Test your understanding of solar thermal with 5 practice questions.

Practice Questions

Question 1

In the Hottel–Whillier model for flat-plate solar collectors, which parameter represents the linear heat loss coefficient per unit area?

Question 2

A building requires 200 MJ of thermal energy per day from a solar collector field. If the collector efficiency is 50% and the average daily insolation is 5 kWh/m², what collector area is required?

Question 3

A parabolic trough solar field has an aperture area of 100000 m². With direct normal irradiance of 800 W/m², optical efficiency of 0.75, and thermal efficiency of 0.60, what is the thermal power output in MW?

Question 4

What does 'hybridization' refer to in concentrated solar power (CSP) plants?

Question 5

A thermal energy storage tank uses water to store 150 kWh$_\mathrm{th}$. If the allowable temperature swing is from 45 °C to 90 °C and the specific heat capacity of water is 4.2 kJ/(kg·K), what approximate storage volume is required in cubic meters?
