Self-discharge per month - 6% maximum Cycle Life - 1,500 cycles at 20% daily depth of discharge - Polypropylene or similar translucent/transparent case or equivalent - 3 years - High efficiency crystalline silicon modules (mono or Poly crystalline) or equivalent - please specify Voltage at maximum Open circuit Voltage (Minimum power minimum Power rating:) Warranted Number of cells per module - Maximum system voltage: - Guarantee: - 20 Years minimum 1.4 Electrical Fittings, Switchgear and Accessories Electrical switchgear (such as switches, sockets, consumer units, fuses etc.) must be high quality certified to the relevant Kenyan (KS), IEC, British (BS) or equivalent standard. Proof of such certification and origin may be requested. 1.5 Installation Hardware a) Mounting structure: The solar modules shall be mounted on structures fabricated using Iron or Aluminum, strong enough to withstand windstorms of 100km/hr. and be painted to reduce corrosion. Fasteners and other installation accessories (screws, bolts, etc.) should be galvanized or stainless steel. The structures when mounted shall have the modules tilted at an appropriate angle from the horizontal plane and the space between them and the roof/ground shall be at least 6 inches. b) Battery box/rack: The solar batteries (Accumulators) shall be placed in wooden boxes and stacked on racks fabricated from steel and painted to reduce corrosion. c) Cabling: The works shall be carried out in cable routes and therefore the wiring shall be as per standards of existing cable routing or better. Cables and wires shall be of the correct size and quality to carry the minimum requisite current and appropriate voltage drop, laid neatly, adequately fixed, and appropriately terminated. d) Earthing: The array structure of the PhotoVoltaic yard shall be grounded using adequate number of earthing kits. All metal casing / shielding shall be thoroughly grounded to ensure safety of the Solar Photovoltaic power system. Earth resistance readings must be measured by a qualified person and submitted. Resistance values shall conform to IEE regulations. e) Lightning: The system shall be provided with lightning & over voltage protection. The main aim in this protection shall be to reduce the over voltage to a tolerable value before it reaches the PV or other sub system components. The source of over voltage 5

6 can be lightning, atmosphere disturbances etc. Metal oxide variastors shall be provided inside the Array Junction Boxes. In addition suitable MOV s (Metal Oxide Varistors) also shall be provided in the Inverter to protect the inverter from over voltage. f) Installation: The installation will be done in conformity with relevant Kenyan (KS), IEC, British (BS) or equivalent. g) Testing and Commissioning: After the completion of the works, the vendor will perform all necessary tests to ensure the Works comply with the client s requirements and proceed to the systems commissioning and handing over to the client. h) Preferred origin of equipment should be EU and ACP countries System outline Solar Panels Solar Inverter Battery bank Charge Controller Loads/Consumer units 6
