CT ST-1 Solar The CT ST-1 Solar exam tests far more than basic photovoltaic installation. You’ll need to understand electrical systems integration, array positioning calculations, and Connecticut’s specific interconnection rules—areas where many candidates miscalculate. Expect detailed questions on battery chemistry, inverter selection, and fire safety codes that separate experienced installers from those relying on checklist knowledge.
