5. Intro to electricity.
▪ Ampere (Amp) : is the amount of current that flows in a circuit at an electromotive
force (voltage) of one Volt and at a resistance of one Ohm.
kW. Hour = 1000 Watt Hour
▪ Volt : A unit of electrical measurement. One volt will cause a current of one
ampere to flow through a resistance of one ohm.
▪ Watt : The unit of electric power in a circuit. One watt equals one ampere
under an electrical pressure of one volt.
▪ Amp. Hour : A measure current over a period of time. 1 amp being used or generated
for one hour equals 1 Amp. Hour.
▪ Watt Hour : 1 watt produced or consumed for a period of 1 hour.

▪ Positioning of solar panel
▪ Put towards sun :
▪ Tilt Angle (of a Solar Array) :
The angle at which a solar array is set
to face the sun relative to a horizontal
position and is usually adjusted
seasonally due to the changing
declination of the sun.
▪ Shadow effect
