Why solar in Saint Petersburg

Under Florida net metering the electricity you use as it is generated and the electricity you export are worth the same thing month to month, both credited at the retail rate. What differs is what happens to a surplus you never use: it is settled at the annual true-up at the utility's lower avoided-cost rate. That single asymmetry is the reason household habits are worth something here, and the changes that capture it cost nothing.

Where the asymmetry actually sits

Florida investor-owned utilities credit excess solar at the retail rate and roll it forward monthly under Rule 25-6.065. Within a month, exporting and self-consuming look much the same in value terms, which is more generous than most states now offer.

The asymmetry appears across the year. Any surplus that survives to the annual true-up is settled at the utility's lower avoided-cost rate, so credit you bank and never spend is worth less than credit you use.

That means the goal is not to avoid exporting, it is to avoid ending the year with a large unused balance. A household that consumes more of its own production over the year converts more of it at full value.

Ask your installer to show the projected month-by-month balance across a year, not just an annual total. Seeing where a surplus builds up tells you whether the proposed system is sized to your household or beyond it.

Changes that cost nothing

Running laundry, dishwashing and any vehicle charging in daylight moves consumption into the production window. It does not require equipment, it can be changed at any time, and on a system already sized close to your usage it raises the share of production you convert at full value.

Pre-cooling the house in the early afternoon while production is strong is the same idea applied to the largest load most Florida homes have. Air conditioning is where the electricity goes, so it is where the opportunity is.

A pool pump is worth looking at specifically if you have one, since it is a large, entirely schedulable load that many households run out of habit rather than by design.

None of this is dramatic on its own. Together, on a well-sized system, it is the difference between finishing the year near balance and finishing it with a surplus that gets settled cheaply.

Sizing, and confirming which rules apply

Systems under the rule are generally sized to no more than 115 percent of annual usage, so your last twelve months of bills are the right starting point for a design rather than a generic profile. Ask every installer to work from your actual bills.

Ask what percentage of your annual usage the proposed system covers, and how the annual true-up was treated in the projection. A model that carries surplus forward at the retail rate indefinitely is not describing the arrangement.

Confirm which utility serves your address first. The bulk of Rule 25-6.065 applies only to Florida investor-owned electric utilities, while municipal utilities and rural electric cooperatives set their own net metering policies and credit rates.

Check the roof before anything is ordered. Panels outlast most coverings, so one within a few years of replacement should be replaced first rather than paying later to remove and reinstall the array. Ask for a condition assessment rather than an age estimate.

Your association cannot say no, and what the federal change means

Florida Statute 163.04 provides that a deed restriction, covenant, declaration or similar binding agreement may not prohibit or have the effect of prohibiting solar collectors or other renewable energy devices from being installed. A property owner may not be denied permission by any entity granted the power to approve, forbid, control or direct alteration of property.

An association retains one specific power: it may determine where on the roof collectors are installed, within an orientation to the south or within 45 degrees east or west of due south, and only if that determination does not impair their effective operation. A proposed relocation that costs meaningful production is therefore worth challenging with a production model rather than an argument.

Apply through the normal process even so. Submitting layout, mounting method, panel and frame colour and conduit routing removes most of the uncertainty a committee is reacting to, and a complete application is approved far more often than one that arrives as a dispute.

On the federal side, the 30 percent Residential Clean Energy Credit under Section 25D expired for property placed in service after December 31, 2025, so a cash or loan purchase now receives no federal credit. Section 48E survives at 30 percent for third-party owners under leases and power purchase agreements, so ask any such provider what they claim and what of that value reaches you, and confirm with a tax advisor.

Incentives & rebates

Net metering: Full retail net metering (FL PSC Rule 25-6.065)

Florida investor-owned utilities offer full-retail net metering under PSC Rule 25-6.065: excess solar is credited at the retail rate and rolled forward monthly, with annual true-up at the utility's lower avoided-cost rate. Systems are generally sized to no more than 115% of annual usage.

Battery + Storage

Why solar + battery in Saint Petersburg

Florida - the Sunshine State - has one of the largest and most active residential solar markets in the U.S., supported by year-round sun, high air-conditioning loads, and full retail net metering. Florida investor-owned utilities still offer full-retail net metering under Florida PSC Rule 25-6.065, which keeps the economics strong for owner-occupied homes. The state also exempts solar equipment from sales tax (FL Statute §212.08(7)(hh)) and shields the added home value from property tax (FL Constitution Art. VII §4(j)). The 30% federal Residential Clean Energy Credit (Section 25D) ended on December 31, 2025 - cash and loan purchases in 2026 no longer receive it, though leased / PPA systems can still indirectly access the surviving 30% commercial Section 48E credit. Hurricane resilience keeps battery storage popular. A typical 8 kW Florida system now pays for itself in roughly 10-13 years for a cash purchase in 2026.

Frequently asked questions

Is it better to use my solar or export it?
Within a month they are close, since excess is credited at the retail rate and rolled forward. Across a year it matters, because any surplus surviving to the annual true-up is settled at the lower avoided-cost rate, so unused credit is worth less.
What free changes improve my return?
Running laundry, dishwashing and vehicle charging in daylight, pre-cooling the house in the early afternoon while production is strong, and scheduling a pool pump deliberately. All shift consumption into the production window at no cost.
What should I ask to see in a projection?
The projected month-by-month balance across a year rather than an annual total, what percentage of your annual usage the system covers, and how the annual true-up was handled. A surplus building up all year is a sign the system is oversized.
Does this apply to every Florida utility?
No. The bulk of Rule 25-6.065 applies only to investor-owned utilities. Municipal utilities and rural electric cooperatives set their own net metering policies and credit rates, so confirm which serves your address before applying any of it.
