In the early days, solar energy was seen as something of a novelty that couldn’t possibly compete with nuclear or oil powered energy. But it has managed to stay the course and today it is becoming seen as a realistic, viable option as an energy source for the future.
But even though solar technology has come on leaps and bounds since the humble hand-held calculator, there still remains a lack of comprehensive understanding of how it actually works.
This short article will elaborate on some of the fundamentals of solar energy and how it can become the answer to carbon reduction, cost-efficiency, and community empowerment - and also, how your home security system can benefit from it.
"The sun is the largest source of nuclear energy in our galaxy," writes Stephanie Drew, an author at Researchpapersuk and LastMinuteWriting. "Every hour it sends enough light particles", - (known as photons), - "to potentially satisfy global energy needs for an entire year!"
We capture the energy of these photons when they knock the electrons free from the atoms contained within the solar cells which make up a solar panel. These electrons are generated into electrical energy, specifically Direct Current (DC). Using solar energy can get you off the grid and make your home safer in case of emergencies. Your home security system will not rely on regular electricity to work and you’ll also spend less money on electricity bills.
One of the issues that solar energy has faced has been the fact that most power grids work off of Alternating Current (AC). The reasons for this are manifold and have a long history, but primarily it has been traditionally less expensive to use than DC and has the benefit of being able to travel long distances in a relatively short window of time. This has meant that solar energy developers have had a hard job trying to get it applied practically.
For a long time, solar energy was converted from DC to AC via inverters. Solar arrays, the fields of multiple solar panels worked off of one inverter to convert the current. The issue with this was that if the inverter went down, it meant the whole array was rendered useless. In addition, the circuits were often in series, which also meant that if a solar panel went down, a similar thing happened.
But in the past decade, solar power developers have created Micro-inverters. These are smaller inverters designed to work with one solar panel at a time, localizing the power source and avoiding large scale power outages.
So revolutionary has this technology become that we are now seeing solar energy systems designed specifically for the home. This means essentially a more affordable approach to home energy.
As a result, governments and local authorities across the world have sought to incentivize a large scale adoption of home solar power. One of the ways in which energy companies have done this is to recognize that solar energy is generated in daylight hours. This means, for most people who work during the day, that there is often excess power created from home energy systems.
For those using solar panels, this excess of power is fed back into the grid for use elsewhere. Customers get this back in the form of credit which can then be used to draw back from conventional grids during night time. This is a great thing because you can rest assured that your home security system will work at all times, and you are also saving a ton of money.
"Solar panels are incredibly durable," says Claire Redmond, a regular contributor to Draftbeyond and Writinity. "Most manufacturers will offer a 25-30 year guarantee, but in some instances, solar panels have been known to last even longer with very little effect on their productivity. There is also minimal maintenance required other than clearing of snow or debris."
This means that you will save up a lot of money on bills and you are also investing in something more durable. Your home security system will be powered by something strong and long-lasting.
Impact by Weather
One of the big questions people ask about solar energy is: ‘What happens on cloudy days?’ Of course, direct sunlight is the ideal to generate energy. But it is important to remember that solar energy is generated by light rather than heat. So, in short, if it’s light out, then solar energy can be generated. This means that you can rely on solar energy being there to power your home security.
