What is Solar Power?

Benefits of Wind Power & Cost Of Wind Power

Wind power is one environmental friendly power source that we are able to never forget. Same like solar energy, it is an unlimited supply, extraordinarily clean and typically available. A small scale wind power generator for home is easy to build and can bring us a lot of benefits.

The cost of building such a generator is also relatively inexpensive with common material available is the shop. We need to make blades, and then connect it to make a rotor that can transform a dynamo, and create electricity from there. Installing a wind power generator can give us a lot of advantages such as : Environment protection It decreases our dependent to fossil fuel.

Fossil fuel is known to contribute greenhouse effect. Many power generation plant still using coal, diesel or natural gas to burn the water and run the steam turbine and emit carbon dioxide. By employing wind to generate electric power, it is direct, and we get the electricity right away. Save Money you'll achieve this by saving the electricity bill every month, continuously.

About the author: As an expert it's quite easy to build abundant sources of green energy. My aim is to direct everyone to easy and simple solutions that save the earth while saving money as well.

Frequently Asked Questions

  1. QUESTION:
    How exactly do wind and solar power companies make their money?
    I only invest in small-cap energy based companies like oil, gas, petroleum, and more recently, wind and solar power.

    What I would like to know is how exactly do wind and solar power companies make their money? Please, I'd like to understand the industry a bit better. Thanks!

    • ANSWER:
      Your question is fairly general. Perhaps you would like to read these introductory articles and then post more specific questions:

  2. QUESTION:
    How much does solar power cost in australia ?
    I am considering getting solar power for my house. Does anybody have an appox idea how much it would cost to fit my house with this. We just have a typical 3 bedroom house. I have also heard that if your solar panels produce more energy than what you use, it will go back into the power grid, and the energy company will pay you. Is this right? If so any ideas on how much you get back?Thanks

    • ANSWER:
      The amount you get back (and yes if you put power back into the grid they will pay you) depends exactly how much you put back, either way, the power company will be paying you and some money is better than no money.

      Solar modules come in two distinct categories - crystalline silicon and amorphous silicon thin film. Both amorphous and crystalline technologies are commonly used in efficient grid connected and stand alone installations.

      Mono and poly crystalline modules usually have 36 solar cells in a 9 x 4 matrix connected in series to provide an output voltage suitable for battery charging. A typical module will provide a peak power output voltage of 17V and output current of 4.7A under optimum conditions, giving a rating of 80 Watts peak (Wp). Modules can be connected in series or parallel to form an array to provide higher voltage and current outputs as required.

      Crystalline solar modules are covered with tempered glass on top and a tough ethylene vinyl acetate (EVA) material at
      the back. The glass and backing material protect the solar cells from moisture.

      The best way to find out is contacting environmental groups or even the power company themselves. Costs vary, and so this is an issue that is best left when you find the appropriate group.

  3. QUESTION:
    What is the name of a product that can solar power charge your rechargeable batteries?
    I use rechargeable batteries a lot, but they run out fast. I want to use solar power to recharge my batteries.

    Is there a certain product I can hook up to any rechargeable battery? What is it called?

    Thank you in advance.
    has some what? Where's the name of the product?

    • ANSWER:
      It would be called a "Solar Battery Charger".
      You also see them on LED Solar Powered Landscape Lights. The LED lights are powered by a rechargable AA battery, and the light power will eventually completely discharge by the end of night.
      The small solar panel (on top) will again re-charge the rechargable batteries during the day, and when the sun goes down, the LED lights come on once again. This cycle repeats daily.

      Some info on Solar Battery Chargers, as well as places to buy them, are listed below:

  4. QUESTION:
    What is capacity hour rate for solar power batteries?
    I'm looking a battery for use with solar power and it has the following specs.

    Volts 12
    Capacity @ 20-hr rate 120
    Capacity @ 100-hr rate 145

    How does this translate into running a 1000 watt appliance and how long you can run it with this battery.

    • ANSWER:
      Watts = Volts * Amps.
      So a 12 volt battery supplying 10 Amps is producing 120 Watts of power.
      Batteries are rated in Amp-Hours. For example one battery might be rated at 100 Amp-Hours. That would mean it could supply 1 Amp for 100 hours or 2 Amps for 50 hours. But it could probably not supply 100 Amps for 1 hour. Batteries work better at low rates of use. Your examples are 20 hour rate gives 120 Amp-Hours, meaning it can supply 6 Amps for 20 hours (6 Amps times 20 hours = 120 Amp-Hours), but if you drain it more slowly, taking 100 hours instead of 20, it will give you 145 Amp-Hours, which would be 1.45 Amps for 100 hours.

      To get Watt-Hours, multiply by the number of volts. Most such batteries are 12 volt (but not all are so check). So a 12 volt battery that has a 120 Amp Hour capacity has a 12 * 120 = 1,440 Watt-Hour capacity. Since one kilowatt (kW) is 1,000 Watts, that would be a 1.44 kilowatt-Hour (kWh) battery. You electric bill is usually in units of kWh. Check your electric bill to see how many kWh a month you use, then divide by 30 to get the number per day. That will give you an idea of how many batteries you need to store enough energy to make it through the night if you are off grid and relying on solar panels for all your power. I suspect you will be shocked at the number of batteries needed.
