What is the Solar Electricity Handbook - 2019 edition?

The Solar Electricity handbook - 2019 Edition - is a simple, practical book to using electric solar panels and designing and installing photovoltaic solar PV systems.

What is the electric photovoltaic panel Handbook?

The Handbook is a simple, practical guide to using electric photovoltaic panels. The book is suitable for enthusiastic novices and professionals. Clear examples, diagrams and example projects are provided to demonstrate the true capabilities of these systems.

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).

What is the basic unit of a photovoltaic system?

The basic unit of a photovoltaic system is the photovoltaic cell. Photovoltaic (PV) cells are made of at least two layers of semiconducting material, usually silicon, doped with special additives. One layer has a positive charge, the other negative. Light falling on the cell creates an electric field across the layers, causing electricity to flow.

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 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.
