Solar FAQ — Wichita, Kansas

In Wichita, Kansas, a 5 kW residential solar system produces approximately 7,782 kWh of electricity per year. A 10 kW system produces about 15,564 kWh annually. These estimates use 4.6 kWh/m²/day average solar irradiance and an 80% system performance ratio, accounting for real-world losses from wiring, inverter efficiency, and temperature. Actual output will vary based on your specific roof orientation, shading, and equipment.

Wichita receives an average Global Horizontal Irradiance (GHI) of 4.57 kWh/m²/day. This is 0.07 kWh/m²/day above the US national average of 4.5 kWh/m²/day, placing Wichita near the national average. GHI measures total solar energy incident on a horizontal surface and is the primary indicator of a location's solar resource quality.

Wichita, Kansas receives an average of 5.3 peak sun hours per day. Peak sun hours represent the equivalent number of hours when solar irradiance equals 1,000 W/m² — the standard condition used to rate solar panel output. This means a 1 kW solar panel array in Wichita produces 5.3 kWh on a typical day. Seasonal variation is significant: summer months see peak sun hours 40–60% higher than winter months in most US locations.

Wichita is a average location for solar panels, with 4.57 kWh/m²/day solar irradiance — near the national average. With an estimated payback period of 10.6 years, solar installations in Wichita can be financially attractive, especially given Kansas's electricity rates.

The optimal tilt angle for solar panels in Wichita is approximately 38°, which corresponds to the city's latitude. This angle maximizes annual energy production by ensuring panels receive the most direct sunlight averaged over the year. For maximum winter output, tilt panels at latitude + 15° (53°). For maximum summer output, use latitude − 15° (23°). Fixed south-facing panels at the latitude angle are the standard recommendation for residential systems in Wichita.

A 5 kW solar system in Wichita can save an estimated $988 per year on electricity bills, based on Wichita's average electricity rate of $0.127/kWh. Over a 25-year system lifetime, that represents $24,700 in total savings before accounting for electricity rate increases. After the 30% federal Investment Tax Credit, the net system cost of approximately $10,500 for a 5 kW system yields a payback period of 10.6 years.

For a typical home in Wichita using 1,000 kWh/month, a 5 kW solar system producing 648 kWh/month would offset approximately 65% of a typical household's electricity use. Most residential installations in similar climates range from 5 to 12 kW depending on energy consumption, roof size, and budget. Use SolarScope's Site Studio to get a personalized system size recommendation based on your specific address and energy bills.

Based on local solar irradiance and electricity rates, a 5 kW residential solar system in Wichita has an estimated payback period of 10.6 years. This calculation assumes a net system cost of $10,500 (after the 30% federal ITC) and annual savings of $988. Modern solar panels carry 25-year performance warranties, so systems in Wichita would operate profitably for roughly 14 years after payback. Electricity rate increases over time typically reduce the effective payback period.
