replaceable Energy: Solar Energy
What is Solar Energy?
Solar energy is a way to transform light energy into electricity by using a device or medium that harnesses solar strength. There are 2 ways we can transform solar energy into electricity, we can either transform it passively or harvesting solar strength without the use of any mechanical device or actively by using a mechanical device.
There are 3 types of energy that the we can get from the sun:
Solar Light Energy. Photovoltaics is a way to transform solar energy into electricity by gathering photons or the small packets of energy inside the sun’s rays. We can use this kind of energy to gather the light of the sun and use it to strength the appliances inside our homes.
Solar panels transform light energy to electricity by method of interconnected photovoltaic silicon(solar cells) arranged in a module or by an range.
For a solar panel to work, it is installed to where the sun has most adequate light in your area. A solar panel only generates 12 volt of DC, consequently, an inverter is needed to transform DC to AC. AC is an electric current equal to 110/100/220 volt (depends on country) and this kind of voltage is required to strength up any appliances inside the home.
– Less maintenance because it gathers electricity passively.
– Free source of fuel for energy gathering.
– Endless supply of fuel.
– Long operational life as it does not have any mechanical device that may use and tear due to repeated operations.
– Saves electricity bill.
– High initial cost. ROI will be achieved in about 1 to 5 years.
– Must be installed on places where 100% of the sun’s light is achieved. A cloudy location method a decline in strength output.
– strength can only attained during the day but we can install batteries so that we can nevertheless use solar energy already when the sun is not up.
Solar Thermal Energy. Harnessing solar energy but it is converted to heat energy. Examples of which is using the sun to warm a home’s indoor ecosystem, heat water or a swimming pool.
A solar thermal system is a like a solar panel but it’s goal is to gather the sun’s heat. Instead of mirrors and silicon solar panels, it uses a black colored panels with a heat collector and instead of generating electricity, it is converted heat energy.
– Unlike solar panels, it does not require adequate solar light to gather solar energy.
– It is used passively meaning less maintenance compared to mechanical kind of solar strength systems.
– Endless supply of energy because the sun does not decline nor deplete it’s energy rate.
– Saves fuel and/or electricity required to heat a water or keep your indoor ecosystem warm.
– Will only function during the day when the sun is rising.
– Not recommended on shady or cloudy locations.
– The initial cost is high but there are other options like recycling that can decline the total initial cost.
Concentrated Solar strength. Concentrated Solar strength uses lenses or reflective mirrors to focus light energy into a small area to generate a very high temperature that powers boils the water and powers the steam turbine thereby generating electricity.
Concentrated solar strength systems are not similar to solar panels although it appears as if though it is using a solar panel but it is not a solar panel but a reflective panel all aimed at a tower thereby generating heat high enough to make steam turbines work.
Solar cooking is an example of concentrated solar strength. It uses a reflective cooker that gathers the sun’s light and then aims it at a specific location to concentrate light consequently generate heat.
Concentrated Solar strength is also used to generate electricity. A dish or a parabolic trough may be used on homes but they all require a larger space and because concentrated solar strength uses steam and a generator, but the downside is it might be too loud for neighbors.
– Limitless fuel source.
– Saves on electricity bill.
– Too loud and not neighbor-friendly
– Too bulky if used at home, requires larger space.
– Must be on continued sunlight to acquire 100% strength.
– Has a mechanical device and uses water to generate electricity consequently requires more maintenance.
– The sun is not obtainable at night.
Solar energy is free and replaceable however its dominant cost is high. But if you think carefully, the one time cost of solar panels for example is sufficient enough to save you at the minimum 40% of your electricity consumption per month that will go on for years and years.
LEED, an internationally recognized green building system rates a building or a house that meets its standards for being ecosystem friendly and conserves energy. With your green aims, plus using all the method necessary to save on electricity bills and reduce carbon dioxide emissions, it’s a waste if you do not get your home or building be LEED certified. Who knows you might get a LEED Platinum rating for your efforts.
