Technical FAQs 4

Do energy storage products need periodic maintenance?

The requirements for periodic maintenance for energy storage products should be identified by the OEM (IEEE 2010). In settings where predictive analytics maintenance is economical, guidance should also be available from the manufacturer that identifies methodologies for assessing when a product may be approaching a failure mode.

How do I backup my solar monitoring system?

Reliable data backup and storage should be provided. A best practice is for data loggers to store 6 months of data and to backup data to cloud storage. A reliable method to “backhaul” the data is required. Most connect to the internet via DSL, but be aware that many site owners will not allow the solar monitoring system to use the site network.

How do you decide if an energy storage system should be replaced?

Determine criteria to decide whether to repair or replace a component; criteria to decide whether to “cannibalize” a string of modules to source replacement modules or to order new parts; and criteria to decide if an energy storage system with declining energy storage capacity should be replaced.

Why is combining solar and storage a good idea?

Monetizing and combining all the different value propositions of combining solar and storage is an ongoing area of research and business model innovation, and will increase the market for PV and the need for financing. The more interactive nature of battery dispatch (charge/discharge) increases the “operations” part of O&M considerably.
