the cost.
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.
There okorder / Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
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.
