Solar Energy Explained


1)  WHAT IS SOLAR ENERGY?

Solar power is energy from the sun and without its presence all life on earth would end. Solar energy has been looked upon as a serious source of energy for many years because of the vast amounts of energy that are made freely available, if harnessed by modern technology.

2)  WHAT ARE THE BENEFITS OF USING SOLAR ENERGY?

Solar energy is not only sustainable, it is renewable and this means that we will never run out of it. It is about as natural a source of power as it is possible to generate electricity. The creation of solar energy requires little maintenance. Once the solar panels have been installed and are working at maximum efficiency there is only a small amount of maintenance required each year to ensure they are in working order. They are a silent producer of energy. There is absolutely no noise made from photovoltaic panels as they convert sunlight into usable electricity.

3. WHAT ARE THE DIFFERENT TYPES OF SOLAR SYSTEMS? 

For residential and commercial use we recommend the (hybrid) grid tie installation.

 GRID-TIE

Where the solar system is electronically synchronized to the grid.

Excess produced power will be delivered back to the grid, owners of grid-tie system are classified as “prosumers”

 

Pro

  • Offers unlimited (grid) power when you need it
  • Power during rainy days or malfunctioning of solar system
  • Fullest efficiency and optimal return of investment
  • Near-zero maintenance
  • Excess power can be sold to utility; so all produced power is “put to use” making the investment efficicient.
  • Returns are compared to energy prices which have a tendency to increase over the years; your return will also increase.

Con

  • No protection against brown-outs

 

 

OFF-GRID

Where the solar system is independent with use of batteries to provide limited power during 24 hrs per day

 

Pro

  • Power in remote area
  • Self sufficient and independent

Con

  • Extra equipment (batteries) is costly and requires maintenance and periodical replacement.
  • Not optimal use of produced energy; you will always produce a buffer which you will not utilize.
  • Batteries are complicated, expensive and decrease overall system efficiency

 

 

HYBRID

Where the solar system is (like the grid tie system) electronically linked to the grid.

In addition to the grid tie system there are batteries available for brown-out protection

Basically it is a combination of a grid-tie and a off-grid system.

 

Pro

  • In addition to the advantages mentioned in “grid tie” it also serves as a brown-out protection
  • In addition to the advantages mentioned in “off-grid” you can downscale your number of batteries.

Con

  • Batteries are expensive and require replacement and maintenance
