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
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
