What affects solar savings in Indiana?

Every homeowner's solar savings are different. In Indiana, the key variables are:

  • Electricity rate (14¢/kWh): Indiana's electricity rate is near the national average. Combined with sun hours and system size, this gives a typical homeowner a solid case for solar investment.
  • Peak sun hours (4.5 hrs/day): Indiana's sun hours are below the national average. This is offset by choosing an appropriately-sized system and optimising roof orientation. South-facing roofs at 20–30° pitch perform best.
  • System size (9kW typical): The right size depends on your electricity bill. A $150/month bill typically requires a 6–8kW system to offset 80–100%. Use our System Size Calculator to find your exact target.
  • Roof type and orientation: South-facing roofs at 30° pitch are ideal. West-facing roofs produce 15–20% less but may generate more electricity during peak-price afternoon hours, improving time-of-use savings.
