Dear Sir Madam, I"m looking for products with the following specifications: Buyer is interested to receive quotations for the following RFQ - Product Name: Solar Panels Specifications: Type : Batteries , Inverters 80 MEGA WATT Quantity :2,000 to 3,000 solar panels, Setting up a 80 MW (megawatt) off-grsystem in UNHCR camps in East Africa.Below is a breakdown of the key components needed to design and implement an 80MW off-grpower system Using an example of 1Mw. You are free to add or adjust. 1. Solar Panels (tovoltaic Modules) ? Capacity: To generate 1 MW, you would typically need around 2,000 to 3,000 solar panels, depending on the wattage of each panel. o For example, if each panel has a capacity of 300 watts, you will need approximately 3,334 panels (1,000,000 watts 300 watts per panel). ? Panel Type: The most common types are monocrystalpolycrystalh monocrystalg more efficient and often used in large-scale projects. ? Total Capacity: Panels must provh energy to meet the daily needs of the system, consff-grion without relying on the grverters ? DC to AC Inverters: These convert the DC power generated by the solar panels into AC power, which is what most appliances use. ? Inverter Size: For a 1 MW solar system, you will need inverters that can handle 1 MW of power. Typically, this means installing inverters that are slightly larger than the system?s nominal output capacity to handle peak loads. ? of Inverters: A 1 MW solar system may require multiple inverters (e.g., 2 x 500 kW or 4 x 250 kW inverters), depending on the configuration. 3. Battery Storage (Energy Storage System) ? Battery Type: Lithium-ion, lead-acher advanced battery technologies can be used. Lithium-ion batteries are commonly used for large-scale solar off-grs due to their higher energy density and efficiency. ? Battery Size: To store the energy generated by the solar panels for use during night-time or cloudy days, a large battery bank is needed. o For example, if the system needs to run 24 7 with a 5-hour backup requirement, you"d calculate the battery bank size based on your daily energy consumption. o Example: For a 1 MW system that operates 24 hours a day, it would need to generate around 24 MWh daily. Depending on your backup requirements, this could mean needing a battery bank that stores anywhere from 5-10 MWh or more. 4. Charge Controllers ? Function: Charge controllers regulate the charging of batteries to ensure they don?t overcharge or undercharge, prolonging battery life. ? Type: MPPT (Maximum Power Point Tracking) charge controllers are typically used in large solar systems to optimize the energy harvest from the solar panels. ? Sizing: The charge controller should match the system"s capacity. For 1 MW systems, you will need a high-power charge controller, and multiple controllers may be necessary depending on the of panels and battery bank configuration. 5. Mounting Structures ? Function: These are the sical structures that support the solar panels, ensuring they are securely mounted. ? Types: Fixed tilt or tracking mounts. o Fixed Tilt: More common in regions with consistent sunlight. o Tracking Mounts: Move the panels to follow the sun, increasing efficiency, but at a higher initial cost. 6. Cabling and Wiring ? DC Cabling: Connects the solar panels to the inverters and charge controllers. ? AC Cabling: Connects the inverters to the battery bank and loads. ? Sizing: Wiring should be appropriately sized to handle the current and minimize energy loss. In high-power systems, large cables and low-resistance wiring are important. 7. Disconnects and Protection Devices ? DC Disconnects: To safely disconnect the solar panels from the system during maintenance or emergencies. ? AC Disconnects: Disconnects the inverter and other AC components from the electrical load or gres and Circuit Breakers: Protect the system from electrical faults and overloads.
