Frequently Asked Questions

Check out our great FAQs and Answers for our Marine Solar Panels below:

Do I need to buy a charge controller for an Automotive or Marine Solar Panel?

No you do not.  The panel has a trickle charger installed into it. This means that the panel can lose some capacity in storage due to self-discharge, but with a trickle charger it will replaces lost amp-hours to your battery.  This will ensure a  quick start and extending battery life.

What is the difference between our Isol 4x and our TravelSol 2x battery chargers?

Our Isol 4x battery charger has a solar panel that is 0.44 watts.  OurTravelSol 2x battery charger has a solar panel that is 2 watts.  Since the TravelSol 2x has a bigger solar panel it will therefore charge your mobile devices faster than the Isol 4x.

How long will it take my Isol 4x to charge my mobile device?

On a sunny day it will take one to two hours for your Isol 4x to charge your mobile phone.  It has a LED 1, LED 2, LED 3, and LED 4 on the device.  When the LED 1 is blue that means there is 10% to 25% of power available.  When the LED 1 and LED 2 is blue that means there is 26% to50% of power available.  When the LED 1, LED 2, and LED 3 is blue that means there is 51% to 75% of power available.  When all 4 LEDs are blue that means there is 76% to 100% power available.

How long will it take my TravelSol 2x to charge my mobile device?

For every hour you charge your mobile device with the TravelSol 2xit will give you 1 to 2 hours of talk time.  The TravelSol 2x comes with 4LED settings, which will show you how much sunlight your panel is receiving.  LED 1 means the product is not charging well.  LED 2 to LED 3 means the product is charging good.  LED 4 means the product is charging super fast.  Most IPhones or Smart Phones will charge between a LED 2 and a LED 4 depending on the weather conditions that day.

Will the TravelSol 2x and Isol 4x charge my Nook?

Yes, the TravelSol 2x and Isol 2x can charge your Nook.  They can also charge cell phones, ipads, kindles, cameras, and other mobile devices.

How many batteries can I charge at a time with the TravelSol Flex Charger?

The TravelSol Flex Charger can charge 2 AA, 2 AAA, 2 C, and 2 D batteries at a time.  You can not charge two different batteries at the same time, such as an A and a C.

Are Solar Trickle Chargers Any Good?

If used correctly, for the right goal, solar trickle chargers work great.  Solar trickle chargers are not designed to fully recharged drained or nearly drained batteries.  A solar trickle charger is designed to maintain the current level of a deep-cycle battery.  In other words, you can have a vehicle sitting for an extended period of time without having the battery go dead from disuse because the solar trickle charger keeps the battery level maintained.

Where can I use the Marine Solar Panel?

We have built this Marine Solar Panel to be used in extreme weather conditions. It can also withstand salt water, so it is perfect for charging your boat. The blocking diode within the weather resistant junction box protects from reverse current during hours of darkness.

How to use the Marine Solar Panel:

The Marine Solar Panel must be connected to a charge controller to ensure that your battery does not overcharge and die. There are steps in your installation kit to direct you on how to properly connect the solar panels to the charge controller to the battery or device being charged.

The Marine Solar Battery Chargers are made with amorphous cells, which are much lower in price than their crystalline counterparts, though they also have a lower module efficiency. These types of solar cells are made from a non-crystalline form of silicon, and thus contain much less of the material which allow them to be significantly thinner than crystalline cells. While some crystalline cells are rigid and can be quite fragile, amorphous cells, also known as “thin-film” cells, and quite durable and can even be flexible. They also perform very well in indirect light and in high heat compared to other types of cells. Amorphous cells are extremely versatile and can therefore be used in a wide range of applications, but you are probably most familiar with their use in small electronics such as calculators.


Solar Panels – Collects solar energy and produces electricity to charge the battery.

Battery – Stores the energy provided by the solar panel.

Built in Blocking Diode – Prevents reverse charging from battery.
