Unique off-grid solar lighting products
hei solar light™ is an economically and ecologically very attractive lighting solution. The off-grid solar lighting system meets the highest demands with respect to durability, functionality, quality and design.
hei solar light™ is perfect for new or re-development projects where:
access to the grid is difficult or impossible,
grid connection needs extensive trenching,
restoration of the surface is costly,
underground wiring is close to end of life,
missing right-of-way makes trenching impossible,
as an active contribution and clear sign to renewable energy.
