Home Solar Power Systems: A Key Role in the "Doomsday Fortresses" of the Wealthy

The Necessity of Solar Power in the Wealthy's "Doomsday Fortresses"

With the increase in environmental issues and global political instability, the wealthy around the world have begun investing in building "Doomsday Fortresses." For example, Facebook founder Mark Zuckerberg has built a massive estate in Hawaii, including a 5,000-square-foot underground shelter capable of withstanding bombing and maintaining high secrecy. The construction of these estates and bunkers requires not only a huge amount of capital but also a reliable energy supply system to ensure their independent operation in emergencies. Solar power systems have become an ideal solution, providing continuous energy supply, especially in situations where traditional power grids may be compromised.

Calculating the Scale of Solar Power Systems Needed for a "Doomsday Fortress"

To ensure that an estate like Zuckerberg's operates normally under any circumstances, we estimate the required scale of the solar power system based on a daily electricity usage of 1,000 kilowatt-hours (kWh). Based on this assumption, the following calculations can be made:

1. Solar Panel Requirements

   • Calculation Method:
     • Average sunlight duration: Assuming about 5 hours of average sunlight duration in Hawaii.
     • Solar panel efficiency: Modern solar panel efficiency is about 15% to 20%.
     • Power generation requirements: The estate's daily electricity usage is 1,000 kWh.
   • Calculation Process:
     • First, determine the daily power generation requirement: 1,000 kWh.
     • Use solar panel efficiency and sunlight duration to calculate the total power generation required by the solar panels.
     • Total solar panel power generation: Approximately 1,111.11 kW, considering average sunlight duration and solar panel efficiency.

2. Required Solar Panel Area

   • Calculation Method:
     • Output of a single solar panel: The output of a standard solar panel (about 1.6 square meters) is approximately 265 to 300 watts.
     • Total power generation: Based on the calculations in part 1.
   • Calculation Process:
     • Determine the total power generation required.
     • Calculate the number of solar panels needed based on the output of a single solar panel.
     • Then calculate the total area required.
   • Required solar panel area: Approximately 7,407.41 square meters, based on an output of about 150 watts per square meter.

3. Battery Storage System

   • Calculation Method:
     • Storage requirements: Considering nighttime and non-sunlight hours, ensure at least one day's electricity supply.
     • Battery efficiency: Considering that the charge-discharge efficiency of batteries is usually between 80% and 90%.
   • Calculation Process:
     • Calculate the total battery storage requirement based on the daily average electricity usage of 1,000 kWh and battery efficiency.
   • Battery storage system requirement: Approximately 1,176.47 kWh. This is to store at least one day's energy requirements, considering battery charge-discharge efficiency.

4. Use of Inverters

   • Inverters: Convert direct current to alternating current for daily electricity use.
   • Choice of solution: You can choose a centralized large inverter or distributed small inverters.
   • Centralized inverter: Typically more efficient and easier to manage, but if a fault occurs, the entire system is affected.
   • Distributed inverters: One for each room or area, more flexible, but more costly and complex to maintain; however, they can be replaced in the event of a fault.
   • Recommended Solution: For a large estate, considering efficiency and ease of maintenance, a centralized large inverter might be more convenient to manage. It allows centralized management of energy conversion and, in the event of a fault, more centralized and efficient maintenance and repair of the entire system. However, considering the factors of the end of the world, perhaps distributed inverters are more suitable for a closed fortress, requiring only replacement in the event of a fault.

Conclusion

For entertainment purposes only, this article helps us understand that in an independent operating system like a "Doomsday Fortress," solar power not only provides an eco-friendly energy solution but also ensures self-sufficiency in energy in extreme situations. This application demonstrates the importance of solar technology in the modern world, not limited to environmental protection and economic benefits, but also including providing stable energy support for potential emergencies.
