Solar panels
20W, 40W, 75W, 100W, 165W, 250W, 330W, 450W and 550W class panels for small to larger DC systems.
Direct solar power
Solar DC systems made for lights, fans and mobile charging
We design inverterless DC systems from your actual load: bulbs, fans, battery operated flood lights, CCTV and charging. The box can include lithium battery with BMS, solar charge controller protection and 5V 3A mobile charging.
20W to 550W solar panel range 5A to 60A charge controllers 6Ah to 24Ah+ lithium battery packs PWM or MPPT based on voltage matching
What goes inside
Parts selected for your real DC load
This is not shown as price list. It is to help customers understand which material is used and why.
PWM / MPPT controllers
PWM is economical for same-voltage panel and battery systems. MPPT is better when panel voltage is higher or charging efficiency matters.
Lithium batteries
12V lithium battery packs such as 6Ah, 12Ah, 18Ah and 24Ah with compact size and faster charging.
Battery operated DC loads
DC bulbs, mobile charging, table fan, pedestal fan, ceiling fan, CCTV and battery operated flood lights.

PWM or MPPT
Charge controller selection matters
PWM is simple and economical, but the solar panel voltage and battery voltage should match. If the solar panel is 12V, battery should be 12V; for 24V panel, battery should be 24V. MPPT gives more flexibility and better charging. For example, a 24V panel can charge a 12V battery through a suitable MPPT controller.
Protection role: controller helps prevent battery overcharge, deep discharge and wrong charging behavior when selected and wired properly.
5A20W to 60W
Best for single light, phone charging, small demo kits.
10A60W to 120W
Best for 2 to 4 bulbs or small table fan setup.
20A150W to 250W
Best for home light and fan DC box.
30A250W to 400W
Best for larger room, shop, CCTV and charging loads.
60A400W to 550W+
Best for expandable DC system with multiple loads.
System formats
Compact box or expandable DC setup
Choose according to appliance wattage, operating time, portability and whether you may add more loads later.
Flexible Solar DC Box
Battery with inbuilt BMS, charge controller protection and 5V 3A mobile charging in one practical box.
Best for: Custom lights, fans and phone charging
Rocklight Mini DC System
Compact portable lighting kit with inbuilt battery and DC bulbs for rooms, stalls and emergency lighting.

DC system calculator
Size panel and battery from real usage
Enter loads used between 10 AM and 4 PM as daytime usage. Enter evening/night hours separately. Panel is calculated for both direct daytime load and battery charging, with 20% extra margin.
9W each, row load 18W
18W each, row load 18W
15W each, row load 15W
How we finalize it
We confirm details before material selection
01
List loads
Bulb, fan, mobile charger, flood light, CCTV and quantity.
02
Separate day and night use
10 AM to 4 PM load is direct solar side; after 4 PM is battery backup side.
03
Panel for both jobs
Panel size covers daytime use plus battery charging energy.
04
Keep reserve
We add margin so backup is not cut-to-cut in real use.
