I have found that most people have a very rudimentary understanding of solar power and how it can work on a small scale for home applications. So I just wanted to put together a brief piece about how solar driveway lights work and the science behind it all. It’s really not that complicated, and it can make a world of difference for your energy bill.
Like most solar devices, asphalt driveways perth lights that are solar-powered are armed with photovoltaic cells which harness the sun’s rays. I won’t get into a deep discussion about photovoltaics here but it’s a reliable technology that has been in development for many years now. These rays are converted into usable energy and stored in rechargeable batteries until nighttime. Once the sun goes down a sensor in the unit will trigger startup, releasing the stored energy to power a number of LED bulbs in the light. The bulbs will glow all night (though some older models may weaken in power as the night wears on), shutting off once the sensor detects the light of dawn. Even if it’s overcast during the day these lights do a good job of capturing light energy during the day and putting off a steady glow at night.
If you’re not familiar with LED bulbs then you should know that they are the wave of the future because they are so cost-effective and efficient. In fact, they’ve become so advanced that researchers recently created a $3 LED bulb capable of lasting 60 years! These bulbs are real workhorses and I doubt that you’d need to replace any of them in your driveway lights for the foreseeable future.
As for the batteries, even though they are rechargeable by nature they will probably need to be replaced every couple of years to maintain maximum performance. I would say that most solar stone driveway lights will require anywhere from one to four batteries to perform, and they will usually be AA Nickel Cadmium or AA Nickel Metal Halide batteries. Nickel Metal Halide batteries (NiMH) are often considered more reliable in the long run though they might be more expensive to purchase.
The science of outdoor solar lights really isn’t that difficult, as you can see. It’s a rather straight-forward technology that researchers are making more efficient every day. You’d be wise to apply this knowledge and purchase a solar driveway light array for your home as soon as possible. Knowing all the benefits, why wouldn’t you?
