Solar Savings Fraction
“How can we measure what percentage of the energy to appliances is provided by solar?”
Household appliances automatically become greener when they are supplied by solar energy. But solar energy may not provide all of the energy to a system. So how can we quantify how much energy an appliance receives from solar? Well, we can simply represent this by the Solar Savings Fraction which gives the ratio of solar in the system. A solar fraction of 1.0 means that the entire system used solar energy while one of 0 means that no solar is present. Energy efficiency measures can increase this fraction by reducing the load required from non-renewable resources.
