It's time to install solar panels on the facility I guess.

Wonder how the solar panel factories will get power. Wind turbines?

  45% of power in northern Vietnam is hydro

    I assume Vietnam has a nationally connected power grid. Nationally, it has a power mix of 25% hydro and 53% coal.

  There's no reason you can't power solar panel factories with solar panels (once you've bootstrapped the process of course, but that applies to any power source).
  - dsalfdslfdsa 2y ago
    You'd need a lot of land, and also need to put aside a proportion of your production (or profits) to cover those panels as they age.

      A proportion of revenue will going on acquiring power regardless of the source.

      When Europeans can buy 500W+ Trina panels for $150 shipped, something tells me this one-time investment isn't going to be too insurmountable.

        Or like 450W panel for 74€ shipped, for example: https://www.leroymerlin.es/productos/energias-renovables/energia-solar/paneles-solares-fotovoltaicos/panel-solar-risen-tipo-n-450-w-91264212.html https://www.leroymerlin.es/productos/energias-renovables/ene...

Factories are immensely energy-intensive. I doubt it would significantly help/

  Factories have big flat roofs. That means low installation cost for solar panels. And these are nowadays pretty efficient. Not perfect angle or random shadow aren’t business or show stoppers now. Especially in a sunny country.

    Even if you cover a factory's whole roof with solar panels, it can't generate enough electricity to run during working hours. Manufacturing takes ridiculous amounts of energy.

      Depends on what are you manufacturing. 200 watts from square meter roof is doable. 3x3 meter is about right space for a single machine with all the enclosures, tables, etc (in Europe). The average sized machines can be used with single phase allowing 3,6 kW power consumption. Half of it comes from solar panels. Halving power consumption is good imho. This math does not work for steel factory. The math is much better for assembly line type plant where only power tools <1 kW are used.
