Renogy 400 Watt 12 Volt Monocrystalline Solar Starter Kit with Wanderer

Features

  • IP65 Waterproof
  • Multi-electronic protection (Overcharge, overload, short-circuit, and reversed polarity)
  • 4-stage battery charging process for fast and safe battery changing
  • EL tested for no hot spot heating or heat resistance
  • Corrosion resistant aluminum frame for longer outdoor usage
  • Monocrystalline cell panel
  • Temporary powertap back sheet

The Renogy Monocrystalline Solar Starter Kit includes four 100-watt monocrystalline solar panels, two solar Y branches, two 20-ft 10 AWG solar adapters, four mounting Z brackets, a pair 8-ft 10 AWG tray cables, and wanderer lithium 30A PWM charge controller. 

WHAT WE LIKE

The panels have an aluminum frame that prevents corrosion for long periods of outdoor usage. It has been tested with electroluminescence for any hot spotting and to check for heat resistance from UV rays. They are also tested for impermeability against water when in need of cleaning with a water nozzle, and resist environmental damage. With mounting Z brackets have holes that are pre-drilled for easy and secure assembly on the back of the panels.

The battery can hold go on for 2,000-Wh (watt hours) with a 4-stage battery charging process for fast and safe battery charging with 25 years of power-running performance. It also includes a temporary powertap for any power outages or any electrical appliances used outdoors.

The kits best feature is their lithium 30A PWM charge controller aka the Wanderer. The wanderer provides multi-electronic protections for the solar panels from overload, short-circuit, overcharge, and reversed polarity. And wiring can be assembled with ease.

WHAT WE DONT LIKE

The only flaw is that you must carefully follow the manual instructions or you might accidentally break the controller or the wiring.

DOKIO 110w 18v Portable Foldable Solar Panel Kit (21x28inch, 5.9lb) Solar Charger With Controller 2 Usb Output To Charge 12v Batteries/Power Station (AGM, Lifepo4) Rv Camping Trailer Emergency Power

Features

  • Lightweight and ultra thin for travel
  • Foldable and hangable
  • For outdoor usage and emergency usage
  • Has a maximum power point tracker to convert high voltage DC into lower voltage for charging.
  • Monocrystalline cell panel
  • Multi-electronic protection (Overcharge, reverse polarity, short-circuit, and overload)

The Dokio Portable Foldable Solar Panel Kit holds up to its name very well. It’s lightweight and ultra thin monocrystalline panels makes it easy when it’s time to pack up camping gear and easy to carry around in one hand. You can use it anywhere in your vehicle to a remote area with no power source nearby.

WHAT WE LIKE

Instead of a PWM charge controller, the Portable Foldable Kit has an MPPT (Maximum power point tracker) connected to the 12 volt batteries. It’s able to provide multi-electronic protections as well while it converts high voltage direct currents into lower voltage for battery charge. It also includes USB ports to charge your cell-phone.

However, it’s portability comes at a price. When shadows begin to hit the solar panel, the charge will either stop immediately or will cause the power to drop. The kit is designed for emergencies instead of daily use, making it weak to withstand longer weather conditions and should not be left outside at night. While it is waterproof, it is not an attachment for boats.

WHAT WE DONT LIKE

Even though the kit is advertised to be 18-volt, it is only the outputs that are 18 volts while the batteries are actually 12 volts. You’ll need to connect a second panel to double the power.

Newpowa 2 Piece 100W Polycrystalline Photovoltaic PV Solar Panel Module, 12V Battery Charging

Features

  • Lightweight and ultra thin for travel
  • Foldable and hangable
  • For outdoor usage and emergency usage
  • Has a maximum power point tracker to convert high voltage DC into lower voltage for charging.
  • Monocrystalline cell panel
  • Multi-electronic protection (Overcharge, reverse polarity, short-circuit, and overload)

The Newpowa Solar Panel Module is a polycrystalline photovoltaic solar panel made with EVA (ethylene, vinyl, acetone) and coated with a high transparent, low-iron tempered glass. Its rugged design can withstand wind at 2400 Pa (Pascals) and snow at 5400 Pa. The mounting brackets are pre-drilled with holes made for easy installation.

WHAT WE LIKE

The junction box has built-in bypass diodes to minimize the solar power from dropping from shadow particles. It has a very durable temporary powertap that is also heat resistant. The wiring is pre-attached with a 3-feet MC4 wire connection. Like the Renogy solar panels, they can run 25 years of power and are attached to a 12-volt battery.

WHAT WE DONT LIKE

While it’s powerful and affordable, it’s not a kit like the previous two marine solar panels. You will have to buy the mounting racks separately. Luckily, the Newpowa solar panels are adaptable to newer mount bracket models. Currently, the panels are adaptable to these mounts:

  • NPB-UZ
  • NPB-100P
  • NPB-0103
  • NPB-200P
  • NPB-400P

It will also need a PWM controller or an MPPT to protect it from additional electrical problems.

ACOPOWER 35 Watts 35w Polycrystalline Photovoltaic PV Solar Panel Module for 12 Volt Battery Charging

Features

  • Polycrystalline cell panel
  • Multi Off-Grid System (12v/24v/36v/48v)
  • Lightweight Aluminum Frame
  • Reinforced Safety and Anti-Reflection Coated Glass
  • !P65 Waterproof

The Acopower Polycrystalline PV Solar Panel is coated in reinforced safety and anti-reflection glass to prevent heat damage with a lightweight aluminum frame. It’s also easy to attach to your boat and RVs with the pre-drilled mounts.

WHAT WE LIKE

Similar to the Newpowa Solar Panel Module, it is resistant to winds and snow. And it works well as an off-grid power source, working up to 12-volt battery charge to 48-volt battery charge. The Acopower Solar Panel also comes along with its own junction box that is water resistant to allow the panel to last longer periods of time.

WHAT WE DONT LIKE

There are two flaws to point out with the Acopower Solar Panel. The wattage is very weak compared to the previous solar panels and will need to buy multiple panels to your liking. It also needs a controller to prevent additional electrical problems.

WindyNation 200 Watt (2pcs 100 Watt) Solar Panel Complete Off-Grid RV Boat Kit with LCD PWM Charge Controller + Solar Cable + Mounting Brackets

Features

  • Lightweight and ultra thin for travel
  • Foldable and hangable
  • For outdoor usage and emergency usage
  • Has a maximum power point tracker to convert high voltage DC into lower voltage for charging.
  • Monocrystalline cell panel
  • Multi-electronic protection (Overcharge, reverse polarity, short-circuit, and overload)

The WindyNation Solar Panel Complete Off-Grid Kit provides two 100-watt solar panels, two branch connectors, a 30-amp solar charge controller with an LCD display, a pair of solar panel mounting bracket and fastener, and two 40-feet 12 AWG cables and connectors. 

WHAT WE LIKE

What makes WindyNation Solar Panels special is that it’s able to provide power without having to lay power cables. Having two or more back-up panels will activate during a power outage to keep your appliances running such as your fridge to keep your food from spoiling and your laundry equipment running.

WHAT WE DONT LIKE

Its battery does give this one it’s drawbacks. Each panel runs on a 12-volt battery. We mentioned that having two or more back-up panels can be useful during a power outage. Meaning you will have to order an extra kit to make that into a reality.
