Meet the Homeowner
Location: Crestview, Florida (Okaloosa County)
Property Type: Single-family home (2,100 sq. ft.)
Utility Provider: Florida Power & Light (FPL)
System Installed: 9.6 kW rooftop solar + 10 kWh battery backup
Installer: MSM Solar LLC
Like many homeowners in Northwest Florida, the Smith family was seeing their electric bills rise steadily year after year. During summer months, when air conditioning ran around the clock, their monthly utility costs exceeded $300–$340.
In early 2024, they decided it was time to explore solar as a long-term solution.
“We weren’t just thinking about saving money; we wanted something that made financial sense for the next 25 years,” says Tom Smith, Crestview homeowner. “MSM Solar came highly recommended because they focus on local installs, not out-of-state sales teams.”
Step 1: Energy Audit & System Design
The MSM Solar team began with a comprehensive site assessment and energy audit, analyzing the Smiths’ annual consumption patterns.
Key insights:
- Average monthly usage: 1,280 kWh
- Peak usage: July–September (HVAC-heavy months)
- South-facing roof pitch: 28° with minimal shading
- Roof material: Architectural shingle (installed 2019)
Using these details, the design team proposed a 9.6 kW grid-tied solar system featuring:
- 24 x 400W Tier-1 monocrystalline panels (black-on-black aesthetic)
- Enphase IQ8 microinverters for module-level performance
- 10 kWh Enphase IQ Battery for partial-home backup
- IronRidge XR100 hurricane-rated racking system (160 mph certified)
The system was modeled to offset approximately 70% of the home’s total annual consumption, with battery storage providing overnight coverage and storm resilience.
Step 2: Permitting & Installation
Crestview solar permitting is handled under Okaloosa County jurisdiction, which requires:
- PE-stamped structural drawings
- Electrical one-line diagram
- Wind-load analysis (ASCE 7-22, 150 mph zone)
MSM Solar managed the full submission and approval process, which took just 8 business days thanks to pre-approved engineering partners.
Installation Details
- Duration: 2 days (roof + electrical work)
- Inspection & interconnection: Completed in 10 days
- Utility approval: FPL issued Permission to Operate within 2 weeks
“I was impressed by how professional and fast they were,” says Tom. “They handled everything, the permits, the HOA packet, the FPL paperwork, all I had to do was sign off.”
Step 3: The Results – 60% Bill Reduction
Once activated in June 2024, the system immediately began producing clean power. Over the first six months, MSM Solar monitored production through the Enphase Enlighten app to verify accuracy and performance.
Results (June–December 2024):
| Month | Utility Bill (Before Solar) | Utility Bill (After Solar) | Solar Offset (%) |
|---|---|---|---|
| June | $310 | $135 | 57% |
| July | $340 | $142 | 58% |
| August | $320 | $128 | 60% |
| September | $285 | $112 | 61% |
| October | $240 | $98 | 59% |
| November | $220 | $85 | 61% |
Average Monthly Savings: $160–$200
Total First-Year Savings (Projected): ~$2,200
Even during cloudy fall weeks, the system continued producing efficiently, with battery backup kicking in during brief outages and evening hours.
Step 4: ROI & Payback Analysis
The Smiths invested a total of $27,800 in their solar + battery system.
Incentives Applied:
- 30% Federal Investment Tax Credit (ITC): –$8,340
- Florida 6% Sales Tax Exemption: Automatically applied
- 100% Property Tax Exemption: Prevented any increase in assessed home value
Net Cost After Incentives: $19,460
Projected Payback: ~7.5 years
Lifetime Savings (25 years): $42,000+
ROI (25 years): ~216%
With a production warranty of 25 years and inverters rated for 25+ years, their system will continue generating savings well past payback.
Step 5: Added Benefits Beyond the Bills
Backup Power During Storms
The 10 kWh battery system provided peace of mind during summer thunderstorms and short outages, powering essential loads like:
- Refrigerator
- Wi-Fi router
- LED lights
- Ceiling fans
- Sump pump
“It’s completely silent compared to our old gas generator,” Tom adds. “We hardly noticed when the power flickered out.”
🌴 Increased Home Value
A 2023 Zillow study shows that homes with solar sell for 4.1% more on average. Based on Crestview’s median home price (~$340,000), that’s a $13,000+ value increase.
🌤️ Environmental Impact
In the first 12 months, their system will offset 11 metric tons of CO₂, equivalent to planting 180+ trees.
System Performance Overview
| Parameter | Detail |

Lessons Learned from the Crestview Project
- Energy Efficiency First:
A pre-install energy audit helped right-size the system, avoiding unnecessary costs while maximizing output. - Choose a Local, Certified Installer:
Local companies like MSM Solar understand Okaloosa County’s wind zones, permitting, and HOA expectations far better than out-of-state sales teams. - Add Battery Backup if You Can:
Even a small battery can keep essential loads running and boost your system’s ROI during outages. - Plan Around Roof Condition:
Installing solar on a newer roof (under 5 years old) ensures your system won’t need to be removed and reinstalled prematurely. - Track Your Data:
With monitoring apps, you can watch production and consumption trends daily, ensuring transparency and peace of mind.
Solar System Payback Breakdown
Here’s how the numbers played out for the Smith family’s Crestview solar project:
| Category | Amount | Notes |
|---|---|---|
| Total System Cost | $27,800 | Equipment, labor, permits |
| Federal ITC (30%) | -$8,340 | 2025 credit |
| Net Cost After Incentives | $19,460 | Out-of-pocket or financed |
| Monthly Bill Savings | $160–$200 | Verified over 6 months |
| Annual Savings | ~$2,200 | Based on FPL rate escalation |
| Payback Period | 7.5 years | |
| 25-Year Lifetime Savings | $42,000+ | Net of degradation |
| ROI | ~216% | Lifetime return on investment |
Even accounting for 0.5% annual degradation and future inverter replacement, the Smiths’ system remains a financially sound investment with substantial long-term payoff.
Why Crestview Is Ideal for Solar
