Lena is a contract PV system designer who specializes in battery-based systems. She was inspired to take leave from her high school teaching career to explore the world of renewable energy in 2005. She began her renewable energy career with Solar Energy International (SEI) taking classes, helping construct their PV Lab Yard, and eventually teaching PV classes around the country and on-line. She has written numerous articles for Home Power Magazine, worked as an electrician in Crested Butte and for several solar installers, and is grateful to now own her own business. In addition to her work at Nunatak, she also finds time to design systems across the country from small residential to megawatt sized solar farms with SEIPS, as well as help develop curriculum for a solar training center in Haiti with Remote Energy.
