With the advancement of the B-wire system, the equation has changed. Solar panels remain a great solution when properly sized, but they are no longer the simple promise of "zero electricity bills" sold for a long time in the market. In this video, I explain what the B-wire system really changes, why it's not simply "taxing the sun," and why the most expensive mistake may be before the panel: in the house design. Because a poorly oriented house, without solar protection, without insulation, and with high air conditioning consumption continues to waste a lot of energy. The panel only tries to compensate for this problem later. A good design, however, reduces demand from the beginning. The thesis is simple: solar energy shouldn't replace design. First, you reduce your home's energy consumption. Then you size the system correctly. In the video, I show why the payback period for solar has changed, how self-consumption has become more important, why batteries are gaining ground, and what the correct technical order should be for those who want to build or renovate efficiently. Before asking "how many panels do I need?", perhaps the right question is: "why does my house need to consume so much energy?"
