The photovoltaic modules are a set of photovoltaic cells interconnected in series with the following physical characteristics: they are encapsulated with silicones or other special organic materials that provide a high transmission of radiation, are materials hydrophobic, they allow you to breathe into the cell and does not condense water. Protection by the back of Tedlar or analog material. A tempered glass cover. An anodized aluminum frame that attaches to the module as a whole. Refers to the set of two or more photovoltaic modules photovoltaic panel or array (array in English). The photovoltaic modules that comprise an array can be connected together in series, parallel or mixed form, to obtain the voltage or amperage required by the system. Batteries.A solar street lighting system battery bank is responsible for providing electrical energy during the hours of night operation that has fixture.An important aspect to determine for any battery bank, is the size of the same, i.e., the amount of energy it can store, how much more energy is required to store larger will be the battery bank, to less energy to store lesser will be the size of the Bank. A focus higher power you illuminate one larger area or provide us new levels of lighting, but in turn, will consume a greater amount of energy, which translates to an increase of the size of the battery bank, as well as the power installed in photovoltaic panel.

The batteries are sensitive to working temperature since this directly affects the electrochemical reactions that occur within them. When batteries are subjected to temperatures greater than the environment electrochemical reactions they accelerate and its lifespan decreases, conversely, when the battery is subjected to low temperatures extends the shelf life, but there is a risk of freezing due to the variation of the concentration of the acid possessing a State of charge of the batteryto greater shock, less concentration and greater risk of freezing.The ability of a bacterium is normally specified in ampere-hour along with a reference time such as twenty hours, example suppose that the following have a battery data 200 ampere hour and a reference of 20 hours (200Ah@20hrs). This means that the fully charged battery delivery 10 amps for 20 hours. The manufacturer provides these data. Tempo controller.Solar lights require a tempo controller that controls the State of charging and discharging of the batteries, as well as on and off the luminaire as it is set.The main functions of a tempo controller are: Prevent overcharge of batteries for photovoltaic panel They prevent excessive discharging of the battery by the spotlight, by disconnecting the focus by low battery voltage.

It keeps the battery in its state of maximum possible load. Controls the operation time of the solar light fixture. Serves as the point of interconnection between the photovoltaic panel, battery Bank and the solar luminaire is used the battery voltage to regulate its charge State and disconnect the electrical load if certain level, this type of system low battery voltage used as photo cell photovoltaic panel and turn on the light at dusk, incorporate a timer or electronic timing with which program the hours of operation of the luminaire. Hardware. They are the metal parts that are used to join together and support the system with the metal post components, are special pieces manufactured according to the luminaire to install.
