    INTRODUCTION | SOLAR PANELS

    Welcome to the Panel Pocket Guide: a handy reference guide for solar installers. The pocket guide contains essential information that every solar system designer and installer needs to have on hand when working with panels on rooftops.

    Solar energy comes from the sun and solar panels (also known as PV panels) are used to convert light from the sun which is composed of particles of energy called photons, into electricity that can be used to power electrical loads. In a country like Australia, where there is an abundance of sunlight the uptake of solar panels on residential and commercial properties is currently the largest in the world.

    HOW DO SOLAR PANELS WORK? Solar panels are comprised of several individual solar cells which are composed of layers of silicon, phosphorous (which provides the negative charge) and boron (which provides the positive charge). Solar panels absorb the photons and initiate an electric current. The resulting energy generated from photons

    striking the surface of the solar panel allows

    electrons to be knocked out of their atomic

    orbits and released into the electric field

    generated by the solar cells which then pull

    these free electrons into a directional current.

    This entire process is known as the photovoltaic

    effect.

    An average home has more than enough roof

    area for the necessary number of solar panels

    to produce enough solar electricity to supply all

    of its power needs with excess electricity

    generated going into the main power grid.

    The solar array sends direct current (DC)

    electricity through the charge controller to the

    battery bank. The power is then drawn from the

    battery bank to the inverter, which converts the

    DC current into alternating current (AC) that

    can be used for non-DC appliances. Assisted by

    an inverter, solar panel arrays can be sized to

    meet the most demanding electrical load

    requirements. The AC current can be used to

    power loads in homes and commercial buildings.

    MODULES

    MODULE TYPES There are various module types which are commercially available on the market today. The following is a non-exhaustive snapshot of commonly used modules. 60 Cell vs 72 Cell Module – standard 60 cell modules (referring to standard 6-inch cells) are most commonly used for residential and commercial installations. With dimensions of approximately 1.65m x 1m they are designed to have a suffi ciently large collector area while still being easy to handle. 72 cell modules are most commonly used in large commercial, industrial and utility scale work. Though physically larger (approximately 1.95m x 1m) and more diffi cult to handle in the work environment (ground mount or large roof surfaces) and inherent reduction in balance-of-systems makes them an attractive option for larger jobs. Mono v Poly – the difference between monocrystalline and poly or multicrystalline is the manufacturing process. Monocrystalline cells are formed by drawing up molten silicon starting from a seed crystal of uniform lattice structure silicon. As the silicon boule is drawn it cools with a lattice structure which follows the seed crystal. The single crystal boule is then cut into cells. Polycrystalline cells are usually formed by being pressed in a die or extruded. When this is done the lattice structure is not uniform, hence multicrystalline. Generally,

    monocrystalline cells are more effi cient than multicrystalline cells. N-Type vs P-Type – N-Type and P-Type refer to the type of bulk silicon used to make the cell. To set up an electric fi eld within the cell, a P-N layer needs to be created. This is done by “doping” bulk silicon with elements such as boron for P-type and phosphorus for N-type. Most cells have a P-type bulk layer for the historical reason that they perform better in extra-terrestrial applications. However, as the industry has evolved most PV applications are terrestrial, which is better suited to N-type bulk silicon. N-type bulk silicon cells usually have a price premium associated with them due to differences in the manufacturing process. Half Cell – half cell modules are a relatively new type of module. These modules simply take advantage of reduced resistivity loss by halving the current from each cell. They are basically two parallel modules of series-connected cells put into a single encapsulation. Performance can be boosted by 5-8W per module. A drawback however may be that the leads for these modules are in the centre of the module. Double Glass Modules – double glass modules use a standard cell type encapsulated with glass on both the front and the rear of the module (as opposed to the standard Tedlar backsheet). These modules offer superior strength and as PH
