This is the first part in a new SaveOnEnergy series discussing the ins and outs of different forms of renewable energy. Solar energy has grown in popularity across the country, from massive solar farms to single panels powering residential homes. This is especially true in Texas – which is fifth...

This post will help you to determine the best location for a photovoltaic (PV) system. After you have sized your PV system based upon the calculated the power requirements, you will have to select a location that has maximum sun exposure and limited shading throughout the year. PV arrays can be...

This post will help you to determine how to size a photovoltaic (PV) system. By calculating the power, current, and voltage output required, the size and the number of photovoltaic panels can be estimated. Also, the voltage and current requirements will determine how the solar panels in...

When a PV cell is exposed to sunlight, the photons of the absorbed sunlight dislodge the electrons from the atoms of the cell. The free electrons then move through the cell, creating and filling in holes. It is this movement of electrons and holes that generate electricity. The process of converting...

Most of us are familiar with solar cells because we encounter them every day – in calculators, street lamps, and traffic road signs. If these devices have enough light, they can theoretically work forever. Solar or photovoltaic (PV) cells are made up of many individuals cell stacked together. The cell material is a...
