Match each statement to a paragraph

Paragraph A

Solar water heating systems capture sunlight via collectors, typically flat-plate or evacuated tubes, mounted on roofs. Absorber plates coated black convert rays to heat, warming fluid inside. Passive systems rely on natural convection for circulation. Active ones use pumps for efficiency. Benefits include energy savings. Challenges are initial installation costs. Examples show thermosiphon setups in sunny climates. This harnesses renewable energy for domestic use.

Paragraph B

Heat transfer fluid, often antifreeze in indirect systems, carries warmth to storage tanks via heat exchangers. Direct systems heat water itself, suitable for mild areas. Controllers monitor temperatures, activating pumps as needed. Benefits are reduced utility bills. Challenges include freezing in cold regions. In China, evacuated tubes dominate for high performance. Insulation minimizes losses. Mechanics ensure reliable hot water supply.

Paragraph C

Evacuated tube collectors feature vacuum-sealed glass for better insulation, absorbing diffuse light. Flat-plate ones are simpler, with glazed covers. Integration with existing boilers provides backup. Benefits encompass lower emissions. Challenges are maintenance for leaks. Examples include pool heating in resorts. Sizing depends on household demand. Technology advances efficiency in cloudy conditions.

Paragraph D

Future systems incorporate PV-hybrid designs, generating electricity alongside heat. Smart sensors optimize performance via apps. In developing countries, low-cost DIY versions promote access. Benefits are energy independence. Challenges include aesthetic roof impacts. Global incentives subsidize adoption. Mechanics evolve with materials like selective coatings. Overall, solar heating supports sustainable living.

Decide which paragraph, (A) to (D), has the information given in each statement below. Select (E) if the information is not given in any of the paragraphs.

  1. Flat-plate collectors use black absorbers to convert sunlight into thermal energy.
  2. Indirect systems employ antifreeze fluids to prevent freezing issues.
  3. Passive systems depend on pumps for fluid movement in the setup.
  4. Evacuated tubes excel in insulation due to their vacuum design.
  5. PV-hybrids focus solely on water heating without electricity output.
  6. Controllers regulate pumps based on real-time temperature readings.
  7. Backup integration with boilers ensures supply during low sun periods.
  8. Smart apps are emerging for monitoring and optimizing system efficiency.
  9. Active systems circulate fluid naturally without mechanical aid.
