Question 1

What are solar street lights?

Accepted Answer

Solar street lights are outdoor lighting systems powered by solar energy. They consist of a solar panel, LED light, rechargeable battery, and intelligent controller that automatically turns the light on at dusk and off at dawn.

Question 2

How do solar street lights work?

Accepted Answer

During the day, the solar panel converts sunlight into electricity and stores it in the battery. At night, the controller activates the LED light, drawing power from the battery. The process repeats daily without any manual intervention.

Question 3

How do I buy from Shinesun?

Accepted Answer

By enquiry rather than checkout. Every product page has a Get a Quote button — send us the model and quantity you need and we reply with a price, including bulk rates. There is no cart or online payment on this website; the order is agreed with us directly.

Question 4

What is the warranty on your products?

Accepted Answer

Between one and three years depending on the fixture, covering manufacturing defects. Most of our street lights carry two years, and our Premium series carries three. The exact term is stated on each product page.

Question 5

Do you install the lights?

Accepted Answer

No — we manufacture and supply the fixtures. Our lights are designed to be installed without an electrician, trenching or a grid connection, and most buyers put them up themselves or use a local contractor. If you would rather not, tell us your district and we will put you in touch with dealers and pole suppliers who do that work in your area.

Question 6

How do I install a solar street light?

Accepted Answer

Mount the fixture on a pole at the recommended height and angle the solar panel towards the south, clear of tree cover, buildings or anything else that shades it during the day. Shading matters more than most people expect: a panel in shade for part of the day charges for part of the day. Product-specific instructions are in our User Manuals.

Question 7

What pole height is recommended?

Accepted Answer

Our 40W, 60W and 90W street lights are designed for a 5 metre mounting height, and the 150W for 6 to 7 metres. Smaller garden, gate and wall fixtures mount much lower. Each product page states the height that fixture was designed for, and that figure is the one to use.

Question 8

How far apart should the poles be?

Accepted Answer

Roughly three times the mounting height, so about 15 metres for a 5 metre pole, and we would not go beyond 15 metres on residential or campus roads. Wider spacing leaves dark patches between poles rather than an evenly lit road. Send us the road width and pole positions and we will confirm the spacing before you order.

Question 9

What is a LiFePO4 battery?

Accepted Answer

LiFePO4 (lithium iron phosphate) is a lithium chemistry chosen for safety, cycle life and tolerance of Indian summer temperatures. Expect roughly 8 to 12 years of service life, against 2 to 3 years for the lead-acid batteries older solar street lights used. Every street light we make uses LiFePO4.

Question 10

How long do the lights last at night?

Accepted Answer

With a full charge, our solar street lights typically operate for 10-14 hours depending on the model and mode (full brightness vs. dimmed). Motion sensor models can last even longer as they dim when no motion is detected.

Question 11

What happens during the monsoon?

Accepted Answer

The battery is sized to carry the light through cloudy days on a partial charge, and the controller dims rather than cutting out. A long overcast spell will shorten the hours a light runs at full brightness. If your site sees a heavy monsoon, tell us when you enquire and we will recommend a model with more battery capacity for the same light output.
