The lower summer price is not forever
Salt River Project, called SRP, lowered some prices from May through October 2026. SRP says lower gas and market-power costs made the short cut possible. The regular listed prices return after the October billing cycle. That matters when you look at a solar quote in late summer. A bill from one easy month can make a system look better than it will over a full year. Ask the seller to show the normal rate plan and the temporary rate plan side by side.
Your plan can change the math
SRP has more than one solar price plan. Some plans charge for power by the time of day. Some also have a demand charge. A demand charge looks at a short time when your home pulls a lot of power at once. Running an air conditioner, pool pump, oven, and EV charger together can matter. Solar panels may help in daylight. They may not cover a busy evening. Do not assume more panels erase a demand charge. Ask which exact plan the quote uses and what one high-use time could do to your bill.
Extra solar has its own price
On SRP export plans, extra power sent out from your roof gets a fixed credit. SRP says the current export credit on several plans is 1.87 cents for each kilowatt-hour. That is not the same as using your own solar power in the house. A kilowatt-hour is the small unit on your bill. The simple lesson is to first lower the power you buy when your home needs it. Then look at export credit. An installer should show the solar you use right away, the solar you send out, and the grid power you still buy.
A battery can change the time, not make free power
A battery can save daytime solar power for later. That may help with a hot evening, depending on your plan and home use. It can also keep a few chosen loads on during an outage if the system has the right backup gear. It does not make every part of a bill disappear. It also does not mean your whole home will run. Ask for a written list of what stays on. Ask how the battery will act during SRP's high-cost hours. Then compare the price with a solar-only plan using the same 12 months of bills.
Use your own 12-month pattern
The U.S. Energy Information Administration says electricity bills vary by how and when a home uses power. Your own history is better than a neighbor's bill or a flyer. Download 12 months from your SRP account. Mark the months with the highest use. Note big loads like pool equipment, two air conditioners, electric heat, and EV charging. If a new appliance is coming, tell the installer. A full-service installer should run the plan using your actual use, not only the last low bill.
Simple homeowner checklist
Save 12 months of SRP bills before you get a quote. Ask whether the quote uses the temporary May-to-October price cut or the regular price. Get the exact SRP solar plan name in writing. Ask whether the plan has a demand charge. Ask what you earn for extra solar sent to the grid. Get one quote for solar only and one for solar plus battery. Ask what stays on during an outage. Do not count an old federal homeowner tax credit for a new 2026 project unless a current official source proves it applies.
