Do PV modules need to be updated?

As the work of IEC TC 82 has progressed, a number of new standards for PV components and balance of system equipment have been introduced. Accordingly, the requirements for the safety of PV modules must also be updated to reference these new standards and to fully leverage the benefits that can be achieved by compliance with their requirements.

How much LCOE does a solar PV system have?

Utility PV systems were benchmarked to have an LCOE of approximately 5 cents/kWh in 2020 (Feldman, Ramasamy et al. 2021). To achieve the 2030 SunShot goal, the lifetime economics of PV systems must be improved across multiple dimensions.

What is IEC 61730 & how does it affect a PV module?

However, the IEC 61730 places greater emphasis on safety aspects related to protection against electric shock, as well as fire hazards. It is important to note that PV module components can’t be assessed in isolation from the rest of a PV module.

What is the recommended practice for a solar PV system?

This recommended practice is applicable to all stand-alone PV systems where PV is the only charging source. This recommended practice does not include PV hybrid systems nor grid-connected systems. This recommended practice covers lead-acid batteries only; nickel-cadmium and other battery types are not included.

What is the first international standard governing the safety of PV modules?

The first international standard governing minimum construction requirements for the safety of PV modules was the first edition of IEC 61730, published in 2004.

Where can I find a report on photovoltaic modules?

This report is available at no cost from the National Renewable Energy Laboratory (NREL) at Smith, Brittany L., Michael Woodhouse, Kelsey A. W. Horowitz, Timothy J. Silverman, Jarett Zuboy, and Robert M. Margolis. 2021. Photovoltaic (PV) Module Technologies: 2020 Benchmark Costs and Technology Evolution Framework Results.
