How Solar Energy Works

Solar energy works by harnessing the power of the sun to generate electricity. This process begins with solar panels, which are made up of photovoltaic cells designed to capture the energy from the sun’s rays.

When sunlight hits these cells, it excites the electrons within them, creating a flow of electricity. This electricity is then sent to an inverter, which converts it from direct current (DC) to alternating current (AC), the type of electricity used in homes and buildings.

The energy generated by solar panels can be used in a few different ways. It can be used immediately to power the electrical devices and appliances within your home or stored in batteries for later use.

Alternatively, excess energy generated by solar panels can be sold back to the power grid, allowing homeowners to earn credits or money for the energy they produce.

How a Homeowner Decided to Go Solar: A Real-Life Case Study

A home solar power system can be used to run a wide range of appliances in your house once you get it installed.

Depending on the size, power output, and configuration of your system, you can use it to run big-ticket items such as refrigerators, washers and dryers, dishwashers and microwaves – even large flat-screen TVs! You may also be able to run smaller appliances such as computers, lights, home security cameras, etc.

Many homeowners succeeded in powering their home appliances with a home solar system, including John Smith.

John lives in a suburban neighborhood in Austin, Texas and always considered installing a home security camera system that would be powered by solar energy, because this can help reduce energy bills and make sure his camera can function even during power outages.

After conducting thorough research, he decided to install a solar panel and battery backup system.

Step 1: Determine the power requirement

First, John determined the power requirements of his camera. He found that his camera required 12V DC and had a power consumption of 6W. To calculate the current required, he divided the power by the voltage: 6/12 = 0.5A.

Step 2: Choose a battery

John needed to choose a battery that would store enough power to run his camera all the time. He decided to use a deep-cycle battery that can be charged and discharged repeatedly.

He found that his camera had a power consumption of 6 watts and expected it to run for 24 hours. To calculate the total energy required, he multiplied the power by the time: 6 x 24 = 144 Wh

Next, John needed to convert the watt-hours(Wh) to amp-hours(Ah), which is the unit used to measure battery capacity. To do this, he divided the watt-hours by the battery voltage (12V DC): 144/12 = 12 Ah.

So, John knew that his camera would consume 12Ah of energy a day. He chose a deep cycle battery with a voltage rating of 12V DC and a capacity of 100 Ah to make his camera work for a long time.

Step 3: Select a solar panel

To adequately charge the battery, John had to use a solar panel with equal or greater voltage output, which was at least 12V.

John chose a 70W solar panel based on the power requirements of his camera and the amount of sunlight available in his location.

To ensure the solar panel has enough output, he checked the average daily sunlight hours in his location and found that he could expect approximately 5 hours of peak sunlight per day. To calculate the daily energy output, he multiplied the wattage of the solar panel by the peak sunlight hours: 70 watts x 5 hours = 350 Wh.

Since John knew that his camera required 144Wh per day, he thought the 70W solar panel was quite enough after considering various losses associated with the system.

To connect the solar panel to the battery, John used a solar charge controller that was designed to regulate the flow of power from the solar panel to the battery.

After installing the system, John tested it to make sure that the solar panel was generating enough power to charge the battery and power his camera. And things went on well. Now John was ensured his camera would always monitor his property regardless of power outages.

Bonus Tips: For those who are using PoE cameras, it’s necessary to add a PoE injector or PoE switch to the system for network connection. Besides, if it’s hard to build a solar system for home security cameras, choosing a battery-powered camera can also be a great choice for non-stop surveillance.
