What is Solar Energy?

Solar energy is a method to convert light energy into electricity simply by using a device or method that harnesses solar power. There are usually 2 ways many of us can convert solar energy into electrical power, we can both convert it passively or harvesting solar power without the particular utilization of any mechanised device or make an effort to by using a mechanical device.

There are a few varieties of energy of which the we can get coming from the sun:

Solar Light Energy. Photovoltaics is a method to convert solar energy into electric power by gathering photons or the little packets of power within the sun's light. We can make use of this kind of strength to gather the light-weight of the sun and use that to power typically the appliances within our houses.

Solar panels convert light energy in order to electricity by means of interconnected photovoltaic silicon(solar cells) arranged in a module or with an assortment.

For a solar panel to function, it is installed in order to in which the sun offers most adequate lighting in your town. A solar panel only creates 12 volt associated with DC, therefore, a great inverter is wanted to convert DC to AC. ALTERNATING CURRENT is an electric powered current corresponding to 110/100/220 volt (depends upon country) which kind of voltage is needed to power up any kind of appliances inside typically the home.

Advantage

- Less maintenance due to the fact it gathers electrical energy passively.
- Totally free source of fuel for energy gathering.
- Endless present of fuel.
- Long operational lifestyle as it will not have any mechanical device that may wear and tear due to frequent operations.
- Preserves electricity bill.

Disadvantage

- High primary cost. ROI will be achieved in about 1 to 5 years.
- Have got to be attached to places where 100% from the sun's light is usually achieved. A cloudy location means a new decrease in energy output.
- Energy can simply gained during the day yet we can mount batteries so that will we can nevertheless use solar power even when the sun is simply not way up.

Solar Thermal Strength. Harnessing solar vitality but it is usually converted to high temperature energy. Examples associated with which is using the sun to cozy a home's interior environment, heat normal water or even a swimming swimming pool.

A solar thermal system is a new like a solar panel but it can goal is to gather the sun's heat. Instead of mirrors and silicon solar panels, it uses the black colored sections with a temperature collector and alternatively of generating electricity, that is converted heat energy.

The original source


-- Unlike solar panels, it does not require adequate solar light to collect solar energy.
-- It is utilized passively meaning less maintenance compared to be able to mechanical type regarding solar power devices.
- Endless supply of energy as the sun does not really decrease nor deplete it's energy charge.
- Saves energy and/or electricity needed to heat the water or maintain your indoor atmosphere warm.

Disadvantage

: Will only function in the daytime when the sun is increasing.
- Not advised about shady or gloomy locations.
- The initial cost will be high but generally there are other choices like recycling that can decrease the entire initial cost.

Concentrated Solar Power. Located Solar Power uses lenses or refractive mirrors to concentrate light energy in to a small region to generate a very high temperatures that powers boils the water and even powers the vapor turbine thereby creating electricity.

Concentrated solar power systems are not comparable to solar panels even though it shows up as if even though it is using a solar panel but it is not a solar panel but a reflective panel all directed at a tower thus generating heat high enough to make heavy steam turbines work.

Solar cooking is the example of centered solar power. It uses a reflective oven that gathers typically the sun's light and after that aims it in a specific location in order to concentrate light for that reason generate heat.

Focused Solar Power can also be used to create electricity. A bowl or possibly a parabolic trough may be used on homes which require a new larger space plus because concentrated solar power uses heavy steam and an electrical generator, nevertheless the downside is definitely it might always be too loud for neighbors.

Advantage

-- Limitless fuel supply.
- Saves on electricity bill.

Downside

- Too high decibel and not neighbor-friendly
- Too bulky if used in the home, requires larger place.
- Must always be on constant sun rays to get 100% power.
- Has the mechanical device plus uses water to create electricity therefore calls for more maintenance.
- The sun is definitely not available at night.

Conclusion

Solar energy is free plus renewable however its primary cost is higher. But if a person think carefully, the one particular time price of solar panels such as is sufficient enough in order to save you at least 40% of your electrical power consumption per calendar month that will carry on for years in addition to years.
