AI exposure: Solar Thermal Installers and Technicians

Install or repair solar energy systems designed to collect, store, and circulate solar-heated water for residential, commercial or industrial use.

Reading this score

computed

Solar Thermal Installers and Technicians is among the least exposed occupations measured, at 7.0% of weighted task load, rank 847 of 923. 86.5% of this job is work current AI systems cannot produce at all. That is not a statement about skill or value. It is a statement about what these systems can and cannot do.

What holds the line here is embodiment. Across this occupation's 21 tasks it averages 2.71 out of 3, the highest of the five friction dimensions. In plain terms, the work has to happen in physical space. A language model cannot move matter. Until the robotics to do this work is both good enough and cheap enough to deploy widely, capability in software does not reach it.

The most exposed thing this job does is Demonstrate start-up, shut-down, maintenance, diagnostic, and safety procedures to thermal..., at 66.7%. The least is Apply ultraviolet radiation protection to prevent degradation of plumbing, at 0.0%. A gap of 66.7% between two parts of the same job is the reason this index publishes at task level. An occupation-wide number would have hidden both.

Within construction and extraction occupations, this one is more exposed than most. The median across the 61 roles in the group is 5.0%, and only 22 of them score higher than this. Occupational families are not uniform, and the spread inside them is often wider than the gap between them.

What would move this score. Of 21 tasks, 1 are currently banded exposed, 2 assisted and 18 untouched. For that distribution to shift materially would take robotics cheap and reliable enough to deploy at scale, not a better language model. The score is re-computed every quarter against a fresh capability reference, and the change is published rather than quietly applied.

Where the score comes from

judged

Every task is scored through the standardised work activities it maps to. These are this occupation’s averages on the six rubric dimensions. Capability is what AI can do; the other five are what stands in the way.

The four closest scores in the same occupational family, then the four closest anywhere in the index.

Read this carefully. Exposure is not displacement. A high score means current AI systems can produce this work, not that anyone will stop paying a person to do it. Adoption depends on economics, regulation and inertia that this index deliberately does not model. How the score is built.

What this means in practice

Most of this work is not reachable by current systems, so the immediate pressure is on the administrative edges of the role rather than its core: the scheduling, the reporting, the written records. That is where time is recovered.
