RV Solar System Costs in 2024: Your Complete Pricing Guide

Sep 9, 2024, 6 mins read

Introduction

Dreaming of breaking free from noisy generators and campground hookups? Solar power is the perfect solution for RVers looking to embrace the open road with independence and eco-friendly energy. Whether you're a weekend warrior or a full-time nomad, by the end on this article you'll know how much your dream solar system can cost.

Understanding RV Solar Basics

An RV solar system consists of four key components: solar panels, batteries, a charge controller, and an inverter. Each plays a vital role in converting and storing energy from the sun, with system complexity varying based on your energy needs.

  • Solar Panels: These can be rigid (roof-mounted) or flexible (adhered to curved surfaces). Monocrystalline panels are more efficient but pricier, while polycrystalline panels offer a more budget-friendly option.

  • Batteries: Lead-acid batteries like AGM are affordable but have a shorter lifespan compared to lithium-ion batteries, which can last up to 10 years but cost more.

  • Charge Controller (MPPT): Regulates electricity from panels to batteries, ensuring efficient charging and preventing overcharging.

  • Inverter: Converts DC electricity to AC for your appliances. It's best to use a pure sine wave inverter to protect sensitive electronics.

Breaking Down RV Solar Costs

Everyone's energy needs are different. Depending on how much solar power do you need for your RV, the budget will vary too. Here’s a more detailed guide to help you understand the potential costs for different sizes of RV solar setups and what components you might need.

1. Minimal Off-Grid Solar System

If you're a weekend camper who only needs to power small electronics such as lights, fans, laptops, mobile hotspots, TVs, and cell phone boosters. This setup is sufficient if you're spending short weekends off-grid, but it won't provide enough power for your refrigerator or the AC with solar energy.

Components:

  • Battery Bank: 200 Ah of Lead-Acid or 125Ah of Lithium batteries
  • Solar Panels: 200–400 watts of solar panels
  • Charge Controller: 30 Amp MPPT Solar Charge Controller
  • Inverter: 1500–2000-watt pure sine wave inverter

Cost of all the components: $1,500 to $3,000

2. Typical Boondocking Off-Grid Solar System

If you’re a part-time traveler or boondocker, and you need more power or want to power your refrigerator with solar, this mid-level setup is got you covered. This system gives you the flexibility to camp off-grid for extended periods and power everything except the AC. It's a great choice if you enjoy the comfort of a few luxuries while boondocking.

Components:

  • Battery Bank: 600Ah of Lead-Acid or 400Ah Lithium batteries
  • Solar Panels: 600–1000 watts of solar panels
  • Charge Controller: 30–60 Amp MPPT Solar Charge Controller
  • Inverter: 2,000–3,000-watt pure sine wave inverter

Cost of all the components: $4,000 to $8,000

3. Large Power Load Off-Grid Solar System

For full-time RVers who want the comfort of a home on wheels, especially the ability to run energy-intensive appliances like air conditioning without generator noise, a large solar system is essential. This setup allows you to go completely off-grid without sacrificing convenience, making it ideal for long-term RV living.

Components:

  • Battery Bank: 800+ Ah of lithium batteries (for maximum energy storage and long-lasting efficiency)
  • Solar Panels: 1500+ watts of solar panels (enough to handle heavy electrical loads)
  • Charge Controller: 60 Amp MPPT Solar Charge Controller (for optimal charging efficiency)
  • Inverter: 3,000-5,000-watt hybrid inverter (to seamlessly manage solar and generator power)

Cost of all components: $8,000 to $18,000

Factors Influencing Your RV Solar Budget

Several factors can influence the final price of your RV solar setup. One of the biggest is your RV’s size and energy consumption. Larger rigs require more power, which means more panels and bigger batteries.

  • Energy independence: If you plan to go completely off-grid, you’ll need a more robust setup (and a bigger budget) compared to someone who just wants to supplement shore power.

  • Quality of components: While it’s tempting to go for cheaper options, trust me, you don't want to get stranded in the middle of nowhere because a component failed, and you have no power. Investing in high-quality components, such as lithium-ion batteries and monocrystalline solar panels, can save you money in the long run by reducing maintenance and increasing system longevity.

  • Location and weather are also key. If you’re camping in areas with less sun exposure, you may need more or higher efficiency panels to meet your power needs.

RV Solar Installation Costs: DIY vs. Professional

You can either install an RV solar system yourself or hire a professional, depending on your budget and comfort level with electrical work.

DIY Installation

A DIY installation saves on labor but requires tools like wire crimpers, cable strippers, multimeter, wrenches, and mounting hardware. You may also need soldering iron. DIY installation demands time and effort to ensure proper setup and troubleshooting.

Things to watch out for:

  • Electrical safety: To build the system yourself you'll need solid electrical knowledge. Making a mistake can have serious consequences ranging from damaging equipment to death.
  • Time commitment: DIY installs can take longer, especially if you're learning as you go. Plan for extra time and potential delays.
  • Warranty implications: Some manufacturers may void the warranty if the system isn't installed by a certified professional.

Professional Installation

A professional installation typically costs $75 to $150 per hour, with labor taking from a few hours to a couple of days depending on the size of the system. Hiring a professional guarantees the job is done safely and efficiently.

Things to watch out for:

  • Labor costs: Be clear on the expected time and total labor costs before committing to a professional.
  • Licensed Installers: Check if the installer is licensed and certified, as this can impact the validity of their guarantee and the product warranties.
  • Warranty: Availability can sometimes be limited, and installation might take time to schedule, especially in peak seasons.

Calculating Long-Term Savings and ROI

Now that we’ve covered the upfront costs, what about the long-term savings? While RV solar systems require an initial investment, they can pay off in multiple ways.

  • Energy savings add up over time, especially if you frequently camp off-grid. By avoiding campground hookup fees (which can average $50–80 per night), you can recoup your investment and turn to profit fast.

  • Resale value of a solar-equipped RV. Many buyers are willing to pay a premium for rigs with off-grid capabilities, meaning you could recoup even more of your investment when it’s time to upgrade.

Conclusion

Going solar can unlock a whole new level of off-grid freedom for your RV. Now that you understand the costs, it's time to take the next step! Explore my solar kit top picks to find the perfect setup for your adventures.
