How much do solar energy panels cost?
Buying solar panels can be very expensive, especially for installation. If your average daily usage is 6.6 kilowatt per hour, then you would need a 2 kilowatt system that could generate ten kilowatts per hour in a day. This system could cost between $10,000 to $20,000. Of course, the higher wattage, the higher the cost. There are some alternatives to spending thousands of dollars on solar panels. 1) Buy several solar panel kits and link them together yourself. 2) Combine solar with wind power to decrease the number of panels you will need. 3) Build your own solar panels for around $200 each. If you are handy with some basic soldering, then you can make your own solar panels.
Cost of Solar Energy?
We am looking at installing Solar in our house in SOCAL, but the big question we have is HOW MUCH? Ok so you are eventually saving money on the monthly electric bill but you have to buy or lease the panels so doesn't it come out even to what you are paying now? Do you have to qualify to lease or buy the panels? So lets say I am averaging $250 a mth& after installing the panels pay $100 but I have to pay additional bill of leasing buying the panels of $150 per months so to be it evens out yes?
What would it cost to build a solar energy plant that has 1 sq km of solar panels (excluding land)?
The solar panels themselves have a capacity of around 150 watts per square meter (excluding service areas and the space required by other equipment).One square kilometer of solar panels (one million square meters) can fit 150 million watts of capacity, or 150 MW.Utility-scale solar farms are now being installed for around $1/watt throughout the world, so this project would cost around $150 million.Land is typically below 5% of the total cost. In this case 5% is equivalent to $7.5 million, leaving an approximate cost of $142.5 million.
How is Solar Energy efficient, and cost effective? ?
Nobody here has ever posted a site that proves oil is subsidized. They can find where it gets tax breaks which are extended to all business, but not 1 piece of fact on subsidizing. Oil companies receive grants and funding for research of clean energy or to help pay for plant modification under laws. Since all companies, including bread factories and dry cleaners got similar money back from the government, oil companies were not singled out and given subsidies. Solar PV panels cost $8000 per kilowatt and will generate about 5 kilowatt-hours per day for that investment. 5 kw-hr is about $.60/day or about $300 per year in savings. This means at about the time the panel is paid for, you will have to buy a new one. Think about buying a house and the day you get it paid for, it falls apart and you can't live in it anymore. So, the government gives you money. Where do they get the money, from your neighbors. Then, lets think about this. Only the rich can afford a $100,000 system, so the rich will buy them, and then all the poor and middle class will pay for them. BUT if the government taxes the rich to much, they won't be able to buy them.
Pros and cons to solar power?
PROS: Solar panels give off no pollution, the only pollution produced as a result of solar panels is the manufacturing of these devices in factories, transportation of the goods, and installation. The production of energy from the use of fossil and some renewable fuels (e.g. wind turbines) can be noisy, yet solar energy produces electricity very quietly. One of the great pros of solar energy is the ability to harness electricity in remote locations that are not linked to a national grid. A prime example of this is in space, where satellites are powered by high efficiency solar cells. The installation of solar panels in remote locations is usually much more cost effective than laying the required high voltage wires. Solar energy can be very efficient in a large area of the globe, and new technologies allow for a more efficient energy production on overcast/dull days. Solar panels can be installed on top of many rooftops, which eliminates the problem of finding the required space for solar panel placement. Another great pro of solar energy is the cost. Although the initial investment of solar cells may be high, once installed, they provide a free source of electricity, which will pay off over the coming years. The use of solar energy to produce electricity allows the user to become less dependent on the worlds fossil fuel supplies. CONS:The major con of solar energy is the initial cost of solar cells. Currently, prices of highly efficient solar cells can be above $1000, and some households may need more than one. This makes the initial installation of solar panels very costly. Solar energy is only able to generate electricity during daylight hours. This means for around half of each day, solar panels are not producing energy for your home. The weather can affect the efficiency of solar cells. Pollution can be a con of solar energy, as pollution levels can affect a solar cells efficiency, this would be a major con for businesses or industry wishing to install solar panels in heavily polluted areas, such as cities. Hope this helped! :)
How much investment is needed to set up one MW solar power plant in Patna? How much revenue income can I expect from such a plant if we sell electricity to the Bihar government?
Cost of 1 MW solar plant varies from INR 5.5–6.5 cr. depending upon the quality of components used. Then there is cost of land (usually 5% of total project cost) and O&M (13 lakh/MW).Bihar receives decent radiation.So, 1 MW would generate approx. 1.5 million units annually.Bihar govt. is promoting solar sector and investing in solar project will be profitable. Tariff for Rooftop Solar PV and Small Power Projects is 6.96(without AD) and 6.29(with AD). No idea about tariff for large scale projects.
Why can't solar energy be used for all our energy needs?
First off solar is very expensive to use. So it would drive up our cost of living drastically. That alone answers your question. http://greenecon.net/understanding-the-c... Second you would have to cover the whole world with solar panels to get enough energy to supply all of our needs. Then you would have place to grow crops. So everybody in the world would die. Solar does not work at night and is not practical in the very northern climates. When you get above the arctic circle it's night time for most of the winter. You can't store that much electricity in batteries to last that long. Where are you going to get enough batteries to store all the energy needed at night. That is a lot of mining you are going to have to do. Stick with coal. It's cheap and abundant.
What do you think US energy policy should be?
Invest heavily in clean, renewable energy, including solar, wind, and geothermal. Give federal rebates for individuals and companies who invest in renewable energy. Mandate auto makers to increase fuel efficiency and alternate fuel vehicles. Invest in both public transportation and bike friendly infastructure. Tax gas more so people will have a financial incentive to reduce their driving and buy fuel efficient vehicles. Give tax breaks for alternate fuel vehicles. Limit our imports of oil from other countries. If our government would be willing to make real changes like these I wouldn't oppose offshore drilling or nuclear plants.
