How does a cost model estimate a photovoltaic system?

This report describes both mathematical derivation and the resulting software for a model to estimate operation and maintenance (O&M) costs related to photovoltaic (PV) systems. The cost model estimates annual cost by adding up many services assigned or calculated for each year.

How do you calculate the cost of a photovoltaic array?

Photovoltaic modules are usually priced in terms of the rated module output ($/watt). Multiplying the number of modules to be purchased (C12) by the nominal rated module output (C13) determines the nominal rated array output. This number will be used to determine the cost of the photovoltaic array.

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 much voltage does a photovoltaic cell produce?

Most photovoltaic solar cells produce a “no load” open circuit voltage of about 0.5 to 0.6 volts when there is no external circuit connected. This output voltage (VOUT) depends very much on the load current (I) demands of the PV cell.

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.

How much PV coverage does a building need?

The extent of PV coverage very much depends on latitude and building orientation. Careful attention must be paid especially to east or west-facing vertical building surfaces that require protection from sometimes very harsh morning or afternoon sun.
