Homemade Solar Concentrator | Solar Box Cooker Improvements

The Homemade Solar Cooker works well on most days, although there are a number of ways to improve it for more marginal days.

The easiest way is to make the reflector as big as the outer box. More reflectors could be made separate to the Homemade Solar Oven. You’ll need a way to hold the position the extra reflectors in place, a few pieces of wire than can be bent to adjust angles might work OK, depending on the wind.

A piece of sheet metal to replace the drip tray, painted black, and lifted off the bottom of the solar oven with cardboard strips will help. The sheet metal will hold more heat.

Making foil covered cardboard pieces the same size as the oven sides placed in the wall spaces will improve the oven, as well
