SOL4 Tech Specs

SOL4 stands for 4 square meters of mirror surface that capture solar energy.
Our solar concentrators are designed to be built locally to lower costs and increase autonomy.


POWER OUTPUT of thermal heat energy is roughly equal to a standard gas stove, but without fuel cost.


OPTICAL SURFACE, such as normal "bathroom" mirror, will reflect the sun’s light onto the focal point to power the application.


MATERIAL COST if you build with retail steel and mirror prices; wholesale prices, recycling and displacing steel with wood can lower costs by up to half.

W:3m, L:4m, H:2m

FOOTPRINT The SOL4 rotates to follow the sun and requires a 3.5m circular area free from shade
