Last week we discussed at the East Los Angeles Skills Center’s Solar photovoltaic class that the air conditioner is a major contributor to your overall electric bill. Helping your air conditioner run less is the key to dramatically reducing the number of kWh (kilowatt hours) you consume per year. During summer months your attic temperatures has the potential to soar to 150 degrees Installing a solar attic fan can help you remove the heat before it reaches inside your home which has a direct effect on the number of hours your AC will turn to keep you cool.
This is a great example of how a small solar panels can make a great impact on your electric bill by helping you become more energy efficient. It’s always more cost effective to reduce and then produce clean energy and a solar attic fan is a cost effective method to reduce your AC as much as 50%. What do you think? Are solar attic fans a good way to produce negawatts (negawatts)?
