motivation

One of my tasks at SunPower was keeping out module & inverter database current with the latest CEC files, but they were frequently mis-formatted, with duplicates or missing data. I wondered what if this data was already in a database that could enforce structure that could be queried for components even if they’re listed with similar but slightly different names.
