Working in two shifts in record low temperatures and stormy conditions, installers completed the ground mount array in just 36 days (during a record 60-year storm with 24 inches of snow and 60 mph gusts).

Data Loggers Bring More Light to Remote Medical Clinics

The WE CARE Solar team required a better way to log system performance data and monitor usage patterns to ensure that correctly-sized PV power systems were being implemented in the medical clinics.

Bankable Data and Interoperability Standards

Data quality derives from the combination of accurate instruments plus Data Encoding Standards: one can take highly accurate data samples but if there is no agreement as to what the data means, the data could be considered to be of low quality because of its inability to improve the decision making process.
