What is the best solar panel kit for my camper or motorhome

Power Output
Higher-wattage panels generate more electricity and recharge batteries faster.

Panel Sizes
We offer solar panels from 50W to 660W.
They can be connected in series (higher voltage) or parallel (higher current) for more power.
A solar charge controller regulates the power going to your battery.

Panel Types

• Monocrystalline: More efficient, takes up less space
   
• Polycrystalline: Lower cost, but needs more surface area for the same output
   

Busbars (BB)
These are the fine silver lines on the panel that carry the electricity.
Modern panels use 4 to 12 thinner busbars to reduce shading and heat, improving efficiency.

Half-Cell Technology
Newer panels split each solar cell in half to improve performance in shade and keep the panel cooler.

Summary
More watts = faster charging.
Modern designs = better performance.

 PWM vs MPPT – What’s the Difference?

A solar charge controller sits between your solar panel and leisure battery. Its job is to reduce the panel’s higher voltage (typically 18–55V) down to a safe level for charging a 12V battery (around 13.3–14.6V), depending on the battery type.

A simple, cost-effective controller – ideal for lead-acid batteries like wet, AGM, and GEL.

• Efficiency: 70–80%
   
• How it works: Sends short pulses of energy to match battery voltage
   
• Downside: Doesn’t convert unused voltage – excess power is wasted
   
• Not suitable for lithium: The pulsing can interfere with the battery’s BMS (Battery Management System)
   

A more advanced controller – compatible with all battery types, including LiFePO₄ and lithium-ion.

• Efficiency: 90–98%
   
• How it works: Actively converts surplus panel voltage into extra charging current
   
• Performs well in low light and with high-voltage panels
   
• Costs more, but offers faster, smarter, and more efficient charging

 Leisure Batteries

Lead Acid vs Lithium LiFePO₄

Your leisure battery stores the energy produced by your solar panel. Here’s how the two main types compare:

The most common and budget-friendly choice. Includes sealed, AGM, and GEL types.

• Proven and reliable
   
• Can last for years with proper care
   
• Fully recyclable
   
• Slower to charge – limited to about 25% of the battery’s amp-hour rating
   

A newer, high-performance option for modern setups.

• Around half the weight of lead acid
   
• Faster charging – up to 80A (depending on BMS)
   
• Can be partially charged without damage
   
• Rechargeable thousands of times
   
• Longer lifespan than lead acid – often by several years
   

Summary:
Lithium costs more upfront but offers faster charging, lighter weight, and much longer recharge life. Lead acid remains a solid choice for simpler or lower-cost setups.
