1 RURAL ELECTRIFICATION.

2 RURAL ELECTRIFICATION: HOUSES VILLAGES DEVELOPING COUNTRIES Electric energy is one of the main means for the development of a rural area. Thanks to electric energy it is possible to make easier an endless series of actions, useful for the basic needs: Lighting; Water pumping, transfer and conditioning for human, agricultural (irrigation) and zootechnic uses; Supply of household appliances and various devices able to improve the quality of life; Supply of telecommunication systems, industrial plants, schools, hospitals, public offices ext.. The use of stand alone systems working through renewable energy (photovoltaic, wind, hydroelectric, biomass) makes the supplying of electric energy in decentralized areas much easier, without using expensive cables or airlines which, anyway, will be never foreseen. THE PROGRAMME OF ENERECO srl KM-F SERIES - STAND ALONE KITS FOR THE ELECTRIFICATION OF ALPINE REFUGES ENERECO srl has developed a series of KITS for alpine refuges, complete with appliances at 12, 24Vdc low voltage (refrigerator, lamps, pumps ext.), which can be easily installed. Because of the naturalistic importance of such sites, through these kits ENERECO srl wanted to avoid the use of gensets granting no pollution and the max respect of the mountain territory. KM-I SERIES - STAND ALONE KITS FOR THE ELECTRIFICATION IN DEVELOPING COUNTRIES Thanks to the deep knowledge of the problems in developing countries, ENERECO srl has developed a series of kits complete with special appliances such as A double class refrigerators, very low consumption lamps, high performance pumps, particular household appliances, innovative conditioning plants ext.. These kits are dimensioned using the photovoltaic and wind technology, with the possibility of inserting further back-up generation systems (endothermic generators, fuel-cell, CATs). KM-CUSTOM SERIES - STAND ALONE KITS FOR THE ELECTRIFICATION OF RURAL AREAS, VILLAGES, SMALL COMMUNITIES ENERECO srl is able to dimension, supply and install stand alone rural electrification systems all over the world. Such systems work through photovoltaic, wind, hydroelectric energy, reaching a power till 1MW, for civil uses (villages, small rural communities), industrial uses (industrial activities in rural areas not connected to the public electric grid), health uses (hospitals and medical dispensaries in developing countries) military uses (electric supply of garrisons, barracks, radio networks).

3 LWP1 PHOTOVOLTAIC LANTERN The LPW1 has been designed to meet your need for a reliable and affordable portable light and for charging mobile phones. GENERAL SPECIFICATIONS There are 4 brightness levels available. The duration of each, after one day charging is as follows: Level Duration hours 2 24 hours 3 12 hours 4 6 hours Attention: the light source is high brightness LED. Do not look at the source directly. The indicator will turn red when there is 1 hour of light remain. The indicator will flash with red light for 30 seconds in case the battery is low. CHARGING OF THE BATTERY To charge the battery of the lantern with the solar light, put the SOLAR MODULE under sunlight and ensure that the solar module is directly exposed to the sun. If the module is partially shaded, it will affect and strongly reduce the power output. If you use the Energy Station in the Southern Hemisphere, the module must face the NORTH. If you use the Energy Station in the Northern Hemisphere, the module must face the SOUTH. Install the module by fixing it properly. The led signal turns red when being charged; it turns green when fully charged. It is normal that the charger gets hot when being charged. The item will be fully charged by solar panel after 10 hours (sunlight peak). Pag. 28 di 76

4 MAINTENANCE Make sure that the product is not exposed to liquids; Clean dust or dirt on the solar module with wet cloth Charge it at least once a month to prolong the battery lifespan The battery must be replaced after a certain number of years of use. This must be done by authorized technicians. SYSTEM SPECIFICATIONS Photovoltaic Module Led Light USB plug Rechargeable battery 1,7 W - 6 V 1 x 1 W To charge mobile phone or other applications Li-ion 2600 mah 3,7 V RECYCLING Do not throw any of the components after discarding. To minimize pollution, please recycle them. All of the components used for manufacturing the system are recyclable. LWP1 PHOTOVOLTAIC LANTERN has been completely designed in Italy. Pag. 29 di 76

7 PHOTOVOLTAIC AND HYBRID KITS FOR THE ELECTRIFICATION OF RURAL AREAS (mountain refugees, homes in developing countries, ext.) In an isolated site, not connected to the public electrical grid, the use of a generating set is not always the best solution. In fact it causes pollution, noise, it can have mechanical problems, you should take care of the removal of filters and oils, the supplying of fossil fuel and spare parts for the maintenance ext. These problems do not exist using a photovoltaic or hybrid system. Moreover, the generating set is a bit cheaper but the functioning and maintenance costs are expensive. On the other hand you can amortize the cost of a photovoltaic or hybrid system within 6-8 years and the system has a life time of years considering only a batteries exchange every 6-8 years. KM SERIES KITS DEVELOPED BY ENERECO SRL ENERECO srl has developed a series of standard KITS for the electrification of isolated areas (mountain refugees, homes in developing countries ext.). KM kits are easy to be installed and they are complete with the various electrical devices such as lamps, refrigerators, freezers, pumps ext. They are divided into 2 types: KM-F Series, using only photovoltaic modules, and KM-I Series, using the hybrid technology (photovoltaic + wind). In the KM kits the pv arrays, the batteries and the electrical load have been calculated for the following periods: OCCASIONAL USE (3 days per week) in periods with solar radiation of less than 4,5kWh/m²/day CONTINUOUS USE, in periods with solar radiation of more than 4,5kWh/m²/day KM-F KITS RANGE Characteristics KM-F 1 KM-F 2 KM-F 3 KM-F 4 KM-F 5 KM-F 6 KM-F 7 Photovoltaic power 18Wp 30W p 50Wp 110Wp 330Wp 350Wp 525Wp Supporting structure no no Head pole Head pole Oz/Vz Oz/Vz Oz/Vz Junction box no no no no JB3/24 JB2/24 JB4/24 Charge regulator SLS6.6 SLS6.6 SLS8.8 SLS8.8 SOL J12 SOL S20 SOL T30 Batteries 12V/15Ah 12V/42Ah 12V/65Ah 12V/100Ah 24V/100Ah 24V/230Ah 24V/600Ah Lamps (*) 2x5W 3x7W 3x11W 5x11W 5x11W 8x11W 10x11 24Vdc refrigerator no no no no 50 lit 150 lit 150 lit 24Vdc freezer no no no no no no 150 lit Inverter 230Vac 50Hz no no no 290VA 470VA 1kVa 2,3kVA+CB( ) Pump or autoclave - 24Vdc no no no ACB61 ACB61 ACB61 ACB61 Other no DC/DC ( ) DC/DC ( ) no Radio TV 14 TV 14 We can develop further KM-F kits according to the customer s demand. (*) In the 12Vdc systems th e lamps will be fluorescent, complete with 12Vdc electronic ballast. In the 24Vdc syste ms the lamps will be type DULUX EL and they will be supplied at 230Vac by the inverter inserted in the kit. ( ) DC/DC converter allows to use a radio device. ( ) The inverter has a bidirectional function and it can be also a battery charger if connected to a diesel generating set.

(1) The wind generator is supplied complete with control system; pole and mechanical fixing system are not included. (2) It is a refrigerator complete with freezer. The first value defines the capacity in litres of the refrigerator, the second one defines the capacity in litres of the freezer. The hybrid kits complete with wind system can be mostly used in sites with average wind characteristic of more than 5 m/sec, where the wind part can produce the energy demanded to be combined to the photovoltaic array. For sites with a smaller wind characteristic we will have to do a proper dimensioning. EXAMPLE OF HYBRID PHOTOVOLTAIC KIT 230VAC/50HZ USES PHOTOVOLTAIC ARRAY 12/24VDC USES WIND GEN.
