FROM THE DESK
My neighbor installed a small solar panel on his shed roof. Not a full home system. Just a 100-watt panel, a charge controller, and a battery. Total cost: about $300. During our last outage, he charged phones, ran lights, and powered a fan. He built the whole thing from a YouTube tutorial in an afternoon.
Here's what I've got today:
THE BRIEF
Solar Power for Beginners: Off-Grid Basics That Work
We covered portable power stations in Issue 21 and solar chargers in Issue 27. This week is the next step: a basic solar setup that provides meaningful backup power without the $20,000 price tag of a full home solar installation.
A beginner solar system has four components: a solar panel that converts sunlight to electricity, a charge controller that regulates the flow so you don't damage your battery, a battery that stores the energy, and an inverter that converts the battery's DC power to the AC power your household devices use.
For emergency preparedness, you don't need to power your whole house. You need to power the essentials: lights, phone charging, a radio, a fan, and maybe a small refrigerator. A 100 to 200 watt panel paired with a 100 amp-hour lithium battery handles all of these with room to spare.
Here's the math. A 100-watt panel produces roughly 400 to 500 watt-hours of energy per day (5 hours of good sun times 80 to 100 watts actual output). A phone charge uses about 15 watt-hours. An LED light uses about 10 watts per hour. A small fan uses 20 to 40 watts per hour. So a single panel produces enough daily energy to charge five phones, run lights all evening, and power a fan for several hours.
Pre-built portable power stations (Goal Zero, Jackery, Bluetti, EcoFlow) combine the battery, charge controller, and inverter into one unit. They're more expensive per watt-hour than DIY, but they require zero technical knowledge. Plug in the solar panel, plug in your devices. That's it.
DIY systems are cheaper and more flexible. A Renogy 100W panel (about $85), a 30A charge controller (about $33), a 100Ah LiFePO4 battery (roughly $250 to $280), and a 1000W pure sine wave inverter (about $100 to $120) give you a capable system for roughly $470 to $520 total. The learning curve is manageable. The wiring is straightforward. And once built, you can expand it by adding panels or batteries.
Location matters. Panels need direct sunlight, ideally south-facing in the Northern Hemisphere. Even a ground-level panel propped against a wall works. Shade reduces output dramatically, so find the sunniest spot available.
One caution: solar doesn't work at night, and cloudy days reduce output significantly. Battery storage is what bridges the gap. Size your battery for the hours you need power when the sun isn't shining.
ONE THING THIS WEEK
Calculate your essential power needs.
List the devices you'd want to power in an outage: phones, lights, fan, radio. Look up the wattage of each (usually on the device or charger). Add them up. That total tells you how big a solar system you actually need. Most people are surprised how small it is.
ON THE RADAR
Michigan Cyclospora Cases Top 6,500 As Source Remains Unconfirmed
Michigan's cyclosporiasis outbreak has grown to more than 6,500 confirmed cases this week, more than doubling in the last ten days, with state and federal investigators focusing on iceberg lettuce as the likely source. That's more than double from the last time this was on the radar. The outbreak spans at least 34 states nationally, and the FDA has not yet pinned down the exact supply chain link.
This is shaping up as one of the largest foodborne outbreaks in years, and tracing it has already taken weeks. Rinsing produce does not reliably kill Cyclospora, since the parasite needs time in the environment to become infectious, part of why sourcing has been so hard to pin down. Buying whole heads of lettuce from a known farm, or growing your own greens, sidesteps supply chains you cannot personally audit.

LESSON FROM: EJ SNYDER
EJ Snyder spent 25 years in the Army and became a legend on Naked and Afraid for his ability to improvise solutions from nothing. While solar panels weren't part of his jungle survival toolkit, his philosophy applies directly: understand the resource available to you and build systems to capture it efficiently.
Snyder's approach to any resource, whether it's food in the wild or energy from the sun, follows the same pattern: assess what's available, build the simplest capture system that works, and store the surplus for when production stops. A solar panel captures energy when the sun shines. A battery stores it for when it doesn't. That's the entire concept, and it mirrors how survival works in any environment.
WHAT'S HAPPENING
West Virginia Flash Flooding Kills At Least Seven, Including a 3-Year-Old
Catastrophic flash flooding tore through West Virginia's Ohio Valley region this week, ripping a wall of floodwater through a Wheeling apartment building and pushing the death toll to at least seven. Governor Jim Justice declared a state of emergency as rescue crews continued searching for residents still unaccounted for, with one victim's body recovered near a dam.
Flash floods in mountainous terrain like West Virginia's can turn a dry creek bed into a fatal current within minutes, often with almost no warning. A charged NOAA weather radio, a plan to move to higher ground immediately rather than just upstairs, and a hard rule against driving through flooded roads matter most here. Most flood deaths happen in vehicles.

WHAT WE'RE RECOMMENDING
We've been using this panel as part of our DIY solar setup for about six months. It's a rigid panel (not folding) that mounts on a roof, ground stand, or just props against a south-facing wall. Output is consistently 80 to 100 watts in full sun, which matches the rated capacity well.
Build quality is solid. Aluminum frame, tempered glass, and weatherproof junction box. It's survived rain, wind, and a few accidental drops without issue. The included MC4 connectors make wiring to a charge controller straightforward.
We pair it with a Renogy Wanderer 30A charge controller and a 100Ah LiFePO4 battery. The whole system charges the battery from empty in about one and a half sunny days. That's enough stored energy to run lights and charge phones for three to four days without additional sun. About $85 for the panel alone.
Budget alternative: A 50W folding solar panel ($60). Half the output, but portable and good enough for phone and battery bank charging. A reasonable first step before committing to a larger system.
OVERRATED / UNDERRATED
Overrated: Full home solar installations for emergency preparedness. They're excellent investments for daily energy savings, but most grid-tied systems shut off during outages (for lineworker safety) unless you add an expensive battery backup. A $500 portable system provides emergency power without the $20,000 commitment.
Underrated: LiFePO4 batteries. They cost more upfront than lead-acid, but they last 10 to 15 years (versus 3 to 5), weigh half as much, and can be discharged much deeper without damage. For a system you might not use often, longevity matters more than upfront cost.

PS: My neighbor's $300 solar setup isn't going to power his air conditioning. But during the last outage, his house had cold drinks and charged phones. Sometimes "enough" is more than enough.
