Power Your Property Without the Grid

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.

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.

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.

For many North Idaho properties, yes. GridZero experience ranges put grid extension around $34,000–$70,000+ per mile and typical off-grid systems around $35,000–$65,000 — not a utility tariff or a site quote. Beyond upfront cost, the grid-connected home often pays $120–$250+ monthly (illustrative), while off-grid systems have $0 monthly utility bills. Over 25 years, off-grid is often $30,000–$80,000 cheaper in that illustrative framing. Bring your utility quote for an apples-to-apples compare.

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.

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?

Bring the quote plus a load list. We’ll map an off-grid system range against extension + ongoing bills with transparent assumptions. Site experience ranges are a starting point — your utility’s numbers win for the extension side. Call or text (208) 244-7304 or use the contact form.

Depends on location (KEC, Avista, NLI, or other). Confirm territory with the utility; we’ll help you interpret the quote in consult.

Yes — send panel datasheet, inverter/MPPT model, and site details. Start with our PV String Calculator for cold Voc limits, then ask us to verify before you buy. Call/text (208) 244-7304 or contact us.

We design custom systems and can help DIY buyers with design review and sizing. We are not a kit retailer. Ask about a design review — we’ll tell you what it includes before you commit.

Often yes — the path depends on county and whether you energize or connect equipment. Consulting should flag the code path; utility energize rules (for example with some cooperatives) may require electrical inspection before energize. Confirm local requirements for your parcel.
