Which inverter is required for a combined PV and storage system?Combined PV and storage system topologies will generally require a bi-directional inverter, either as the primary inverter solution (DC-coupled) or in addition to the unidirectional PV inverters (AC-coupled).
What happens if a micro-inverter is not used in a PV system?If micro-inverters are not used, the PV system will have both AC and DC components. The DC system determines system power capacity and energy production, whereas the inverter and the AC system has the greatest impact on system reliability.
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 much does an inverter monitoring program cost?The cost of the monitoring program can range from minimal (e.g., checking the total electricity generated as reported by the inverter once per year) to exceeding $100,000/yr in high-accuracy monitoring equipment that is watched daily for signs of problems or needed cleaning.
Why should you track energy availability in a PV operation contract?Tracking this availability (or unavailability) provides transparency into the equipment reliability state to all parties involved in an O&M services contract. In most PV operation contracts, energy will be the driving factor of whether the system is operating as expected.
How to maximize PV power consumption?As discussed above, the most common approach is to take advantage of the battery to maximize usage of the power that is being generated by the PV to minimize curtailment during the d
