Solar Energy- Light & Heat
What is solar energy?
Solar energy is the radiant energy produced by the Sun. It is both light and heat.
It, along with secondary solar-powered resources such as wind and wave power, account for the majority of the renewable energy on Earth

Concentrating Photo Voltaic- Up to 50%- Currently about 25%
Solar Thermal◦ - up to 80%, 33% on conversion
Light - Can be 90% Efficient
Efficiency
PV & CPV Panel Efficiency (%): The conversion efficiency of a PV cell is the proportion of sunlight energy that the cell converts to electrical energy.
LIGHT Efficiency: Useful light that makes it into the spaceHeat, Glare, High Contrast can be a problem.

• Good Circadian Rhythm promotes productivity, alertness, and restorative sleep (a healthy immune response cycle)
• Poor Circadian Rhythm contributes to high blood pressure, obesity, diabetes, depression, agitation, and a weaker immune response

Update on the Positive Effects of Light in Humans
Joan E. Roberts, Ph.D., Professor of Chemistry
Light, Sunlight
The right light (Blue wavelengths) on the Retina stimulates the hypothalamus, this results in activity in the:
• pituitary (growth, blood pressure, reproduction),
• pineal (sleep/wake), • adrenal (stress) and • thyroid (metabolism)glands.Daylight does more than make us feel good, sunlight changes
wavelengths from sunrise to sunset setting our rhythm.
