Solar equipment industry has become a considerable marketplace because of various factors. The growth of the market is in a record pace. Sustainable energies in general have witnessed a consequential popularity due to multiple reasons. The approach of renewable energy itself has become a life style for many citizens around the world. It is true that some nations have adopted renewable energies such as solar as they have poor grid capacities. If they do not have suitable installation infrastructure, it is better to adopt SAS (stand-alone systems). Off-grid systems are a great solution for countries like sub- Saharan Africa, which suffer a great lack of electrical access due to poor infrastructure and lack of financial resources. For other nations like European countries implementing renewables or solar in particular is an act of awareness. Governments are aware of the global warming hazardous effect on the globe. Thus, adopting renewables is an attempt to mitigate global warming effect and to conserve energy.
An overview of solar system equipment:
There is a long array of solar system equipment, even though they can be divided into two main categories. The distinguished categories are off grid equipment and on grid systems. However, there is another criterion of differentiation, which is the automation and the degree of intelligence of the device.
Solar equipment suppliers are providing more innovative products to accompany market needs. In the list below, we are going to enumerate the essential products that form a basic solar system.
Of course, the list does not comprise everything. Still it is an attempt to cover more than one aspect and to provide deeper knowledge concerning solar power systems.
Solar panels or solar cells:
Solar panels are the first and essential element that receives or captures solar energy and converts it to direct current charge. This direct current charge has a unit of measurement, which is watt. The panels’ substances of production vary accordingly. Basically, they are made of silicon semi-conductors, which are essential to the conversion phase. The average production of a panel is 250 watt but they range generally from 75 watt to 350 watt as an ultimate capacity.
A collection of panels composes a solar panel system. Each household or industrial facility can decide how much watt they need. Then, a specialized technician can help in the phase of choosing the right panel system. The number of panels installed is decided according to the amount of energy needed.
Essentially, photovoltaic panels and thermal panels are functioning in the same way. The technique is based on the absorption of solar energy and its conversion into other form of needed energies. Simply, a photovoltaic panel converts lights into direct current charge. Whereas, a thermal panel converts radiation into heat.
As mentioned previously, the conversion of energy is the most important step in a solar energy process. Capturing lights through photovoltaic cells needs an element of conversion required for the next step. The next step is the transformation of row energies into practical energy source. Therefore, solar inverters are responsible for this step. Consequently, the direct current charge (produced by the panel) is converted successfully into AC (alternating current). Alternating current is the final form of energy needed for electricity, electronic devices, home appliances, lighting, etc.
Overall, solar inverters are available in two types: central solar inverters and micro solar inverters. Briefly, the central solar inverters is employed in large-scale systems. Thereupon, they are connected always to a solar panel system (many panels altogether). In contrast, micro inverters are functioning in smaller scale, which means to one single panel on the row.
The solar mounting system :
The structural installation of solar panels differs according to the need, size and customer preferences. The racking system of installation depends on extremely precise and exact measurement. Whether it is on the roof of the facility or on the ground, the engineer has to level and adjust the panels carefully and attentively. In order to attain the most effective angle for the best energy absorption. The process is designed to offer most accurate and fastest energy assimilation. For customers who do not like to waste their gardens spaces, they simply will opt for a mounting system on the roof. For others who need great electric energy they have to opt for ground panels for more space. Either ways, solar installers are flexible and can manage both.
In other cases, mainly when the amount of energy needed is limited. Solar equipment companies offer high quality of third generation of PV technologies. This technology is solar transparent windows. Nanotechnology is used to manufacture solar glass windows for domestic, industrial or commercial facilities. To emphasize more the solar glass technology is largely useful for agricultural greenhouses. These solar panels are 70 per cent transparent, so they enable the plants to photosynthesize at the same time they provide needed electrical and heating energy.
Solar Battery Storage System:
The technologies used in storage system of solar energy variate greatly. The evaluation of a battery capacity depends on the duration until it is discharged, proficiency, brand and surely its guarantee period. The surplus of your energy production can be in a great use in times when the cells’ production is really low due to weather inconsistency. Though, until now, the storage system is not that huge no matter how much is the capacity of the storage system, the technologies are advancing. However, for a better efficiency the solution of installing more than one battery for your entire solar system is a good solution to consider.
Solar smart meters
Solar meters or also called pyranometers. Their main mission is to measure solar radiations flow. Furthermore, solar meters can refer to meters, which measure the amount of PV production. The meter offers a real time reading. The data offers exact units of how much a panel is producing. The information provided allows maintaining a good control on the performance of the system.
In addition, solar smart meters offer instant communication between the user and the electrical company responsible for the electricity billing.
Thus, it gives the consumer exact energy data on how much is he producing, and how much is he utilizing. That way the consumer can conserve energy by limiting his consumption.
Other different solar equipment:
In case of on grid system other equipment are involved. The array of solar products is really long. However, we can enumerate certain items such as PV films, back sheets, encapsulation foils, tempered covers, etc. Besides, there are other items of linkage and installation. These items are cables, connectors, copper ribbons, frames, junction box, etc. For smart solar systems, monitoring software, smart meters, smart testers are also needed.
The industry of solar system equipment is growing larger. Forthcoming, we are going to publish shortly an analysis of the solar equipment industrial market share. The rapid growth of the marketplace of equipment and services related to solar energy are the main focus of the next article. Keep following e-electricity magazine for more details.
