Do solar fixtures require exposure to direct sunlight?
While exposure to direct sunlight will charge your solar fixtures at a faster rate and enhance their performance, it's not a necessity. They’ll still charge on a cloudy day, just at a lower voltage.
Can they withstand exposure to the elements?
Solar fixtures are made for the outdoors and can certainly withstand exposure to the elements, especially in South Africa where our weather is fairly mild. They’re generally crafted from durable plastic and rust-proof metal and typically have a waterproofing rating of IP65. With that being said, extremely windy conditions can cause hanging fixtures to fall off their hooks. In this case, it is better to remove the fixture and bring it indoors for safekeeping until the wind subsides.
Are there batteries in solar lights?
Yes, solar fixtures consist of a solar cell, Ni-Cad rechargeable battery, LED light and photoresistor. They harness the power of the sun during the day, storing that energy in the battery to be used at night. The photoresistor detects a change in the level of light, which in turn activates the battery and turns the LED on.
What are the benefits of outdoor solar lighting?
Solar light fixtures offer a multitude of benefits:
- They’re economically friendly.
- They’re better for the environment.
- They're easy to install and move around
- They’re simple to maintain.
- They’re safe for environments with pets and children.
- They’re reliable during periods of load shedding
How long does outdoor solar lighting last?
If you take good care of Ni-Cad rechargeable batteries, they should have a lifespan of about two years. LED bulbs will offer up to 30,000 hours of illumination. To get the most out of your fixtures, regular maintenance is essential. Use a damp, lint-free cloth to gently wipe the solar panel clean at least once a month. Once the dust, dirt and grime is removed, wipe it with a dry cloth.
How many hours of illumination do they offer after fully charged?
The average fixture offers between 8 to 12 hours of illumination.
What causes decreased performance of a solar fixture?
The culprit may be reduced sunlight hours. Turn the fixture off and allow it to charge for two to three sunny days without using it. This will allow the battery to recharge and operate as normal. If this does not work, it could mean that the battery needs replacing. This sometimes happens after around two years.
