How Your Utility Credits Affect Solar Savings
In Avondale, the financial return on your solar investment is heavily influenced by the 'export rate'—the credit you receive for sending unused solar power to the grid. The Roosevelt Irrigation District, like many other Arizona utilities, credits you at a rate lower than the full retail price. For this 2026 estimate, surplus energy is valued at around $0.059 per kWh, while buying power costs closer to $0.156 per kWh. This means the electricity you produce and use at home is worth almost three times as much as the electricity you sell back to the grid. This structure makes adding a battery an attractive option for boosting savings.
Projected Savings
Solar Payback & Savings in Avondale
A solar-only 8.0 kW system is projected to save an Avondale homeowner around $1,412 in the first year, leading to a payback period of approximately 11.8 years. This is a strong financial case on its own.
Adding a battery improves your ability to use every kilowatt-hour you generate. By storing daytime solar power and using it at night, you can increase your annual savings to an estimated $2,125. While the higher upfront cost extends the payback period to around 14.9 years, it also delivers over 50% more savings each year and provides backup power during outages.
