Solar panels, batteries, inverters — real brands, real prices
Live 24-hour cutaway (24 h = 48 s) — the same homestead as the Water page, seen through the energy lens: follow every watt from the sun on the roof to the socket.
Once you own a piece of land, the next chain is the one tying you to the utility company. Every winter storm becomes their grip on your kitchen, your lights, your local AI. Energy autonomy means: when the grid drops, your sanctuary keeps breathing.
This page is the practical catalogue — the actual brands, the actual capacities, the actual costs as of 2026. No affiliate links, no influence, just what works.
— The energy layer of the LAND Fund
Tick and adjust to match your life — the last two lines give you the price of your independence.
Assumptions: winter-realistic yield ≈ 1.8 kWh/day per installed kWp (sized for the short months — see “The December Problem” below), ≈ 1.5 days of battery autonomy, equipment-only May 2026 prices interpolated from the three profiles below. “To be independent” is that one-time hardware cost; “Per year” is the battery-replacement fund (LFP set aside over ~12 years) — the sun charges free, so there is no monthly bill. Sized for a northern winter — in sunnier latitudes the same array yields two to three times more, so these numbers are the safe worst case anywhere on Earth. A starting estimate, not a quote — get a real load audit before you buy.
| Use | Daily draw | Notes |
|---|---|---|
| Refrigerator | 1.0–1.5 kWh | Modern inverter compressor — the old garage fridge eats triple |
| Chest freezer | 0.8–1.2 kWh | A full freezer holds its cold better than an empty one |
| LED lighting | 0.3–0.6 kWh | The whole house — the bulb war is over, the LED won |
| Laptops & electronics | 0.5–0.8 kWh | Two laptops, the router, the phones |
| Big TV | ~0.4 kWh (2 h) | Screen size is a power rating in disguise |
| Gaming tower | ~0.7 kWh (1 h) | And the screen follows the tower — one more TV hour |
| Satellite internet | 1.0–1.5 kWh | The dish is always listening — and heats itself in snow |
| Well pump | 0.5–1.2 kWh | ~1 kWh lifts a whole day of water — the litres are on the Water page |
| Irrigation pump | 0.3–0.6 kWh, summer | Drip lines at dawn — the garden drinks while the sun climbs |
| UV water treatment | 0.2–0.4 kWh | An always-on lamp between the cistern and the tap |
| Washing machine | 0.4–0.7 kWh / load, cold | The dryer is the trap — the clothesline is a 0 kWh dryer |
| Microwave | 0.2–0.4 kWh | Big watts, short minutes — the minutes win |
| Local AI server | 0.7–1.2 kWh | Your memory, offline — a Jetson-class box sips, a GPU tower gulps |
| Electric cooking | 1.0–2.0 kWh | Induction — and propane is the classic off-grid dodge |
| Electric water heater | 2.5–4.0 kWh | Two short showers — the biggest resistive load in the house |
| Fans | 0.3–0.6 kWh | Hot nights for pennies — the A/C's honest little brother |
| Small split A/C | 3–6 kWh, hot month | Daily average — an inverter unit modulates instead of slamming |
| Electric fence | ~0.1 kWh | The cheapest guardian on the Animals page |
| Workshop | 1–2 kWh (~1 h) | Saw, drill, compressor — short bursts, big peaks: mind the inverter surge |
| E-bike charging | 0.4–0.6 kWh | 50 km of range per charge — the cheapest vehicle on the land |
| Heat pump | 8–16 kWh, annual avg | Cold climate — "The December Problem" below, in a single line |
| EV charging | ~8 kWh (40 km/day) | A small house's worth of demand parked in the driveway |
| Phantom standby rule | +0.2–0.5 kWh | Chargers, clocks, standby LEDs — one switchable power bar kills the vampires |
| December rule | 1 kWp ≈ 1.8 kWh/day | Size for the darkest month — the calculator above is built on it |
The calculator's three default ticks — fridge, LED lights, laptops — are the honest 2.2 kWh minimum: a Tiny Cabin. Add the well pump, the washing machine, electric cooking and the local AI server and you land at ≈ 5.9 kWh/day — about 3.6 kWp of panels, ~9 kWh of battery, ~$9,900. Still barely half the Small Off-Grid House card below.
A small generator (propane, diesel, or biofuel) is the honest backup for January weeks where the sun barely shows. Hybrid inverters can merge solar, battery, and generator into a single seamless AC output.

Reading the table: efficiency is panel-level (how much sunlight is converted). 21–22 % is excellent for residential. Power (W) is "STC" — laboratory peak. Real-world output is 70–85 % of that. Higher wattage panels = fewer panels for the same kW system, lower per-watt installation cost, but heavier and harder to handle alone. Prices vary widely; buy in pallets when possible.

LFP (Lithium Iron Phosphate) is the standard for residential storage in 2026: longer cycle life (5 000–10 000), tolerates 100 % depth of discharge, fire-safe, no cobalt. NMC (Nickel Manganese Cobalt) is denser but ages faster and carries higher fire risk under abuse — common in EVs, less ideal for stationary home use. For a sanctuary, choose LFP.

Typical monthly output of a fixed solar array in a northern climate (~47° N), in kWh per installed kWp. July ≈ 145, December ≈ 40 — the same array produces 3–4× less in the dead of winter. That's the number the brochures never show.
Size your array for November, not July. Summer surplus costs nothing; a winter deficit is paid for in generator hours.
A few dozen hours a year is all it takes: it covers the two grey weeks that even a big array can't save.
Never heat with solar electricity in January. Wood or propane carries the thermal load — solar carries everything else.
Prices reflect equipment only, May 2026. US-dollar figures are shown first; for non-US manufacturers, the approximate price in the brand's home currency is shown in parentheses. Add ≈ 30–60 % for installation, racking, wiring, permits, and an electrician for inspection. Always price-check at the moment of purchase — solar prices fell roughly 20 % between 2024 and 2026 and continue to drift down.
| Machine | Draw | kWh/day (24/7) | What it asks of the system |
|---|---|---|---|
| Jetson Orin NX 16 GB selected for the project's hardware lab | 10–40 W | 0.24–0.96 | A fraction of one panel — negligible, even in December |
| Mini-PC NUC-class, headless | 15–45 W | 0.4–1.1 | ~1 × 450 W panel on an annual average |
| GPU tower heavier local inference | 150–450 W | 3.6–10.8 | 2–5 panels + ~10 kWh of battery to get through the night |
The console at the top of this page already lists it as just another load: “local AI server — your memory, offline”. It is the most important number on this page: a single 450 W panel produces more than 1 kWh per day on average, even in a northern climate — enough to run your memory 24/7, year-round.
Energy autonomy and local memory are the same project: nothing that is yours should depend on a server you don't control. Discover the local memory →
On paper, a wind turbine completes solar — wind blows at night and in winter. In practice, small residential wind almost always disappoints: below a 10 m mast the wind is turbulent and weak, real output rarely matches the brochure, and the moving parts freeze, wear out and demand maintenance. Real exceptions: coastline, wide open plain, a tall mast. On a wooded lot, put that money into more panels and battery instead.
If the land has a stream with year-round flow and drop, micro-hydro is the best off-grid source there is: it produces 24 hours a day, at night and in December alike. Even a steady 500 W = 12 kWh per day — as much as the entire small-house profile above. A Pelton or turgo turbine and its penstock often cost less than a big battery bank.
A year-round stream is not a romantic detail — it's a purchase criterion. See the LAND Buy page →

The grid was a 20th-century miracle. The 21st-century miracle is that you don't need it. With panels, batteries, and a quiet inverter humming in a closet, a small piece of land can run its own life forever — as long as the sun keeps rising.
Energy is the breath of the sanctuary.
