When evaluating solar cells, commonly referred to as photovoltaic (PV) technology, for commercial lighting applications, the central question is whether the technology is sufficiently mature for widespread implementation or not. Historically, the primary concern was whether solar systems lighting could reliably capture and store enough energy to operate throughout the night and recharge effectively during the following day.
With today’s technology, solar powered LED lighting is commercially practical and widely deployed today. Its suitability, however, depends on the application. It performs particularly well in various outdoor and off-grid environments, while certain operating conditions still require careful evaluation.
Our engineering team at NaturaLED have done extensive research and testing to develop a better modern solution for next generation of solar powered commercial lighting fixtures. Our SPFX Area Light and Pathway series were designed to answer the long-awaited needs for off-grid applications that will cut the need for complicated and expensive installation costs.
Before we dive into our SPFX Solar Powered lighting fixtures, let us see the challenges and considerations of this technology. Although the technology is commercially ready, performance is still influenced by site-specific conditions. Here are some of the challenges and considerations:
Sunlight dependence. Performance depends heavily on:
-Sunlight/solar exposure. Cloudy & rainy/snowy conditions can reduce efficiency.
-Shading (urban density, trees, etc.)
Proper system design, including panel sizing and battery storage capacity, is essential for reliable performance.
Higher upfront cost per unit.
-Systems can cost more initially than grid-connected lighting.
-However, incentives (tax credits, rebates) and no electricity cost often offset this cost.
These challenges have brought to our attention developing and introducing the latest technology in battery storage and solar cell technology.
Our Solar Powered LED lighting fixtures are equipped with the latest battery technology material of Iron Phosphate Lithium LiFePo4. This material is proven to deliver long life optimization, better energy utilization, environmentally friendly iron phosphate materials, and highly stable (low fire risk) operation. Our battery comes with 3yrs warranty proving over two thousand cycles @80% DOD operation time.
Besides offering the highest quality rechargeable battery materials, our SPFX solar powered lighting series use selected Grade A Mono-Crystalline solar panel materials. This material delivers a whopping 20.4% efficiency and is ideal for solar lighting systems that provide maximum reliability, long lifespan, and performance.
Key Advantages.
Besides the challenges, solar powered LED lighting still offers more advantages such as:
- Low Energy & Operating Cost.
• They are powered by sunlight → no electricity cost.
• Requires no trenching, wiring, or grid connection.
• Operating costs are stable, with no effect on energy price increases. - Low Installation Cost.
• Fast, standalone installation.
• No need to dig for underground wiring. Ideal for retrofits in remote areas such as national parks and off-grid areas.
• Minimal site disruption. - Light Quality & Efficiency
• Remarkably high efficiency (lumens per watt).
• Instant on, full brightness.
• Programmable to dim with motion/occupancy sensors.
• Selectable CCT (2200K – 5000K) to meet customer’s requirements.
• Directional light → better for pathways (less light spill). - Maintenance & Lifespan
• Long lifespan (LED life: >50,000 hours).
• Long Batteries life (5–10+ years, depending on type).
• Minimal maintenance, there are no bulbs to replace. - Reliability
• Works during power outages (off grid).
• Good reliability.
• Best in sunny environments. - Environmental Impact
• Zero emissions during operation.
• Uses renewable energy.
• No hazardous materials like mercury.
Solar powered LED lighting technology has matured and is practical solution for many modern commercial applications because they can offer lower lifetime cost, energy savings and independence, easier installation, better efficiency and light quality, and environmentally superior.
