Description of πŸ”† Joytech 1PC 1.5w 5.5v 270ma Mini Solar Panel Module - DIY Polysilicon Solar Epoxy Cell Charger - Efficient Solar Energy for Small-scale Projects - B008

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. DIY YOUR OWN SMART MODEL---- Build your own powered models, solar toys, solar lights, solar displays, charging small DC batteries. It can be used for teaching purpose. Many of our customers come from school, colleague, etc. 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.

High Output Power

The product is designed for 0.27 A and 5.5 V or 1.5 W. Actual performance in FL in full sun is only 1/2 that. Actual output current into a 40 ohm load is 0.1375A (138mA) while maintaining 5.5V or just 0.76W. Disappointed!

Pros
  • HIGH QUALITY ---- High quality epoxy resin, unique technology to make the components beautiful and strong, windproof and snowproof, and extend the life of solar panels.
Cons
  • Small parts

I give 5 stars for a good job guys

The item was well packaged. It puts out 6V in the bright sun, and the coating isn't cheap plastic that instantly fogs up on its tempered glass. I will order more soon. I give 5 stars, well done guys.

Pros
  • EDUCATION ---- Solar panels are devices that absorb sunlight and convert solar radiation directly or indirectly into electricity through photovoltaic or photochemical effects, ideal devices for science projects.
Cons
  • No

Excellent design, suitable for solar and wind power.

These small modules have a nice glass finish that will likely last a lot longer than other manufacturers' epoxy embedded modules. The picture shows 11 cells in series, that's 5.5V. My modules only came with 10 cells in series, so only 5V. This may not be a problem for most applications, but if you plan on using 3 in series to charge the lead 12V acid batteries, it probably won't work with 10 cell batteries. Update: I placed another order, free blocking diodes came as a gift. It would be nice if

Pros
  • PARALLEL OR SERIES CONNECTION OF SOLAR PANELS ---- If your solar panel voltage is not satisfying your battery, you can connect two or more identical solar panels in series. For example, two 5.5V solar panels are connected in series, so their voltage is 11V when the solar panel voltage is the same as your battery pack. To speed up the charging process, you can connect two or more identical solar panels in parallel.
Cons
  • Durability
