SRP Solar Rate Plans in 2026: What Homeowners Need to Know Before Going Solar

Updated: May 8, 2026

If you live in SRP territory and plan to go solar in 2026, your rate plan matters as much as your system size, panel quality, and installation design. The rate structure you choose affects how your solar savings work month to month, how much value you get from the power your system sends back to the grid, and whether your home is set up for long-term bill control.

SRP offers two main types of solar rate plans for customers with rooftop solar: demand-based plans and export-based plans. Each works differently. One places more weight on how much electricity you use at one time. The other focuses more on time-of-use pricing and compensation for excess solar energy exported to the grid.

In this guide, we’ll break down:

• The two types of SRP solar rate plans available in 2026
• How demand-based and export-based plans differ
• Which homeowners may benefit most from each option
• What to consider before choosing a plan for your solar system

Choosing the right plan is not a small detail. It is a core part of designing a solar system that performs the way it should.

Understanding SRP Solar Rate Plans in 2026

SRP customers who install solar do not all go on the same rate structure. Instead, SRP offers specific plans for homes with distributed generation, and those plans generally fall into two categories:

• Demand-based solar plans
• Export-based solar plans

Both are built around the reality that solar customers still use the grid. Your system may produce plenty of power during the day, but your home still depends on SRP at night, during cloudy periods, and whenever your household demand exceeds solar production.

That is why the right plan depends on more than annual solar output. It also depends on:

• When your home uses electricity
• How much energy you use during SRP’s on-peak hours
• Whether large appliances run at the same time
• How much excess solar your system exports to the grid
• Whether you have battery storage, an EV, pool equipment, or high summer cooling demand

Bottom line: solar savings in SRP territory are shaped by usage patterns, not just by how many panels you install.

The Two Types of SRP Solar Plans

1. Demand-based solar rate plans

Demand-based plans include a demand charge, which is based on the highest amount of electricity your home pulls from the grid during a defined period. In simple terms, SRP looks not only at how much electricity you use, but also at how much you use at once.

That means a home can have strong solar production and still see higher charges if several large loads run at the same time during key billing windows.

Common examples of high-demand events include:

• Running the air conditioner, oven, and dryer at the same time
• Charging an EV while pool equipment is on
• Heavy cooling use in the late afternoon or early evening
• Using multiple major appliances after solar production drops

For some homeowners, demand-based plans can work well. But they require more attention to how and when loads are used.

Available demand-based options

SRP has historically offered demand-based solar structures tied to time-of-use periods and demand billing. Depending on current SRP availability and enrollment rules, customers may see options such as:

• Solar demand plans with on-peak and off-peak pricing
• Variations that include different seasonal structures
• Plans where demand charges are assessed based on the home’s highest usage during specified weekday peak windows

Because utilities can revise plan names, rates, and enrollment terms, the most important thing is not the label. It is understanding how the plan calculates your bill.

Who demand-based plans may fit

A demand-based plan may be a better fit if:

• Your home’s peak usage is well managed
• You can stagger large appliance use
• You are comfortable adjusting habits during on-peak periods
• Your installer designs the system with SRP demand behavior in mind
• You have battery storage or smart home controls that help reduce grid spikes

Common challenge with demand-based plans

The biggest issue is that many homeowners focus on total energy usage and overlook peak demand. That can lead to surprises. Even efficient homes can trigger higher demand charges if large loads overlap.

Mini-conclusion: Demand-based plans reward control. If your household can manage peak usage well, they may perform solidly. If not, they can reduce expected savings.

2. Export-based solar rate plans

Export-based plans work differently. These plans are generally easier for homeowners to understand because they focus on:

• Time-of-use energy pricing for what you buy from the grid
• A separate export credit rate for excess solar sent back to SRP

Under this structure, your home uses solar power first. If your system generates more than your home needs in that moment, the extra energy is exported to the grid and credited at SRP’s export rate.

This setup makes one thing very clear: self-consumption matters. The more of your solar power you use directly in your home, the more value you typically capture.

Available export-based options

SRP’s export-based solar plans generally include:

• A time-of-use structure with on-peak and off-peak energy pricing
• An export credit for excess solar sent to the grid
• Plan terms that may vary based on current SRP tariff updates and enrollment timing

In practice, this means your savings depend on two separate activities:

1. Reducing the amount of electricity you buy from SRP
2. Earning credit for the solar electricity you export

Those are not valued the same way. That is why solar system sizing and usage timing matter so much.

Who export-based plans may fit

An export-based plan may be a better fit if:

• You want a simpler billing structure than a demand plan
• You prefer to avoid managing demand spikes
• Your home can use a meaningful share of solar production during the day
• You want more predictable behavior from your bill structure
• You are pairing solar with battery storage to keep more energy on site

Common challenge with export-based plans

The main limitation is that exported energy is typically credited at a rate lower than the retail rate you pay for grid electricity. That means oversized systems designed to dump large amounts of power to the grid may not deliver the best financial return.

Mini-conclusion: Export-based plans are often easier to understand, but the value comes from using your solar power in the home, not just exporting as much as possible.

Demand-Based vs. Export-Based: What’s the Difference?

Here’s the simple comparison.

Demand-based plans focus on peak grid usage

With a demand-based plan, your bill is shaped by:

• Total electricity usage
• Time-of-use pricing
• Your highest short-duration demand from the grid during relevant periods

That means one poorly timed high-usage event can have a noticeable impact.

Export-based plans focus on energy flow and timing

With an export-based plan, your bill is shaped by:

• When you buy electricity from the grid
• When your solar system offsets your home’s usage
• How much excess energy do you export
• The export credit rate applied to that excess production

This structure is usually more intuitive for homeowners, comparing solar generation to household consumption.

Quick comparison table

Feature	Demand-Based Plan	Export-Based Plan
Main billing driver	Peak grid demand + energy use	Energy use + solar export credits
Complexity	Higher	Moderate
Best for homeowners who…	Can actively manage large loads	Want simpler solar billing
Main risk	High demand spikes	Lower export value than retail usage offset
Solar design priority	Limit peak grid draw	Maximize self-consumption

What matters most: the best plan is the one that matches how your home actually uses power.

Available SRP Solar Rate Plan Considerations for 2026

While exact plan names, rate amounts, and enrollment details can change, homeowners going solar in 2026 should evaluate SRP options using a practical checklist.

1. Look at when your home uses electricity

This is one of the biggest factors.

Ask:

• Is someone home during the day?
• Do you run cooling heavily in late afternoon?
• Do you charge an EV in the evening?
• Does your family use many appliances at once?

If most of your use happens after solar production falls off, your plan selection becomes more important.

2. Understand your air conditioning load

In Arizona, cooling often drives the bill. A home may look efficient on paper but still create costly demand events during summer afternoons and evenings.

Pay attention to:

• AC tonnage and runtime
• Number of systems
• Thermostat schedules
• Insulation and attic conditions
• Pool pumps and other major summer loads

3. Size the solar system correctly

A larger system is not always better.

With SRP solar plans, proper sizing should consider:

• Annual consumption
• Seasonal usage swings
• Peak timing
• Export value
• Whether battery storage is included

Overbuilding can increase exports without increasing value proportionally. Underbuilding can leave too much on-peak grid use in place.

4. Think about battery storage

Battery storage can improve the economics of solar under either type of plan because it helps reduce dependence on the grid when rates are highest or when solar production is low.

A battery may help you:

• Reduce grid imports during on-peak hours
• Lower exposure to demand spikes
• Store midday solar for evening use
• Increase self-consumption under export-based plans

For some homes, storage is no longer just a backup conversation. It is a rate strategy conversation.

5. Review your lifestyle, not just your utility bill

Two homes with the same annual usage can perform very differently under the same plan.

That is because lifestyle changes the math:

• Work-from-home households often use more daytime power
• Families with kids may create large evening spikes
• EV charging can shift savings significantly
• Pool equipment can add avoidable demand if not scheduled well

Mini-conclusion: Rate plan fit is personal. Your home’s load profile matters more than generic averages.

Which SRP Solar Plan Is Better for Homeowners?

There is no universal best option. The right SRP solar rate plan depends on the home, the system design, and how disciplined the household can be with energy timing.

A demand-based plan may be better if:

• You are comfortable managing appliance timing
• Your home has tools to limit peak demand
• You want to optimize around lower peak grid draw
• Your installer has strong experience modeling SRP demand billing

An export-based plan may be better if:

• You want a more straightforward billing structure
• You do not want demand charges shaping your bill
• Your system is designed around self-consumption
• You want a cleaner link between solar production and bill reduction

In many cases, the real answer comes down to system design

The plan itself is only one side of the equation. The other side is whether your solar provider understands SRP territory well enough to design around:

• Peak usage windows
• Roof layout and production timing
• Appliance loads
• Export behavior
• Future battery integration
• EV charging needs

A system that looks good on a proposal but ignores the rate structure can underperform financially.

Common Mistakes Homeowners Make With SRP Solar Plans

Before choosing a plan, it helps to avoid the most common errors.

Assuming all solar savings work the same way

They do not. SRP plan mechanics are different from utilities that use traditional net metering structures.

Focusing only on panel count

More panels do not automatically mean better savings. The value depends on when power is produced and how it interacts with your plan.

Ignoring demand behavior

This is one of the biggest mistakes on demand-based plans. A few high-usage periods can affect the bill more than expected.

Oversizing for exports

If export compensation is lower than the avoided retail cost of self-used energy, too much exported production may weaken the return on investment.

Choosing a provider without SRP-specific experience

SRP territory is not the place for guesswork. Your installer should understand plan design, production timing, and consumption patterns at a detailed level.

Mini-conclusion: Solar performance is not just about equipment. It is about matching the equipment to the utility rate structure.

How to Choose the Right SRP Solar Rate Plan in 2026

Here’s a practical process homeowners can use.

Step 1: Review your last 12 months of electric usage

Look for:

• Summer peaks
• Seasonal changes
• Evening usage trends
• Large recurring loads

Step 2: Identify major appliances and load timing

List out:

• Air conditioners
• Pool pumps
• EV chargers
• Electric water heaters
• Dryers
• Ovens
• Workshops or detached structures

Step 3: Compare self-consumption vs. export potential

Ask how much of your solar production you are likely to use directly in the home during solar hours.

Step 4: Evaluate whether you can manage peaks

Be honest here. If your household is unlikely to stagger major loads, a demand-based plan may be harder to optimize.

Step 5: Ask for SRP-specific modeling

A quality solar proposal should not stop at annual production. It should explain how the recommended system is expected to behave under SRP’s available solar rate plan options.

Step 6: Consider future upgrades

If you may add any of the following, your ideal plan may change:

• Battery storage
• EV charging
• Home additions
• New AC equipment
• Electrification upgrades

Final Thoughts on SRP Solar Program Rate Plans

Going solar in SRP territory can still be a strong long-term move in 2026, but the rate plan matters. Homeowners need to understand the difference between demand-based and export-based solar plans before choosing a system design or signing a proposal.

Demand-based plans can work well for households that manage peak usage carefully. Export-based plans are often easier to follow and may be a better fit for homeowners focused on self-consumption and simpler billing. In both cases, the best outcome comes from aligning the rate plan with your real usage habits.

If you are considering solar in SRP territory, the next step is simple: review your usage, compare the available plan structures, and work with a provider that knows how to design around SRP’s rules, not just around panel production.
