The Answer
The Short Answer
Plan the panel location before fixing the light. Shade, season, sun angle, local weather, and nearby artificial light can affect charging or dusk sensors. Use the supplied fixings only where they suit the substrate, protect seals and cable entries, and use a qualified electrician for any model that connects to mains power.
The Full Explanation
Choose the Panel Position
DOE guidance explains that photovoltaic output varies with orientation, tilt, time of year, weather, and shade. In the northern hemisphere, a southerly orientation often improves annual solar collection, but the best position for a small light also depends on its load, panel design, installation constraints, and the maker's instructions.
Mount for the Site and Purpose
Use fixings rated for the wall, fence, ground, or post, and check for hidden services before drilling. Keep beams away from neighbouring windows and roads, maintain the enclosure's intended orientation and seals, and place route or security lighting according to the area that actually needs illumination rather than a generic mounting-height rule.
Commission and Maintain as Directed
Remove packaging controls, select the operating mode, and complete the initial charge exactly as the manual specifies. Test dusk and motion sensors after dark, then revisit the site through the seasons for new shade, dirt, loose fixings, damaged seals, and reduced runtime. Maintenance requirements vary by product.
