DIY off-grid solar kits can be purchased from major e-commerce platforms like Tmall and JD.com, which offer components ranging from small-scale LED light panels to full residential systems. For industrial-grade solutions, specialized manufacturers like Zhuhai Tianzhao New Energy provide customized photovoltaic pumping and irrigation systems. Key considerations include voltage compatibility (e.g., 5V monitoring systems vs. 220V home kits) and battery capacity requirements.

What basic components are available on Tmall?
Tmall hosts entry-level DIY solar components like 3.2-3.7V LED light panels (¥16.9) and 5V solar security camera kits (¥33.1). These kits feature pre-soldered connectors and basic charge controllers, ideal for small-scale projects like garden lighting. Pro Tip: Combine multiple 5V panels in parallel to power 12V systems while maintaining stable amperage.
For example, the 3.7V circular solar panel (No.7 on Tmall’s sales chart) uses monocrystalline cells with 18% efficiency—sufficient for 6-hour LED operation after full sunlight exposure. However, these budget components lack weatherproofing, requiring additional silicone sealing for outdoor use. Transitional note: While Tmall excels in affordability, larger systems demand more robust solutions.
Where to find complete home solar kits?
JD.com sells full 220V off-grid systems like Jingbiao’s hybrid inverter kit (¥28,453) containing 5kW inverters, lithium batteries, and 20x450W panels. These include MPPT controllers and automatic grid-switching capabilities for uninterrupted power. Warning: Always verify your regional electrical codes before installing high-voltage systems.
| Feature | Basic Kit | Premium Kit |
|---|---|---|
| Inverter Type | Modified Sine | Pure Sine |
| Battery Type | Lead-Acid | LiFePO4 |
| Panel Efficiency | 16% | 22% |
Transitional note: Beyond residential systems, agricultural solutions require specialized configurations. The Zhuhai Tianzhao 26KW solar pumping system demonstrates how commercial-grade kits integrate submersible pumps with maximum power point tracking for irrigation projects.

FAQs
Technically yes, but impractical—connecting 100+ 5V panels to achieve 5kW would create complex wiring vulnerabilities. Start with purpose-built 24V or 48V systems instead.
Do JD.com kits include installation?
Most require self-installation, though some sellers offer paid technician dispatch. Always confirm local service coverage before purchasing premium systems.
