the first is commercial by introducing its products and services to the customer in a very innovative and professional way, so in this rule the company executed a lot of projects at Aqaba for private customers and started getting a common known name at the market.

 

The second rule is to create the local awareness for the society, so JAS introduced very useful lectures at Al-balqa applied university (Aqaba Branch), Jordan phosphate mines company, rosary school and other sectors for the public.

The company was established by full strength of a qualified team of engineers and technicians, so its team is one of the few engineers and technician have the know-how of the systems.

üPhotovoltaic Cells (PV):

The most important component of solar panel which produces electricity is photovoltaic cells. The basic function of photovoltaic cells is to convert sun radiant energy into electricity. The word photovoltaic itself means light energy, photo means light and voltaic means energy. Each photovoltaic cell is packed into modules which are called arrays. These cells produce DC direct current when sun is shining directly over them, produced electricity is then send to building electric system or grid station for next step. PV1

Solar power panels are durable and do not require much maintenance, once in while cleaning of solar cell modules will be it. Average life time of solar power panels are up to 20 to 25 years, which justify the initial cost of solar panel.

JAS will provide Yingli solar modules. Yingli Solar is one of the world’s largest fully vertically integrated PV manufacturers and one of the top ranked manufacturers in the world in this sector and its modules are the best in terms of power output and long term reliability.

üInverters:

A solar inverter, or PV inverter, converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local. It is a critical component in a photovoltaic system, allowing the use of ordinary commercial appliances. Solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.

Grid tied solar inverters

Solar grid-tie inverters are designed to quickly disconnect from the grid if the utility grid goes down. This is an NEC requirement that ensures that in the event of a blackout, the grid tie inverter will shut down to prevent the energy it produces from harming any line workers who are sent to fix the power grid.

Grid-tie inverters that are available on the market today use a number of different technologies. The inverters may use the newer high-frequency transformers, conventional low-frequency transformers, or no transformer. Instead of converting direct current directly to 120 or 240 volts AC, high-frequency transformers employ a computerized multi-step process that involves converting the power to high-frequency AC and then back to DC and then to the final AC output voltage.

Type of Inverters

JAS (Jordanian Alternative Solution) company recommends a highly efficient inverter to maximize energy captured to feed the network, ABB inverters are classified as first class inverters in the world with the second ranking. ABB offers one of widest portfolio of solar inverters ranging from small micro-inverters and three-phase string inverters up to megawatt-sized central inverters. This extensive range of solar inverters is suitable for the smallest residential photovoltaic (PV) systems right up to multi-megawatt PV power plants. The offering is complemented by various monitoring solutions as well as a global service network to maximize the return on your investment. inver1

When it is time for you to specify a solar inverter for your PV project, ABB, as one of the world’s leading power and automation technology companies, has very strong credentials to fulfill your requirements for years to come. This trust should help you to comfortably conclude that ABB is a truly bankable choice in solar inverters.

Performance

-  The high speed and precise Maximum Power Point Tracking (MPPT) algorithm provides real-time power tracking and improved energy harvesting.

-  This transformerless device has two independent MPPTs and efficiency ratings of up to 97.8%.

-  Flat efficiency curves ensure high efficiency at all output levels ensuring consistent and stable performance across the entire input voltage and output power range.

-  The wide input voltage range makes the inverter suitable for low power installations with reduced string size.

üSolar Cables:

Solar cable is the interconnection cable used in photovoltaic power generation. A solar cable interconnects solar panels and other electrical components in the photovoltaic system. Solar cables are designed to be UV resistant and weather resistant. It can be used within a large temperature range and are generally laid outside.

One common factor for most of the photovoltaic power systems is outdoor use, characterized by high temperatures and high UV radiation. Single-core cables with a maximum permissible DC voltage of 1.8 kV and a temperature range from -40°C to +90°C are generally used. A three-core AC cable is used for connection to the grid if a single-phase inverter is used, and a five-core cable is used for three-phase feed-in.

DC connection

Individual modules are connected using cables to form the PV generator. The module cables are connected into a string which leads into the generator junction box, and a main DC cable connects the generator junction box to the inverter. In order to eliminate the risk of ground faults and short circuits, the positive and negative cables, each with double insulation, are laid separately. dc1

 

 

Type of cable

cab3

The photovoltaic conductor HIKRA® C meets the requirements of the German electrical commission (DKE). Because of the resistance to temperature and UV, it is deployed on the DC site for the wiring from solar modules, to the string boxes up to the inverter. Thanks to its good resistance to atmospheric conditions, the cable can be laid outdoor but not underground or in water.
