Solar FAQ — Shreveport, Louisiana

In Shreveport, Louisiana, a 5 kW residential solar system produces approximately 7,373 kWh of electricity per year. A 10 kW system produces about 14,746 kWh annually. These estimates use 4.5 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.

Shreveport receives an average Global Horizontal Irradiance (GHI) of 4.54 kWh/m²/day. This is 0.04 kWh/m²/day above the US national average of 4.5 kWh/m²/day, placing Shreveport 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.

Shreveport, Louisiana receives an average of 5.0 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 Shreveport produces 5.0 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.

Shreveport is a average location for solar panels, with 4.54 kWh/m²/day solar irradiance — near the national average. With an estimated payback period of 13.7 years, solar installations in Shreveport can be financially attractive, especially given Louisiana's electricity rates.

The optimal tilt angle for solar panels in Shreveport is approximately 33°, 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° (48°). For maximum summer output, use latitude − 15° (18°). Fixed south-facing panels at the latitude angle are the standard recommendation for residential systems in Shreveport.

A 5 kW solar system in Shreveport can save an estimated $767 per year on electricity bills, based on Shreveport's average electricity rate of $0.104/kWh. Over a 25-year system lifetime, that represents $19,175 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 13.7 years.

For a typical home in Shreveport using 1,000 kWh/month, a 5 kW solar system producing 614 kWh/month would offset approximately 61% 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 Shreveport has an estimated payback period of 13.7 years. This calculation assumes a net system cost of $10,500 (after the 30% federal ITC) and annual savings of $767. Modern solar panels carry 25-year performance warranties, so systems in Shreveport would operate profitably for roughly 11 years after payback. Electricity rate increases over time typically reduce the effective payback period.
