About OSLEOS
For 15 years OSLEOS has delivered power solutions built on reliable equipment and honest engineering.
Who we are
OSLEOS is dedicated to delivering complete solar power solutions using reliable, high-quality equipment. We supply everything required to build safe, efficient and long-lasting systems for homes, businesses, industries and beyond.
We believe solar should be more than an equipment purchase. It should be a properly engineered energy solution, designed around your electricity consumption, operating requirements and financial objectives.
That is why we supply the whole system, from panels and inverters to batteries, protection and voltage stabilizers, and stay with you long after installation.
