What is the main advantage of a maximum power-point tracker (MPPT) charge controller when compared to traditional ones?
Higher efficiency harvesting available power
How are solar modules typically connected together with?
External exposed connectors (MC4)
Blocking diodes within a PV system are connected how?
In Series and forward bias
Wind:
How does the output power vary between cut-in speed and the rated speed on the power curve
Cubically
Which factor in wind, power development, that when changed or altered has the largest effect on turbine output power
Wind velocity
What is the main purpose of a yaw system within a wind turbine
It orientates the rotor blades to directly face the wind
What is the cut-in wind speed for a HAWT?
When the turbine starts generating output power
How would you define an impulse turbine on a micro hydro system
A turbine in which the rotor is driven by water jets impinging on the blades correctly
How would you define an reaction turbine on a micro hydro system
Fully submerged turbine, responsive to water flow
