Possible Exam Questions
Q: Is it more cost effective to heat your water by solar means instead of gas or electricity? If so, then why?
A: Yes. You will pay out more for the initial setup of a solar water heater, but will recover that cost in the amount of overall savings.
Q: In winter months, when sunlight is less prevelant, is it still possible to have solar heated water?
A: Yes. Through a gravity system called a "drainback" system, the water flows back into a holding tank inside the building the water is used for.
Q: In case of a natural disaster or a power outage is it still possible for the solar panels to produce energy?
A: Yes. The solar panels collect and store energy in large back up batteries that will then power your electricity needs.
