Custom Off-Grid Systems for Reliable Power
Off-grid solar systems must be carefully designed to match actual energy use, not general estimates.
We design systems for:
- Cabins and seasonal properties
- Full-time off-grid homes
- Remote and hard-to-access sites
- Larger homes and properties with significant electrical loads
Each system is tailored to your usage patterns, equipment needs, and long-term plans, with an emphasis on reliability, serviceability, and realistic expectations.

Off-Grid Expertise Built on Experience
Fire Mountain Solar was founded in 2001, but our experience with off-grid power began even earlier. In 1996, our founders purchased a rural property without access to utility power and chose to power their home with off-grid solar.
That firsthand experience shaped the way we approach off-grid system design today. We understand that reliable power isn’t just about installing solar panels and batteries β it’s about designing a system that works for the way you actually live.
What Goes Into a Reliable Off-Grid System
Designing an off-grid system requires more than simply adding up the wattage of your appliances. We look carefully at how and when you use power, your available solar resource, battery storage, backup options, and the demands of your property.
Our approach includes:
- Accurate load analysis and system sizing
- Proven equipment choices for off-grid use
- Thoughtful system design without unnecessary complexity
- Clear explanations so you understand your options and tradeoffs
The goal is a system that provides reliable power and works well for the way you actually use your property.

A Straightforward, No-Pressure Process
We keep the process simple and transparent:
- Learn about your property and goals β We start by understanding how you plan to use the property and what you need from your power system.
- Design a system that fits your needs β We design around your actual energy use, property, and priorities.
- Provide clear recommendations and pricing β We’ll explain your options, answer your questions, and give you straightforward pricing so you can make an informed decision.
No pressure. No gimmicks. Just the information you need to decide if off-grid solar is right for you.
