What’s Photo voltaic Vitality?

Photo voltaic power is a method to convert gentle power into electrical energy through the use of a tool or medium that harnesses solar energy. There are 2 methods we are able to convert photo voltaic power into electrical energy, we are able to both convert it passively or harvesting solar energy with out the usage of any mechanical machine or actively through the use of a mechanical machine.

There are 3 varieties of power that the we are able to get from the solar:

Photo voltaic Gentle Vitality. Photovoltaics is a method to convert photo voltaic power into electrical energy by gathering photons or the small packets of power contained in the solar’s rays. We are able to use this type of power to assemble the sunshine of the solar and use it to energy the home equipment inside our houses.

Photo voltaic panels convert gentle power to electrical energy via interconnected photovoltaic silicon(photo voltaic cells) organized in a module or by means of an array.

For a photo voltaic panel to work, it’s put in to the place the solar has most sufficient gentle in your space. A photo voltaic panel solely generates 12 volt of DC, due to this fact, an inverter is required to transform DC to AC. AC is an electrical present equal to 110/100/220 volt (is determined by nation) and this type of voltage is required to energy up any home equipment inside the house.


– Much less upkeep as a result of it gathers electrical energy passively.

– Free supply of gas for power gathering.

– Limitless provide of gas.

– Lengthy operational life because it doesn’t have any mechanical machine which will put on and tear resulting from repeated operations.

– Save electrical energy invoice.


– Excessive preliminary value. ROI can be achieved in about 1 to five years.

– Have to be put in on locations the place 100% of the solar’s gentle is achieved. A cloudy location means a lower in energy output.

– Energy can solely gained throughout the day however we are able to set up batteries in order that we are able to nonetheless use photo voltaic power even when the solar is just not up.

Photo voltaic Thermal Vitality. Harnessing photo voltaic power however it’s transformed to warmth power. Examples of which is utilizing the solar to heat a house’s indoor atmosphere, warmth water or a swimming pool.

A photo voltaic thermal system is a like a photo voltaic panel however it’s objective is to assemble the solar’s warmth. As an alternative of mirrors and silicon photo voltaic panels, it makes use of a black coloured panels with a warmth collector and as a substitute of producing electrical energy, it’s transformed warmth power.


– Not like photo voltaic panels, it doesn’t require sufficient photo voltaic gentle to assemble photo voltaic power.

– It’s used passively which means much less upkeep in comparison with mechanical sort of solar energy techniques.

– Limitless provide of power as a result of the solar doesn’t lower nor deplete it is power charge.

– Saves gas and/or electrical energy required to warmth a water or preserve your indoor atmosphere heat.


– Will solely operate throughout the day when the solar is rising.

– Not beneficial on shady or cloudy places.

– The preliminary value is excessive however there are different choices like recycling that may lower the full preliminary value.

Concentrated Photo voltaic Energy. Concentrated Photo voltaic Energy makes use of lenses or reflective mirrors to focus gentle power right into a small space to generate a really excessive temperature that powers boils the water and powers the steam turbine thereby producing electrical energy.

Concentrated solar energy techniques will not be much like photo voltaic panels though it seems as if although it’s utilizing a photo voltaic panel however it’s not a photo voltaic panel however a reflective panel all geared toward a tower thereby producing warmth excessive sufficient to make steam generators work.

Photo voltaic cooking is an instance of concentrated solar energy. It makes use of a reflective cooker that gathers the solar’s gentle after which goals it at a particular location to pay attention gentle due to this fact generate warmth.

Concentrated Photo voltaic Energy can also be used to generate electrical energy. A dish or a parabolic trough could also be used on houses however all of them require a bigger house and since concentrated solar energy makes use of steam and a generator, however the draw back is it may be too loud for neighbors.


– Limitless gas supply.

– Saves on electrical energy invoice.


– Too loud and never neighbor-friendly

– Too cumbersome if used at dwelling, requires bigger house.

– Have to be on fixed daylight to accumulate 100% energy.

– Has a mechanical machine and makes use of water to generate electrical energy due to this fact requires extra upkeep.

– The solar is just not out there at night time.


Photo voltaic power is free and renewable nevertheless its main value is excessive. However if you happen to consider carefully, the one time value of photo voltaic panels for instance is ample sufficient to save lots of you not less than 40% of your electrical energy consumption per 30 days that can go on for years and years.

LEED, an internationally acknowledged inexperienced constructing system charges a constructing or a home that meets its requirements for being atmosphere pleasant and conserves power. Together with your inexperienced goals, plus utilizing all of the means crucial to save lots of on electrical energy payments and scale back carbon dioxide emissions, it is a waste if you don’t get your house or constructing be LEED licensed. Who is aware of you would possibly get a LEED Platinum ranking in your efforts.
