This standard for performance criteria applies to all terrestrial photovoltaic power systems (flat plate and concentrators) regardless of size or application. Its principal purpose is to present an overall framework into which all other terrestrial solar photovoltaic power system performance ancillary standards can be developed.

This recommended practice applies to utility-interconnected PV power systems operating in parallel with the utility and utilizing static (solid-state) inverters for the conversion of direct current (dc) to alternating current (ac). (This recommended practice does not apply to systems utilizing rotating inverters.) This recommended practice describes specific recommendations for "small" systems, rated at 10 kW or less, such as may be utilized on individual residences. These recommendations will… read more provide greater standardization for these smaller systems, thereby reducing the engineering and design burden on both the PV system installer and the interconnecting utility. "Intermediate" applications, ranging from over 10 kW up to 500 kW, follow the same general guidelines as small systems. Options to have adjustable setpoints or other custom features may be required by the inter-connecting utility, depending on the impact of the PV system on the portion of the utility system to which it is interconnected. "Large" systems, greater than 500 kW, may combine various standardized features as well as custom requirements, depending on the impact of the PV system on the portion of the utility system to which it is interconnected. A greater degree of custom engineering of the utility interface is to be expected as the size of the PV system grows in relation to utility system capacity read less

Stand-alone photovoltaic (PV) systems provide energy to a load as well as to a battery storage system that powers the load at night or other times when the PV array output is insufficient. This recommended practice provides test methods and procedures for assessing the performance of stand-alone PV systems that include PV modules, charge controller, batteries, and loads. This recommended practice provides testing on a system level that can be performed at a test laboratory or by qualified… read more personnel in the field with the appropriate test equipment. These tests are intended to evaluate the adequacy of the system design (including under worst-case conditions) and performance claims. They require about one month to complete. These tests do not address component or system reliability, quality issues, safety, or compliance to any Codes (e.g., the National Electrical Safety Code(NESC(R)) [B6]2). These tests do not cover PV systems connected to an electric utility. Test results are only relevant to the system tested. If the PV system or load changes in any way, then the tests should be rerun on the modified system. It may be desired to run performance tests on the load(s). Such tests may be found in other documents, for example, Servant and Aigullon [B7] describe how to test a lamp in a photovoltaic system. Such tests, however, are beyond the scope of this recommended practice and may require specialized test equipment and procedures. read less

This recommended practice provides a procedure to size a stand-alone photovoltaic (PV) system. Systems considered in this document consist of PV as the only power source and a battery for energy storage. These systems also commonly employ controls to protect the battery from being over- or undercharged and may employ a power conversion subsystem (inverter or converter). The issues of array utilization, battery-charge efficiency, and system losses are also considered in terms of their effect on… read more system sizing. This recommended practice is applicable to all stand-alone PV systems where PV is the only charging source. This document does not include PV hybrid2 systems or grid-connected systems. This document is normally intended to be used in conjunction with IEEE Std 1013 when the solar/PV array is paired with a lead-acid battery systems.3 This recommended practice does not include the sizing of the system controller, inverter, wiring, or other system components. read less

This guide provides general and specific recommendations on application of step-up and step-down liquid-immersed and dry-type transformers in distributed photovoltaic (DPV) power generation systems for commercial, industrial, and utility systems. The guide focuses mainly on the inverter transformers of the DPV power generation systems that are connected to the inverters supplying ac voltage and current to the primary (LV) winding of the transformer. Some specifics attributed to the auxiliary… read more power transformers in these systems are also discussed. Transformers covered in this guide comply with the relevant requirements defined in the IEEE Std C57.12.00 for liquid-immersed and IEEE Std C57.12.01 for dry-type transformers. read less
