WHAT EFFECTS THE PRICE OF SOLAR STREET LIGHTS?

There are numerous solar streetlights available on the market, with prices often varying greatly. So, what exactly causes such a significant price gap?

Light Heads

Light heads are generally very reasonably priced due to their high volume of production.  LEDs have completely dominated the global market and are currently estimated to be fitted to 60-70% of the world’s streetlights since the early 2000s. While most light heads remain affordable, some providers charge a premium for decorative designs.  Furthermore, whether a light head is adopted for highways also affects its price.  Providers consider this a premium benefit, certifying the light head’s ability to perform at the highest standards with balanced uniformity, therefore a higher price.

Solar PV

Solar panels are now mass-produced, making their manufacturing and supply chains incredibly efficient. This efficiency has also made solar panels more affordable.  However, the price difference arises from the style and type of solar PV. There are three types: monocrystalline, polycrystalline and thin-film.  Monocrystalline is the most expensive due to its higher efficiency in converting solar energy into electricity.  Polycrystalline falls in the middle regarding both efficiency and price. Thin-film is the least efficient and therefore the least expensive.

When comparing the total cost of solar lights, it’s important to consider the type of solar and overall performance.

Batteries

When purchasing a solar streetlight, always check the spec sheet, especially the battery.  It’s likely the most crucial component depending on size and type. We install Lithium Iron Phosphate (LiFePO4) batteries.  Different companies use various types, but LiFePO4 is the most common.  Battery size directly impacts performance; typically range from 250wh to 1400wh.  In the UK, batteries under 450wh often struggle due to our weather patterns.

Lamp Post and Bracket

Steel columns and fabricating in the UK isn’t a cheap process nor a massively expensive one. There are several fabricators in the UK who specialise in the production of street columns and based on the amount of development the UK undergoes every year, columns are accessible. The issue is that solar streetlights require custom columns to fit batteries in the base but also be fit for purpose to load the windage. Our columns are highways BSEN approved and finished in a painted finish, columns at this spec are more expensive compared to ‘off-the-shelf’ galvanised only columns.

There are other costs such as controllers, installation methods etc.

Always Compare Total Cost

Solar Street Lights appear to be inflated in price when just compared to a traditional streetlight, and that’s because there are more costs to consider when making the initial purchase for the light, solar PV, battery, controller etc. Whereas a standard streetlight is just a light head, steel column, and internal cables. But do not make the mistake of ignoring the cost of trenching, laying cables, feeder pillars, meters and then ongoing electricity bills.

Compare apples for apples, and you will weigh up that solar lighting columns are a smarter investment for the future.
