Portable power station vs solar generator comparison showing standalone battery unit next to solar generator with foldable solar panels

Portable Power Station vs Solar Generator: 5 Key Differences (2025)

Most buyers assume “solar generator” and “portable power station” are the same thing—but after testing eight units over six months of off-grid camping, I found critical differences that affect cost, usability, and long-term value. A portable power station is 40% cheaper upfront, but a solar generator pays for itself in 18 months if you’re off-grid […]

MPPT vs PWM Charge Controller: Efficiency Test Results 2026

MPPT charge controllers deliver 95-98% efficiency vs PWM’s 75-80% in ideal conditions. Real-world testing shows MPPT gains 22% more power in cold weather (below 10°C), 15% in moderate temps (10-25°C), and only 8-12% in hot climates (above 30°C). For systems under 200W with voltage-matched panels, PWM costs $100+ less with minimal performance difference. The difference

Solar Panel Not Producing Enough Power? 8 Reasons Why (+ Fixes)

Solar panels producing 30-50% below expected output usually indicates dirt buildup, partial shade, or temperature effects—not panel failure. A 100W panel rated for 100W at 77°F will only produce 70-80W on a 95°F day, and that’s normal. The fix depends on whether output dropped suddenly (usually fixable) or gradually (age-related degradation). Here are the eight

How Long Will a Solar Generator Run a Refrigerator? (Runtime Calculator)

A 1000Wh solar generator runs a standard refrigerator (150W average) for 6-8 hours on battery alone. Add solar panels generating 200W in peak sun, and runtime extends to 12-24+ hours depending on sunlight. The key is matching generator capacity to your fridge’s actual consumption—not just nameplate watts.Here’s how to calculate exact runtime for your setup,

Do Solar Panels Work in Winter? (Snow + Cold Weather Performance)

Yes, solar panels work in winter. Cold temperatures actually improve efficiency—panels convert sunlight better at 32°F than 77°F. The problem isn’t cold. It’s short days, low sun angle, and snow coverage blocking panels.Here’s what actually happens in winter and what you need to know.
