Photovoltaic system and Your Home

Photovoltaic systems can be large scale (such as an industrial plant or a solar community grid). 

Or, PV systems can also be purely for your home. 

You could even have micro PV systems that only operate certain things around the house, such as  garden lights, or security lights.

It’s really easy to see how fun it could be to start thinking creatively about different solar energy plans for your home.

But, it will probably help if you have some idea of what goes into a PV system:

Photovoltaic systems (PV Systems) are comprised of these components:

  •          Solar panels that convert the sun’s rays into usable electricity
  •          A power converter, also called a inverter
  •          Racking system for the solar panels (such as for your roof or a ground mount)
  •          Electrical interconnections
  •          Other mounting gear

A solid set of solar energy plans will include solar panels being installed on your roof

Optional Components

  •          Maximum power point tracker (MPPT)
  •          Battery system and charger
  •          Solar tracker
  •          Energy management software

  •          Solar concentrators/ ground equipment

 Types of Photovoltaic Systems

As stated above, these solar power systems can be very large, or very small. 

It really just depends on your solar energy plans and the context of your situation and power needs.  

Here is a look at some of the main types of PV systems that are used:

Stand Alone PV systems

  •          A standalone (also called an off grid system) is not connected to the main electrical grid. 
  •          Can be large or small

  •          Often a battery storage system is used
  •          In non-portable applications a lead acid battery is normally used
  •          A charge controller is used to avoid over charging the battery
  •          The charge controller is also used to increase the efficiency
  • ·        Power converters are also used (inverter)
  •          Standalone solar systems are used by NASA to operate satellites and space vehicles
  •          Most do it yourself (DIY) solar kits are standalone systems

Grid-connected applications

  •          Grid connected PV systems are connected to the public electricity grid
  •          Feeds energy directly into the grid
  •          Uses a special grid tie converter
  •          Reduces your power bill
  •          You make money by selling any surplus energy to the electric company
  •          Easy to install
  •          No batteries Needed
  •          No power storage loss
  •          Offsets the use of fossil fuels

Photovoltaic System Ecological Benefits

If you are like me, and care a great deal about our eco system, then coming up with solar energy plans for your home is right up your alley. 

By utilizing solar energy as an alternative energy source you will be reducing the world’s dependence on crude oil and coal, among others. 

Here is an overview of the how solar energy systems help you live a more sustainable life:

  •          Solar energy reduces your carbon footprint
  •          Solar energy lowers the human impact on global warming

  •          PV systems lower the pollution in the air, hence increasing your life expectancy
  •          Solar power is an alternative energy that does not produce acid rain or smog
  •          Solar power decreases harmful greenhouse emissions
  •          Solar energy living sets an green example for our kids to follow
