🔥 How the Sol+Guard 500M 180 Works Differently
The Science of Maximum Solar Heating
Most pool covers focus purely on heat retention. The Sol+Guard 500M 180 does something smarter—it actively heats your water while also keeping that heat locked in.
The Dual-Action Technology:
- Translucent UV Transmission (Heating Phase)
- Unlike opaque covers that block sunlight, the Sol+Guard’s translucent material allows UV rays to penetrate deep into the water
- GeoBubble air pockets act as thousands of tiny magnifying lenses, concentrating solar energy
- Can raise water temperature by up to 8°C on sunny days
- Effectively gives you free solar heating—no electricity required
- GeoBubble Insulation (Retention Phase)
- 500-micron thickness creates a thermal barrier
- Unique patented bubble shape (not round like traditional covers) provides 25% longer lifespan
- Prevents heat from escaping overnight or on cloudy days
- Reduces heat loss by up to 75%
- Enhanced UV Protection Layer (Durability Phase)
- The “180” formulation includes an extra protective layer designed for UV exposure up to 180 kLys/yrs
- Standard covers (140 formulation) can degrade in hot, sunny conditions
- Perfect for UK’s increasingly sunny summers and pools in direct sunlight
- Maintains performance year after year without degradation

🌍 Understanding UV Protection: Why the “180” Matters
The Sol+Guard comes in two UV formulations designed for different climate zones:
Sol+Guard 500M (140 Formulation)
- Suitable for areas receiving up to 140 kLys/yrs UV exposure
- Perfect for standard UK conditions and partially shaded pools
- The original, reliable solar heating cover
Sol+Guard 500M (180 Formulation) ← This Product
- Engineered for areas receiving up to 180 kLys/yrs UV exposure
- Enhanced protective layer prevents UV degradation
- Ideal for:
- Pools in full, direct sunlight throughout the day
- Increasingly sunny UK summers with high UV index
- Southern England and sunnier regions
- Pools without natural shade from trees or buildings
See the UV Map: Download the UV Protection Guide to understand UV exposure levels across the UK and determine which formulation is right for your location.
Why this matters: Standard covers can become brittle and degrade when exposed to prolonged intense UV. The 180 formulation adds years to your cover’s lifespan while maintaining peak performance.

❓ Frequently Asked Questions
Installation & Usage
Q: Which side of the cover faces the water?
A: Bubbles face down (toward the water). The air trapped in the bubbles is heated by the sun, and placing them directly against the water ensures maximum heat transfer.
Q: Can I run my pool pump with the cover on?
A: Yes! A properly secured Sol+Guard cover won’t affect your pump’s circulation. Many pool owners leave the cover on while filtering to maximize heat retention.
Q: How do I manage the cover? Is it heavy?
A: The 500M material is lightweight and easy to handle. For larger pools, we recommend a pool cover roller system for effortless installation and removal. Rollers available separately.
Q: Can I use this cover in winter?
A: Solar covers aren’t designed for winter use in UK conditions. We recommend switching to a purpose-made winter cover (October-March) and storing your Sol+Guard properly. This protects your investment and ensures it’s ready for next season.
Performance & Compatibility
Q: Will this cover completely eliminate the need for a heater?
A: No. While the Sol+Guard provides significant solar heating (up to 8°C increase), you’ll still need a reliable heat source (heat pump, solar heater, or gas heater) for consistent comfortable temperatures. The cover makes your heater far more efficient and reduces runtime by 60-70%.
Q: How much can this really heat my pool?
A: Temperature increase depends on:
- Sun exposure (hours of direct sunlight)
- Pool size and depth
- Ambient temperature
- Starting water temperature
In optimal UK summer conditions, expect 4-8°C temperature increase over several sunny days. The bigger benefit is maintaining that temperature overnight rather than losing it.
Q: Does it work with salt water pools?
A: Yes! The Sol+Guard is compatible with all pool types: chlorine, salt water, bromine, and mineral systems. The enhanced UV protection actually helps it resist chemical degradation.
Q: How does this compare to a pool heater alone?
A: They work together. Your pool heater brings water to desired temperature; the Sol+Guard maintains it with minimal heater runtime. Together, they create an efficient system where:
- Heater runs 60-70% less
- Pool reaches target temp faster
- Temperature stays stable overnight
- Your energy bills drop dramatically
Warranty & Durability
Q: What does the 6-year pro-rata warranty cover?
A: The warranty protects against material defects and degradation under normal use. Pro-rata means coverage decreases proportionally over the warranty period. Important warranty conditions:
- Valid in UK & Ireland only
- Void if pool water temperature exceeds 29°C
- Void if SPATA standards for chemical and TDS levels aren’t maintained
- Proper storage during winter required
Q: How long will this cover actually last?
A: With proper care and storage:
- GeoBubble technology: Lasts 25% longer than traditional bubble covers
- Expected lifespan: 6-8 years with proper seasonal storage
- UV protection: The 180 formulation significantly extends life in sunny conditions
Care tips for maximum lifespan:
- Store properly during winter (dry, away from direct sunlight)
- Maintain proper chemical balance (follow SPATA standards)
- Keep pool water below 29°C
- Rinse cover periodically to remove chemical buildup
Sizing & Customization
Q: What if my pool isn’t a standard size?
A: We offer bespoke made-to-measure covers for any pool shape or size. Use our solar cover calculator to input your exact dimensions, or contact our team for assistance.
Q: Should I order the exact size of my pool or larger?
A: Order the exact size or slightly larger. The cover should extend to your pool’s edges to maximize coverage. Our team can advise on optimal sizing during your consultation.
Q: Do you make covers for irregular-shaped pools?
A: Yes! We can create custom covers for L-shaped, kidney-shaped, or any irregular pool configuration. Contact us with your pool specifications for a quote.
