Photovoltaic energy A tailor-made offering for protection and isolation of photovoltaic systems from ABB The components of photovoltaic systems The effectiveness and quality of a system are measured by the effectiveness and quality of each single component. An essential factor in determining the success of a photovoltaic system is the accurate selection of its components, with particular attention to modules and inverters. It should be recalled that for a photovoltaic system to be considered as a good investment, it needs to continue to operate "in good health" for at least 20 years in bad weather and hot sun. 2 What is commonly called the "BOS" (Balance of System), i.e. protection, control and isolation of electromechanical devices and cables, definitely plays a role in ensuring both an adequate protection of people and of the assets related to the system, and an adequate production of energy over the years. From an economic viewpoint, and even more in comparison with a common electric system, each single component of a photovoltaic system must be chosen above all according to the warranties given by the product and by its manufacturer, because every device must keep its operating features unchanged throughout the useful life of the system and of the related investment. Feed-in Tariff - Italian experience The value of "clean energy" is measured in terms of environmental impact reduction, cost savings and government incentives The current incentive system to encourage the creation of photovoltaic systems is based on the remuneration of the energy produced. In Italy, for example, the rules defining this incentive structure have been laid down by the Italian Ministerial Decree of 19/02/2007, also known as "nuovo conto energia" (new feed-in tariffs) and the resulting resolutions issued by the Autorita per l'Energia Elettrica ed il Gas (the Italian electricity and gas authority) setting forth in detail three important aspects: responsibility in measuring the energy produced, the system of relations with the electricity network provider to connect the system to the public grid, the system of relations with the Gestore dei Servizi Elettrici (Managing Authority of Power Services) to request the feed-in tariffs. These feed-in tariffs are the money value paid for each kWh produced by the system for 20 years, starting from the day of connection to the grid. This value is defined by a table, according to the degree of architectural integration of the system with reference to the building on which it is installed and to the rated power. In Italy, the feed-in tariffs paid for the systems connected to the public grid during 2009 will be reduced by 2% starting from 1st January 2010. The power subject to feed-in tariffs was established at 1200 MW, with a 14-month extension to connect other systems after said limit has been reached. Administrative procedures are divided into 2 different steps: first of all the photovoltaic system must be connected to the public grid through a special connection procedure set forth in the AEEG 99/08 resolution. Once the system has been connected to the grid, there is a 60-day term for submitting the request for the feed-in tariffs to GSE. This can be done by a special online procedure available on the Web site: www. gse.it. Due to the "Feed-in Tariff" incentives and to the growing public awareness of the need to promote the development of "clean" energy sources, photovoltaic systems for electricity generation are becoming increasingly widespread in Italy.

The variety of photovoltaic systems in terms of power, inverter type (with mains-frequency transformer, with high-frequency transformer or with no transformer) and type of public grid connection (single-phase, three-phase, low or medium voltage) requires careful selection of the components by designers and installers. The presence of high direct current voltage values, together with the unique characteristics of photovoltaic systems (i.e. the system can be powered down only by screening the solar panels and the strings generate short-circuit currents with values very close to the currents generated in standard conditions), make the selection of protection, control and isolation devices particularly critical. In line with the new market requirements, ABB developed a complete and reliable 4 range of products specifically dedicated to photovoltaic applications that meets every system engineering need, from the string on direct current side to the alternate current network connection point. The ABB offering includes fuse disconnector, circuit breakers, switch-disconnectors, surge protection devices (SPD), and watertight consumer units and enclosures for outdoor use, all specifically designed for these types of applications. Equipment for the direct current system section Effectiveness and cost-savings: a complete and reliable range of products from ABB experience. Since increasingly higher values tend to be used (to reduce losses), ABB developed specific products to meet the various system engineering needs, reducing the costs for systems up to 500 V and optimizing performance for higher voltage values. S800 PVs are available both in the switch-disconnector version (S800 PV-M) and in the circuit-breaker version (S800 PV-S) and are the most compact circuit breakers in the market for protecting direct current circuits. This line is now complemented by the miniature circuit-breaker S284 UC, Z curve, that can reach 500 V d.c. with sizes up to 16A. All the accessories typically provided with the standard modular products are available: voltmeter shunt trip or undervoltage releases, auxiliary contacts and fault signal contacts. For single string protection in large-sized systems, compact modular fuse disconnectors are provided, capable of housing 10x38mm fuses with voltage up to 1000 V d.c. To guarantee maintenance operators safety, the use of the DC20 fuse disconnector (i.e. that can operate on the circuit only with no load) must be combined with DC21 switchdisconnectors. For string and inverter protection, ABB also developed a range of products dedicated to the complex protection against surges of atmospheric origin on DC side. The OVR PV surge protection devices are specifically targeted at this kind of application, with a Y connection for systems up to 1000 V. The Gemini series IP66 switchboards can be optimally used as string boxes or parallel boxes, i.e. for installation outdoors next to the modules. With its unequalled range, ABB developed a number of "plug & operate" solutions, that is a number of finished, wired and certified switchboards to meet the needs of the most varied types of installations: from the single string for residential applications to the large solar farms. 5 String boxes, 1 string 16 A 500 V Example 1 E 90 PV fuse disconnectors The E 90 PV fuse disconnectors, designed to make voltages of up to 1000 V d.c. (cat. DC-20B) with no load, are ideally suited for photovoltaic systems, where they are used to isolate the single strings and protect them against short circuit. All the ABB string boxes are provided with fuses for photovoltaic plants. OT switch disconnectors The OT Series of high-performance and easily available disconnectors is characterized by high voltage values and compliance with the most advanced international standards, which make these disconnectors ideal in terms of cost and performance for small-sized installations. Europa 8 modules 6 OVR PV All the ABB string boxes are provided with surge protection devices, specifically designed for photovoltaic applications of the OVR PV series. Only a specific product can ensure the proper operation of the cartridge until the end of its useful life, with no risks of short circuit or danger in case of polarity inversion. String boxes, 2 strings 16 A 500 V Example 2 S284 UC-Z miniature circuit-breakers. The range of S280 UC miniature circuit breakers is equipped with permanent magnets on the internal arc chutes that enable the extinction of the electric arc up to 500 V d.c. with Icu=4.5kA, making them ideal for small home photovoltaic systems. Europa series consumer units The Europa series consumer units ensure IP65 protection class and are perfectly suited also for outdoor applications, typical of photovoltaic systems. Europa 12 modules 7 String boxes, 4 strings 40 A 800 V Example 3 S800 PV Available both in switchdisconnector version (S800 PV-M) and in miniature circuit-breaker version (S800 PV-S), they provide high performance in a very small space. Europa 36 modules 8 String boxes, 6 strings 63 A 800 V Example 4 Gemini switchboards The Gemini switchboards enable the installation of parallel boxes outdoors, thanks to the IP66 protection class. The high structural quality ensures their durability over time, even in environments with considerable thermal stress. Tmax PV The range of Tmax disconnectors for photovoltaic systems is characterized by high voltage values obtainable in a compact space.
