Tender description: Supply and Installation of Hybrid Solar System for Yemen
“The ongoing conflict in Yemen has caused significant disruptions to the supply chain and to the overall availability of services. In light of the reduced or even absent provision of public services, communities have adopted various coping strategies, including using alternate water and energy sources, relying on alternate service providers and community-based service delivery initiatives to address the shortfall. UNOPS is undertaking a multi-sectoral engagement aimed at restoring urban services mainly in energy, urban roads, WASH and municipal services in targeted cities in Yemen using an integrated approach. The Yemen Integrated Urban Services Emergency Project is funded by the World Bank, through its fund for the poorest countries, the International Development Association (IDA) and jointly designed between the World Bank and UNOPS”

New clarification added: Regarding Lot 2 , there is a discrepancy between the BOQ and section: System component specification , also discrepancy between the BOQ and specification in returnable bid schedule 4. Which one prevail ?UNOPS REPLY:- Solar Inverter shall be either a group of single-phase inverters connected in parallel with total rating not less than 60kw, for maintenance preference, or three-phase inverter with same rating.- Supplied batteries shall have specification and total capacity as mentioned in the annexes. Connection of the batteries to match the supplied inverters with rated voltage ≥ 48 Vdc.- Regarding cables, as many connection configurations can be provided by suppliers, where the cables sizes will be changed, the cables sizes calculations shall comply the specified standard in the cables specifications IEC 60287. In case of 3*10mm2 and 1*50mm2, are valid if single-phase inverters group is used.

New clarification added: Question: 1- Regarding annex 1 A - Quantity of 4c*16 sq.mm cable in BOQ is 142 meters which is wrong according to table in 8.11.6.3 part the total length will be 392 meters UNOPS REPLY: Cables lengths estimation detailed in the table 8.11.6.3 to be used. ============================================================= Question: - Number of PV modules don’t match number of strings in Junction box They ask for 425 PV modules 320w, 7 Junction Boxes with , 4 strings in each box so the total 28 strings if we put 15 PV modules in each string means 420 PV modules But the required 425 PV modules. We can solve it by using 16 PV modules in 27 string which means 432 PV modules, hence extra cost or by using 330 w, 420 PV modules. UNOPS REPLY: The total number of PV modules is correct as clarified in drawings. Please note that, Array arrangement determined by the inverter input capacity within the determined range in Inverter specifications. ========================================================= Question: - They ask for earthing pit for every single DB (Distribution Board) which means TT earthing system, so earth leakage protection will be mandatory but they didn’t mention it. We can solve it by using RCD for each DB but that means extra cost, or by installing main earthing grid located near the inverter and run earth cables for all DBs UNOPS REPLY: Earthing system requirement is clear according to mentioned standards. Regarding the increase in the cost, it is not a proper time to talk about yet. Therefore, your technical offer shall be clear and detailed.

New clarification added: Question: 1- Regarding annex 2.A, and B UNOPS REPLY: Solar Inverter shall be either a group of single-phase inverters connected in parallel with total rating not less than 60kw, for maintenance preference, or three-phase inverter with same rating. ================================================== Question: - Quantity of batteries 2v, 230 pcs don’t match inverter nominal voltage 48 Vdc It is not recommended to connect more than two strings of batteries in parallelIt is recommended to use 3phase inverter of which voltage Vdc will be higher.UNOPS REPLY: Supplied batteries shall have specification and total capacity as mentioned in the annexes. Connection of the batteries to be match the supplied inverters with rated voltage ≥ 48 Vdc============================================================= Question: - Cables between Inverter and batteries: DC Cable single core 50mm2 While the required inverter is 60kw single phase 48 Vdc the rated DC current will be 1250 amp which requires very very big cable.It is again recommended to use 3phase inverter to solve this mistake. - Cables between Inverter and ACDB: AC Cable 3x10mm2 While the required inverter is 60kw single phase 220 V the rated AC current will be 350 amp which require very big cable. It is again recommended to use 3phase inverter to solve this mistake.UNOPS REPLY: Regarding cables, As many connection configurations can be provided by suppliers, where the cables sizes will be change, the cables sizes calculations shall comply the Specified standard in the cables specifications IEC 60287. In case of 3*10mm2 and 1*50mm2, are valid if single-phase inverters group is used.
