Off-Grid Systems: “Solar/Compost Toilet: Value of Non-Standard Systems”

I spent $12,000 on a massive Victron solar system and $1,500 on a Cinderella incinerating toilet. My tiny home was totaled in a flood. The adjuster wrote up the estimate: “Toilet: $200 (Standard porcelain). Generator: $500 (Comparable portable unit).” They didn’t understand that my “appliances” were specialized off-grid tech worth 10x the standard versions.

Key Takeaways

  • Standard Valuation fails Off-Grid: Insurance databases use “Standard Mobile Home” or “Standard RV” parts lists. They price a toilet at $150, not $1,000 for a composter.
  • “Agreed Value” is Essential: You must lock in the total value of the home including these systems upfront.
  • Solar is “Attached Fixture”: Ensure your solar panels are listed as part of the structure value, not “Personal Property.” Structure coverage has lower rates/higher limits.
  • Keep Invoices: Without the invoice proving you bought a $3,000 lithium battery, they will pay you for a $200 lead-acid battery.

The “Why” (The Trap)

The trap is “Like Kind and Quality.”

The policy promises to replace your damaged items with items of “like kind and quality.” But if the adjuster doesn’t know what a “Separett Villa” is, they assume it’s a bucket or a standard toilet.
Off-grid systems are niche. Adjusters are generalists. They use software like Xactimate that defaults to standard construction materials unless manually overridden.

The Investigation (My Analysis of Valuation)

I checked how to insure a $50k off-grid setup.

The Appraisal Method

  • The Strategy: Before binding coverage, send an itemized list of the off-grid components to the underwriter.
  • The Result: The carrier (e.g., Foremost) accepts the higher “Stated Value” of the home. Instead of insuring a $60k shell, you insure a $90k system.

  • The Alternative: If your solar array is massive (ground mount), you might need a separate “Renewable Energy” rider.
  • The Cost: Adds ~$50/year but guarantees replacement cost for panels and inverters.

Comparison Table

Water$0 (City hookup)$2,000 (Filtration/Tanks)-$2,000

Step-by-Step Action Plan

  1. Create a “System Inventory”: Don’t just list “Toilet.” List “Cinderella Comfort Incinerating Toilet – $1,500.”
  2. Photograph Model Numbers: Open your inverter bay. Take clear photos of the Victron/Battle Born labels. Upload to the cloud.
  3. Review “Agreed Value”: When buying the policy, ask: “Is this Agreed Value? If I have a total loss, do I get the full $100,000 limit, or do you depreciate my batteries?”
  4. Protect the Tech: Install surge protectors. Solar systems are sensitive to lightning. If you don’t have surge protection, they might deny a lightning claim for “Improper Installation.”

FAQ

Are composting toilets legal for insurance?
Yes, usually. Insurance doesn’t care about the plumbing code as much as the value. However, if the toilet causes a “sewage spill” (liability), make sure your policy doesn’t have a “Pollution Exclusion.”

Does insurance cover my batteries freezing?
No. That is “Temperature/Weather” damage or “Maintenance.” You must keep them heated.

Is theft of solar panels covered?
Yes, if attached. If they are ground-mounted portable panels, they fall under “Personal Property” and might have a lower limit.
