ℹPanels typically last 25–30 years with a 25-year output warranty. Microinverters carry a 10–25 year warranty depending on brand. Battery modules degrade faster — expect 10–15 years before capacity drops below 80%. The 25-year savings figure above assumes the panel and inverter run for the full window; budget ~$200–$400 for an inverter swap around year 15 if needed.

What a South Dakota Law Could Look Like

⚡

Based on neighboring states

Utah (1,200W), Maine (600W), and Virginia (1,000W pending) provide the template. A South Dakota law would likely allow 600–1,200W systems to plug into standard household outlets — no permit required.

💸

High rates = strong economics

At South Dakota's avg. $0.117/kWh, a 600W system generating ~880 kWh/year saves roughly $103/year. Payback in as few as 8 years at current rates.

🏠

Renters and condo owners

Plug-in solar requires no permanent installation — just an outlet. This makes it uniquely accessible to renters and condo owners who can't get rooftop solar.
