Going Solar at Alamo Colleges!

Solar power is a promising renewable energy source in San Antonio. It can help us power our buildings and keep our lights on, while reducing our dependence on harmful fossil fuels like coal.

How does it work? 

The Sun emits light in the form of photons. These photons travel at the speed of light to reach Earth, which takes about 8 minutes. Upon arrival, the photons are absorbed by solar cell panels made of semiconductor materials that are placed in areas that receive a significant amount of sunlight, like our rooftops. The technology used in these panels allow us to harness the Sun's energy and make it usable. When the photons hit the panels, their cells free energetic electrons, creating a flow of energy, or electricity. This electricity then travels through out electric grid to our buildings and homes.

An egauge system, like the one featured below, helps track how much energy is being generated (green) and compare it to the total amount of energy the building is using (red).

3 Reasons Alamo Colleges is going solar:  

  1. We're being responsible! 
    • It is a clean alternative to other fuels; that does not generate harmful emissions like fossil fuels that negatively impact our atmosphere.
    • The panels operate quietly without disrupting the surrounding natural and built environment.   
     
  2. We're being smart! 
    • The costs of solar has come down substantially within the few years, and in San Antonio there is plenty of free sunshine to use.  
    • Once the panels are installed they require little maintenance. 
  1. We're being a leader!
    • Solar installations are on the rise and the way of the future. Alamo Colleges strives to be a leader and is offering it's students and community an opportunity to learn about solar.
