Solar Power Electricity

How does solar energy to generate power in use?

I mean, how solar energy to generate electricity and heat? This is for a class, then I would appreciate it if you were positive. Consider the websitre or book you use. THANK YOU!

Start with the site Wikipedia. So look for specific purposes: The energy of the sun gives us light and heat. more energetic photons of light can be used for a few electrons accident of atoms, electrons can flow through electrical cables (photovolatic cells). The sun's heat evaporates water from oceans, forms clouds, rain on both sides of the mountains, streams, creeks, rivers … Solar energy is "stored" in the streams as water flows into the ocean. Us intercept to run turbines (hydro-). Plants absorb the energy of sunlight (chlorophyll). In trees, it becomes fibrous material that, when buried for thousands of years to become coal. When we burn coal, to "liberate" stored solar energy. Animals eat the plants (which in turn represent stored solar energy), and when buried for thousands of years, back to oil.

Anyone know the price of solar – thermal and photovoltaic – the price system and a micro wind power system?

I'm doing research on installing a fuel cell inside a house and want to compare the price of this system with a PV and solar thermal energy system and also the price micro wind energy for use in residential buildings. Prices will be installed or adequate KW KWh … source? Thanks

What should be an answer for easy, because it will cost $ 14/watt for $ 7/watt solar and wind energy for is not so easy in fact. There are "two" major challenges for understanding and PV system costs of wind power and energy? # 1. POWER is difficult to discover. You buy these systems depending on their nameplate "value", but if you really care about their total electricity generation: To explain: Each of these systems, solar and wind, will be "evaluated" for its ability to produce energy. This classification is known as face value and the purchase of a "90 wattage of solar panels, and 90 watts is the maximum power can produce the panel in a sunny afternoon. Also, the 1 kW (nominal) wind turbine will be "evaluated" the maximum power that can generate enough wind on the high (typically 30 mph sustained). If you're really using these power generation systems, the nominal value is good to know that the total power that is faced in the system, but not very useful for determining the energy production. What really counts is watts / year does not watt for the best. To determine your estimated annual per watt of solar or wind energy is very difficult and depends on the sun and wind conditions where they live and how to install these. In general, a solar system with a nominal power of 3 kW will produce about 4000 kW / h per year, "Sun" good "(U.S. South), and a 3 kW wind turbine will produce about 6000 kW / h in "good wind" (Wind-class three areas.) A map of wind classes can be found at AWEA.org. # 2. The price is hard to find. Even if you do some math and calculate the production of energy for your system, there is a price "easier" to complete any of them. Solar panels require installation, DC-AC inverters, network connection systems and / or battery systems. wind systems also require the installation, including the work of the tower foundation and potentially costly, if you want to get the turbine in high winds, solar inverters network and batteries, etc. It is not unusual WANT solar or wind installation costs to double or triple the purchase of the panels or turbines themselves. I wanted to know what to buy, the answer is: if it is really sunny and windy Otherwise, use solar, windy (branches offer singing in the branches) the wind. then jeremy

Can solar panels to heat pool be used for other household purposes?

Hi there, my father just bought a house that has solar panels on the roof to heat the water for his pool. The water goes through pipes by the panels and flows back into the pool. I was wondering if there is any way to use that solar energy for other areas of the house. The panels were put in when the house was built in the mid 80’s and the house is in Central Florida/E. Orlando.

Thanks in advance!

What kind of solar power incentives are offered in Arizona?

I am looking into solar power and land prices are cheap in AZ. Does anyone know what kind of Federal or State incentives are offered for Solar power?

Determining if solar power can pay off

Here are some typical questions that people who are considering putting in solar power need to ask.

I am considering a solar panels. How can I tell if my area gets enough solar energy a year to be worthwhile?

I want to know how I can determine my area’s (Rochester NY) yearly solar energy output to see if it would make economic sense to install solar panels. Any websites or resources where I can look?

which is cheaper defeat for the generation of electricity from solar photovoltaic and solar thermal?

is cheaper to defeat to the generation of electricity from solar photovoltaic and solar thermal?

For the generation of large-scale electricity, energy Thermal solar is more practical and efficient. the efficiency of photovoltaic solar energy is still only 15% less than you pay more for greater efficiency. EDIT ************* And it is written: 'path'

Solar Power Company

What is the name of the solar energy company that invested in Google?

Google says it has invested in each company to buy some. I have heard say they buy computers and printers and key cards for use in your business. It makes me think that companies have invested in a team? I bet that even cars and trucks vans and maybe even the name in google them .. They should have invested in Chevy, Ford and other automakers as well. If solar installed in your building, not purchased in a solar energy company.

Solar Panel

It will be a discharge of a battery of solar panels at night without special equipment?

I am interested in buying a 5-watt solar panel for connection Cars to a battery.

You can get one with a diode. This will stop the discharge. Why do you want to charge the battery with a panel solar? You may charge only the battery and make it wear out sooner. It's best to leave the car to charge the alternator for you. Unless, of course, has other electrical items connected to drain the battery.
