WHAT TO LOOK FOR WHEN CHOOSING A
SOLAR STREET LIGHT:
Three key factors have to be
considered when selecting a solar street light:
RELIABILITY
Assurance that the light is going to
work all night long, every night.
01
PERFORMANCE
Will this product deliver strong and
consistent light output.
02
AFFORDABILITY
Is this an affordable solution that
fits within your budget?
03
RELIABILITY
The reliability of a solar street light is subject to a few key components. The majority of
solar street light failures are caused by the limitations of one or more of these
components.
LOWER RELIABILITY
HIGH RELIABILITY
Battery Capacity
Insufficient Battery
Capacity
Large Battery Capacity
There isn't enough battery
storage to keep the solar light
run all night. The light most
probably has to be dimmed after
a few hours to save power.
Enough battery capacity storing
power for 2-3+ days of sustainable operation during prolonged
overcast weather.
Inadequate Solar Panel
Adequate Solar Panel
Improperly sized solar panels will
not enable solar harvesting to
generate enough electricity for
the light to run all night without
dimming.
Solar panel size should be 3-10x
of the LED module power output
depending on the application. A
panel size of 10x the LED power
could be a common thing for
critical operation in the worse
case scenario.
Cheap Housing (Plastics)
Quality Housing (Metal)
Poor quality ABS or polycarbonate plastics will deteriorate when
exposed to the exterior elements
for an extended period of time.
Specially treated aluminium in
combination with a marine grade
coating or galvanised finishes,
and high quality stainless steel
accessories, will all be reliable
with long term sun exposure.

01
PERFORMANCE
Solar street lights are frequently marketed with exaggerated or misleading power
output figures. Don't buy a product based solely on the advertised wattage or
power output. This is only one of the factors that will determine how a light will function
once installed.
LOWER PERFORMANCE
HIGH PERFORMANCE
LED Quality
Low Quality LED
High Quality LED
Low quality LEDs consume much
more power to deliver the same
amount of light output. Thus it
requires larger battery capacity
as well as bigger solar panel to
support. This case will significantly increase the Total Cost of
Ownership (TCO)
High quality LEDs are more
efficient to generate the same
amount of light using less power.
It is recommended that the
lumens per watt be greater than
180LM/W.
Fixed Lens of Inferior PC
Interchangeable Optics
Generally factory fitted and do
not provide optics type options or
allow the light distribution to be
controlled as effectively
Optical grade plastics that
improve light distribution. These
lenses can also be changed to
provide the optimum light
pattern for a wide range of
applications.
Limited / No Options
Custom Adjustments
Generic operating profile set by
default at the factory. Does not
offer any timer settings or the
ability to adjust or control the
power output.
Customizable operating profile,
run times, power output, and
advanced power scaling to ensure
continued operation in the worse
case scenarios of bad weather
conditions.

02
AFFORDABILITY
The lowest cost product is unlikely to
be the most affordable option in long
term. Whenever you pay less upfront,
you end up paying more over the lifetime
of the project when you add up replacement costs of new fixtures and include
time, labour and equipment hire.
The Bitterness of Poor Quality
Remains Long After The Sweetness of
Low Price is Forgotten.
LESS AFFORDABLE
AFFORDABLE
LED Quality
Installation Process
Involved
Simple Installation Process
Mains powered lighting installation necessitates the involvement
of several workers including
traffic management, trenching,
and cable laying, as well as an
electrician to connect.
Installation process that requires
less technical persons on site and
helps you avoid the expense on
concrete cutting, cabling and
trenching for mains power
Low Cost – Means Frequent Replacement
Higher Upfront Cost –
No Replacement Required
Replacing a street light every few
years does not make financial
sense. Equipment rent combined
with the environmental cost of
low quality products should
always be considered before
purchasing.
Requires almost no maintenance
for 5+ years. Replacement parts
such as batteries are available
and stocked locally.
(TCO) Total Cost of Ownership
should prevail the upfront
expense.
Limited / No Ongoing
Support
Local Technical & After
Sales Support
If you don't have support means
paying an electrician if you
encounter a problem. Replacement parts could also be difficult
to obtain, meaning you may end
up replacing the entire fixture.
Technical and ongoing support
provided at no additional costs
under warranty. Local support
team available to provide assistance.

HOW TO BUY SOLAR STREET LIGHTING
IN A NUTSHELL
WHAT TO DO
The best way to start purchasing a solar street light is to directly contact a
qualified solar street lighting supplier and request a quote. Obtaining multiple
quotes for comparable products will be the most effective way to find the most
competitive pricing.
TIP:
When selecting a supplier, consider one that is focused on quality and offers ongoing technical
support.
Dealing directly with a manufacturer has a significant advantage as they generally provide better
service and ongoing support as opposed to just being a reseller of internationally sourced products.

5-POINT SOLAR STREET LIGHT
‘BEFORE YOU BUY’
CHECKLIST:
As a leading world-class solar street lighting manufacturer for over 10 years, Hiorange
Lighting have built up an extensive understanding of what makes a solar street light
reliable, affordable & high performing. Before you buy, ensure the solar street lights you
are considering check the following 5-point checklist:
Capacity To Run All Night During Winter
This is a calculation and not an estimate. A supplier should conduct an location audit with
simulation report to determine if a product has sufficient battery capacity to run all night
without dimming during the worst weather conditions and the darkest winter months.
Components Are High Quality & Durable
Physical outer structure and housing material are made of higher grade materials or
stainless steel to withstand heavy duty in case of worse scenarios. High quality inner
components such as LEDs and optical Lens ensure reliability and performance.
Low TCO (Total Cost of Ownership) & Investment
Requires almost no maintenance or replacements for 5+ Years. Replacement parts are
available and stocked locally if required.
While the low quality solar light most probably requires frequent replacements and as a
result the TCO would be much higher than the good quality solar lights.
Ongoing Support & Warranty
From initial installation to ongoing technical and maintenance support, the supplier
provides full process support.
Compliance With Lighting Standards & Regulations
Solar street lighting should meet all applicable standards. These standards are set
regionally by government and industry bodies to ensure the illumination of infrastructure
is nationally consistent.

Interestingly, the hidden (invisible) cost of poor quality are often much greater
than the visible cost that organizations track.
