Solar Garden Lights Tested: Winter Performance of 20 UK Models

Solar garden lights underperform in a British winter for reasons that have nothing to do with build quality. In this report Furniture in Fashion explains the energy budget behind every solar light: short days, a low sun angle and frequent cloud shrink the charge a panel can collect at exactly the point when the hours of darkness it must cover are longest. We set out why siting is the decision that matters most, why panel tilt is far more consequential in winter than in summer, and why positions that are sunny in July can sit in shadow all day in December as low sun casts long shadows from fences and walls. We explain how cold reduces effective battery capacity, why charge management features that appear to limit output are what keep a light working, and which maintenance genuinely changes the outcome. A configuration table compares six types of solar light for UK winter use....
