What's Solar Energy?
Solar energy is actually a method to convert light energy into electricity by using a device or medium that harnesses solar power. You will discover 2 techniques we are able to convert solar energy into electricity, we can either convert it passively or harvesting solar power without having the use of any mechanical device or actively by using a mechanical device.

You'll find 3 kinds of energy that the we can get from the sun:
Solar Light Energy. Photovoltaics is usually a solution to convert solar energy into electricity by gathering photons or the compact packets of energy inside the sun's rays. We can use this kind of energy to gather the light of your sun and use it to power the appliances inside our homes.
Solar panels convert light energy to electricity by indicates of interconnected photovoltaic silicon(solar cells) arranged in a module or by way of an array.
For any solar panel to work, it's installed to exactly where the sun has most sufficient light within your region. A solar panel only generates 12 volt of DC, hence, an inverter is necessary to convert DC to AC. AC is definitely an electric current equal to 110/100/220 volt (depends upon nation) and this kind of voltage is needed to power up any appliances inside the home.
Benefit
- Much less upkeep since it gathers electricity passively.
- Free source of fuel for energy gathering.
- Endless supply of fuel.
- Extended operational life as it does not have any mechanical device that may perhaps put on and tear as a result of repeated operations.
- Saves electricity bill.
Disadvantage
- High initial price. ROI are going to be accomplished in about 1 to 5 years.
- Must be installed on places where 100% from the sun's light is achieved. A cloudy place signifies a reduce in power output.
- Power can only gained throughout the day but we can set up batteries in order that we are able to nonetheless use solar energy even when the sun isn't up.
Solar Thermal Energy. Harnessing solar energy nevertheless it is converted to heat energy. Examples of which can be using the sun to warm a home's indoor atmosphere, heat water or perhaps a swimming pool.
A solar thermal system is really a like a solar panel but it's objective is always to gather the sun's heat. As opposed to mirrors and silicon solar panels, it uses a black colored panels with a heat collector and rather than producing electricity, it is actually converted heat energy.
Advantage
- In contrast to solar panels, it does not call for sufficient solar light to gather solar energy.
- It is actually used passively which means significantly less upkeep in comparison to mechanical type of solar power systems.
- Endless supply of energy mainly because the sun doesn't lower nor deplete it really is energy rate.
- Saves fuel and/or electricity necessary to heat a water or keep your indoor atmosphere warm.
Disadvantage
- Will only function throughout the day when the sun is rising.
- Not suggested on shady or cloudy areas.
- The initial cost is higher but you will find other options like recycling that could reduce the total initial cost.
Concentrated Solar Power. Concentrated Solar Power uses lenses or reflective mirrors to focus light energy into a small area to create an extremely high temperature that powers boils the water and powers the steam turbine thereby producing electricity.
Concentrated solar power systems aren't comparable to solar panels although it appears as if though it can be using a solar panel however it will not be a solar panel but a reflective panel all aimed at a tower thereby generating heat high adequate to create steam turbines work.
Solar cooking is an instance of concentrated solar power. It uses a reflective cooker that gathers the sun's light after which aims it at a certain location to concentrate light as a result create heat.
Concentrated Solar Power can also be used to produce electricity. A dish or even a parabolic trough may very well be used on homes however they all demand a larger space and due to the fact concentrated solar power uses steam in addition to a generator, however the downside is it may be too loud for neighbors.
Benefit
- Limitless fuel source.
- Saves on electricity bill.
Disadvantage
- As well loud and not neighbor-friendly
- Too bulky if used at home, calls for larger space.
- Will have to be on continual sunlight to obtain 100% power.
- Includes a mechanical device and uses water to generate electricity thus calls for much more maintenance.
- The sun just isn't out there at night.
Conclusion
Solar energy is free and renewable having said that its primary expense is high. But for those who think meticulously, the one time cost of solar panels as an example is sufficient adequate to save you no less than 40% of one's electricity consumption monthly that can go on for years and years.
LEED, an internationally recognized green building system rates a developing or perhaps a house that meets its requirements for becoming atmosphere friendly and conserves energy. With your green aims, plus using all of the implies necessary to save on electricity bills and reduce carbon dioxide emissions, it really is a waste when you do not get your home or constructing be LEED certified. Who knows you could get a LEED Platinum rating for your efforts.
