SRP solar net metering lets Salt River Project customers with rooftop panels send surplus electricity to the grid and receive credit against the power they draw later. This guide explains how that credit is calculated, what paperwork you need before connecting, and where homeowners commonly lose money. By the end, you will know what to ask your utility and how to check that your bill reflects what your system produces.

How SRP Net Metering Credits Your Solar Output

Your inverter measures how much electricity your panels produce at any moment. When production exceeds what your home is using, the extra flows onto the SRP grid through your meter. When your home needs more power than the panels supply, such as at night, you draw from the grid as usual. The meter tracks both directions, and your bill reflects the net difference over the billing period.

Because exports and imports are netted, a sunny spring month can offset a cloudy winter stretch if your system is sized well. Residential customers on net metering are usually billed on the difference in kilowatt-hours rather than on raw totals. Check your rate schedule to confirm how exports are valued, since SRP has updated its solar rate structures over time.

Steps to Set Up Your System for Net Metering

Before any panels are energized, the utility must approve your interconnection. Most homeowners work through their installer, but you should understand each stage so you can spot delays.

  1. Confirm your home is served by SRP and that your roof and electrical service can support the system size you plan.
  2. Submit an interconnection application with your system design, inverter specifications and single-line diagram.
  3. Wait for written approval before installing the inverter connection or switching on the system.
  4. Have the installation inspected by the local authority having jurisdiction, then request the utility inspection or meter change if required.
  5. Receive confirmation that your bidirectional meter is active, then verify your first bill shows both import and export readings.

Checking Your Bill for Accurate Credits

Many customers assume a solar system automatically cuts their bill to near zero. In practice, your credits depend on your rate plan, your consumption pattern and how well the system matches your usage. Compare your monthly export and import figures against your inverter’s production data for the same period. Large gaps usually point to a meter problem, a shading issue, or a misconfigured inverter, and they are worth raising with SRP promptly.

What to check Where to find it What a problem looks like
Export reading Monthly bill or SRP account portal Zero exports during peak sun months
Import reading Monthly bill Imports unchanged from pre-solar months
Production data Inverter monitoring app Output far below expected for the season

Common Mistakes to Avoid

  • Oversizing the system far beyond your household use, which can leave surplus exports undervalued.
  • Switching on the system before receiving written utility approval.
  • Ignoring a bill that still shows one-way metering after installation.
  • Forgetting that shade from trees or new construction can quietly reduce credits for years.
  • Assuming last year’s rate schedule still applies without reading the current terms.

FAQ

Does SRP net metering pay me cash for extra solar power?

Usually exports offset your consumption on the bill rather than producing a direct cash payment. Check your current rate schedule to see how any surplus credit is handled at the end of a billing cycle.

How long does SRP approval take?

Timelines vary with application volume and whether an inspection or meter change is needed. Ask your installer for the current expected timeline before signing a contract.

Can I add more panels later without a new application?

Usually no. Adding capacity generally requires a new or updated interconnection application, so inform SRP before expanding the system.

Conclusion

SRP solar net metering works by netting the power your panels export against what you import, so your bill reflects the difference over each billing period. Getting approval before energizing, sizing the system to your usage and checking your bill against inverter data will protect your credits. For electrical or interconnection work, consult a licensed professional.
