Trail cameras, feeders, fans, and lights — sized around how hunters actually use a blind: hard on the weekend, empty all week. That empty time is free power most calculators ignore.
Five quick steps. We size your panel, battery, and cost — using logic built for hunters, not full-time cabins.
This sets your baseline load before cameras or appliances are added.
Cellular cameras need constant power — this is the load most calculators skip entirely.
Select everything you'll actually power. Per-sit items are converted to a daily average automatically.
This is the biggest lever in the whole calculation — weekend hunters need far less solar than a full-time setup.
Size for your worst month, not your best one. We use late-season sun hours by default.

A gas generator idles at 80-100 decibels. In still, cold hunting-season air, that sound carries hundreds of yards — right through the property you're trying to hunt quietly. Mature bucks learn to pattern that noise fast, and pressured deer shift nocturnal within days.
Solar sidesteps the problem entirely: no engine, no exhaust smell, no weekly gas run. It charges in silence while you're at work, and it's already topped off by the time you climb into the stand.
Most calculators size a system as if someone's out there every single day. Weekend hunters get five free recharge days most tools never account for.
| Daily usage during hunts (100Wh × 2 sit days) | 200 Wh needed |
| 20W panel × 2.8 hrs sun × 5 weekday charging days | 280 Wh recharged |
| Result | Battery full by Wednesday ✅ |
A weekend hunter with a 20-30W panel ends up in the same position as a full-time camper running a 100W panel — because the panel isn't racing the load every single day, it's racing it two days out of seven.
2 hunt days, 5 free recharge days. Smallest system on this page.
More hunt days shrink the recharge window — step up panel size accordingly.
Trail cams and feeder run every single day. Size for the worst cloudy week, not the average one.
Solar trail cameras have become the standard way to cut human pressure on a property, since they skip the walk-in battery swaps that put your scent everywhere.
SPYPOINT Flex-S, Tactacam Reveal, and Stealth Cam models integrate a small panel on the housing.
Best for: open food plots, field edges, anywhere with direct sun most of the day.
Simple, no wiring — but a small panel struggles in deep shade.
A 10-20W panel feeding a 12V battery gives a standard camera far more reserve power.
Best for: shaded timber trails, or running several cameras off one larger battery.
More setup and wiring, but no shade penalty.
A shiny silver panel frame catches light exactly like the gear you're already careful about. Panel color, wire routing, and battery box choice all factor into how quickly a setup disappears into the landscape.
| Choice | Why it matters |
|---|---|
| Black / matte panel | Blends in, no reflection |
| Silver / glossy frame | Flashes in direct sun |
| Wires inside blind walls | Nothing crossing open ground |
| Dark, weatherproof battery box | Low profile, blends with structure |
✔ South-facing panel, away from the deer's usual approach
✔ Slightly elevated mount so no shadow sweeps across the ground
✔ Wires zip-tied to the shaded side of the tree or post
✔ Matte, dark battery box — never a bright plastic case
A single sit with a plug-in heater can cost more energy than an entire week of everything else combined.
1. Hand warmers — 0 Wh, no solar needed at all.
2. Heated seat cushion — 30 Wh/sit, easy to fit on any system.
3. Diesel/propane heater, fan only — 12 Wh/day, fuel does the heating work.
Your peak hunting window runs October through December — and sun hours quietly drop through that entire stretch. A system that works in October can fall short by the December gun season.
| State | Peak Season | Oct Sun Hrs | Dec Sun Hrs |
|---|---|---|---|
| Texas | Oct – Jan | 4.6 hrs | 4.2 hrs |
| Alabama | Oct – Jan | 4.4 hrs | 4.0 hrs |
| Iowa | Oct – Nov | 4.0 hrs | 3.4 hrs |
| Montana | Sept – Nov | 4.1 hrs | 3.6 hrs |
| Pennsylvania | Oct – Nov | 3.6 hrs | 3.0 hrs |
| Michigan | Oct – Nov | 3.4 hrs | 2.8 hrs |
| Wisconsin | Oct – Dec | 3.2 hrs | 2.7 hrs |
If your setup handles your state's December number, it handles the entire season. Northern states in particular need extra panel wattage to make up for that late-season drop.
An automatic feeder's power draw is small but constant — the kind of load that's easy to undersize because it looks trivial on paper.
| Digital timer | 2 Wh/day |
| Spin-plate motor (2× 30-sec bursts) | 5 Wh/day |
| Feeder light (optional) | 5 Wh/day |
| Total feeder load | ~12 Wh/day |
A 10W panel with a 7Ah battery covers this for under $40 total, and runs the feeder unattended for a full season.
Sun hours drop through the season. A system that works on opening weekend can fall short by late gun season.
Without one, the battery can drain back through the panel overnight and die within weeks.
A non-cellular camera can tolerate a dip. A cellular model loses connectivity and misses activity the moment power drops.
Reflective frames catch light. Black or matte panels blend in and don't flash toward bedding areas.
One 750W heater sit can outweigh an entire week of lights, cameras, and phone charging combined.
For a weekend-only setup with basic loads — lights, a fan, phone charging — a 20-30W panel is usually enough, because the panel gets five full weekdays to recharge a battery that only discharges on Saturday and Sunday. A permanent blind running cellular cameras and a feeder around the clock needs 60-100W since there's no multi-day rest window. Use the calculator above for your exact number.
Yes. A single cellular trail camera draws roughly 3-5Wh per day, and a feeder timer with a spin-plate motor draws about 12Wh per day. Combined, a 10-20W panel with a 7-20Ah battery and a basic PWM charge controller runs both unattended for a full season.
Not if you choose a black or matte-finish panel instead of a reflective silver-framed one, and route wiring along the shaded side of the structure. A static, non-reflective panel blends into the blind within a week or two — unlike a generator's noise and exhaust, which deer actively pattern.
A single cellular camera needs roughly 3-5Wh per day, which a 5-10W panel covers even on shorter fall days. Because cellular models need constant power for connectivity, pair the panel with enough battery to ride out 5-7 cloudy days rather than sizing the panel alone.
A 750W electric heater run for a two-hour sit uses about 1,500Wh, which needs roughly 300W of panels and a 150Ah battery for a single sit — expensive for solar alone. A diesel or propane heater with only a 12V fan draws about 12Wh per day, or a heated seat cushion at 30Wh per sit, both far more solar-friendly options. See our battery guide → for lithium vs. AGM sizing.
Permanent blinds with cellular cameras, a feeder, and unattended operation need continuous power rather than weekend-cycle charging. A 100W panel, 100Ah LiFePO4 battery, and MPPT charge controller sized for your area's worst-case December sun hours covers fans, lights, cameras, and a feeder around the clock. Our hunting cabin calculator → covers the full-cabin version of this same math.
A digital timer, spin-plate motor, and optional feeder light together use about 12Wh per day. A 10W panel, 7Ah battery, and a PWM charge controller handle this for under $40 total and run unattended for the season.
Yes, even on small systems. Without one, the battery can back-feed the panel at night and drain itself dead within weeks — a common failure reported by feeder owners. A basic 10A PWM controller costs about $12 and prevents this entirely.
