⚡ 1. What Size Solar System a Typical Florida Home Needs

For most homes in Florida:

✅ Typical system size:

• 7 kW – 10 kW = average home

• 10 kW – 12 kW = large home (pool, EV, heavy AC)

Why Florida systems are efficient:

• ~5.5–6 peak sun hours/day (very high) (EcoGen America)

• That means smaller systems produce more power than in northern states

📊 Real-world sizing examples:

Home Type	Recommended Size	What It Covers
Small home	5–6 kW	60–80% of usage
Average home	7–9 kW	~100% of usage
Large home	10–12 kW	Full coverage + EV/pool

👉 Experts say a ~8 kW system is the sweet spot for a ~2,000 sq ft Florida home (Green Energy Calculators)

💰 2. Cost of Solar Panels (Florida 2026)

💵 Average cost (panels only):

• $18,000 – $28,000 (typical 8–10 kW system) (EcoGen America)

• Around $2.2–$2.8 per watt (EnergySage)

💵 After incentives (when applicable):

• Roughly $13,000 – $18,000 for many systems (SolarReviews)

📌 Key takeaway:

• Most Florida homeowners land around:
  👉 ~$15K–$20K out-of-pocket for solar only

---

🔋 3. Cost of Battery Backup (Storm-Ready Upgrade)

This is what turns solar into a hurricane-resilient system.

💵 Battery cost (2026):

• $6,000 – $18,000 installed (Solar)

• ~$1,000 per kWh installed (after incentives) (Solar)

🔋 Typical battery sizes:

Battery Size	What It Powers
5–10 kWh	Essentials only (lights, WiFi)
10–15 kWh	Fridge + outlets + lights
20+ kWh	Partial home backup

👉 Most Florida storm setups use:

• 10–20 kWh battery (1–2 days of essentials)

---

🌀 4. Total Cost of a Storm-Ready Solar System

🧾 Full system (solar + battery):

System Type	Total Cost
Solar only	$15K – $20K
Solar + small battery	$20K – $30K
Solar + full backup battery	$30K – $45K+

👉 Realistic “storm-ready” setup:

• 8–10 kW solar

• 10–15 kWh battery
  💡 Typical cost: $25K–$35K

---

🏠 5. What a Storm-Ready System Actually Powers

Experts recommend a “critical loads panel”, not whole-home backup.

🔌 Essential loads:

• Refrigerator

• Lights

• Internet / router

• Phone charging

• Medical devices

• Garage door

❌ Usually NOT included (unless large battery):

• Central AC

• Electric stove

• Whole-house cooling

👉 Running full AC requires very large (expensive) battery systems

---

⚠️ 6. The Most Important Insight (Florida-Specific)

From both experts and real homeowners:

Solar alone does NOT work during outages.

Without a battery:

• Your system automatically shuts off when the grid goes down.

With a battery:

• You get continuous power during storms

This is why:
👉 In Florida, solar is shifting from “saving money” → “survival & resilience”

---

🧠 7. Smart Strategy (What Experts Recommend)

Instead of overspending upfront:

Step-by-step approach:

1. Install solar panels first (8–10 kW)

2. Make system battery-ready

3. Add battery later (when prices drop or risk increases)

💡 This reduces upfront cost but keeps flexibility.

---

📌 Bottom Line

• Typical Florida home needs: 7–10 kW system

• Solar cost: ~$15K–$20K

• Battery cost: $6K–$18K

• Storm-ready system total: $25K–$35K

🌴 Florida Reality Check (Important)

Given hurricane risk:

👉 The best ROI in Florida isn’t just savings
👉 It’s keeping power when everyone else loses it

👉 We also want to reach out to companies with large capacity fees pending as we move forward.
