St. Petersburg's price band
St. Petersburg is cheaper than 94% of the 195 US metros we price for solar panel work.
An 8 kW system with standard panels is $16,250–$25,600 installed in St. Petersburg, about $2,500 per kW at the typical price. A 6 kW system runs $12,750–$20,050 and a 10 kW system $19,700–$31,050. Premium panels add 10–25%.
St. Petersburg is a mid-size solar market. Florida averages about 5.5 peak sun hours a day in NREL data (the US average is about 5). Florida's four investor-owned utilities must offer net metering at the full retail rate; extra credits roll forward month to month and are paid out once a year at the much lower avoided-cost rate. Florida exempts solar from the 6% state sales tax and keeps the added home value off your property tax bill. Duke Energy Florida handles the hookup.
Prices are before incentives. The federal homeowner credit is gone for 2026 installs (it ended for expenditures after December 31, 2025), so any help now comes from your state, your utility or a lease company's own business credit.

Prices cover the St. Petersburg metro and assume a pitched shingle roof in good shape. Older roofs in Midtown & Childs Park more often need repair first.
Solar panel prices across St. Petersburg
The panels cost the same across St. Petersburg; the roofs do not. Flat and older roofs in Downtown St. Pete & the EDGE District push labor up, and big simple roofs in Clearwater & Dunedin keep it down.
Downtown St. Pete & the EDGE District
- 8 kW installed
- $17,250–$27,650 installed
- Typical job
- $13,500–$33,550 / 6–10 kW system
Flat roofs, older buildings and little street parking. Arrays here often need tilt racking or weighted mounts, fire-code walkways cut the panel count, and permit reviews take longer.
Midtown & Childs Park
- 8 kW installed
- $16,750–$26,600 installed
- Typical job
- $13,150–$32,300 / 6–10 kW system
Older homes with character roofs and 100-amp panels. Ask early whether the roof has 10 years of life left and whether the job needs a panel upgrade.
Pinellas Park & Largo
- 8 kW installed
- $16,250–$25,600 installed
- Typical job
- $12,750–$31,050 / 6–10 kW system

Clearwater & Dunedin
- 8 kW installed
- $15,950–$25,600 installed
- Typical job
- $12,500–$31,050 / 6–10 kW system

Real solar jobs in St. Petersburg
Here's what common solar panel jobs cost in St. Petersburg in 2026, installed, before incentives.
Smaller home: 6 kW, standard panels
About 26 kWh on an average day at Florida's sun levels. Smaller systems cost more per kW, about $2,600 here against $2,500 for 8 kW.
Typical home: 8 kW, standard panels
About 35 kWh a day and 12,800 kWh a year. $19,800 is the typical St. Petersburg price for a pitched shingle roof in good shape.
Solar plus a Powerwall 3
An 8 kW system with a 13.5 kWh battery for outages and evening use. Doing both in one job shares the crew, the permit and the utility paperwork.
Big home or EV owner: 10 kW, premium panels
Premium panels make more power per square foot, which helps on small or shaded roofs. Standard panels at 10 kW are $19,700–$31,050.
Re-roof with solar already on it
Taking about 20 panels off and putting them back after the roofers leave, on top of the roof itself. If your roof has less than 10 years left, replace it before solar goes on.
How much do solar panels cost in St. Petersburg?
$16,250–$25,600 installed, with $19,800 the typical St. Petersburg price for 8 kW. Only about a third of that is hardware (panels, inverter, racking). The rest is sales, design, permits, labor and profit, and that is the part that changes from one St. Petersburg installer to the next.
There is no federal credit to take off these numbers any more. What still cuts the bill in St. Petersburg is a second or third quote, the right system size for your actual use, and any state or utility program. Figures re-verified against 42 sources in November 2026.
Solar prices in St. Petersburg (2026): the lines on a quote
An 8 kW system is $16,250–$25,600 installed, a battery adds $8,350–$17,200, and a panel upgrade adds $1,350–$4,100 if your panel is full.
| Line on the quote | Low | Typical | High |
|---|---|---|---|
| 8 kW system, standard panels | $16,250 | $19,800 | $25,600 |
| 8 kW system, premium panels | $17,850 | $22,750 | $31,950 |
| Tesla Powerwall 3, added at install | $10,700 | $13,700 | $17,200 |
| Main panel upgrade (to 200 amps) | $1,350 | $2,250 | $4,100 |
| Tile roof, extra | $880 | $1,550 | $2,200 |
| Ground mount, extra | $3,550 | $5,750 | $8,850 |
| Critter guard | $620 | $1,050 | $1,500 |
| String inverter replacement (later) | $1,400 | $2,150 | $3,250 |
Standard vs premium panels in St. Petersburg: the gap on 8 kW is about $2,950. Premium panels pay off on small or shaded roofs where you need more power per square foot; on a big sunny roof, standard panels are the better buy.
What moves a solar quote in St. Petersburg:
- System size — bigger systems cost less per kW: about $2,600 at 6 kW against $2,400 at 10 kW.
- Panel and inverter brand — premium panels run 10–25% more; microinverters cost more than one string inverter but last longer.
- The roof — tile adds $880–$2,200, a ground mount $3,550–$8,850, and a worn roof should be replaced first.
- The electrical panel — a full or 100-amp panel can add $1,350–$4,100 for an upgrade.
- Who sells it — sales and marketing are about 15% of a typical price; local installers often quote less than national brands.
Ask every St. Petersburg installer for the same five things: system size in kW, panel and inverter models, the price per kW, the warranty terms, and what roof, panel and permit work is included. Compare those lines, not the total. Get a quote for your solar install →
Solar Panel Cost in St. Petersburg by System Size
A 6 kW system is $12,750–$20,050, 8 kW is $16,250–$25,600, and 10 kW is $19,700–$31,050, installed with standard panels, before any state or utility incentive.
Worked example: a St. Petersburg home using about 1,050 kWh a month gets an 8 kW system at $19,800. If the panel is 100 amps, add an upgrade at $2,250 for $22,050. Add a Powerwall 3 in the same job and the total is about $35,050.
A larger home with central AC or an EV may need 10–12 kW: $24,050 for 10 kW, or $29,600 for 12–13 kW at typical prices. Premium panels on 10 kW run $21,700–$38,800.
St. Petersburg Solar Panel Costs by System Size
| System size | Cost | Best for |
|---|---|---|
| 4 kW system — about 18 kWh a day | $9,450–$14,900 installed | Small home or condo; low bills or a small roof |
| 6 kW system — about 26 kWh a day | $12,750–$20,050 installed | Smaller home or modest power use |
| 8 kW system — about 35 kWh a day | $16,250–$25,600 installed | Typical home; about 1,050 kWh a month of use |
| 10 kW system — about 44 kWh a day | $19,700–$31,050 installed | Larger home, central AC or one EV |
| 12 kW system — about 53 kWh a day | $23,450–$36,950 installed | Big home, pool or electric heat |
| 15 kW system — about 66 kWh a day | $28,350–$44,550 installed | Very large all-electric home or two EVs |
| 8 kW solar + 13.5 kWh battery | $26,400–$41,950 installed | Backup in outages and evening use where exports earn little |
| 13.5 kWh battery only (no solar) | $10,700–$17,200 installed | Backup without panels; shaded roofs |
Hardware vs everything else: where a St. Petersburg solar quote goes
Panels, inverter, racking and wiring are only about 41% of a typical US solar price. On a $19,800 St. Petersburg job that is roughly $8,100. Sales and marketing take about 15%, design, paperwork and overhead about 20%, installer profit about 16%, and the install labor itself only about 6%.
That is why the payback math matters more than the panel brand. An 8 kW system here makes about 12,800 kWh a year. At Florida's 2024 average of 12.5 cents a kWh across all customers (EIA; home rates usually run higher), that power is worth about $1,600 a year, a simple payback near 12 years. Florida's investor-owned utilities credit exports at the full retail rate, so this estimate is close for most of their customers.
What's included in a St. Petersburg solar quote (and what costs extra)
A standard quote covers the panels, inverter, racking, wiring, the install crew, permits, inspection and the utility hookup paperwork. The headline price often leaves out:
- Roof work — repairs, or $880–$2,200 extra for a tile roof
- Panel upgrade — $1,350–$4,100 if your electrical panel is full or 100 amps
- Critter guard — $620–$1,500 to keep birds and squirrels out from under the panels
- A battery — $8,350–$17,200 for 10–13.5 kWh of storage, if you want backup

Your local market
St. Petersburg is a mid-size solar market. The hardware price is national; labor, permits, sales costs and how many installers compete for the job are local.
System size
An 8 kW system is $16,250–$25,600. A 6 kW system is $12,750–$20,050 and 10 kW $19,700–$31,050; the price per kW drops as the system grows.
Panels and inverters
Premium panels add 10–25% ($17,850–$31,950 for 8 kW). Microinverters cost more upfront than one string inverter but usually carry 20–25 year warranties; a string inverter often needs replacing once ($1,400–$3,250).
Your roof
Clay or concrete tile adds $880–$2,200, a ground mount $3,550–$8,850. If the roof has less than about 10 years left, re-roof first: removing and reinstalling panels later costs $3,100–$7,050.
Your electrical panel
A full or 100-amp panel is a common surprise. Upgrading to 200 amps adds $1,350–$4,100 in St. Petersburg, and it is cheapest done with the solar job.
Adding a battery
A 10–13 kWh battery adds $8,350–$15,800, a Tesla Powerwall 3 $10,700–$17,200. Batteries make the most sense where outages are common or exports earn little.
Permits and the utility in St. Petersburg
Permits and inspections are about 3% of a typical price, and the utility must approve the hookup before you can switch on. Ask who files the paperwork; a good installer does all of it.
- Get three quotes.Same panels, different sales costs. St. Petersburg quotes for 8 kW run $16,250–$25,600; a second and third bid is the fastest way to find the padding.
- Compare the price per kW.Divide each quote by its size in kW. About $2,050–$2,500 per kW is a good St. Petersburg price for standard panels; much above $3,200 needs a reason.
- Size it to your bills, not your roof.Use 12 months of bills. A system that makes more than you use only pays off if your utility credits exports well.
- Fix the roof first.Re-roofing under existing panels means paying $3,100–$7,050 to take them off and put them back.
- Bundle the panel and battery work.A panel upgrade ($1,350–$4,100) or a battery done in the same job shares the permit, the inspection and the utility visit.
- Check state and utility help.Florida exempts solar from the 6% state sales tax and keeps the added home value off your property tax bill. Ask your utility about rebates and how it credits exports before you sign.
Before you pay a deposit to a St. Petersburg solar installer, get these in writing:
- System size in kW and the expected output in kWh a year
- Panel and inverter brand and model
- Price per kW and the total before incentives
- Roof work, tile or ground-mount extras, priced as their own lines
- Any panel upgrade, priced as its own line
- Permit, inspection and utility interconnection, and who files them
- Warranties: panels, inverter, workmanship and roof leaks
- Payment schedule, and what happens if the utility hookup is delayed

$16,250–$25,600 installed for an 8 kW system, and $19,800 is typical. A 6 kW system is $12,750–$20,050 and 10 kW is $19,700–$31,050, before incentives.
What is the price per kW for solar in St. Petersburg?
About $2,500 per kW for an 8 kW system with standard panels, within $2,050–$3,200. Smaller systems cost more per kW and larger ones less.
Is there still a federal solar tax credit in St. Petersburg?
Not for systems you buy. The 30% Residential Clean Energy Credit ended for expenditures made after December 31, 2025, and the IRS treats the expense as made when installation is complete. Lease and PPA companies may still claim a business credit and pass some of it on in their price.
How much does solar with a battery cost in St. Petersburg?
About $26,400–$41,950 for 8 kW of panels plus a Tesla Powerwall 3. A 10–13 kWh battery from another brand adds $8,350–$15,800 to the solar price.
How long does solar take to pay off in St. Petersburg?
Roughly 12 years for a typical 8 kW system at Florida's 2024 average power price from EIA (12.5 cents a kWh across all customers), with every kWh worth the full price. Florida's investor-owned utilities credit exports at the full retail rate, so this estimate is close for most of their customers.
How much power will an 8 kW system make in St. Petersburg?
About 35 kWh on an average day, or 12,800 kWh a year, based on about 5.5 peak sun hours a day for Florida in NREL data.
Do I need a new electrical panel for solar in St. Petersburg?
Not always. Many 200-amp panels take solar as they are. A full or 100-amp panel may need an upgrade, about $1,350–$4,100 here.
What does solar panel cleaning and upkeep cost in St. Petersburg?
Cleaning is $130–$440 a visit and a health check $130–$310. Many roofs never need cleaning; rain does most of it. Budget $1,400–$3,250 for one string inverter replacement over the life of the system.
How much does it cost to remove solar panels for a new roof in St. Petersburg?
$3,100–$7,050 to take about 20 panels off and put them back, on top of the roof itself.
What permits does solar need in St. Petersburg?
A building or electrical permit, an inspection, and the utility's approval to connect. Your installer should file all of it; permits and inspections are about 3% of a typical price.
