What is the 12v Solar Panel Price? 12V Solar Panels work by converting sunlight into an electric current which can be used to charge batteries or converted using an inverter to safely power 240V appliances such as laptops and phone chargers. While solar panels are simple to set up and use, choosing the right one takes a little more consideration. With a range of solar panel brands on the market, you need to know that the products you are buying will meet your power requirements and are of high enough quality to last.

Our guide to choosing a 12V portable solar panel takes you through what you need to look for in the construction of your panel, as well as sizing information and how to use a solar regulator.

The Difference Between Fixed vs Portable Solar Panels

12V Solar Panels can be used in two main variations, depending on your power needs and the type of trip you’re taking. Fixed Solar Panels are mounted on the roof of your caravan, boat or 4WD to absorb sunlight while travelling or when your vehicle is parked in a sunny spot. Most caravans have a roof space big enough to hold a system that covers the majority of their power needs and there won’t be any set up to worry about when you arrive at your destination. The disadvantage of fixed solar panels is in their positioning – because they will be laid flat atop your vehicle and you may not always park in direct sunlight, they lose around 20% of the power they could potentially produce in a day. With portable solar panels, this is less of a problem. The panels can be placed in the sun and moved to follow its arc while a cable runs back to your battery. This allows you to ‘chase the sun’ and generate the maximum amount of power from your panels. However you will need to allow extra time for setting up and packing down your solar panels as you journey around.

The Cell Quality in 12V Portable Solar Panels is Important

The type of cells used in your 12v portable solar panel is an important consideration. Solar panels are graded on the quality of the photovoltaic cells used in their construction; with the more efficient cells producing the most energy. The three main types of solar cell used in modern solar panels are the mono-crystalline which works best in direct sunlight, poly-crystalline which functions more efficiently in low-light conditions and the less common amorphous cells made from thin, flexible film panels.

Look for a trusted manufacturer behind your solar cells, such as Kyocera. The Japanese brand’s solar cells use multicrystalline technology (a combination of mono-crystalline and poly-crystalline), which features a greater surface area to collect sunlight and increase output.Some lower quality brands will rate their solar cells to a higher wattage than the level they perform at, leaving you with an inferior panel that won’t support your power needs. When it comes to Solar Panels the cheapest options are often an inferior panel and it is worth investing a little more to know that you’re getting a good quality panel that will last and is covered by a warranty. Good quality panels will generally have great standard warranties because the product technology is advanced and has a proven track record.

Best Overall: Renogy 400W Solar Starter Kit with 40A MPPT Charge Controller

  • Watts: 400
  • Volts: 12
  • The High Points: Comes equipped with a Rover MPPT charge controller.
  • The Not-So Good: No battery bank included.

As one of the leading solar energy brands on the market, Renogy offers superior equipment at a competitive price. From efficient panels to reliable charge controllers, the popular brand always impresses. The trend continues with their 400W Starter Kit that comes equipped with a name-brand 40A Rover MPPT charge controller and four 100W solar panels.

The kit includes all the essentials, minus the battery bank, which is easy enough to purchase separately. And if you’d like to expand your energy potential in the future, you can purchase additional Renogy panels to connect to the system. The MPPT charge controller can handle up to 800W (24V) of power.

What Do Reviewers Say?

The majority of reviewers claim that the system is easy to install independently. However, they warn that the kit doesn’t come with installation instructions, so it’s important to do research beforehand. If you have any questions, Renogy’s support team is available to provide advice.

Several buyers have used their kits to power vans or trailers with great success. The 400W rating is ideal for small consumption use while still providing location independence. The lightweight design and easy installation is also a key selling point for travelers looking to power their rigs.

There have been a few complaints to Amazon because the MPPT charge controller was not included in the package. Some question whether or not there are quality checks conducted in the warehouse before the units are shipped. However, this issue was quickly resolved for the reviewer after sending in a support ticket.

Features & Considerations

Renogy’s solar panels use monocrystalline solar cells, which have the highest efficiency rating. This type of solar cell is also lighter, making it easier to install. The entire kit, including bolts, panels and a charge controller weighs in at a reasonable 90 pounds. Each panel is 39.7 inches by 26.7 inches by 1.4 inches.

The kit will need to be supplemented with a solar battery bank. A 300AH gel battery is enough to meet most homeowners’ needs. Alternatively, you can also use golf cart batteries, boat batteries or any other type of power bank to charge your devices.

The Rover MPPT charge controller is another quality addition. The Rover model is a top-tier piece of equipment in its own right. Overall, MPPT controllers are more efficient than PWM controllers, which is why we chose the Renogy MPPT kit over the cheaper PWM kit as our best overall.

The kit also includes mounting Z brackets, a 20ft 10AWG MC4 adapter kit, and 8ft 10AWG tray cables. The kit can be installed on any off-grid system, including RVs, trailers, boats and cabins.

For more specialized kits, like waterproof marine systems, Renogy offers a variety of other options at various price points. However, their 400W starter kit is the best overall option for general use.Click to See Price

grape solar 540w off grid solar panel kit

Runner Up: Grape Solar 540W Off-Grid Solar Panel Kit

  • Watts: 540
  • Volts: 12
  • The High Points: The kit is great for powering small, location-independent consumption systems.
  • The Not-So Good: An expensive price point for relatively low wattage and no included battery bank.

Grape Solar’s unique 540W Off-Grid kit boasts minimal maintenance, easy installation and durability. With a price point that’s more expensive than most other similarly equipped kits, Grape Solar has a lot to prove. However, the well-reviewed system lives up to its marketing; buyers love their kits, no matter the price point.

Overall, the kit is best for off-grid systems like boats, RVs, cabins, sheds, vehicles and tiny houses. It’s not suitable for entire households as it only provides enough power to fuel small appliances and electronic devices. With USB ports and outlets, the system is easy to connect to.

Like the Renogy starter kit, Grape Solar’s kit doesn’t come with a 12V battery bank. This will need to be purchased separately. Otherwise, all essential hardware, including a charge controller, is included. This makes assembly a breeze as you don’t need to scramble to find the right parts for installation.

What Do Reviewers Say?

Reviewers love how easy the kit is to assemble. It comes with an instruction manual that explains the wiring and connectors. However, you will need to build your own frame/panel rack for mounting, which may be a nuisance for novice DIYers.

Even at the relatively high price point, buyers claim that the kit is a great value. With its high-quality materials and excellent customer service, Grape Solar’s solar panel kit exceeds expectations. This should be reassuring for anyone who is worried about investing in a more expensive kit.

Features & Considerations

The 540W rating is a good choice for those looking to fully power small appliances, like pumps, solar lights or laptops. It’s an “in-between” option as most kits offer 100-400W of power, or 1,000W+. Overall, the system can produce roughly 1,620W hours or 135A hours of charge per day.

The kit includes three 180W monocrystalline solar panels, which are the most efficient solar cells available. The panels are also built with an aluminum frame and sealed junction box, so the system is virtually weatherproof. Durability is an important consideration for solar panels, and Grape Solar hits the mark.

Along with the panels, the kit also includes a 40A Comet PWM charge controller. The PWM charge controller is not as efficient as an MPPT controller but it does the job. It also offers mobile monitoring which is great for those on the road.

While the kit does not come equipped with a 12V deep cycle battery which is necessary for operation, it does have a 15A inline-MC4 comparable fuse, a 1,800W pure sine inverter with two outlets and a USB port. The USB port is particularly useful for plugging in small devices.Click to See Price

renogy 3600 watt solar cabin kit

Best for Off-Grid Homes: Renogy 3600-Watt Solar Cabin Kit

  • Watts: 3600
  • Volts: 48
  • The High Points: Can fully power small-sized households or work as a backup source for regular homes.
  • The Not-So Good: Not ideal for those looking to dabble in solar panels.

Renogy, the top-tier brand that topped our list with their 400W starter kit, also offers a variety of other systems. The 3600W Solar Cabin Kit is a powerful addition to any small household. With advanced panels and a host of high-quality equipment options, the kit is ideal for remote cabins, off-grid residences and commercial rooftop systems.

Although the price tag may seem startlingly high for newbies in the DIY solar market, it’s actually a reasonable cost when considering the size of the bundle. The kit comes with a MidNite Classic MPPT charge controller and a MidNite Solar MNPV6 Combiner box. However, you will need to purchase a 48V battery bank separately.

What Do Reviewers Say?

Overall, reviewers are pleased with their purchase. Few buyers have left comments, but those who have are satisfied and have not had issues with installation or output. One reviewer claims they haven’t yet experienced any problems after a year of continuous use.

However, a buyer claimed that no instructions were included in the kit. This may be an issue for those who are not familiar with solar power systems. If this is the case, it’s best to reach out to Renogy’s customer support for assistance.

Features & Considerations

The kit comes with twelve 300W monocrystalline solar panels. The panels use PERC solar cells, which are more efficient. Overall, each solar panel is 15-20% shorter and lighter than a regular 72 cell 300W panel.

The solar panels are able to withstand high winds (2400Pa) and snow loads (5400Pa) should you live in a climate with frequent inclement weather. This durability makes it ideal for rooftop mounting on residential or commercial buildings. The panels also boast the ability to perform well in low-light environments.

In each kit, you’ll find a MidNite Classic 150 MPPT charge controller. This industry favorite is a leader in remote monitoring and offers a wide range of features and more control over the system compared to PWM charge controllers. There’s also a MidNite Solar MNPV6 Combiner Box, another popular piece of equipment, which is rated for outdoor use.

Renogy guarantees a positive output tolerance (0-3%). They also offer a 25-year power output warranty on the panels, a 5-year material warranty and a 1-year accessories warranty. This may ease potential buyers’ concerns about the upfront investment in an entire system that’s not backed by a professional installation and solar service company.Click to See Price

allpowers 100w solar panel charger

For Those on a Budget: ALLPOWERS 100W Solar Panel Charger

  • Watts: 100
  • Volts: 18
  • The High Points: A unique, flexible design offered at a low price point.
  • The Not-So Good: Doesn’t offer the ability for expansion as you’re limited to a low number of panel connections.

The 100W solar panel kit by ALLPOWERS is a great option for new solar DIYers or those looking to power small devices. Although the kit is cheap, it still offers some great perks, like a flexible panel, 18V output and super simple mounting design. Not only that, but ALLPOWERS boasts a 21% panel efficiency rating, compared to the standard 15% of other panels.

Although there are certainly cheaper 100W panels on the market, the ALLPOWERS model rises to the top because of its quality and features. However, be aware that you will still need to purchase a battery bank and charge controller separately which will significantly increase your overhead costs.

What Do Reviewers Say?

Purchasers are pleased with the overall quality and capacity of the ALLPOWERS solar panels. Various verified uses include camping vans, boat refrigerators, charging iPhones, water pumps and tiny houses. The wide range of applications make this a great option for most buyers.

However, one reviewer claimed that they faced issues when connecting two panels in a series. The voltage dropped and the reviewer did not know if this was a result of faulty panels or their charge controller. Whatever the cause, this may be a red flag for those looking to expand their system for higher capacity output.

Features & Considerations

ALLPOWERS solar panels offer a relatively innovative feature: flexibility. The SunPower panel is semi-flexible and the plastic back sheet can be bent into a 30-degree arc. This flexibility means that it can be mounted on a variety of irregular surfaces, like cars, trailers or boats.

The 100W solar panel is made with monocrystalline solar cells, which have a high conversion efficiency rating. Each panel only weighs 4.1 pounds, making it easy to transport and install. The unique frameless design with pre-drilled panel holes is also an added benefit for those on the go.

ALLPOWERS recommends that you should not use more than 2 panels in parallel with a PWM controller, or 4 panels in a series connection with an MPPT controller. This means that the total wattage available is fairly low, and you are limited by the number of panels you can install. You will also need to purchase an 18V battery bank and solar charge controller.Click to See Price

You will not need to do any setup, including tools or wiring. Simply stop your RV, pop out the standing legs and start charging.

What Do Reviewers Say?

The quality of construction and efficiency of the ACOPOWER portable kit thoroughly impresses reviewers. Successful applications include being used as RV solar panels, and for disaster relief and camping. People have even used this all-purpose kit in stationary capacities, like a household.

One reviewer claims that it outperforms other similar models made by other brands. The peak efficiency rating was consistently higher. This should provide confidence for those comparing other brands and/or models to ACOPOWER’s 105W suitcase kit.

However, some have had issues with the panels being too delicate. The crimp-on wire ends that secure the controller have a gap which exposes the wires. This can become an issue in the future if it isn’t fixed.

Features & Considerations

Perhaps the greatest selling point for ACOPOWER’s solar panel kit is its unique “suitcase” design. The panel is actually three separate 35W panels mounted on a foldable surface. This tri-fold option is great for those looking to regularly transport their panels, like those traveling in an RV or on a boat.

The entire compact kit is only 7.9 pounds and can be reduced down to a size of 22 inches by 17 inches by 50 inches. The laminated panels and mounting surface are also weather-resistant and can be safely used in rain. The panels come equipped with a back prop stand for easy and quick assembly on the go.

The kit comes with an SAE connector for pre-wired Zap Solar RV or campers. You can also purchase additional adapters from the company. On top of that, you will need to acquire a 12V battery that’s compatible with your devices.Click to See Price

Overall, WindyNation’s all-inclusive kit is great for powering small devices and appliances in cabins, RVs, or small households.

What Do Reviewers Say?

Reviewers appreciate the comprehensive scope of the kit. It really does include almost everything you need to begin. Some have chosen to purchase additional hardware or accessories to customize their kit. However, this is not necessary for installation.

One reviewer claims that the solar inverter is not good quality. They also found the wires that come with it to be too short for general use. These may add a few extra hundred dollars to the overall price if you need to replace or repair the defective items.

Features & Considerations

As one of the most comprehensive kits on the market, the WindyNations 400W kit packs a punch. It includes four 100W panels, a 30A solar charge controller, a 1500W VertaMax power inverter, four 100Ah BattaMax deep cycle batteries, a variety of cables and mounting hardware.

The equipment is fairly basic and doesn’t offer the most advanced technology. The panels are polycrystalline, which isn’t the most efficient, and the charge controller is a PWM rather than MPPT model. However, the comprehensive scope of the kit is great for those looking to eliminate the stress of finding the right components for your system.

The included 1500W inverter works to convert DC to AC power, which is ideal for running household appliances. You can also use it to power RVs, cabins, boats and backup systems. On average, the panels provide 1600W hours of charge per day, depending on available sunlight.Click to See Price
