Off-Grid Solar Panels

At King of Generators, we’ve built our reputation on delivering reliable, high-performance power solutions you can trust. Our Off-Grid Solar Panels collection features a wide range of efficient solar panels, expandable kits, and complete off-grid systems ideal for cabins, remote living, RVs, emergency backup, and more. With high-efficiency monocrystalline and advanced PERC options designed to withstand harsh weather and long-term use, these solar solutions bring sustainable energy independence wherever you need it. Most products include robust warranties for materials, workmanship, and long-term performance, so you can invest in renewable power with confidence.

Our Product Category

We stock a diverse range of solar panel solutions tailored to specific energy loads and installation environments. From massive whole-home systems to portable units for weekend getaways, our collection features top-tier brands like Sungold Power, EcoFlow, Nature Power, ACOPOWER, and many more, each engineered for reliable, high-performance energy.

Understanding Capacity

The capability of these kits is measured in watts (W) and kilowatt-hours (kWh). Our inventory ranges from substantial 5,000W setups to massive 20,000W systems.

• 5,000W Systems: Ideal for smaller cabins or energy-conscious homes, often featuring setups like the Sungold Power SGR-5KE.

• 10,000W - 20,000W Systems: Designed for full-family homes running standard appliances, including HVAC systems and laundry machines.

Essential Components

A true turnkey solution includes three pillars of power:

1. High-Wattage Arrays: These kits typically include banks of 12 to 32 panels, often rated at 415W or 450W each, ensuring maximum capture during daylight hours.

2. LiFePO4 Lithium Batteries: Forget old lead-acid technology. Modern kits utilize Lithium Iron Phosphate batteries (ranging from 5.12kWh to 30.72kWh). These offer deeper discharge cycles, longer lifespans, and better safety profiles.

3. 48VDC Inverters: To convert that stored DC energy into the AC electricity your wall outlets need, these kits come with powerful split-phase inverters capable of handling high surge loads.

Portable and Folding Panels

Not every solar project involves a permanent roof mount. For campers, overlanders, and outdoor enthusiasts, mobility is key. The latest generation of portable panels prioritizes lightweight design without sacrificing efficiency.

Briefcase Style Panels

When space is at a premium, briefcase panels are a game-changer. Models like the Nature Power Monocrystalline Briefcase Solar Panels (available in 80W configurations) are designed to be set up in seconds. They fold neatly for protection during transport and include integrated kickstands to angle perfectly toward the sun, regardless of where you park.

Next-Gen Bifacial Technology

Solar technology is constantly evolving, unlike traditional panels that only capture light on the front, bifacial panels have a transparent back sheet. This allows them to absorb ambient and reflected light from the back side, significantly increasing the total energy harvest up to 25% more in some conditions, without increasing the panel's physical footprint.

Solar Panel Packs

One of the most common mistakes in solar planning is underestimating future power needs. You might start with a basic setup, but as you add more appliances or batteries, you will need to increase your input.

Buying single panels can be costly and inefficient for shipping. We offer multi-panel packs to expand your array cost-effectively.  This bulk approach allows for rapid scaling. If you have the land for a ground-mount system or a large barn roof, purchasing a 10-pack of high-wattage panels is the fastest way to build a significant generation station. These rigid, high-efficiency panels utilize PERC (Passivated Emitter and Rear Cell) technology, which improves light capture near the rear surface of the cell, optimizing performance even during low-light conditions.

Specialized Solutions for Unique Environments

Standard rigid panels are durable and efficient, but they aren't suitable for every surface. The curved roof of an Airstream trailer or the sleek deck of a boat presents installation challenges that traditional racking systems cannot solve.

Semi-Flexible Panels

This is where semi-flexible panels excel. We carry lightweight, weather-resistant options. These panels can contour to curved surfaces up to a certain degree, allowing for adhesive mounting. This eliminates the need for drilling holes in your roof and reduces wind drag, making it the preferred choice for marine and aerodynamic vehicle applications.

RV-Specific Systems

Life on the road requires specific voltage management. RV solar systems from are optimized for the limited roof space of recreational vehicles. These systems are designed to keep house batteries topped off while "boondocking" (camping without hookups), ensuring your lights, water pump, and ventilation fans run smoothly without the noise and exhaust of a gas generator.

Solar Power Kits & Charging Kits

It is important to distinguish between a full solar kit and a charging kit.

• Solar Power Kits: These generally include the batteries and inverters required to store and use power.

• Charging Kits: If you already have a battery bank or a solar generator (like an EcoFlow Delta), you don't need redundant hardware. Our charging kits focus solely on the generation side, providing the panels, cables, and charge controllers needed to harvest energy and funnel it into your existing storage.

Frequently Asked Questions

What types of solar panels do you offer?

We offer a comprehensive range including Monocrystalline silicon (known for high efficiency), Polycrystalline, Thin-film, Bifacial (double-sided), rigid, semi-flexible, and portable briefcase styles.

What is the difference between your solar kits and individual solar panels?

Individual panels are standalone units used to expand an existing system. Solar kits are complete packages that often include the panels alongside compatible inverters, batteries, and mounting hardware, removing the guesswork from system design.

Are your solar panels suitable for off-grid applications?

Yes. Our inventory is specifically curated for off-grid use, featuring high voltage capacities and durable materials capable of functioning independently of the utility grid.

What brands of solar panels and accessories are available?

We carry trusted industry leaders including Sungold Power, EcoFlow, Nature Power, Nature's Generator, Pecron, and ACOPOWER.

How do I choose the right solar panel or kit for my needs?

Perform a load analysis to determine your daily watt-hour consumption. Match this against the output of the panel or the storage capacity of the kit's battery.

What power capacities are available for your solar panels?

Our selection ranges from compact 35W flexible panels for trickle charging to commercial-grade 550W panels and 20kW complete systems.

Which technologies are used in your solar panels?
