Green Energy: Solar Energy
What is Solar Energy?

Solar energy is a way to transfer light energy in to electricity by using a device or perhaps medium that harnesses solar power. There are 2 ways we can convert solar energy into electricity, we are able to either convert it passively or harvesting solar power minus the use of any kind of machine or positively using a mechanical device.

There are three or more types of energy the we can easily get from the particular sun:

Solar Lighting Energy. Photovoltaics is a way to convert solar energy into electrical energy by gathering photons and also the small bouts of energy inside the sun's rays. We all can use this specific sort of energy to gather the light involving the sun and use it to power the particular appliances inside our own homes.

Solar panels convert light energy to electricity by simply means of connected with each other photovoltaic silicon(solar cells) arranged in the module or through an array.

For a solar panel to work, that is installed in order to where the sun has most satisfactory light in your own area. A solar panel only produces 12 volt associated with DC, consequently , a great inverter is necessary to convert DC to AIR CONDITIONING UNIT. AC is surely an electric current equal to be able to 110/100/220 volt (depends on country) and even this sort of voltage is required to power up any appliances inside the home.

Benefit

: Less maintenance because it gathers electric power passively.
- No cost source of fuel for energy accumulating.
- Endless supply of fuel.
- Long operational existence as it really does not have any kind of mechanical device that could wear and tear due to frequent operations.
- Saves electricity bill.

Drawback

- High start up cost. ROI will probably be achieved in regarding 1 to five years.
- Need to be attached to spots where 100% from the sun's light is usually achieved. A over cast location means a decrease in power output.
- Power can only gained in the course of the day yet we can mount batteries so that we can continue to use solar energy even when the particular sun is not really upwards.

Solar Thermal Energy. Harnessing solar energy but it is definitely converted to warmth energy. Examples regarding which is using the sun to comfortable a home's indoor environment, heat normal water or even a swimming pool area.

A solar energy system is a like a solar panel but it's goal is to gather the sun's heat. Instead of magnifying mirrors and silicon solar panels, by using some sort of black colored panels with a heat up collector and alternatively of generating electricity, it is converted heat energy.

Advantage

- Unlike solar panels, it does not really require adequate solar light to accumulate solar energy.
: It is utilized passively meaning much less maintenance compared to be able to mechanical type involving solar power devices.
- Endless offer of energy because the sun does certainly not decrease nor reduce it's energy charge.
- Saves energy and/or electricity essential to heat a water or keep your indoor surroundings warm.

Disadvantage

-- Will only function throughout the day when the sun is growing.
- Not recommended in shady or gloomy locations.
- The initial cost is high but generally there are other alternatives like recycling which could decrease the full initial cost.


Focused Solar Power. Focused Solar Power uses lenses or refractive mirrors to target light energy in to a small area to generate some sort of very high temp that powers comes the water and powers the heavy steam turbine thereby producing electricity.

Concentrated solar power systems are not just like solar panels though it appears as if even though it is employing a solar panel but it is simply not a solar panel but a refractive panel all geared towards a tower thus generating heat high enough to make heavy steam turbines work.

Solar cooking is an example of concentrated solar power. By using a reflective cooker that gathers the sun's light then aims it at the specific location in order to concentrate light for that reason generate heat.

Centered Solar Power is likewise used to make electricity. A plate or perhaps a parabolic trough can also be used on houses but they all require the larger space in addition to because concentrated solar power uses vapor and an electrical generator, but the downside is it might end up being too loud intended for neighbors.

Advantage

- Limitless fuel supply.
- Saves in electricity bill.

Drawback

- Too loud and not neighbor-friendly
- Too large if used in your own home, requires larger area.
- Must be on website to get 100% power.
- Has the mechanical device and uses water to create electricity therefore needs more maintenance.
instructions The sun is not available at night.

Conclusion

Solar energy is free and renewable however it is primary expense is high. But if an individual be cautious, the a single time cost of solar panels such as is sufficient enough to save lots of a person at least forty percent of your electric power consumption per calendar month that will carry on for years in addition to years.
