I have divided this list of facts into four categories that might help you to better keep track of things.
- Understanding Our Sun
- Solar History
- Solar Technology
- Solar Metrics
But before you start this list of 12 solar facts, how about a quick trip to the classroom that might help bring all readers up to speed? Here’s a short book list:
- Solar Electricity Handbook – 2014 Edition: A Simple, Practical Guide to Solar Energy – Designing and Installing Photovoltaic Solar Electric Systems, by Michael Boxworth
- Let It Shine: The 6,000-Year History of Solar Energy, by John Perlin
- Photovoltaic Design & Installation For Dummies, by Ryan Mayfield.
Understanding Our Sun
Age: Estimates calculate our sun is 4.6 billion years old, ands will continue burning its hydrogen fuel for another 5 billion years. Will it eventually burn out? Yes, of course — we all learned that in elementary school, right? For those fretting about the lifespan of their PV system’s power source, don’t worry.
Size: The sun is an average-sized star, we find at Cornell’s “Ask An Astronomer.” Here, Christopher Springob tells us, “The biggest stars are more than 100 times as massive as the Sun, and the smallest stars are less than 1/10th as massive as the Sun.”
