Alpine sun is generous yet tricky, with rapid shifts from cloud to crystal clarity and powerful albedo from late snowpack. Model horizons, consider bifacial panels for winter gain, and design mounts that shed rime without inviting wind lift. Track seasonal shadows cast by ridges, lifts, larches, and neighboring roofs.
A good microhydro site begins with patient observation of flow, head, and ecology. Intake screens must protect insects and fry; bypass flows safeguard riffles and pools. Measure spring surge and autumn quiet, place penstocks discreetly, and commit to adaptive management that respects melt timing, sediment pulses, and community water needs.
