Solar Collector Efficiency Quiz

What is the best direction for a solar collector to face in order to achieve maximum efficiency?

• North

• East

• South

• West

According to the image, what is the efficiency percentage of a solar collector facing due south?

• 50%

• 70%

• 90%

• 100%

If a solar collector is mounted facing east or west, will it be as efficient as one facing due south?

• Yes, it will be equally efficient.

• No, it will be less efficient but still suitable.

• No, it will not work at all.

• Yes, but only during sunrise or sunset.

Why is a compromise angle of 30° commonly used for the tilt angle of solar collector panels?

• It allows the panel to be perpendicular to the sun's rays at all times.

• It is the angle at which the panel produces the maximum amount of energy.

• It is not practical to alter the tilt angle of the collector panel to be perpendicular to the sun's rays throughout the year.

• It represents the average latitude of the Earth.

During which season is the sun's elevation higher relative to the horizon?

• Spring

• Summer

• Winter

• Autumn

What is the ideal orientation of a solar collector relative to the sun's rays?

• Parallel

• At a fixed angle of 30°

• Perpendicular

• At a variable angle depending on the season

When positioning solar collectors, what should you be aware of to prevent shading?

• The color of the collectors

• Nearby structures, trees, chimneys, and aerials

• The brand of the solar panels

• The angle of the roof

What is a recommended practice to ensure solar collectors are not shaded during different times of the day?

• Installing the collectors at the highest point possible

• Visiting the property at different times of the day to note any shadows

• Using artificial lighting to compensate for shading

• Painting the collectors a reflective color

Before installing a collector panel, what needs to be surveyed?

• The electrical systems of the property

• The strength and condition of the roof

• The plumbing systems within the property

• The interior design of the property

Along with the strength and condition of the roof, what additional factor needs to be considered before mounting the collector panel?

• The color of the roof

• The material of the roof tiles

• Additional forces exerted by the wind

• The angle of the sun
