System Components

Photovoltaic module. The “photovoltaic effect” is a physical process through which the photovoltaic cell converts sunlight into electricity. Sunlight is composed of photons. These photons contain certain amounts of energy depending on its wavelength. When photons hit the solar cell and absorbed by it, generate electricity. This happens because the photon energy is transferred to the atom’s electron solar cell (semiconductor material). With this amount of energy now the electron solar cell can be released from its normal position and creates a hole, some of the freed electrons can cross the potential barrier, being driven out of the semiconductor through an external circuit, then there is an electrical current.

Photovoltaic cells can be made with different materials and technologies. Some of these technologies, used in most commercial modules include monocrystalline silicon cells, polycrystalline and amorphous. Using this technology, each cell produces a DC voltage of about 0.5 volts and a current intensity of 1 to 8 A, it requires a significant amount of cells to produce a measurable voltage and power. The photovoltaic cells are interconnected in series in groups ranging from 36 to 72 cells that produce open circuit voltage approximately 20 to 40 volts this set of cells form a photovoltaic module.

The photovoltaic modules are a set of interconnected photovoltaic cells in series with the following physical characteristics:

Are encapsulated with silicone or other special organic materials that give a high transmission of radiation, are hydrophobic materials, to breathe into the cell and water do not condense.

Protection for the back of Tedlar or some similar material.

A tempered glass cover.

An anodized aluminum frame that holds the module as a whole.

The set of two or more modules called photovoltaic array (array in English) or photovoltaic panels. The photovoltaic modules that comprise an arrangement can be connected together in series, parallel or mixed, to obtain the voltage and amperage required by the system.

Batteries. The battery bank of a solar lighting system is responsible for providing electricity during the hours of night operation that has the light. An important aspect to be determined for either battery bank is the same size, ie the amount of energy it can store, the more energy is required to store, the larger will be the bank of batteries, less energy to store the smaller the size of the bank. A more powerful bulb illuminate a larger area or provide us with higher levels of enlightenment, but in turn, will consume more energy, resulting in increased battery bank size, as well as the installed power PV panel. The batteries are sensitive to operating temperature as this directly affects the electrochemical reactions that occur within them. When the batteries are subjected to ambient temperatures above electrochemical reactions are accelerated and shelf life is reduced, however, when the battery is subjected to low temperatures prolongs life, but runs the risk of freezing due to the variation of the concentration of acid that has a battery charge status of the same, the higher the discharge, reduced concentration and increased risk of freezing. The ability of a bacteria is typically specified in ampere-hour with a reference time such as twenty hours a battery example, suppose the following data 200 Amp hour and a reference to 20 hours (200Ah @ 20hrs). This means that a fully charged battery delivers 10 amps for 20 hours. These data are provided by the manufacturer.

Tempo driver. The solar lights require a tempo controller which controls the state of charging and discharging of the batteries and the lamp on and off as scheduled. The main functions of a tempo driver are:

• Prevents overcharging of batteries by the solar panel

• Prevents excessive discharging of the battery and bulb, remove the focus on low battery voltage.

• Maintains the battery at its maximum load state.

• Controls the operation time of the solar light.

Serves as point of interconnection between the solar panel, battery bank and solar light

It uses the voltage of the battery itself to regulate its state of charge and disconnect the electrical charge if the battery voltage down to a certain level, this type of system uses photovoltaic panel as a photo cell and turn on the lamp at dusk, incorporate a timer or electronic timing which is scheduled operating hours of the fixture.

Hardware. Metal parts are used to join and support system components with the metal post are elements manufactured according to the luminaire installed.

Photovoltaic solar energy can be used to provide a source of clean energy, economic, available on the site, for various lighting applications, among which are the lighting and spectacular lighting. The solar lighting systems or solar lighting systems are well designed and adequately provide reliable lighting maintenance free for many years. A solar light basically consists of three elements: the solar panel that converts sunlight into electricity, storage and control system that stores energy and regulates their use and the lighting system depending on the requirements is chosen emitting diode technology light, light, magnetic induction, low sodium vapor pressure.

Assessing the potential of solar street lighting. Lighting for every need there are several factors to consider when evaluating the feasibility of implementing solar lights, factors such as lighting levels, physical characteristics of the installation location, cost comparison between solar lights and conventional lights, are decisive factors when deploy conventional solar technology. Solar street lighting fixtures. The solar street lighting equipment are independent unitary systems designed to operate autonomously to 100%, the solar panel is integrated to the post, normally at its peak, batteries and control system are housed in a cabinet attached to the post. The fixture itself is the whole unit is light and bulb, ballast, reflector – diffuser and housing. Systems are integrated one or two fixtures per pole.

Lighting levels. The solar lighting fixtures provide lighting levels averaged 30 lux, depending on the model, mounting height and luminaire type employees this value may change.

The installation site is suitable for solar lighting. The solar panel should be oriented towards the geographical south of the installation site, free of shadows virtually all day, does the installation area is free of shadows or are there trees, buildings or structures that prevent a good stroke? There are special conditions to take into consideration such as, extreme temperatures, strong winds or marine environments.

Simplified economic analysis. If you need to install lighting systems, autonomous public or solar lights, you should consider the savings that our technology is compared to traditional methods. These savings are reflected not only in the payment of electricity consumption for outdoor lighting concept that is zero, but at the time of making a work of public lighting should take into account costs such as:

Cost of conventional power lines.

Cost of trenching.

Cost for repair of asphalt, concrete, sidewalks, etc..

Cost of transformers, meters, power lines, etc.

Considering these costs as “normal” in conventional public lighting installations, you get the economic benefits to our solar lights not requiring any previous work.

Solar thermal energy is harnessing the sun’s energy to produce heat. As a renewable energy source and free, can be exploited to generate hot water or steam for industrial processes. The potential is enormous, because about 30% of the heat needed for industrial processes require temperatures below 100 º C, which falls within the range that is solar power.

It should set the solar thermal energy needs by type of industry or sector, ACS ejemplo.Calentamiento (hot water). Out of the box can heat 100% of hot water consumption of a hotel during the day at a temperature of 60 degrees Celsius is the usual temperature is usually utilizar.Calentamiento water for industry. May provide all the hot water consumed in the industry, significantly reducing your electricity bill ahorro.La producing a great application of this technology within the industry can provide substantial benefits and can provide much of the process must pass the development of a product.

With high efficiency solar collectors can produce heat at temperatures reaching 150 º C with excellent performance. Among these industrial processes can be found: the generation of steam, washing, drying, sterilization, pasteurization, hot baths of liquid to wash cycles, dyeing, chemical treatment, heating, air drying cycles generation low pressure steam for various uses, etc.Las trash and food industries are working with higher temperatures.

In the case of solar panels the problem is that when more and more solar heat effect, this means that its performance is affected, there is a stagnation of heat and rather than using this energy begins to decrease greatly the efficiency . In addition to these teams do not have axle systems to track the sun and take advantage of more daylight hours. Some teams only have one axis, but this is not enough because the best use of energy is when the sun’s rays fall perpendicularly to the team, so we need dual-axis systems. Instead of concentrating solar equipment as SolarBeam has a consistent performance throughout the day, as they concentrate all the energy of the sun at one focal point, besides not having heat stagnation, has a double axle, allowing further the sun throughout the day and the sun’s rays always fall perpendicularly to the team, all this makes it far superior to other systems.
