1. What should be checked before installing solar panels on the roof?
The color of the tiles The number of panels to install The roof's ability to support the weight of the panels The height of surrounding trees
2. What is the purpose of thermal insulation in a solar water heater?
To reduce the amount of heat transfer fluid To prevent heat loss through conduction and convection To increase the amount of energy produced To change the orientation of the solar panels
3. Why is it essential to manage energy in a solar water heater?
To optimize the use of solar energy To increase the consumption of fossil energy To improve the aesthetic appearance of the system To heat water faster
4. What role does a temperature regulator play in a solar water heater?
It filters the water before it enters the tank It heats the water directly It reduces water pressure It adjusts the water temperature according to sunlight
5. What is the importance of regular maintenance of a solar water heater?
To ensure higher energy consumption To maintain the system's optimal performance To increase electricity production To reduce the size of the tank
6. What is one of the risks to avoid when installing a solar water heater?
Installing the collectors at the wrong orientation Checking pressure levels Using heat transfer fluid Servicing the system
7. What are the risks associated with poor thermal management of a solar water heater?
Overheating of the water System inefficiency and heat losses Reduced lifespan of the tank Filter water
8. What is the role of the transparent cover on a solar collector?
Prevent heat from escaping Filter UV rays Increase absorption of infrared rays Limit thermal losses and promote the greenhouse effect
9. Why must the orientation of the collectors be adapted to the latitude in the Northern Hemisphere?
To maximize sun exposure throughout the year To minimize the impact of clouds To ensure greater resistance to weather conditions To reduce pollution
10. What is the main factor to consider to ensure the efficiency of a solar water heater?
The aesthetics of the collectors The number of tanks used The location, orientation, and maintenance of the collectors The color of the heat transfer fluid
