Pro Tips

  • 01Solar is now cheaper than every fossil fuel for new electricity generation. The debate is over — the question is how fast the transition happens, not whether it will
  • 02Track installed capacity growth rate, not just total capacity. A market doubling every 3 years means today's leaders could be mid-pack by 2030
  • 03The real bottleneck in clean energy isn't technology or cost — it's grid interconnection queues. Projects wait 3-5 years for grid connection in most US markets
  • 04Battery storage economics change the entire solar value proposition. Without storage, solar peaks at 30% grid penetration. With it, there's no ceiling
  • 05Use cost-per-watt comparisons, not total system cost, when evaluating solar quotes or investment opportunities. It's the only apples-to-apples metric
