Does the solar light turn on and off automaticlly?

SunMaster's solar controller uses a photocell and/or timer to control when the light will turn on, when the sun goes down, and to turn off

when the sun  comes up.  The photocell detects when the sun comes down and when the sun comes up again. SunMaster can make the

lamp last anywhere from 8-14 hours, and this varies on the customer's needs.

What happens if there are cloudy days?

Electrical energy is stored in the battery each day, and some of that energy is used to operate the light at night. Generally, we design your

system so that the battery will operate the light for five nights without charging. This means that, even after a series of cloudy days, there

will be plenty energy in the battery to power the light each night. Also, the solar panel will continue to charge the battery (although at a

reduced rate) even when it is cloudy..

What information needed for design?

• The site location to check the radiation date.
• The road type and the brightness requirement.
• The backup days requirement.
• The lighting hour requirment.
• The existing lamp power. (If for retrofit project)

What testing labs have certified the quality and distribution of light?

SunMaster uses only third-party independent test labs that have been approved by the US Dept. of Energy to test the SunMaster LED

luminaires and generate the resultant IES files

What is your warranty terms?

• 3years standard. 8 years negotiatable.

How to Choose a realiable solar street light supplier?

1.System Warranty: The manufacturer’s warranty has a lot to say about their systems. If the system only has a year warranty, chances are,

they do not expect their system to last very long in the field. Look for something that has at least a five year warranty, or the components

broken out for separate warranty information for individual components. This will ensure that the system will have a long life and you are

dealing with a company that will stand behind their product.

2.Longevity: How long is each component meant to last? Warranty is great to understand how long the manufacturer will ensure their

system components will last, but what about lifecycle. Make sure to receive not only warranty information, but lifecycle and longevity

information. If a component needs to be replaced every year, this will waste time and money maintaining the systems.

3.Proven Field Installations:  How long has the company been in business? Are there field installations over five years? Ten years? There

are many companies coming into the market today that have only been in business for a year or two. Understanding the difference of a

company that has proven field installations over a company who is new to the market can help ensure that the systems are built to last for

many years. Solar has a life span of 25+ years, but if everything else degrades and falls apart, then the premium for solar power is wasted.

Systems should be able to operate in the field for over 20 years with very little maintenance.

4.Specifications Met:  Light level requirements, nights of autonomy, plenty of solar power and operation schedules all are parts of the

design of a reliable solar outdoor light. All four factors must be met to the highest standard to ensure that the light will operate as required.

Having a lighting plan completed to ensure that light level requirements are met is the first step to making sure that the purchase is from a

reputable company. If the autonomy and solar power is not completely understood, calculations provided by the manufacturer can show

exactly how the system is configured.

What is the typical maintenance schedule for a solar lighting system?

• There is no regular maintenance required for a solar lighting system. However, it is helpful to keep the solar panels clean, especially
• in a dusty climate.

Do I have to charge the Batteries?

• Batteries are shipped 85% charged. The batteries will be at 100% charged within two weeks of proper operation.
