Solar Introduction (PV) or Solar power

Astrasun - The best choice for your solar needs

How does it work

The photons of light from the sun excite the electrons in the solar cells into a higher state of energy allowing it to act as charge carriers for an electric current. This energy is known as a Direct Current (DC) 12v 24v 36v etc.

what voltage do we need

In order for this energy to drive our appliances we need a higher voltage (drive) and therefore an inverter is used to change the DC current to a 220v Alternating current ( AC). This current is on the same frequency as our grid (ESKOM).

advantage of solar power

In South Africa we are fortunate to have most sun hours per day. According to NASSA statistics Pretoria has an average of 6.04 hours sunlight per day all year long.
Traditional methods

•  Steam Turbines (Coal)
•  Internal Combustion (Generators)
•  Nuclear Power (Radioactive)

Eco friendly methods

•  Wind Turbines
•  Photovoltaic (Solar)
•  Hydro
•  Biomass
Tradition VS New Generation

The energy generated from the solar panels is stored in batteries as a DC current and extracted with an inverter, inverting it to an Ac current.The modern method is direct application of the energy into the grid via new generation inverters

Change is inevitable due to


  • International pressure from Kyoto Protocol

 

  • Population growth demand

 

  • Responsibility to our environment

 

  • Costs

 

  • Margins of price increases

.


  • Availability

 

  • Dependability

 

  • The way forward

 

  • Keeping up with the neighbors

 

  • Increased media attention



How to start


  • Step 1:
    Accept our responsibility to the preservation of the environment.

  • Step 2:
    Changing the way we think and our consumption patterns.

  • Step 3:
    Educate ourselves about alternatives and options.

  • Step 4:
    Design / plan a long term objective with the help of experts in the field.

  • Step 5:
    Implement a turnaround strategy.

  • Step 6:
    Manage and improve alternative system.

  • Step 7:
    Improve consumption patterns.



The benefits of change


  • Sustainable eco-friendly environment

  • Financial returns (long term savings)

  • Assuring long term availability

  • Independence from the municipality or ESKOM

  • Compliance with the Law
