10 Best Solar Driveway Alarm System [Top Reviews and Buying Guide]

A solar driveway alarm is a device that detects trespassers or vehicles entering your property via its driveway. It works automatically like motion sensor lights. It alerts the property owners of an unexpected visitor or intruder. Its main purpose is to keep you and your family safe and secure from burglars throughout the day and night. A solar driveway alarm is energy efficient, eco-friendly and economical. You save a big buck off your electricity bills. It utilizes sunlight which is a free source of energy.

Solar driveway alarms are ideal for use in the countryside or rural areas, because of three reasons: firstly, houses are far apart from each other than in urban areas and their driveways are very long. Secondly, roads are often deserted and it is easier to mistake someone’s private driveway as the main road until you drive half a mile down and it dead ends into a house. Thirdly, the front lawns have high trees and thick vegetation which makes the driveway invisible from the top floor front windows.

How Does a Solar Driveway Alarm Work?

A solar driveway alarm has three components: a solar panel, a sensor and a receiver. A solar driveway alarm needs direct sunshine on the surface of its panel to produce the maximum rated power of the panel. The factors that determine the performance of a solar panel are equatorial direction, proper mounting angle, height, time and clear cloudless sky. If you are in North America or northern parts of Asia, you should mount your solar panel south, facing the equator to capture the maximum amount of sunshine. And if you live in South America, South Africa or South Asia, You should mount your solar panel facing the north towards the equator.

A sensor is the eye of this device. When it detects somebody or something enter its detection range, it transmits an audible signal to the receiver inside the house. There are three types of sensors:

1. Passive Infrared:

This type of sensor detects both people and vehicles as it senses heat. It is prone to false alarms caused by animals, birds, insects or wind.

2. Magnetic Probe:

It has a magnetic coil and detects metals entering into your driveway or moving by it. It can detect only cars or motorcycles and not humans or animals coming into your driveway.

3. Rubber Hose:

This alarm triggers when pressure is applied on top of the hose pushing up air.

The receiver is the device you place inside your house. It has a speaker with an adjustable and customizable volume.

Types of Solar Driveway Alarms

There are two types of solar driveway alarms:

1. Wireless solar driveway alarm:

It consists of three components: a sensor, a receiver and a transmitter. A transmitter sends the wireless alert signals to the receiver. Passive infrared sensor and rubber hose sensor are both wireless systems. Any physical obstacle in the way of the sensor and receiver can modify the maximum transmission range. Organic obstacles such as bushes, drywall, trees or wood will the only damper the strength of the transmission but will not stop the function. Metal is the worst obstacle. It can completely block wireless transmissions.

2. Wired solar driveway alarm:

Magnetic probe sensor is the only wired system. It is slightly costly as compared to wireless solar driveway alarms.
