Power Your Property Without the Grid
Building on land without utility access? Off-grid solar can cost less than a grid connection — and you’ll never see a utility bill.
Why Go Off-Grid?
Three reasons to choose solar over grid connection.
Save Money
Grid extension in North Idaho runs $34,000–$70,000+ per mile. Off-grid solar often costs the same or less — with $0 monthly bills.
True Independence
No utility company, no rate increases, no outages from downed lines 30 miles away. Your power, your control of your energy future.
Reliable Power
24/7, 365 days a year. No moving parts, no fuel, minimal maintenance. Solar panels last 25+ years.
The Real Cost: Grid vs. Off-Grid Solar
Most people are surprised to learn off-grid solar is often cheaper than connecting to the grid.
Is Off-Grid Solar Right for You?
Off-grid solar makes sense if you:
- Have property without utility access
- Value self-reliance and energy independence
- Are building new on rural acreage
- Are concerned about rising electricity costs
Want reliable power with no monthly bills?
- Lower total cost over 25 years
- No grid infrastructure needed
- Predictable lifetime costs
- Minimal maintenance required

How an Off-Grid System Works
Four components working together to give you reliable, silent power 24/7.
Solar Panels
Convert sunlight into electricity. Typically sized 10–20 kW for a residential off-grid system. Minimal maintenance, 25+ year lifespan.
Charge Controller
Manages the flow of electricity from the panels into the battery bank. Prevents overcharging and optimizes charging based on available sunlight.
Battery Bank
Stores excess solar energy for use at night or during cloudy periods. Sized based on your daily energy consumption and local weather patterns.
Inverter
Converts stored DC power into AC electricity for your home. Provides the same 120V / 240V you’re used to from a grid connection.

- Custom system design: daily use, winter conditions, desired battery autonomy, generator strategy, and future expansion plans.
- Equipment selection and installation: compatible solar, battery, inverter, and control equipment with mounting, wiring, permitting, inspections, and commissioning.
- Training and support: system operation, monitoring, maintenance basics, and what to do during extended low-sun periods.
Frequently Asked Questions
How much solar do I need for my home?
A small cabin might need 2–4 kW of solar panels, while a larger home could require 10-20 kW or more. We size your system based on your annual energy consumption, which we determine during the site assessment. Factors like your appliances, heating method, and desired lifestyle all impact the final size.
What about winter and cloudy days?
We design North Idaho systems for winter conditions. Solar output is lower in winter, so we size your battery bank to carry you through several cloudy days. Many off-grid systems are designed for 3–5 days of autonomy (meaning the battery alone can power your home for that long without any solar input). On extended cloudy periods, a backup generator provides additional charging.
How long does a system last?
Solar panels typically last 25–30 years and degrade very slowly (about 0.5% per year). Lithium batteries can last 10–15 years with modern battery management systems. Charge controllers and inverters often last 10–20 years. Most components are replaceable without replacing the entire system, so your investment is protected for decades. In addition, the system can be designed with redundancy in mind to keep things running even in the case of a partial equipment failure.
Is off-grid solar really cheaper than connecting to the grid?
For many North Idaho properties, yes. Grid extension costs are $34,000–$70,000+ per mile. Off-grid solar systems often fall in the $35,000–$65,000 range. Beyond upfront cost, the grid-connected home pays $120–$250+ monthly (and climbing), while off-grid systems have $0 monthly bills. Over 25 years, off-grid is often $30,000–$80,000 cheaper.
Can I expand my system later?
Yes, we design systems with future growth in mind. If you decide to add an EV charger, expand your home, or increase your energy consumption, we can add solar panels and battery capacity. Charge controllers and inverters are sized to accommodate this expansion without major re-wiring or equipment replacement.
What about generators?
In the winter, short days and extended cloudy weather, particularly in North Idaho make running solely off solar challenging. A propane or diesel generator is the solution to charge the batteries when they get low and the sun is not available. We can integrate a generator into your system so it charges the battery automatically if it drops below a set level. The amount you will need to run a generator in the winter depends on your energy usage, and how much battery and solar capacity we install. Typically, for an average install, we try to keep the generator usage minimal from March through October with December and January usually needing more generator support because of the extremely short days and weather. However, if you get lucky and get a bright sunny day in the middle of winter, that can be enough to bring your batteries all the way back to full without ever having to burn a drop of fuel.
Bonus Trivia! Did you know that Solar Panels are actually more efficient in the cold weather than in the hot summer sun?
