Solar Lights Guidelines On Buying

Solar Lights

We have compiled a list of FAQs that many customers have brought to our attention throughout the years that will help you understand how solar lights work and which solar lights are right for your application.  Let’s get started!

Solar Lights Batteries

Why do solar lights require batteries? How do solar lights work?

All solar lights require rechargeable batteries in order to store the solar power collected by the sun during the day to power the light at night. During the day the solar panel will recharge the internal batteries in the solar light so there is ample power in the evening for the lights to illuminate.

Will I need to replace the rechargeable batteries in my solar lights? 

Yes. Most of our solar lights use AA rechargeable batteries, which can be purchased at any hardware, or electronics store that sells batteries. Most rechargeable batteries should be replaced every 18-24 mos.

LED Solar Lights

What are LEDs? How do LED solar lights work?

LEDs are a super energy efficient light source also known as light emitting diodes. LEDs are actually semiconductors that emit light when voltage is applied. LEDs are used in almost all electronic devices today such as digital watches and cell phones.

What makes LEDs super energy efficient is no heat is needed in order for the LED to illuminate. With standard incandescent Edison type bulbs 90% of the power consumption is used or wasted burning the filament.

LEDs emit no heat and since they are so efficient they last upwards of 50,000 hours. The key benefits of buying LED solar lights are: You will never need to change the bulbs and your solar lights will last for years and years.

Since they consume such little power LED solar lights can stay illuminated all night long with a small battery source pre-installed inside your solar light.

Lastly, LEDs emit an extremely intense and targeted light beam that produces a natural light color closer to natural daylight. Solar lights from Earthtech Products are available with cool or warm white LEDs.

Weather Conditions and Solar Lights

Do my solar lights require direct sunlight?

Yes. Solar lights do require direct sunlight. Solar lighting is site and weather sensitive. The panel may be adversely affected by anything that obstructs sunlight or other surrounding lighting that may interfere with the solar panel. Panel recharges with daylight.

The light output will perform under most conditions however; light intensity may be affected by available Sunlight. While a solar light not receiving direct sunlight may perform for a few hours a night in order for your solar lights to operate at maximum efficiency for the entire night they should receive direct sunlight daily.

Will my solar lights work in freezing temperatures?

Yes. Our solar lights are designed to be completely weather and waterproof. For our customers living in cold northern climates you should expect your solar lights to function as usual however, keep in mind available sunlight in winter months is reduced so your run time or on time for your solar lights may be reduced as well.

Solar Lights and Photocell Sensors

Do my solar lights have an on/off switch? Will my solar lights turn on automatically at night? 

Yes. Solar lights do have an on/off switch. When placed in the on position the photocell sensor will be active and your lights will come on automatically at night and also turn off automatically at dawn. When your solar lights are in the off position the batteries will still charge during the day but the photocell sensor will not be activated so the dusk to dawn operation will not be activated and your lights will not illuminate until put back into the on position.

Solar Lights Maintenance and Installation

Are solar lights difficult to maintain? What is involved with installing my solar lights?

The beautiful thing about solar lights and what makes them so appealing is the absence of maintenance and ease of installation. Many of our customers choose solar outdoor lights because they do not want to hire an electrician to hard wire lighting at their home or business.

Another key factor is the energy efficiency and energy cost savings of solar lights vs. hard-wired lighting. Since solar lights require no electrical grid power and are powered exclusively from the sun there are no electricity costs involved and no complicated wiring is required.

As far as installation is concerned, Ground Stake Solar Lights are simply staked in the ground and they are ready. Now that beats the headache and costs associated with hard wiring lighting.

As far as maintenance is concerned, they’re a few simple factors to keep your solar lights functioning at there best. Here they are: Change the rechargeable batteries every 18-24 mos. or as needed and keep the solar panel and photocell sensor clean.

By keeping the solar panel clean you will be assured maximum solar cell efficiency. By keeping the photocell sensor clean the auto dusk to dawn operation will function and not be tricked into thinking its dark out during the day because the cell is covered with dirt.

In this event the light will turn on during the day (thinking it is night time) and the batteries will be discharged leaving no power left to illuminate your solar lights at night.

You should also install your solar lights in locations that will not be obscured by trees or nearby street lamps or other lighting that will trigger the photocell sensor to think it’s daytime during the evening hours. In this case the solar lights will not turn on as the photocell sensor light on position is triggered by darkness.
