We get asked about solar a lot. And honestly? It's complicated.
Solar + battery storage can be an excellent preparedness investment for the right family. But it's not for everyone, and the math matters more than the marketing.
Let's break it down honestly.
The Preparedness Case for Solar
Here's why solar comes up in preparedness conversations:
Grid reliability is declining. The Department of Energy has warned that blackouts are increasing. Whether it's aging infrastructure, extreme weather, or demand outpacing supply - the grid is less reliable than it used to be.
Solar WITHOUT batteries is useless during outages. This is critical. Standard grid-tied solar systems shut off when the grid goes down (for safety reasons). If you want backup power, you need battery storage. Solar panels alone won't keep your lights on during a blackout.
Solar + battery = true energy independence. When the grid fails, your system keeps running. Your refrigerator stays cold. Your medical equipment stays powered. Your family stays comfortable.
The Real Costs
Let's talk numbers. These vary significantly by region, home size, and system capacity:
Basic Backup System: $15,000 - $25,000
- Covers essentials during outages
- Partial solar offset of electric bill
- Small battery bank (8-15 kWh)
Comprehensive Home System: $40,000 - $80,000
- Near-zero electric bills
- Whole-home backup during outages
- Larger battery bank (20-40 kWh)
Complete Independence: $100,000+
- Zero electric bill
- Extended outage capability (days)
- EV charging included
- Maximum battery storage
These are significant investments. No way around it.
The Financial Analysis
The "Renting vs Owning" Framework
Your electric bill is essentially a forever-payment that increases every year. You're renting electricity with annual rent increases. Forever.
Solar + battery is different - you're buying your electricity upfront for the next 20-25 years. Fixed cost. No increases. And you own the system.
Running Your Numbers
To analyze whether solar makes sense for you:
- Know your current electric bill. What do you pay monthly? Annually?
- Factor in rate increases. Electric rates typically increase 3-5% annually. What will your bill be in 10 years? 20 years?
- Get actual quotes. Not estimates from the internet - real quotes for your specific home and usage.
- Calculate the break-even point. How many years until the system pays for itself in avoided electric bills?
- Consider home value impact. Solar typically adds value to your home. In most states, solar installations are exempt from property tax assessment - your home value goes up but your property taxes don't.
When Solar Makes Financial Sense
Solar tends to pencil out better when:
- Your electric bills are high ($200+/month)
- You live in a high-sun area
- Electric rates in your area are high and rising
- You plan to stay in your home long-term
- You have medical equipment requiring reliable power
Solar tends to make less sense when:
- Your electric bills are already low
- You live in a low-sun area
- You're planning to move soon
- Your roof needs replacement (do that first)
Critical Rules for Solar
If you do decide to go solar, follow these rules:
1. Batteries Are Non-Negotiable
For preparedness purposes, solar without batteries is pointless. You need both. Don't let anyone sell you panels without storage if backup power is your goal.
2. Never Lease
Only finance or pay outright. Solar leases are generally a terrible deal - you don't own the system, you can't claim incentives, and it complicates selling your home. Just don't.
3. Get Multiple Quotes
Prices vary dramatically between installers. Get at least three quotes. And verify the company's reputation - solar installation quality matters.
4. Understand Your Incentives
Federal and state incentives change frequently. Research what's currently available in your area. These can significantly impact the financial equation.
5. Size for Your Actual Needs
Don't over-buy or under-buy. A good installer will analyze your actual usage and recommend appropriate sizing. Be skeptical of anyone pushing the biggest system possible.
Alternatives to Consider
Solar isn't the only backup power option:
| Option | Cost | Notes |
|---|---|---|
| Whole-home generator | $10,000 - $20,000 installed | Natural gas or propane, automatic transfer, unlimited runtime with fuel |
| Portable generator | $500 - $2,000 | Manual setup, limited circuits, requires fuel storage |
| Battery backup only | $5,000 - $15,000 | No solar, charges from grid, good for short outages |
| Portable power stations | $500 - $3,000 | Very limited capacity, essentials only, no installation |
Each has tradeoffs. Solar + battery is the premium solution, but it's not the only solution.
Our Take
Solar + battery storage is excellent preparedness - IF the financial math works for your situation AND you follow the rules (batteries required, no leases, multiple quotes).
It's not a must-have for everyone. A good generator setup provides backup power at a fraction of the cost. Many families are well-served by simpler solutions.
But if you:
- Have high electric bills
- Live in a sunny area
- Have medical power needs
- Want long-term energy independence
- Can afford the upfront investment
...then solar + battery deserves serious consideration.
Run your numbers. Get real quotes. Make an informed decision.
Key Takeaway
Solar + battery can be excellent preparedness, but only if the math works for your situation. Critical rules: batteries are required for backup power, never lease, get multiple quotes, and size appropriately for your needs. Alternatives like generators provide backup power at lower cost if solar doesn't pencil out.
