Sizing Your System: A Mobile Solar Primer
Before you even look at a solar panel, you need to understand your power consumption. This isn’t about complex electrical engineering; it’s a simple audit. For a few days, track every single thing you use that requires electricity, from your phone charger to your water pump and refrigerator.
Most people drastically underestimate their daily power needs. They remember the big items, like a laptop or a fan, but forget the "phantom loads" from things left plugged in or the constant, low draw of a propane detector. The goal is to calculate your total daily watt-hours (Wh). A device’s wattage multiplied by the hours you use it equals its watt-hours. Add everything up, and you have your target number.
Once you know your daily watt-hour usage, you can size your battery bank. Your batteries are your power reservoir; the panels are just for refilling it. A good rule of thumb is to have enough battery capacity to last two to three days without any sun. So, if you use 1,000 Wh per day, you’ll want a battery bank of at least 2,000-3,000 Wh. This buffer is what separates a comfortable off-grid experience from a stressful one where you’re constantly checking the forecast.
Finally, your solar array (the panels) must be large enough to replenish that daily usage. In ideal sunny conditions, a 400-watt solar array might produce around 1,600 Wh in a day (400W x 4 peak sun hours). This is a rough estimate that changes with location, season, and weather. Always oversize your solar array; you will never regret having too much power, but you will always regret having too little.
Renogy 400W RV Kit: A Versatile Starting Point
This Renogy 400W solar starter kit generates up to 1600Wh daily and is ideal for RVs, boats, and off-grid systems. It includes four 100W monocrystalline panels with a durable aluminum frame and a 40A MPPT charge controller for optimized battery protection.
Renogy has become the go-to for many DIY builders, and for good reason. Their 400W RV kit is the sweet spot for a huge range of mobile rigs, from weekend campervans to full-time fifth wheels with modest power needs. It typically includes four 100W panels, a charge controller, all the necessary wiring, and mounting brackets.
This kit is a fantastic entry point because it’s both capable and expandable. Four hundred watts is enough to keep a well-sized battery bank topped off while running essentials like a 12V fridge, lights, fans, and charging electronics. If you find you need more power down the road, you can often add more panels to the system, provided your charge controller can handle the extra input.
The real value here is in the balance of cost, performance, and simplicity. It takes the guesswork out of matching components, which can be a major hurdle for first-timers. For a couple living in a skoolie or a solo traveler in a van, this system provides a solid foundation for comfortable off-grid living without a massive initial investment.

Comparing Rigid vs. Flexible Solar Panels
Choosing the type of panel is a fundamental decision with significant tradeoffs. Most kits use rigid panels, which are essentially glass-and-aluminum sandwiches. They are the workhorses of the industry for a reason. They are more durable, more efficient per square foot, and generally have a longer lifespan. The air gap created when you mount them on a roof also helps with cooling, which improves performance.
Flexible panels, on the other hand, are incredibly lightweight and low-profile. This makes them the obvious choice for curved roofs on vans like a Sprinter or for situations where stealth is a priority. You can often glue them directly to the roof, creating an installation that is almost invisible from the ground.
However, that stealth and convenience come at a cost. Flexible panels are less durable; a stray tree branch that a rigid panel would shrug off could easily damage one. They also tend to degrade faster, especially when glued directly to a roof surface where heat can build up and reduce both their efficiency and lifespan. There’s no single right answer. Choose rigid panels for durability and maximum power on a flat roof; choose flexible panels for stealth, weight savings, or curved surfaces, and accept the shorter lifespan.
Ultimately, the best solar kit is the one that reliably meets your daily needs without forcing you to constantly worry about power. Start with an honest assessment of your lifestyle, be realistic about your consumption, and invest in a quality system that gives you the freedom to unplug and stay unplugged.
