The Sunforce solar charging kit is not a killer deal, but it was one way back when it was released in the year 2005. The Sunforce 50048 charger kit is a delicate gear which is suited for homes and RV(Recreational vehicles), cabins, boats, back-up and remote power use.

In the box
Complete kit includes four 15W amorphous solar panels, a PVC mounting frame, a 7-amp charge controller, 200-watt inverter, and wiring/connection cables.
Amorphous silicon solar panels are prepared as thin films on glass plates by spraying technique. Thin film silicon is better at work than wafers as its heating by the sun light is lesser than in the relatively thick wafers, but higher solar insolation can heat up the panel decreasing its efficiency.
Each panel is rated for the production of 15 watt power and the kit has 4 panels.
Each panel is of dimension, 42.5” x 1.5” x 16.0”. The operating temperature range is -40 to 176 degrees Fahrenheit.
PVC mounting frame is light weight and could be assembled easily. But it could be disoriented by heavy winds and the polymer could also be damaged by sunlight making it brittle.
Sine wave power inverter: Rated at 200 watt, the sine wave inverter could produce steady current.
Built-in blocking diode: The diode prevents the battery discharge at night since the solar panel would be at very low potential (almost zero).
Solar charge controller: 7 A charge regulator regulates the charging of the battery without overcharging.
Wiring kit: Required wires for electrical connections make it easy to install.
The above product does not include the 12V battery intended for storing the electrical power.
This can be used for charging a battery or to maintain the charged state of the battery.
- Light weight support frame.
- Easy assembly and dismantling.
- The charge regulator controls the charge in the battery efficiently.
- The amorphous solar panel has lower efficiency compared to monocrystalline panels.
- The solar panels are heat intolerant.
- Does not produce electricity in low lighting/on cloudy days.
- Cheap plastic construction and the PVC pipe which holds the panel over the RV gets brittle after 3 months of sun exposure.
