What is PV O&M life cycle?

The PV O&M life cycle begins with planning and system design. The life cycle ends with provision for decommissioning or disposal of the system. The asset life (about 25 years) is considered the performance period even though ownership may change multiple times during that period.

How long do PV modules last?

PV modules are unique in that they carry very long-term performance warranties of 20 or 25 years (very few types of electrical equipment have such long warranties).

Are PV storage systems safe?

Storage systems in PV plus storage settings call for many overlapping safety standards and precautions, particularly those that apply to working on DC wiring, and bring a set of technology-specific new considerations.

Why is battery energy storage important for PV industry?

It will serve as input to PV industry certification and compliance approaches and practices. Combining PV with storage brings additional financial considerations. Battery energy storage can resolve technical barriers to grid integration of PV and increase total penetration and market for PV.

Why is energy availability important in assessing PV systems?

Both energy and availability are necessary metrics for assessing PV systems. If the stakeholders involved in a contract are most interested in energy production, and if the contract holds parties responsible for energy production, then it is crucial that energy losses associated with unavailability and system performance are accounted for.

How much does a PV system cost?

Another estimate approximates O&M of PV systems at $40/kW/year (about 0.5% of initial cost per year for these early systems), about half of which is amortized inverter replacements (Wiser, Barbose, and Peterman 2009).
