We recently had an inquiry about solar security lights and would like to share that information with all you solar enthusiasts and those who simply want to get security lighting up and running quickly. So, here it is…..
Letter to inquirer (abbreviated):
We have been getting numerous inquiries regarding rechargeable batteries and solar garden lights, so we are here today to help you determine some possible solutions to get your lights working properly and effectively. Rechargeable batteries are one of the most important components of solar garden lights and are a simple issue to address. Here are some likely scenarios:
1. Solar lights aren’t staying on after sunset. This may be due to a few issues in and of itself.
A) The rechargeable battery isn’t making a proper connection. Somewhere along the circuitry line in your light there is a break or bad connection. If the feed of electricity that is supplied by the solar panel during the day isn’t getting through, then the battery won’t charge to its full capacity, if at all.
B) The rechargeable batteries are getting a charge, but they aren’t storing it as they should. This could be due to a faulty photoresistor that “thinks” it is dark out, thus running the LEDs during the day and using up charge from the rechargeable batteries, leaving only a residual light of a few hours after sunset. This appears to be the most common culprit when it comes to a solar garden light “eating” its way through your rechargeable batteries.
C) The batteries are at the end of their life cycle. Rechargeable batteries typically last for about 2 years of daily use before they need to be changed out and recycled. One thing to remember about rechargeable batteries, the ones listed as Nickel Cadmium (NiCd) will acquire a “memory”, wherein the battery remembers its last capacity charge and only charges to that limited capacity on following charges. In other words, if you have NiCd rechargeable batteries and they only charge to half their capacity during a cloudy period, then the following full sun days will only charge to the lower cloudy day capacity. They still charge, but not to the level you may have seen when you first installed the batteries and it was sunny out during their initial charges/uses. On the other end are the Nickel Metal Hydride rechargeable batteries which cost a little bit more but don’t acquire the “memory” effect as compared to their NiCd cousins. And do make sure you have the proper type of battery in your solar lights. There are Lithium Ion rechargeable batteries on the market, but they are specified for their particular device. They generally produce a brighter light (as the LED is able to handle the power) and can fry out the circuitry on a device that is specified for NiCd or NiMH batteries. Just be sure you use the right ones!
2. Solar lights aren’t going on at all at night. This may be a result of the above points, or it could be that the photoresistor isn’t working properly (if at all). The photoresistor will “tell” the LEDs to activate at night (this is what is referred to as an Auto On/Off feature, so that you don’t have to manually turn them on and off every night). If the photoresistor isn’t doing its job, then neither will any other component of your solar garden lights.
3. Solar lights go on/off intermittently without me doing anything to them. This could be the result of a faulty switch and/or photoresistor. If it is the switch, then you may want to wiggle the switch to see if you can get it to where the connection is made and the light stays on. This issue happens, but not as frequently as battery issues.
4. Solar lights won’t go on at all, even after I put in new rechargeable batteries. If this is the case and wiggling the switch doesn’t work, it could be that something in the circuitry has failed. It could be the photoresistor, it could be that the solar panel is fogged over to the point of no return, or that rust has overtaken the internal circuitry. If this happens, it may be best to recycle the old solar lights and replace the entire unit. If you are electrically/mechanically inclined and have the resources for replacement parts, this may be along your lines of troubleshooting. More than likely the solar light will need to be discarded properly and replaced with a newer model. Most solar lights on the market are made to be affordable, so things will go wrong with them (the old adage, “you get what you pay for”).
Remember not to be discouraged by solar garden lights. They have their issues, but this is not commonplace when compared to their advantages. They require no electricity, are quite simple to put almost anywhere around your home and garden, are safe for kids and pets (no 120 Volts of electricity by which to be shocked), are relatively affordable and most importantly, they get you that much more off the conventional electricity grid. We want customers to have the added satisfaction that they are not contributing to the continuing cycle of oil and nuclear extraction/waste when customers simply want to add lighting elements to their homes and gardens. Solar garden lights are the solution and we are here to help you achieve that goal.

We recently received an inquiry regarding photoresistors and solar lights. We thought it was an interesting topic, so we decided to share it with you today.
Inquiry: Please help. I have solar garden lights. One clearly has a photoresistor while others do not have a photoresistor. They all turn on at dark, off when there is sun. The model with photoresistor has 2 wires coming from solar cell and two wires coming from photoresistor. Model without visible photoresistor has only two wires coming from solar panel. How does this work without a visible photoresistor. Thank you.
Response: Hello. We checked with one of our test lights and found that the photoresistor was integrated into the solar panel. It was not easily seen on the face of the panel, but once we disassembled the light we were able to determine that this was the case. There was also only one set of wires (black and red) that fed into the solar panel from the circuitry board.
This may or may not be an advantageous placement for the photoresistor. From what we have experienced, it is leaning toward “not”. These lights gave out sooner (after about a year and a half) than other lights, so we no longer carry them on our website. It may just be an engineering matter that is not yet perfected.
Hopefully this information helps with your inquiry. If the light is working, then that is a good thing. If it is not and you are looking to replace/substitute the photoresistor, then it may be best to recycle/discard the light and replace it with a whole new light. Replacing a photoresistor will take some engineering/electrical know-how and may be more trouble than it’s worth.
Thank you and we appreciate your inquiry.

Now, why is all of this important, you may ask. Well, in a nutshell, the photoresistor tells your light when to turn on and off. Turning on and off is also important for your batteries. An improperly-working photoresistor (also known as a photocell) may bypass the “off” mode and have your lights “on” constantly. This means that the battery is being used during the day and will not retain enough charge in the night to cast light through the darkness as intended. In the worst-case scenario, a photoresistor that doesn’t work at all may not “tell” your lights to go on at night, leaving you frustrated and disenchanted with the whole thing.
So, when your solar lights aren’t working properly (or at all), a little troubleshooting may reveal that the photoresistor is bad. In this case, it is best to replace the light (if under warranty) or to buy a new one altogether. In most cases, the photoresistor will work properly and the culprit may be a bad battery or that the solar panel isn’t getting enough sunlight during the day.
One of our new lights has what we can determine is one of the most efficient when it comes to circuitry, solar collection and as related to this post, photoresistors. The tiffany-style mosaic glass solar light is top of the charts. We charged it for one day and it was able to light up indoors for two nights (skipping the second day of charging) with no problem. And, it is quite attractive and versatile (not many lights can be put indoors on table tops.) It’s worth checking out.
Enjoy your day (and night) fellow solar lighters.

It is so frustrating. What can we do when something breaks down? We spend hard-earned money on things and they just go kaput after a couple of months, sometimes even less. Aren’t they supposed to last longer? All the time and energy spent to make the thing, and it just calls it quits for no apparent reason whatsoever. Well, there may be underlying reasons. It could be a quick fix and inexpensive solution that will get your things back up and running. We received a question recently regarding a fellow solar light user and would like to share it with you, in case you are experiencing the same problem:
Hi solar light expert,
I just bought my set of solar lights and been using them for about three months now. Its the type with 8 lights and one solar panel. I’ve been noticing that they are really dull recently. They still light up but is very dull compared to how used to light up when new. Its only been a few months since i bought them. Could it be the battery?
Thank you in advance!
It could be that (as you mentioned) the batteries are no longer working at their full capacity. Sometimes when a light is purchased, a span of time has passed since the battery was initially charged, what with time on the shelf at the store, shipping, etc. Typically batteries are pre-charged in store/on-line bought solar lights. The type of battery used also will have an effect on this lag time between charge and use.
If your light uses Ni-Cd (Nickel Cadmium) batteries, they will acquire a “memory” for their storage capacity and overall life. These are the least expensive rechargeable batteries on the market for solar lights. By memory, we mean that if the battery is charged to half its capacity by a short charging cycle (cloud cover, half-day’s charge, etc.), then the battery will “think” that this is the peak capacity it can carry and will use that as an optimum the next time it charges, even if the solar light is in a full-day’s sun in following days.
If your light uses Ni-MH (Nickel Metal Hydride) batteries, they will not be affected by the “memory” problem as with their Ni-Cd cousins. These will charge to their full capacity when the sun is in their favor. On cloudy days, they will charge to partial capacity. But once Helios rolls through the sky again, they peak at their expected charge capacity. These batteries are a bit more expensive (albeit, not a lot compared to others out there), but are a better alternative that can be used in Ni-Cd accepting solar lights. Note: Do not mix the batteries together (if the solar light uses 2 or more), use either all Ni-Cd or all Ni-MH in your solar lights.
A third alternative are the Lithium Ion batteries. These are the batteries in the brick house (think of the Three Little Pigs) for small-scale solar lights used around homes and gardens. These put out a higher voltage and typically produce a brighter light. But, and this an important point, they are not to be used in solar lights that require Ni-Cd/Ni-MH batteries. Lithium batteries will fry your Ni-Cd/Ni-MH solar light LEDs in a matter of seconds! We’ve tested this and there is no turning back once the damage is done. Well, there is a fix, but you will need some knowhow to change the circuitry/LEDs as well as the parts. It’s not worth the risk, so be sure you replace your batteries with proper specifications.
A fourth battery on the market is the Lead Acid battery. These are not your typical garden solar light battery and are another ball of wax, but generally produce the brightest light with regard to garden and landscape solar lights. They have the highest Voltage output and store more energy, therefore are the most expensive in the family to replace.
That all being said (there actually could be more, but we’ll suffice with the above), another problem with the low/quick output of light from your solar lights could be that the solar panel is either obstructed with dirt/dust or that it is partially covered in shade during the day when it should be getting full sun (they will typically need at least 6 hours of full sun to give a good return at night). The final problem could be the quality of the components (circuitry) of the solar lights. A better engineered product will usually last longer (years) than an inexpensive product. Some solar lights on the market are very inexpensive, but with that comes low light output, low battery life and eventual breakdown of the system.
We hope this helps with your question. Best of luck with your solar lights. Let us know if you have any more questions with your set. We are here to help and inform.

So, don’t worry. There is a reason that your solar lights may not be working properly (or at all). We are here to help walk you through the fix and find a solution. It may be a silly expression, but it all works out in the end.
The Solar Bollard Lights have found their way poolside, again showing their diversity in locale. Not only do they make great lights for intimate patio settings, they also illuminate larger areas in open spaces by a pool in rural San Diego County.
Mounted to a 2 x 10 board, they are sturdy enough to withstand windy conditions while being doused with water during swimming exercises. With an aluminum body that is powder-coated in black, they quietly gather energy during the day in order to illuminate with elegance at night.
Sure, they are one of the more expensive solar lights on the market, but the payback is returned in no time at all. One, they are off the grid (you know, no electricity to fuss with or pay for). Two, they are totally safe around kids, pets and by pools (again, no electricity to shock your family or friends. Nobody wants that.) Third, you are not letting the utility companies bill you to illuminate your landscape, ever! Fourth, no black outs. And if there is, you can just bring your Solar Bollard Light indoors and play that crucial hand of Texas Hold-Em! And finally, they are just plain cool and make perfect sense (see above).
The power is yours (literally). Going solar today is a reality we live in and can all enjoy.
