Who owns a PV system?

Asset owner holds title to the PV system or portfolio of systems and may be an individual, a corporation, or, most commonly, a special-purpose corporation, such as a limited liability corporation (LLC), formed just to implement and operate the PV project.

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).

How are topologies determined for PV plus storage systems?

Topologies for PV plus storage systems are typically determined by a combination of regulatory constraints and technical inputs paired with anticipated system behavior and associated system efficiency and cost.

What is PV system performance?

PV system performance is based on how much time is lost when a system is not available and on the performance of the system when it is available. A system may have an availability of 95%, but a performance ratio (weather adjusted) of 100%.

How should a PV system be designed & installed?

PV systems should be designed and installed with such possibilities in mind, and measures should have been incorporated such as two-column racks (rather than post-strut), thick or non-glass covers, rigid backsheets, and through-bolted clamps. The designer should specify PV modules with high ratings for both uplift and down-force pressure.

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.
