Introducing our ‘Solar Honesty’ initiative  

We are proud to announce the launch of our exciting new Solar HonestyTM initiative. An initiative designed to educate specifiers on the broader considerations surrounding solar lighting solutions, empowering informed decisions that align with environmental and budgetary goals. 

While solar lighting offers a ‘greener’ alternative to fossil fuels, we recognise its implementation is only successful in specific scenarios. Tim Baker, Managing Director of Acrospire, emphasises the importance of approaching solar lighting with a critical perspective. “With this initiative, we want to educate, not put off specifiers,” he explains. “We encourage those considering solar to ask questions and challenge simplistic narratives. 

Achieving true sustainability in solar lighting requires solar honesty, or a critical perspective that considers the lighting solution’s entire lifecycle.” 

Specifiers must consider the four core pillars of ‘Solar Honesty’: Battery Type, Photovoltaic Panel Type, Recyclability, and Lighting Performance Requirements (levels and hours of operation), to understand the differences between solar and mains.  

Our commitment

We have been at the forefront of solar-powered street lighting installations in the UK for the past 6 years, delivering clean and energy-efficient solutions to local authorities, housing developers, and facilities managers. By leveraging the latest innovative solar technology, we have not only saved on installation costs but have also significantly reduced carbon emissions and promoted sustainable practices. 

Our commitment to ‘Solar Honesty’ extends beyond rhetoric. Tim explains, “We work with each client on a project-by-project basis and advise when or even if solar is suitable for their project. Solar will never make sense if a strap-cashed local authority has already invested in mains-powered luminaires and the supporting infrastructure. The upfront investment costs for solar are always going to be higher, as responsible manufacturer it is our duty to help specifiers on their journey to solar, even if that stops after the initial inquiry.” 

Battery Type  

We use LiFePO4 batteries, known for their longevity, they typically offer a lifespan of between seven and ten years, providing substantial improvements over traditional lead-acid batteries. This extended lifespan not only improves the cost-effectiveness of solar schemes but also significantly reduces their environmental footprint by lowering the frequency of battery replacements. LiFePO4 batteries also excel in efficiency, scoring 98% meaning that most of the stored energy is usable. 

Photovoltaic Panel Type 

Not all Photovoltaic panels (the bits that harness the power of the sun) are equal. We use Mono-crystalline, rather than Polycrystalline. The purer nature of the silicone in mono-crystalline results in improved heat management and low-light conditions which equals higher efficiency. 


However, the journey to true sustainability continues after installation. Through recyclability by design, we demonstrate our dedication to responsible waste management, actively encouraging the recycling of solar panels and batteries used in our projects.

Its important specifiers know what they are buying, and they should be able to discuss all of these topics with their chosen manufacturer to ensure their solar investment lives up to the claims. So, let’s embrace transparency, challenge assumptions, and work together towards a greener future.
