Comparing Solar Costs: Palm Beach vs. Martin vs. St. Lucie vs. Indian River Counties

Bottom Line Up Front: Solar costs across these four Florida counties are remarkably competitive, with Indian River County offering the lowest costs at $2.09 per watt, followed by St. Lucie County at $2.12 per watt, Palm Beach County at $2.23 per watt, and all counties offering substantial savings potential. However, the 30% federal solar tax credit ends December 31, 2025, making immediate action crucial for maximum savings.


Florida's Treasure Coast and Palm Beach County regions represent some of the most attractive solar markets in the nation, combining abundant sunshine with competitive installation costs and strong utility policies. For homeowners considering solar installation, understanding the cost differences and market dynamics across Palm Beach, Martin, St. Lucie, and Indian River counties can help maximize both savings and energy independence.


Current Solar Costs by County (2025)


Indian River County: The Most Affordable Option


Indian River County, anchored by Vero Beach, offers the most competitive solar pricing at $2.09 per watt as of May 2025. For a typical 5 kW residential system, homeowners can expect to pay between $8,873 to $12,005 before incentives, with an average cost of $10,439. After the 30% federal tax credit, the average price drops by 30%, bringing the out-of-pocket cost to approximately $7,307.


Key Cost Factors:

  • Lower labor costs compared to Palm Beach County

  • Streamlined permitting processes

  • Growing solar installer competition

  • Average residential electricity rate of 13.96 cents per kilowatt hour in areas like Hobe Sound

St. Lucie County: Excellent Value with Strong Infrastructure


St. Lucie County, including Port St. Lucie, offers solar installations at $2.12 per watt as of May 2025. A 5 kW system ranges from $9,011 to $12,191 before incentives, averaging $10,601. After federal tax credits, homeowners pay around $7,421 out of pocket.


Notable Advantages:

  • Strong 20-year savings potential of approximately $22,672 to $22,687

  • Average electric bill of $138.68 per month with electricity costs at 12.27¢ per kWh

  • Access to the Solar and Energy Loan Fund (SELF) for financing assistance

  • Growing solar infrastructure and experienced installer base


Palm Beach County: Premium Market with Higher Costs

Palm Beach County, including West Palm Beach, shows higher costs at $2.23 per watt as of May 2025. A 5 kW system costs between $9,489 to $12,839, averaging $11,164 before incentives. After the federal tax credit, the net cost is approximately $7,815.


Market Characteristics:

  • Premium service market with higher labor costs

  • Average electric bills around $138.68-$138.74 per month with rates of 12.24-12.27¢ per kWh

  • More complex permitting in some municipalities

  • Strong long-term savings potential of about $66,303 over 25 years


Martin County: Balanced Costs with Local Advantages

While specific per-watt pricing for Martin County wasn't detailed in current data, costs generally align with the Florida average of $2.20 per watt statewide. The county offers unique advantages through local programs and geographic positioning.


Local Benefits:

  • Property Assessed Clean Energy (PACE) financing available for homeowners

  • Solar and Energy Loan Fund (SELF) partnership providing low-cost financing options

  • Natural gas dominates electricity generation at 94.96%, making solar a valuable diversification strategy

  • Strategic location between higher-cost Palm Beach and lower-cost St. Lucie markets


Critical Federal Tax Credit Update


Immediate Action Required: Congress has passed legislation ending the 30% residential solar tax credit after December 31, 2025. Homeowners have until December 31, 2025 to pay for or install solar panels and lock in the 30% federal tax credit-an average of $9,000 in savings.


This creates urgency for homeowners across all four counties, as systems that previously paid for themselves in eight to 10 years with tax credits may now take 15 to 20 years to break even without federal incentives.

Hurricane Preparedness: The Battery Storage Advantage


Florida's hurricane-prone climate makes battery storage particularly valuable across all four counties. Recent storms like Hurricane Helene and Hurricane Milton demonstrated the critical importance of backup power systems.


Battery Storage Costs and Benefits:

  • Average storage system cost in Florida is $1,300 per kWh as of April 2025

  • Typical 13 kWh system ranges from $14,365 to $19,435 before incentives

  • Solar panels paired with battery storage can keep essential things like fridges, medical devices, and phones working during grid outages

  • During extreme weather events like hurricanes, homes equipped with solar energy and battery storage can stay powered even when the grid goes down

Blue Energy Electric provides comprehensive Battery Backup Storage solutions, including SI-30 systems specifically designed for Florida's challenging weather conditions.


Local Utility Considerations


All four counties are primarily served by Florida Power & Light (FPL), which offers several advantages:


FPL Net Metering Benefits:

  • Florida law requires net metering customers are compensated at the retail rate

  • FPL customers are credited for the energy produced by their solar systems at their electricity rate

  • Credits roll over from month to month but reset at the end of a 12-month period

  • Any excess credits will be converted to cash at a reduced rate per kWh, typically ranging from 3 to 5 cents per kWh


System Sizing and Energy Usage Patterns


Average System Requirements by County:

  • Indian River County: Average homeowner needs a 16.08 kW system costing about $32,774 before incentives

  • St. Lucie County: Average homeowner needs a 14.05 kW system costing about $30,123 before incentives

  • Palm Beach County: Varies by municipality, with larger systems typically needed for higher energy consumption

The variation in system sizes reflects different energy usage patterns, home sizes, and local climate factors affecting air conditioning needs.

Local Market Dynamics and Installation Factors


Installer Competition and Availability

All four counties benefit from competitive solar markets, though availability and pricing can vary:

  • Palm Beach County: Highest installer density but premium pricing

  • St. Lucie County: Strong competition among local and regional installers

  • Indian River County: Growing installer presence with competitive pricing

  • Martin County: Balanced market with access to installers serving the broader Treasure Coast


Permitting and Interconnection

Permits and fees can add a few thousand dollars to your installation, accounting for about 8% of the total cost. Florida requires homeowners to get permits before installing rooftop solar, typically costing $50 to $250, though many installers include these fees in their pricing.


Local permitting efficiency varies:

  • Indian River County offers streamlined processes

  • Palm Beach County can have more complex requirements in some municipalities

  • St. Lucie and Martin counties generally offer efficient permitting

Financial Considerations and Payback Periods

County-by-County Payback Analysis:

  • Indian River County: Fastest payback at approximately 7.82 years

Long-Term Value and Property Impact

Solar installations add substantial value to properties across all four counties:

  • Going solar can save Florida homeowners over $21,000 in electricity costs over 25 years

  • Increased property values, particularly attractive to Florida buyers

  • Protection against rising electricity costs

  • Enhanced energy independence and hurricane preparedness


Making the Right Choice for Your County

Take Action Before Year-End


With the federal tax credit ending December 31, 2025, and installation timelines typically running two to four months, immediate action is essential. The solar industry expects significant demand in the second half of 2025, potentially leading to longer wait times for those who delay.
