Optima Engineering has been designing solar photovoltaic (PV) projects since 2007, long before PV became common on the architectural landscape. Optima has also owned and operated its own solar PV system for over 5 years. We have designed over 150MW of solar PV projects, including some 1000V DC systems as well as bipolar arrays. Our experience includes roof mounted, ground mounted, utility scale, and Net Zero Energy buildings. We have also done many studies to prove or disprove the viability of solar PV systems for owners.
