Off-Grid Solar Power for Preppers: Generators, Systems & What to Expect
When the grid fails — and if you’ve been paying attention to the news over the last several years, you know it’s a matter of when, not if — your ability to generate your own electricity is the difference between inconvenience and crisis. I’ve been living partially off-grid on our homestead in rural Idaho for over a decade, and I’ve watched neighbors scramble during every major winter storm while we kept the lights on, the well pump running, and the chest freezer sealed.
Off-grid solar power is not a luxury for preppers. It is infrastructure. And like all infrastructure, it rewards people who understand how it works before they spend money on it.
This guide covers everything you need to know to plan a legitimate off-grid solar setup: what the system actually is and how it works, what an off-grid solar generator does (and doesn’t do), how to evaluate the best off-grid solar power system for your specific situation, and what real-world costs look like in 2026. I’ll also cover the prepper-specific considerations that most mainstream solar guides skip entirely — EMP hardening, fuel independence, redundancy planning, and realistic grid-down scenarios.
Bottom Line Up Front
- Off-grid solar power is a complete system — panels, charge controller, battery bank, inverter — not just panels on a roof. Misunderstanding this leads to expensive, underperforming setups.
- An off-grid solar generator (portable power station) is useful for short outages and portability, but it is not a substitute for a permanent whole-home system.
- The best off-grid solar power system for preppers includes 3–5 days of battery autonomy, a backup generator input, and surge capacity for motor loads like pumps and refrigerators.
- Expect to spend $8,000–$20,000 for a capable DIY homestead system, or $18,000–$45,000 installed, depending on size and location.
What Is Off-Grid Solar Power?
Off-grid solar power is an electricity generation and storage system that operates completely independently from the utility grid. Unlike grid-tied solar (which sends surplus power back to your utility company and depends on that grid to function), an off-grid system is self-contained. When the utility grid fails, your off-grid system keeps running. When the utility grid doesn’t exist — as is the case for many rural homesteads — off-grid solar is the primary power infrastructure.
A complete off-grid solar power system has four core components:
1. Solar Panels (PV Array)
Solar panels convert sunlight into direct current (DC) electricity. In 2026, the dominant technology is monocrystalline PERC and TOPCon panels, which deliver 21–23% conversion efficiency. Older polycrystalline panels (16–17% efficiency) are increasingly difficult to justify given that price differences have largely disappeared.
Panel sizing is measured in watts (W) at standard test conditions (STC). A typical prepper or homesteader setup ranges from 1,500W to 10,000W of panel capacity, depending on energy needs. Real-world output is always lower than STC ratings — plan for 70–80% of nameplate capacity on a clear, mild day, and significantly less in winter or overcast conditions.
2. Charge Controller
The charge controller sits between your panels and your battery bank, regulating the voltage and current flowing into the batteries to prevent overcharging and optimize charging efficiency. There are two types:
- PWM (Pulse Width Modulation): Older, cheaper, less efficient — appropriate only for small, simple systems under 200W.
- MPPT (Maximum Power Point Tracking): The current standard for any serious off-grid system. MPPT controllers track the optimal operating point of the panel array and can be 20–30% more efficient than PWM, especially in cold weather or partial shading. Brands like Victron SmartSolar, Renogy Rover, and Outback FlexMax are well-regarded.
For a prepper system, always specify MPPT.
3. Battery Bank
Your battery bank stores the electricity your panels generate during the day so you can use it at night or during cloudy periods. Battery technology is the most consequential choice in an off-grid build, and it has changed dramatically in the past decade.
Lithium Iron Phosphate (LFP / LiFePO4) batteries have effectively replaced lead-acid as the serious choice for off-grid systems. Here’s why:
| Metric | LFP (Lithium Iron Phosphate) | Flooded Lead-Acid | AGM Lead-Acid |
|---|---|---|---|
| Usable capacity (DoD) | 80–100% | 50% | 50–60% |
| Cycle life (to 80% capacity) | 3,000–6,000+ cycles | 400–700 cycles | 600–1,200 cycles |
| Weight | Light (roughly half of lead-acid per kWh) | Heavy | Heavy |
| Maintenance | None | Regular watering | Minimal |
| Temperature tolerance | Good (-4°F to 131°F operational) | Poor in cold | Moderate |
| Cost per usable kWh (2026) | $250–$450 | $200–$350 | $300–$500 |
The math is clear: LFP costs more upfront but delivers 5–10x the cycle life, which means a dramatically lower total cost of ownership over a 10–15 year off-grid system life. For a prepper, the no-maintenance, no-outgassing profile of LFP is also tactically important — you don’t want to manage battery watering schedules during a grid-down scenario.
System voltage is typically 12V (small systems), 24V (medium), or 48V (recommended for systems above 2kWh). Higher voltage reduces wire losses and allows use of smaller, cheaper wire runs.
4. Inverter (and Inverter/Charger)
Your panels and batteries operate on DC power. Most household appliances operate on 120V or 240V AC. The inverter converts DC to AC. For a serious off-grid system, you want a pure sine wave inverter — modified sine wave units cause problems with sensitive electronics, some motor loads, and many modern appliances.
Most serious off-grid systems now use an inverter/charger, which combines the inverter function with a battery charger that can accept input from a generator or shore power. Brands like Victron MultiPlus, Outback Radian, and Sol-Ark are common in professional installations. Sol-Ark’s all-in-one units (8K and 15K models) have become popular in the DIY community because they integrate the charge controller, inverter, and grid/generator input in one enclosure.
Inverter sizing matters for surge capacity — the brief spike in power a motor requires when starting. A well pump drawing 800W continuous may surge to 2,400W at startup. Size your inverter to handle the largest surge load you anticipate, not just your average load. Most quality inverters can handle 2–3x their rated continuous output as a surge.
Off-Grid Solar Generator: Portable vs. Permanent
“Off-grid solar generator” is a phrase that gets used for two very different things, and confusing them is one of the most common (and costly) planning mistakes preppers make.
Portable Solar Power Stations (Consumer “Solar Generators”)
Products like the EcoFlow Delta Pro, Bluetti AC300, and Jackery Explorer series are often marketed as “solar generators.” They are portable power stations — self-contained units with built-in batteries, inverters, and charge controllers that can accept input from folding solar panels.
For what they are, these units are genuinely excellent. A unit like the EcoFlow Delta Pro offers 3.6kWh of capacity (expandable), a 3,600W inverter, and fast solar charging input. For a prepper context, portable solar generators shine in:
- 72-hour emergency backup for critical loads (lights, communication, medical devices, phone charging)
- Bug-out or retreat scenarios where you need power at a location without a permanent system
- Supplemental power for a cabin, garage, or outbuilding not connected to the main off-grid system
- Grid-down bridging while a permanent system is being installed or repaired
What they cannot do, practically speaking, is power a whole home continuously. A unit with 3.6kWh of usable storage will run a typical homestead with refrigerator, well pump, and basic lighting for less than a day. And recharging from portable solar panels (100–400W) takes many hours of good sun per kWh of storage. An off-grid solar generator is a complement to a permanent system, not a replacement for it.
Permanent Off-Grid Solar Systems
A permanent off-grid system is fixed-mounted panels, a proper battery bank sized for days of autonomy, and a whole-home inverter. This is what powers a homestead day in and day out, indefinitely. You can read much more detail in our off-grid power system guide and our roundup of best off-grid solar systems.
The practical distinction for a prepper: invest in a permanent system as your primary infrastructure, then add one or two portable solar generators for flexibility and redundancy. The portable units become your mobile backup when the permanent system is down for maintenance, your camping and retreat power source, and your “run to the garage in an emergency” option.
Best Off-Grid Solar Power System: What Components Actually Matter
When someone asks me to recommend the best off-grid solar power system, my first question is always: “What does your load audit say?” Because the best system is the one matched to your actual needs — not the most expensive, not the most talked-about brand, and definitely not whatever a YouTube influencer got sponsored to feature.
That said, there are component-level choices that consistently separate high-performing systems from disappointing ones. Here’s the framework I use when helping families in our community plan their builds.
Panel Selection: Go Monocrystalline, Size Aggressively
In 2026, monocrystalline panels are the only serious choice for off-grid installations. PERC (Passivated Emitter and Rear Cell) panels from brands like Jinko, LONGi, Canadian Solar, and REC Group deliver 400–580W per panel at 21–23% efficiency. TOPCon panels push into the 24%+ range.
Size your array at 120–150% of your calculated daily energy need. If your load audit shows 6 kWh/day and your location averages 5 peak sun hours, you theoretically need 1,200W of panels. In practice, install 1,800W to account for panel aging (0.5% per year efficiency loss is typical), seasonal variation, partial shading, and soiling losses. Over-paneling is almost always cheaper than under-paneling once you factor in the cost of later expansion.
For our complete breakdown of panel specifications, installation angles, and what to watch for in low-quality panel documentation, see our guide to solar panels for off-grid living.
Charge Controller: MPPT, Sized for Expansion
Specify your MPPT charge controller to handle your eventual panel capacity, not just your current panels. Charge controllers are relatively inexpensive compared to panels and batteries — don’t pinch pennies here and then discover your 60A controller can’t accept the additional panels you’re adding in year two.
Key specifications to match: input voltage range (must exceed your panel array’s Voc at lowest expected temperature), maximum input power (in watts), and output current rating (in amps at your battery voltage).
Battery Bank: LFP, 3–5 Days of Autonomy
This is where preppers should be most deliberate. The mainstream home solar industry often designs for 1–2 days of battery autonomy because grid backup is always there if needed. Preppers don’t have that luxury.
Size your battery bank for 3–5 days of your average daily consumption without any solar input. This is your grid-down resilience window. In a real emergency — extended winter storm, grid attack, supply chain disruption — you need enough storage to outlast the acute phase of the event while you activate backup power sources.
At 6 kWh/day average load, 3 days of autonomy = 18 kWh of usable storage. With LFP at 80–90% usable depth of discharge, you need approximately 20–22.5 kWh of nameplate battery capacity. In 2026, that might be five 48V/100Ah LFP batteries (24 kWh nominal, ~21.6 kWh usable) at roughly $7,000–$10,000 for quality units.
Inverter/Charger: Pure Sine Wave, Generator-Ready
Specify a pure sine wave inverter/charger with generator input capability. The generator input is critical for prepper applications — when you have 10 consecutive cloudy days and the batteries are at 20%, you need to be able to start a backup generator and recover. Systems without this integration require awkward workarounds.
Size the inverter for your largest surge load plus a healthy buffer. If your well pump is a 1HP unit (roughly 750W continuous, 2,200W surge), a 3,500W inverter would handle it with room to run lighting and a refrigerator simultaneously.
The Best Off-Grid Solar Power System in Practice
When all four components are correctly matched and sized, the best off-grid solar power system for a prepper household typically looks like this in 2026:
- 4–8kW monocrystalline array (10–20 panels at 400W each), ground-mounted or roof-mounted at optimal tilt for latitude
- 48V LFP battery bank with 15–30 kWh of usable storage (3–5 days autonomy)
- MPPT charge controller rated at 60–100A, 150V+ input voltage
- 3,500–8,000W pure sine wave inverter/charger with generator input, transfer switch built in
- Backup generator (propane or dual-fuel preferred — more on this below)
- System monitoring with remote access via app (Victron VRM, Sol-Ark monitoring, etc.)
Best Off-Grid Solar System: Sizing Your Build from Scratch
If you haven’t yet run a load audit, this section will walk you through the process. Sizing the best off-grid solar system for your property is not difficult — but skipping it is the single most reliable way to build a system you’ll be frustrated with.
Step 1: Inventory Your Loads
List every electrical device you expect to run regularly. For each device, note:
- Wattage (check the label or nameplate; for motors, note both running and startup wattage)
- Hours per day of expected use
Multiply watts × hours = watt-hours (Wh) per day for each device. Sum them all. This is your daily energy consumption target.
Common homestead loads (approximate):
| Appliance | Running Watts | Hours/Day | Wh/Day |
|---|---|---|---|
| Chest freezer (15 cu ft) | 100W | 8 (duty cycle) | 800 |
| Refrigerator (20 cu ft) | 150W | 8 (duty cycle) | 1,200 |
| Well pump (1/2 HP) | 500W | 1 | 500 |
| LED lighting (whole house) | 150W | 5 | 750 |
| Laptop + phone charging | 100W | 4 | 400 |
| Washing machine (efficient) | 500W | 0.5 | 250 |
| Basic homestead total | — | — | ~3,900 Wh/day |
Add items specific to your situation: workshop tools, water heater, electric vehicle charger, HVAC, irrigation pumps. A moderate homestead often lands at 5–10 kWh/day; a larger property with more loads can run 15–20 kWh/day.
Step 2: Calculate Solar Array Size
Find your location’s average peak sun hours (PSH) from NREL’s PVWatts tool — this is the number of hours per day when sunlight is intense enough to drive your panels at full rated output. In the continental U.S., this ranges from roughly 3.5 PSH (Pacific Northwest, winter) to 7.0 PSH (Southwest desert).
Array size needed (W) = Daily consumption (Wh) ÷ PSH × system efficiency factor (0.75–0.80)
Example: 6,000 Wh ÷ 5 PSH ÷ 0.77 = 1,558W minimum. Install 2,000–2,400W for weather margin.
Step 3: Size Your Battery Bank
Battery capacity (Wh) = Daily consumption × days of autonomy ÷ usable DoD
Example: 6,000 Wh × 4 days ÷ 0.85 (LFP DoD) = 28,235 Wh ≈ 30 kWh nominal capacity.
Step 4: Match Charge Controller and Inverter
Charge controller amperage = Array wattage ÷ Battery bank voltage. A 3,000W array at 48V needs at least a 62.5A controller — specify a 80A unit for headroom.
Inverter VA rating should exceed your largest simultaneous load with surge margin. For 3,500W peak simultaneous load, a 5,000W (5kVA) inverter/charger provides adequate buffer.
Step 5: Add Backup Generator
Specify a generator sized to run your critical loads AND charge your battery bank simultaneously. A 6,500–10,000W generator covers most homestead applications. Propane or dual-fuel is preferred for preppers: propane stores indefinitely without treatment, unlike gasoline (which degrades in 6–12 months). Natural gas is viable if you have a large fixed tank.
Real Costs: What to Expect in 2026
Let me give you honest numbers, not best-case marketing figures. These are based on real builds I’ve seen completed or advised on in 2025–2026.
Small Prepper System (2–3 kWh/day, cabin or apartment-backup)
- 1,500W monocrystalline panels: $600–$1,200
- 10 kWh LFP battery bank (48V/200Ah): $2,500–$4,500
- 60A MPPT charge controller: $250–$500
- 3,000W pure sine wave inverter/charger: $600–$1,200
- Wiring, breakers, mounting hardware: $400–$800
- DIY total: $4,350–$8,200
- Installed by contractor: add $3,000–$7,000 for labor and permitting
Medium Homestead System (6–8 kWh/day, family of four)
- 4,000W panel array: $2,000–$4,000
- 20 kWh LFP battery bank: $5,000–$9,000
- 80A MPPT charge controller: $400–$700
- 5,000W inverter/charger (Sol-Ark 5K or similar): $1,500–$2,500
- Wiring, panels, mounting, surge protection: $1,500–$3,000
- Backup propane generator (8,000W): $1,500–$2,500
- DIY total: $11,900–$21,700
- Installed: $22,000–$38,000
Large Homestead System (12–15 kWh/day, full self-sufficiency)
- 8,000W panel array: $4,000–$8,000
- 30–40 kWh LFP battery bank: $9,000–$16,000
- 100A MPPT charge controller(s): $700–$1,200
- 8,000–15,000W inverter/charger: $2,500–$5,000
- Balance of system (wiring, breakers, battery management, monitoring): $2,500–$5,000
- Backup generator: $2,000–$4,000
- DIY total: $20,700–$39,200
- Installed: $35,000–$65,000+
These ranges are wide because location, labor market, permitting complexity, and component brand choices all significantly affect final cost. Urban and suburban installs trend toward the high end; rural DIY installs can come in well below the midpoint.
Prepper-Specific Considerations for Off-Grid Solar
This is where most mainstream solar guides stop being useful and where I want to focus specifically for those of you thinking about long-term grid independence.
Resilience vs. Optimization
The mainstream solar industry optimizes for grid-tied economics: maximize self-consumption, minimize grid draw, maximize feed-in tariff credits. Preppers optimize for resilience: maximum autonomy, longest possible independent operation, fastest recovery from any system failure.
This produces different design choices:
- Autonomy over export: Size for 4–5 days of storage rather than the minimal battery banks popular in grid-tied hybrid systems.
- Backup redundancy: Install a second charge controller path from a different panel sub-array, so a single controller failure doesn’t kill your charging.
- Generator integration: Hard-wire a generator input to your inverter/charger. Don’t rely on extension cords and manual transfer switches in an emergency.
- Critical load panel: Wire your most essential loads (well pump, refrigerator, medical devices, communication) on a dedicated sub-panel that the inverter/charger powers directly. This keeps critical systems alive even if something trips the main panel.
EMP Hardening Considerations
Electromagnetic pulse (EMP) is a real concern in serious preparedness planning. An EMP event — whether from a nuclear detonation at altitude, a solar coronal mass ejection, or a targeted directed-energy weapon — could destroy unprotected electronics including solar charge controllers, inverter electronics, and battery management systems.
Full EMP hardening of an off-grid system is expensive and complex, but there are reasonable precautions:
- Keep spare controllers in a Faraday cage (a metal garbage can with a tight-fitting metal lid and an insulated lining works for basic protection). At minimum, store a spare PWM charge controller this way — it’s cheaper than an MPPT controller and can run a reduced system in an emergency.
- Older, simpler electronics are more survivable. A mechanical transfer switch survives where a digital one might not.
- Batteries are generally EMP-survivable. LFP batteries themselves don’t have sensitive electronics in the cells — the Battery Management System (BMS) is the vulnerable component.
- Panel strings without electronics in the circuit (just panels and wire) are very EMP-resistant. The energy conversion electronics are the weak point.
This is a nuanced topic — for a deeper dive, see resources from the EMP Task Force on National and Homeland Security.
Fuel Independence and Long-Term Sustainability
Solar panels are the closest thing to “free fuel” that exists in practical preparedness planning. Once installed, a solar array generates power with no ongoing fuel cost and minimal maintenance (annual cleaning, periodic connection inspection) for 25–30 years.
This is fundamentally different from generator-only preparedness strategies, which depend on continuous fuel resupply. Solar-first, generator-backup is the correct architecture for serious long-term grid independence.
When specifying your backup generator for a prepper off-grid system:
- Propane: Stores indefinitely with proper maintenance, widely available, cleaner-burning than gasoline.
- Dual-fuel: Gasoline + propane flexibility maximizes your fuel sourcing options.
- Natural gas with a large tank: Reliable but limits portability and depends on utility supply.
- Diesel: Excellent energy density, stores 18–24 months with stabilizer, runs efficient generators, but requires more maintenance than propane.
Monitoring and Fault Detection
In a grid-down scenario, you need to know your system’s state without internet connectivity. Specify a system with local monitoring capability — a display on the inverter/charger or charge controller that shows battery state of charge, current generation, current consumption, and any fault codes. Remote app-based monitoring is a convenience in normal times; local displays are critical during emergencies.
Brands like Victron have excellent local Bluetooth monitoring via their VictronConnect app (works on local Bluetooth without internet). Sol-Ark units have physical displays with comprehensive status readouts.
A Note on Alternative Approaches
Not every prepper goes the standard solar route, and that’s worth acknowledging. Some are attracted to unconventional DIY power concepts — systems that claim to generate energy from different principles or use interesting electromagnetic or mechanical approaches.
For buyers interested in unconventional DIY power approaches, Home Power Shield offers a different angle on home power generation — backed by a 60-day refund policy, which is worth noting before you invest time in evaluating it. You can read a detailed breakdown in our Home Power Shield review.
For a comprehensive comparison of all the major off-grid power approaches — solar, wind, micro-hydro, and unconventional alternatives — see our complete off-grid power guide. And for a specific look at how the Energy Revolution System positions itself against conventional solar, that review covers the specs and claims in detail.
Getting Started: Your First Steps
If you’re convinced off-grid solar power is the right investment and you’re ready to start planning, here’s the sequence I recommend:
- Run a load audit. Every appliance, every circuit, estimated hours of use. This is not optional — it is the foundation of every other decision.
- Find your peak sun hours. Use NREL’s PVWatts calculator for your specific address.
- Set your autonomy target. For preppers: minimum 3 days, ideally 5 days.
- Get bids from local installers — even if you plan to DIY. Installers know local permitting requirements, rebate programs, and utility interconnection rules (even if you’re going fully off-grid, you may still need a permit).
- Read manufacturer specs, not just marketing copy. For panels: check Pmax, Voc, Vmp, Isc, temperature coefficients. For batteries: check cycle life at your target DoD, operating temperature range, BMS protections. For inverters: check continuous output, surge rating, input voltage range, and generator compatibility.
- Start small if budget is the constraint. A well-designed 2kWh backup system that covers your critical loads is more useful than a 10kWh system you can’t afford to build correctly.

Frequently Asked Questions
What is off-grid solar power?
Off-grid solar power is a system that generates electricity from solar panels without connection to the utility grid. It typically includes solar panels, a charge controller, battery bank, and inverter to power a home or property independently. Unlike grid-tied solar, an off-grid system must store all its own energy for use at night or during cloudy periods.
What is the best off-grid solar power system for preppers?
The best system depends on your power needs and budget. For preppers, a system with 4–8kW of monocrystalline panels, an MPPT charge controller, a 15–30kWh lithium iron phosphate (LFP) battery bank, and a hybrid inverter/charger with generator input provides the most resilient setup. Size for at least 3–5 days of autonomy without sun — more than the 1–2 days typical grid-tied hybrid systems target.
What is an off-grid solar generator?
An off-grid solar generator is typically a portable power station that combines a battery, inverter, and charge controller in a single unit, designed to charge from folding solar panels. Units like the EcoFlow Delta Pro, Bluetti AC300, and Jackery Explorer series fall in this category. They excel at portable backup power and supplemental loads but don’t replace a permanent whole-home off-grid solar system.
How long do off-grid solar systems last?
Quality solar panels carry 25–30 year performance warranties and degrade at roughly 0.5% per year. LFP batteries last 3,000–6,000+ cycles to 80% capacity, which translates to 10–20 years depending on usage pattern. Charge controllers and inverters typically last 10–15 years. With proper maintenance and component replacement as needed, an off-grid solar system can realistically operate for 25+ years.
What is the best off-grid solar system available?
The best solar system combines high-efficiency monocrystalline PERC or TOPCon panels, an MPPT charge controller sized for the array, LFP batteries with a quality BMS, and a pure sine wave inverter/charger with generator input capability. Size to 120–150% of your daily energy needs for weather buffer. For preppers, build in 3–5 days of battery autonomy. Victron, Sol-Ark, and Outback are consistently reliable component brands; the “best” system is the one that’s correctly sized and installed for your specific location and load.
Does off-grid solar work in winter or cloudy climates?
Yes, but output is significantly reduced. In cloudy climates like the Pacific Northwest, a system sized for 4 peak sun hours in summer might see only 1.5–2.5 hours in December. This is why battery bank sizing for multiple days of autonomy, and a backup generator, are both essential in off-grid systems outside the Sun Belt. Panel array oversizing also helps — a larger array produces meaningfully more power even on cloudy days.
How much does a prepper off-grid solar system cost?
A practical prepper system ranges from approximately $4,000–$8,000 DIY for a small backup system (10 kWh storage, 1,500W panels), to $12,000–$22,000 DIY for a medium homestead system (20 kWh storage, 4kW panels), to $20,000–$40,000 DIY for a large self-sufficient system (30–40 kWh storage, 8kW panels). Professionally installed systems typically cost 1.5–2x the DIY cost due to labor and permitting.
Key Takeaways
- Off-grid solar power is a complete system — panels, charge controller, battery bank, and inverter working together. Each component must be correctly sized and matched to the others.
- Portable off-grid solar generators serve a different role than permanent systems. Use them for portability, short-term backup, and supplemental power — not as a whole-home solution.
- The best off-grid solar power system for preppers prioritizes autonomy (3–5 days of battery storage), generator integration for backup, and component quality over price-cutting.
- The best off-grid solar system combines monocrystalline PERC or TOPCon panels, MPPT charge control, LFP batteries, and a pure sine wave inverter/charger. Size to 120–150% of daily needs.
- LFP batteries are the correct choice for any serious prepper off-grid system — the cycle life, DoD, and maintenance-free operation are unmatched by lead-acid alternatives.
- Real costs for a competent system range from $12,000–$22,000 DIY for a medium homestead — a significant investment that pays for itself in energy independence, not just utility savings.
- EMP hardening is worth addressing with Faraday-protected spare components, not wholesale system redesign.
- Solar-first, generator-backup is the right preparedness architecture. Fuel independence is the strategic advantage solar provides over generator-only approaches.
