Unknown. After a research during last months, I found today panels have approximately an efficiency of 15% (very low). NASA has make some experiments lead to a result of 25%. This because no solar panel use all wavelengths of light (colors) which the sunlight have a lot.
Today the most efficient way is steam produced indirectly from sun.

The price per watt is a figure of merit, but is not how the panels are sold, any more than a gallon of gas is sold by how many miles you will be able to drive with it. You buy the gas at a certain price, then how many miles you actually get depends on what car you drive, and other factors.

In the same way, a certain model of panel is sold for an agreed-upon price. Let’s say it’s a 200-watt panel, and sold for 0. If the panel was rated in accordance with established standards, that means the panel will deliver 200 watts under ideal sunlight and temperature (that only happens about an hour a day, if that). So you can calculate that the price was 400/200 = per watt.

If the strong sunlight shines on the panel for 1 hour, then the energy produced is 200 watt-hours. This is where many people get confused. A watt is different from a watt-hour. A watt is a unit of power, like how strong a man is. A watt-hour is a unit of energy, like the work accomplished by that man in 1 hour.

The watt-hours or kilowatt-hours delivered are what light the rooms, run the appliances, or are sold to the power company. Getting those is a matter of having a good geographic location and installation.

I live in west Texas where it never rains and its always windy

Hope it’s not cloudy without wind for a while, you’ll be left with warm food and darkness.

An air conditioner/heater would be such a huge load on the system, wind/solar most likely don’t make sense for an individual, unless you’re on a lake or in California where it’s sunny everyday.

You would need around 200 W for a fridge, 100 W for small lights, and….500 W (?) for heating/air….so you’re looking at some pretty big batteries!! Every 2 hours you will use at least 1.5 kWh of energy.

Answer by Bobbie
Enacted in August 1997, this personal income tax credit originally applied to expenditures on solar-electric (PV) equipment used on residential property. The credit, equal to 25% percent of the cost of equipment and installation, was expanded in August 2005 to include solar-thermal equipment. The solar-thermal provisions apply to taxable years beginning on and after January 1, 2006. The credit is capped at ,750 for solar-energy systems placed in service before September 1, 2006, and capped at ,000 for solar-energy systems placed in service on or after September 1, 2006.
Solar-energy equipment is defined as “an arrangement or combination of components utilizing solar radiation, which, when installed in a residence, produces energy designed to provide heating, cooling, hot water or electricity.” The credit may not be used for pool heating or other recreational applications. Any amount of credit that exceeds a taxpayer’s liability in a given tax year may be carried forward for the five following taxable years. Any portion of the system cost provided by a non-taxable federal, state, or local grant is not eligible for this credit.
Systems must comply with the 10 kW capacity limit on residential, net-metered solar-energy systems*. In 2007, legislation was passed increasing the capacity limit to 50 kW for condominiums and cooperative housing associations. In addition, members of condominium management associations and tenant stockholders of cooperative housing associations are now allowed to claim a proportionate share of the total system expense towards the tax credit. These changes took effect beginning in the 2007 tax year, but as with other portions of the tax credit, they do not have an expiration date.
*The language of the tax credit generally requires that PV systems conform to the state’s net metering law, thereby limiting system size to 10 kW. In August 2008, the state net metering law was expanded by S.B. 7171 to permit net metering for residential PV systems up to 25 KW. It is unclear at this point whether the state intends for the new net metering limits to apply to the tax credit described above. The 2009 Solar Tax Credit Form IT-255 does not specifically address this issue.

Hi
There are two types of solar panel installations one is domestic (the one you are using in your home) and another one is commercial (used for business like your school)

Domestic installation are up to 4kW and usually you can install them without any special permits. Installation process takes about 2 days if you want to find out benefits of that kind of installation go to
http://www.tudorsolar.com/cost-calculator/ and enter your postcode and the size of the system you would like to install ( ex: 4.00kW). There is also a lot of useful information you could use for your project like..
-Why solar?
-How much you can save and what are your benefits.

Political concerns… Government encourage people to install solar panels. The offer FIT’s (Feed in tariffs for 25 years (UK)) and also grants for some businesses and privates houses. Government will spend millions on this project. They also have the right to pick the sup-players which mean that that some small businesses will get bust.

Concerns:
Electricity prices will go up. Electric providers will have to make up the lost in business by putting prices up in UK this year 18% for electricity and 16% for gas.

Solar panels are now produced faster then ever. They produce clean pollution free energy however there is waste created during manufacturing process.

After Solar Panel life time expire this is about 30-40 years. It will turn to the wast which will have to be utilise.

Solar panels do save a lot of money but to start with you have to have money to install them in first place. If you don’t you will be the one who will have to pay electricity for the people who had many for it. The gap between poor and wealthy will get even bigger.

You can, but you wouldn’t be getting all the power possible. I’m guessing the monocrystalline is much more efficient than the amorphous panels, but in parallel you’d only be getting the power output of the lowest efficiency cell.

It is a good decision. If I were you I would prefer the vacuum tube solar collector which is very efficient although it is about 20% more expensive but in no time you will recover the additional cost. I have one and I have never needed to use the electrical backup even with three or four overcast days. Even with no sunlight they will obtain heat from the infrared waves of the light. I live in the tropics but it will be even more useful for those living in th e temperate zone.

Answer by Jason Amoratis
at most 4,985 kWh daily
or
17,940 kJ daily

this amounts to an average of 207 kW of power every hour, which should require over 4,000 m^2 (43,000 ft^2) of installed PV panels.
