Because solar intensity increases as you get closer to the equator, the same solar cell normally can't be equally effective in any given location. The UK firm Quantasol has devised a way of allowing solar cells to be fine-tuned according to their positional latitude, providing a substantial bump in efficiency.
Cheap, off-the-shelf parts and a clever design make Skyline Solar's reflective aluminum troughs a contender in the race to make solar ubiquitous

The next frontier in traditional solar panels is concentrators - devices, usually lenses, that concentrate solar power onto the most expensive part of a solar panel - the silicon. Skyline Solar's "solar trough" design concentrates sunlight without using expensive lenses or complicated robotic armatures for tracking the sun as it crosses the sky.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
