Pag. 1 of 10 PHOTOVOLTAICS STREET LAMPS FOR DECORATIVE AND PUBLIC LIGHTING GENERAL FEATURES To plan a well working street lighting system with photovoltaic power supply means to consider some basic elements such as: BUDGET. The whole system must be both economical and able to compete with traditional solutions connected to the electricity network (not always at hand). AESTHETIC APPEARANCE. The different components of the street lamp will not be too heavy from an aesthetic point of view. Photovoltaic modules must not be too bulky; fixing structures or poles must not be poorly built and assembled and should not result unsightly; accumulators must not be too bulky and difficult to combine with other elements; control units must not be too large and should not be mechanically connected to the fixing structures. PERFORMANCES. The different components must be connected in a very careful way in order to obtain the best possible performance and to reduce the energy loss. CORRECT ENERGY AND WORKING MANAGEMENT. In order to reduce losses, that in such a system may be fatal, an integrated control device is necessary. This has to be able to: - manage the battery charge with the best possible performance; - optimize the use of the energy stored in the battery according to: kind of photovoltaic field, location, electrical load of the lamp, day of the year; - support different timetables with seasonal variation of the electrical load required: these have to be synchronised with both weather factors (like temperature and insolation) and astronomic factors (like the number of light hours per day); - support a data logger capable of storing at least 15 days of data and - support a local or remote user interface (serial in/out) that allows the access to the on-line or logger data in order to control all the parameters both of installation and of management. For all these reasons ENERECO srl has developed a series of photovoltaic kits for decorative and public lighting.

Example: ballast lamp NAV70 high pressure sodium of 70W: ALX01/HS-70 COMPATIBLE LAMPS Low pressure sodium 18-26-36-55W; high pressure sodium 50-70W; halide vapour 35-50-70W; fluorescent (either compact or linear) from 18W to 80W. A suitable ballast will be provided according to the lamp type. LIGHT DIMMER CONTROL 4 levels for high and low pressure sodium lamps: 100% - 80% - 60% - 40%. For halide vapours lamps the brightness value must not be inferior to 80%. If less the light colour will tend towards a green gradation. For dimmerable fluorescent lamps, the brightness reduction (and its relative energy consumption) can be up to 20%. This option allows a battery energy saving according to the general conditions (time, season, type of installation).

Pag. 7 of 10 OPTIONALS ENERECO srl has completed the control and managing unit STL01 with some OPTIONALS that allow the improvement of the performances: STANDARD HOUR RECEIVER: “RX77” FOR DCF77 – “RXTDF” FOR TDF According to the location, it is possible to use some standards for the synchronising of the digital clock included in the STL01 unit. The DCF77 standard allows an automatic update of hour and date according to the radio signal emitted by the atomic clock of MAINFLINGEN (D), while the TDF is a synchronisation radio signal coming from ALLOUIS (F). Thanks to this receiver both the night lighting timetable and the data logger records are precisely synchronised, also during the solar hour/summer-time change FEATURES COMPARISON FEATURE DCF77 TDF Location of time transmitter Mainflingen (D), near Frankfurt Allouis (F), 150 km South of Paris Transmission frequency 77.5 kHz 162 kHz Transmitter type Dedicated time transmitter Radio transmitter with additional time signal Modulation type Amplitude modulation Phase modulation Range (official) 2000 km 3500 km Operator PTB(¹) LPTF (²) ENERECO srl can use other synchronisation standards for those countries not included in the DCF77 and TDF range limits.

Pag. 8 of 10 RADIO MODEM XTR-434 In order to make the check of the data logger easier and to read the STL01 data on-line, ENERECO srl provides a radio modem that allows the connection to the STL01 unit. It is possible to have access to the data regarding the photovoltaic street lamp system using two XTR-434 devices. One of them will be connected to the STL01 unit and the other one will be connected to a laptop to be placed within a range of 50 or 100mt, depending on the place where the system has to be installed - countryside or city centre. PROXIMITY SENSOR MS20 (ONLY FOR FLUORESCENT LAMP SYSTEMS) The possibility to lower the lamp brightness of a 20% is essential in cases in which compact or tubolar fluorescent lamps with white light are needed or in other occasions such as for decorative street lamps in parks, pavements and seafronts. Actually, the MS20 device can avoid the energy waste of the photovoltaic street lamp system by making the lamp work at the best of its capacity when there is someone passing by while reduces its capacity to 20% if it does not detect any presence within the range of 12 metres. FEATUREA VALUE Time control 1s – 5m Sensor range 12m/2m/130° Working temperature -25°C +70°C Dimensions 100x77x97mm REMOTE CONTROL TERMINAL UNIT The TER15 terminal unit allows to communicate with the STL01 unit without the use of a laptop. ENERECO srl developed this terminal unit to meet the needs of the installers who find the use of a laptop during the installation difficult and bulky. The TER15 terminal unit - connected to the STL01 serial port - makes possible to display the photovoltaic street lamp working. It also shows fundamental electric data such as: battery tension, current produced by the photovoltaic panels, battery SOC and current used by the street lamp. Moreover, it is possible to force the lighting of the street lamp and to download the last data logger records so to display them on your computer sit comfortably in your office. FEATURES VALUES TX current 28mA Stand by 100nA Frequency 433.92MHz TX out power 10dBm Max speed 100Kbps File Ref.: lampioneSTL-ing2.doc Rev. 00 of 06.2005 TTEECCHHNNIICCAALL SSPPEECCIIFFIICCAATTIIOONNSS According to the law, ENERECO srl has all rights reserved and forbid the assignment of this document without its permission.

Pag. 9 of 10 USER INTERFACE SOFTWARE DATALINK 1.0 Thanks to the RS232 serial port of the STL control unit it is possible to use the DATALINK software that allows to display the street lamp working. The software can download the functioning records and start up the night lighting timetables. As you can see from the pictures DATALINK is extremely easy to use. The first picture shows the SYNOPTIC TABLE. It display all the on-line data about the functioning and allows to force the street lamp lighting also during the day in order to check the cabling after the installation. The synoptic table allows also to check if date and hour are correct and synchronised with the DCF atomic clock or others and if the battery has reached the maximum and minimum charge. Another essential value shown in this table is the battery SOC that is the battery State Of Charge in percentage. Through this value the installer can check if the system is well-balanced just a few days after the installation. The second picture shows the DATA LOGGER. It contains up to 1000 records that refers to the street lamp working of the last 10 days. The data logger stores not only the working data, but also all the STL01 functions -both activated and deactivated. The third picture shows the NIGHT LIGHTING TIMETABLES to be set. Through a series of sliders it is possible to set the suitable kind of lamp functioning (100%, 80%, 60% or 40%) with intervals of 15 minutes. This procedure allows to save a lot of energy by storing it in the battery in periods when there are more dark hours (winter and spring) and the daily insolation coefficient is low.
