Positioning matters more than extra sealing when solar lights face rain and snow. Choose a spot with morning and afternoon sun, not just bright daylight. Nearby walls, fences, and evergreen branches can create winter shade. In December, low sunlight may reach areas that summer foliage hides. Keep each panel clear of overhanging leaves, dripping gutters, and roof runoff. A small change in angle can prevent water from sitting on the panel.

I once placed a light beneath a broad branch because the area looked attractive. It collected dripping water for hours after the rain stopped. That was a poor choice. During wet weather, check whether water runs toward the fixture from higher ground. After heavy snow, gently remove buildup with a soft brush. Never chip frozen snow with a hard tool. Inspect tilted panels, loose stakes, cracked covers, and cloudy surfaces every few weeks. Seasonal positioning is not permanent; shadows and weather patterns change. Adjustment may be necessary.
