Monitoring turns data into practical information in useful formats, establishes performance benchmarks and improves managing seasonal or load variations. Remote monitoring alerts technicians when performance drifts or components fail, streamlines operations and management of your solar hot water investment. If you don’t monitor it, you can’t manage it
