A homeowner in Barbados installs a photovoltaic (PV) panel system on a south-facing roof. What is the PRIMARY reason south-facing orientation is recommended in the Caribbean?

Q: How do I try a free CXC Building Technology question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CXC CSEC Building Technology bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CXC Building Technology students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Building Technology questions aligned to the CXC CSEC syllabus?

Every question is written against the published CXC CSEC Building Technology syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CXC past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

A homeowner in Barbados installs a photovoltaic (PV) panel system on a south-facing roof. What is the PRIMARY reason south-facing orientation is recommended in the Caribbean?

Accepted Answer

South-facing roofs receive maximum solar radiation in the Northern Hemisphere — The Caribbean lies in the Northern Hemisphere, where the sun arcs across the southern sky; south-facing surfaces therefore receive the greatest annual solar irradiation, maximising PV output. Trade winds are not relevant to PV panel orientation. Reducing urban heat island effect relates to roofing materials and vegetation, not panel orientation. No universal Caribbean building code mandates south-facing panels specifically for all dwellings.

Answer

South-facing roofs reduce the urban heat island effect more effectively

Answer

South-facing roofs receive maximum solar radiation in the Northern Hemisphere

Answer

South-facing roofs are required by Caribbean building codes for all dwellings

Answer

South-facing roofs receive the most prevailing trade winds
