Nowadays, solar system is used a power source to support embedded system application in remote area. This research aimed is to design and develop a Stable Solar Power Management System (SSPMS) for TS-7800 Single Board Computer (SBC) and called Solar Power Supply And Management For Remote Embedded Linux System (SPsmRELS). The main board is TS-7800 SBC, and the other peripherals are TS-9700 ADC, 3G USB modem, solar panel, battery, voltage regulator and sensors. TS-7800 SBC is controlling part for the whole system. The solar panel connected to the battery through the voltage regulator circuit to provide the battery with required voltage. The TS-7800 connected with the battery through a voltage regulator circuit which manages to serve 5V to TS-7800 SBC where the battery output voltage up to 12V (full charge). A notification is sent to the user once the battery is low. The SPsmRELS development base is C language. Debian/Linux 6.0.0 (Squeeze) operating system is used to support 3G USB Modem which is used to communicate between SPsmRELS and admin through SMS. The battery and solar panel data are stored into a database into TS-7800 SBC to let the admin able to monitor the data by web-browser. The experimental results show that the SPsmRELS able to support maximum seven (7) hours at full change. An interesting feature for SPsmRELS is, admin may get access to the database through any web-browser and can shutdown the SPsmRELS by sending SMS contains (init 0).
