About Amorphous Solar Power
Solar panels convert sunlight into an electric current, they do not store power. Amorphous solar panels are created by spraying silicon onto glass in very thin layers, and are commonly known as thin film solar panels. This process allows them to be better at generating electricity in all lighting conditions, including cloudy or shady environments. They have a maximum operating temperature range of -40 to 176-degrees Fahrenheit, requiring virtually no maintenance. They can even withstand impacts from one-inch hailstones at 50 miles-per-hour.

Advantages of Solar Power
We’ve pretty well established that Going Green News is all for environmentally safe, sustainable and renewable resources. In other writings, we’ve defined that as (primarily) solar, wind and water generated. Hydrogen technologies are not yet commercially viable, so we don’t include them at this time. In this article we’ll be looking at the advantages that Solar power offers over other Green technologies.

  • Low/no maintenance. Once a solar farm is set up, the panels go on collecting energy for a long time with minimal care.
  • Low space requirements means that they can be mounted most anywhere, including rooftops (which are often wasted space.)
  • Solar isn’t just photo-electric. It can also be used to heat homes, heat water for cleaning and bathing, etc.
  • Small solar chargers can deliver portable energy to gadgets and light-duty devices, freeing us from plug-ins.
  • As we become more energy conscientious, more devices will be engineered to operate on minimal energy (and solar cells will become more effective at harnessing the sun,) making solar devices as common as the solar calculators we’ve been using for decades.

These five points go far to demonstrate how solar power is feasible and useful now. People have been using solar energy as their primary source for a long time, and the advancements in solar technology just keep on coming. When we consider the nearly incalculable power of the sun’s rays, it’s clear that solar technologies must be a major part of our Green energy solutions.

7 reviews for 5.5 W Solar Battery Trickle Charger 12V

  1. 4 out of 5


    Was easy to install, seems to be made well, it even impressed the electrician installing my generator transfer switch, who said he was going to get one for his boat. The only thing nicer would be a led light to tell if it is operating ok.

  2. 4 out of 5


    bought for my dad to use on his horsetrailer to keep the battery charged up so he would not have to run a cord to it. easy to hook up and can mount solid or take with you.

  3. 5 out of 5


    This solar panel is fun to play with, but you will soon find it doesn’t supply enough power to be very useful.

    It’s probably adequate to charge small batteries or run small motors or electronics, but not enough to keep a car sized 12v battery charged.

    I think its intended to be left in a stationary vehicle that starts out with a charged battery, and it simply compensate for the natural battery voltage loss over time.

    If you are thinking of using a battery every day and charging it back to full power with the solar panel, you’ll need to get a bigger one.

    This unit is very efficient, and has voltage production even in dim light. In direct sunlight, it’s around 18-19 volts.

    No complaints right now, keeping my to Rv batteries charged as far as I can tell ok product, helps with electric bill.

  6. 5 out of 5


    I bought this to charge the battery on my sailboat. Delivered on time and just as described. Plugged in right out of box, no setup just clamped onto battery terminals and works great. Keeps battery topped off.
