The idea’s slick, but the real work starts at the inter‑layer contacts. Ten snap‑together layers mean you’ll lose alignment precision, heat dissipation becomes a headache, and the voltage drops across each contact can kill the microgrid’s efficiency. For a weekend hack, it’s probably faster to build a few single‑layer modules—one for the solar panel, one for the battery charger, one for the inverter—and then bolt them together on a simple chassis. If you really want to try the stack, design robust mechanical clamps and keep the current per layer low, otherwise you’ll get a hot, noisy mess. In short, the concept is exciting, but expect a lot of trial‑and‑error if you push it all the way into a microgrid.
