Popular Solar Options

There are two main types of solar energy systems used in residential settings in Florida:

Solar Photovoltaic (PV) Systems

Solar PV systems convert sunlight directly into electricity using solar panels typically installed on the roof. The electricity generated can power your home or be sent back to the grid. Solar PV systems require little maintenance and have a lifespan of 25-30 years.

Solar Thermal Systems

Solar thermal systems use solar energy to heat water for domestic or pool heating. They utilize solar collectors installed on the roof that absorb and transfer heat to a storage tank. Solar thermal systems can provide up to 80% of a household’s hot water needs.

Solar PV systems are the most common for full home solar installations, while solar thermal tends to serve supplementary water heating needs.

Key Factors in Solar Costs

Several key factors affect the overall cost of installing solar panels in Florida. The three main components that influence pricing are system size, equipment costs, and installation complexity.

System size refers to the number of solar panels and the power output measured in kilowatts. Larger solar arrays generate more electricity but also cost more upfront. The size needed depends on factors like roof space, energy usage, and budget. The solar panel equipment itself including panels, inverters and racking makes up a significant portion of the overall expense.

Higher efficiency solar panels generally cost more but may have faster payback periods. Inverters must be properly sized for the system and high quality units are recommended. Installation costs can vary greatly based on the roof type, accessibility, and structural upgrades required. More complex installations on steep, tile, or otherwise challenging roofs will be more expensive than simple installations on accessible shingle roofs.

Finally, local electricity rates affect the value of the solar energy produced. Areas with high energy prices will see faster paybacks on solar investments compared to low-cost utility regions.

Average System Size Needed

The average home size in Florida is around 1,500 square feet. Typical electricity usage for a Florida home this size is 1,000-1,500 kWh per month. To fully offset this electricity usage, most homeowners will need a 6-8 kW solar panel system.

A system this size will have around 18-24 solar panels, with each panel rated at around 330 watts. 6 kW is generally the minimum size recommended for the average home, while 8 kW provides extra capacity to power larger homes and amenities like pools.

While exact solar sizing depends on several factors like roof space and energy efficiency, a 6-8 kW system is a good starting point to meet the electricity demands of most Florida homes. This provides enough capacity to zero out electric bills without oversizing the system.

Equipment Costs

The equipment needed for a residential solar installation includes solar panels, racking, inverters, and wiring. The costs can vary significantly depending on the types and brands selected.

For solar panels, costs typically range from $0.75 to $0.85 per watt for mid-range products from reputable brands like LG, Panasonic and SunPower. Economy panels from lesser known brands can cost $0.50 to $0.65 per watt. Premium panels with higher efficiencies and better warranties range from $0.90 to $1.00 per watt.

Inverters usually cost $0.20 to $0.30 per watt. Quality inverter brands like Enphase and SolarEdge are more reliable but also more expensive. Racking and wiring add another $0.10 to $0.20 per watt.

When installing a solar array, there are economies of scale. A larger system benefits from spreading fixed costs like permits and labor across more equipment. Most experts estimate around $3.00 per watt for a smaller 4 kW system, decreasing to around $2.50 per watt for a larger 8 kW system.

Installation Costs

The labor and materials needed for installing solar panels make up a significant portion of the overall system cost for homeowners. Installation prices are driven by several key factors:

Labor – Solar installers typically charge around $150-250 per hour for 2-3 workers to complete the installation. Simple roof installations may only take 8-16 hours, while more complex projects can take 40+ hours.
Permitting – Most local jurisdictions require permits for solar installations, costing $200 on average.
Inspection – An electrical inspection will be needed, adding another $100-$150 to the overall cost.

Interconnection fees – Fees to connect the system to the grid range from $50-$150.

As an example, a straightforward solar installation on a sloped roof may cost around $3,000-5,000 for labor and fees. A more complex install across multiple roof planes or incorporating battery storage could cost up to $10,000 or more when factoring the additional labor and complexity.

It’s important for homeowners to understand their specific roof type, electrical setup and permitting requirements when estimating total installation costs.

Federal and State Incentives

There are a few key federal and state incentives that can help reduce the cost of going solar for Florida homeowners. At the federal level, homeowners can claim a 26% tax credit for systems installed in 2022-2023. This tax credit covers both the cost of equipment and installation. For a typical 5kW solar system costing $15,000, a homeowner could get back $3,900 on their federal taxes over one or two years. The tax credit does step down to 22% for systems installed in 2024 before expiring completely in 2025, so act soon to maximize savings.

For Florida residents, utilities are required to offer net metering, which allows excess solar energy to be sold back to the grid. This can lead to additional cost savings. Florida also exempts 80% of the appraised value of a solar system from property taxes, reducing costs further. Overall, state and federal incentives could save a Florida homeowner $5,000 or more in going solar, making it very cost-effective.

Operation and Maintenance

Once your solar energy system is installed and operational, there are some ongoing costs to keep it running efficiently. These are referred to as operation and maintenance (O&M) expenses.

On an annual basis, O&M costs for a residential solar system average around $80-$160 per year. This covers basic system monitoring, cleaning the panels, and making any minor repairs or adjustments. Most solar panels come with 20-25 year manufacturer warranties, so major equipment repairs are uncommon in the first 5-10 years.

However, some key components of the system will need to be replaced periodically. Inverters, which convert the solar energy into usable AC electricity, typically last 10-15 years before needing replacement. This can cost anywhere from $500-$2000 depending on system size. Solar batteries also wear out after 5-10 years, costing $3000-$6000 to replace.

When budgeting for long-term solar system costs, factor in about $300 per year on average for O&M expenses. Also plan on one major equipment replacement of the inverter and/or batteries during the system’s 25-30 year lifespan. Doing so allows you to accurately estimate the total lifecycle costs and payback period.
