Description of πŸ”† Sunnytech 1pc 3.5W 6V 583mA Mini Solar Panel Module: Solar System Charger for DIY Projects (Model B033)

PORTABLE---- Mini solar panel, compact & stylish size, easy to be held, can be easily taken to outdoor activity. SUFFICIENT ENERGY---- High conversion rate, high efficiency output, excellent weak light effect. HIGH QUALITY---- High quality epoxy resin, unique technology to make the components beautiful and strong, anti-wind and snow, increase the service life of solar panels. EDUCATION---- Solar panels are devices that absorb sunlight and convert solar radiation directly or indirectly into electricity through photoelectric or photochemical effects, it's perfect devices for science project. CONNECT SOLAR PANELS IN PARALLEL OR IN SERIES---- When the voltage of your solar panel doesn’t satisfy your storage battery, you can take two or more same solar panels together in series. Such as, two 5.5v solar panel connect together in series, so its voltage is 11V. When the voltage of solar panel satisfies your storage battery. In order to speed up the rate of charge, you can take two or more same solar panel together parallel connection.

Good price, decent size/performance ratio as advertised.

Using this panel in various configurations has always performed reasonably well. It's great for all BQ/CN family 1A charging ICs etc. I have nothing bad to say about it and recommend it to others.

Pros
  • Excellent overall performance
Cons
  • Fair

You have to solder yourself.

No instructions included and no soldered connections on the back. This means it's not really clear which terminals to solder to and you'll have to do it yourself. Other components already have connections (e.g. USB or DC cylinder) soldered onto the back.

Pros
  • Cool product
Cons
  • Unreliable

Works great for charging batteries or 2 for USB power.

Works great for charging batteries or 2 for USB powering devices (6V / +1000mA = 2 panels in parallel) does not contain a diode but has a nice printed circuit to put it on to assemble the positive side. Not sure which is the positive side? Enter positive and negative values in Google Translate to translate Chinese characters.

Pros
  • Great for me
Cons
  • Legacy model

Works but needs help after a year of operation

Works, foil needs to be removed. Then solder some wires to the pads on the back. A good trick I've used is to coat the solder and surrounding contact area with epoxy or ShoeGoo to keep the wires secure. The performance was excellent for about a year, then the surface of the panel became dull and it stopped working. Most likely from the sun and the weather. I used the Scotchbright side of the sponge to clean the matte finish and then applied some car wax. Started working again.

Pros
  • Few competitors
Cons
  • Negative present

Delamination renders this disk unusable.

The product arrived with two small "bubbles" of delamination which in less than an hour in the sun grew into a huge amount of bubbles under the thick glass surface. These bubbles were NOT due to a protective plastic film remaining on it (my husband removed this thin film), they formed between the solar cell and the top glass surface when the panel was heated in the sun (85 degrees). My husband couldn't push the bubbles down or pierce them with a needle because the bubble was under the "glass"…

Pros
  • Pleasing
Cons
  • Useless Features
