2. Solar Thermal Technology: A Brief Primer

Solar thermal systems capture the sun’s radiant energy with collectors—typically flat‑plate or evacuated‑tube devices—that heat a fluid (often water or a glycol mixture). The heated fluid then transfers energy to a storage tank or a heat‑exchange network, delivering hot water, space heating, or even driving absorption chillers for cooling.

Key advantages of solar thermal over photovoltaic (PV) electricity include:

1. Higher conversion efficiency for heat – Direct conversion avoids the intermediate step of generating electricity, which can be less efficient for heating applications.
2. Thermal storage compatibility – Large water tanks can store heat for days, smoothing out the intermittency of sunlight.
3. Lower lifecycle cost for high‑temperature needs – Processes that require temperatures above 100 °C are more economically served by solar thermal.

These attributes make solar thermal especially attractive for regions with strong solar insolation and for sectors where heating accounts for a substantial share of energy consumption.
