80 MEGA WATT
Quantity :2,000 to 3,000 solar panels,
Setting up a 80 MW (megawatt) off-grid solar system in UNHCR camps in East Africa.Below is a breakdown of the key components needed to design and implement an 80MW off-grid solar power system Using an example of 1Mw. You are free to add or adjust.
1. Solar Panels (Photovoltaic 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 monocrystalline and polycrystalline, with monocrystalline being more efficient and often used in large-scale projects.
• Total Capacity: Panels must provide enough energy to meet the daily needs of the system, considering off-grid operation without relying on the grid.
2. Inverters
• 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.
• Number 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-acid, or other advanced battery technologies can be used. Lithium-ion batteries are commonly used for large-scale solar off-grid systems 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 number of panels and battery bank configuration.
5. Mounting Structures
• Function: These are the physical 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 grid.
• Fuses and Circuit Breakers: Protect the system from electrical faults and overloads.

Product : Detachable Container Modules
Specifications:
Sizes: 7.2m X 3.6m, 2.7m Ceiling Height.
9m X 3.6m, 2.7m ceiling height
No walls, windows or doors.
All steel members are to be max thickness you can provide.
Just want complete floor construction, corner blocks and posts, and complete ceiling construction including surrounding beams and joists, ceiling sandwich panels, but no roof materials. Surface to be flat and not ribbed.
Vinyl floor finish to be speckled grey. Frames to be light grey. Ceiling panels matt white (Not high gloss).
Explanation: These 5000 units will be moved around a lot and we feel that sandwich panel walls will move too much (and eventually leak) so we plan to use "caravan" composite walls which are all one piece and so can't move when being dragged onto tray tip trucks and slid off them. Because of the 2.7m ceiling height, we understand delivery of such sized panels will be a problem from India or China and so we will have to have the wall panels manufactured in the USA.
We do not want roof material because the 50mm downpipes which are standard in standard typical modules are too small and so we will have to construct complete conventional very low pitched (1 degree) skillion roofs with gutters along one side on all the modules.
These knocked down +/-5000 modules are to be delivered to Orlando, Florida where they will be assembled and fitted out.
You need to be able to provide structural engineering computations to prove the strength of the perimeter frame of the modules.
Can you provide computations which will be acceptable in the USA?
If not, then we will engage structural engineers in the USA to carry out the work.
If you have any questions, please come back to us immediately.
We are very serious.
Without computations acceptable to local councils, the buildings will not be approved for construction.
In the mean time, I need an indicative price for the +/-5000 modules for the USA very urgently . The final price can be arrived at in the near future but if you want to be considered by the client, you need to respond to us quickly.
