What is the importance of sizing a solar PV system?

Appropriate system design and component sizing is fundamental requirement for reliable operation, better performance, safety and longevity of solar PV system. The sizing principles for grid connected and stand-alone PV systems are based on different design and functional requirements. Provide supplemental power to facility loads.

How do you calculate the number of photovoltaic modules?

Multiplying the number of modules required per string (C10) by the number of strings in parallel (C11) determines the number of modules to be purchased. The rated module output in watts as stated by the manufacturer. Photovoltaic modules are usually priced in terms of the rated module output ($/watt).

How is a PV array sized for a stand-alone system?

The PV array for stand-alone systems is sized to meet the average daily load during the critical design month. System losses, soiling and higher operating temperatures are factored in estimating array output. The system voltage determines the number of series-connected modules required per source circuit.

Should a PV module be compared to a 50 watt module?

For example, it is far convenient to compare performance, physical size and cost when specifying PV modules that will produce 30 amperes at 12 volts @ specified operating temperature rather than try to compare 50-watt modules that may have different operating points. Inverter is required to convert direct current to alternating current.

What is building integrated photovoltaic (BIPV)?

Building Integrated Photovoltaic (BIPV) is an application where solar PV modules are integrated into the building structures.

How do you calculate the energy output of a photovoltaic array?

The amount of energy produced by the array per day during the worst month is determined by multiplying the selected photovoltaic power output at STC (C5) by the peak sun hours at design tilt. Multiplying the de-rating factor (DF) by the energy output module (C7) establishes an average energy output from one module.
