Complete Energy Independence
Off-grid solar systems provide complete energy independence by operating entirely separate from the electricity grid. These systems are designed to generate, store, and manage all the electricity your property needs without any connection to utility power.
Perfect for remote locations, rural properties, and anyone seeking true energy self-sufficiency, off-grid systems give you full control over your power supply while eliminating monthly electricity bills.
Our off-grid solutions are custom-designed to meet your specific energy needs, ensuring reliable power day and night, regardless of your location or access to traditional power infrastructure.
Advantages of Off-Grid Systems
Location Freedom
Build and live anywhere without worrying about grid connection costs or availability. Perfect for remote cabins, farms, and rural properties.
No Electricity Bills
Eliminate monthly electricity bills completely. Once your system is installed, your power is essentially free for the life of the equipment.
Grid Outage Protection
Never worry about power outages or grid failures. Your off-grid system operates independently, providing continuous, reliable power.
Environmental Impact
Reduce your carbon footprint with 100% clean, renewable energy. Off-grid living is the ultimate expression of sustainable living.

Custom System Design Process
Every off-grid system is custom-designed based on your specific energy needs, location, and budget. Our comprehensive design process ensures your system will provide reliable power year-round.
Energy Assessment
We analyze your energy usage patterns and requirements to determine your daily power needs.
Site Evaluation
Assessment of your location, solar exposure, and installation considerations for optimal system placement.
System Sizing
Calculation of solar array size, battery capacity, and component specifications to meet your needs.
Backup Planning
Integration of generator backup for extended cloudy periods and high-demand scenarios.
Our off-grid designs typically include 3-7 days of battery autonomy to ensure power availability during extended cloudy weather, with generator backup for additional security.
Cost & Investment Analysis
While off-grid systems require a higher initial investment than grid-tied systems, they eliminate ongoing electricity costs and provide complete energy independence. The table below shows typical system costs and components.
| System Size | Typical Application | Components Included | Estimated Cost |
|---|---|---|---|
| Small (2-3kW) | Weekend cabin, tiny home | Solar panels, battery bank, charge controller, inverter | $12,000 - $18,000 |
| Medium (5-6kW) | Full-time small home, farm building | Larger solar array, expanded battery bank, complete system | $20,000 - $30,000 |
| Large (8-10kW) | Family home, small business | Large solar array, extensive battery storage, backup generator | $35,000 - $50,000 |
| Commercial (10kW+) | Farm operations, remote business | Custom commercial system with industrial components | $50,000+ |
Note: Costs vary based on specific components, installation complexity, and location. All systems include professional design, installation, and commissioning. Financing options available.
Long-Term Value
While the upfront cost is significant, consider that an off-grid system:
- Eliminates monthly electricity bills permanently
- Adds value to your property
- Provides power where grid connection might cost $20,000-$100,000+
- Offers protection against rising energy costs
The payback period compared to grid extension is often immediate, and compared to ongoing electricity bills typically ranges from 10-15 years.
Frequently Asked Questions
How many days of power will my off-grid system provide?
Most off-grid systems are designed with 3-7 days of battery autonomy, meaning they can power your essential loads for that period without any solar input. This accounts for extended cloudy weather. Systems can be designed with more autonomy if needed, though this increases battery costs.
Do I need a backup generator with an off-grid system?
While not strictly necessary, we strongly recommend a backup generator for most off-grid systems. It provides security during extended periods of poor weather, allows for occasional high-power usage beyond what the solar system can provide, and can help maintain battery health by providing occasional equalization charges.
What maintenance is required for an off-grid system?
Off-grid systems require regular maintenance including: checking battery water levels (for flooded lead-acid batteries), cleaning solar panels, inspecting connections, and monitoring system performance. Lithium battery systems require less maintenance. We offer maintenance packages to keep your system operating optimally.
Can I expand my off-grid system in the future?
Yes, most off-grid systems can be expanded. When designing your system, we consider future expansion possibilities. You can typically add more solar panels, additional batteries, or upgrade components as your needs change. It's most cost-effective to plan for future expansion during the initial design phase.
