Solar panels are made up of solar cells which are diodes or silicon junctions or check valves that put out 0.5 to 0.6 volts each without load (open circuit). To charge a 12 volt battery, you put 10 solar cells in series to get roughly 20 volts which under load will drop down to closer to 15 volts.
Every solar cell is a diode and not only prevents the backwards flow of current it also prohibits forward flow of current without sunlight to excite the electrons and bridge the junctions.
As solar panels are strings diodes wired in series, if you partially block one diode by providing less light due to a shadow the performance of the entire panel suffers disproportionately. Itโs actually bad for the panel to be exposed to shadows continously as when you are blocking flow of current due to shadows you are starting to wear down the silicon junctions in other cells eventually causing permanent damage to the panel.
That was my reaction upon reading on Fox News that Vance Luther Boelter, the accused man who heads the Praetorian Guard Security Services, a private security consulting group. The thing is the private sector and public sector security services are very inter-related, often with retired and even active duty police officers moonlighting in the private sector protection and loss-prevention sector.
The truth is that most police officers, outside of wealthy cities and states are pretty poorly paid. In wealthier areas, itโs true cops can make good money especially with overtime. But most police officers have fairly meager salaries, and many are actually quite poorly educated for all the power they have and the position of authority they hold, enforcing laws. Itโs actually remarkable that a person who can arrest and detain a person over a technically-complex thing as the law, which spans millions of pages, in many cases is not required to have anything more then a high school diploma, and potentially an associates degree in criminal justice or a brief training course.
So itโs only logical for police officers to seek work in the private sector to make more money. And there is no requirements at all to work in the private sector protection and lost prevention sector, though many states have requirements for concealed carry of firearms and private investigations. Instead, people in the private security sector usually rely on other credentials to show their merits while marketing their services, such as police officer services, classes taken, experiences earned. But often the lines are blurred.
And because those lines are so blurry, private security consultants often have many of the same things are bonafide law enforcement officers. Many drive the same model automobiles are police do, indeed one of the local private investigators down the street is outfitted with a black Dodge Charger with steel wheels. Probably the persuit package, could even be a retired cop car, he either bought off the force he worked for or is currently employed by. He might even have a blue or black dress shirt and wear a badge. And heโs probably far better paid to many of the local cops, especially in small towns.
Many private sector security officers not only are cops retired or active, many also have very close relationships with politicians and actual serving policeman โ scurrying favor by offering free security services at events โ and personal defense and awareness training. Many enjoy cultivating their relationship at the local watering hole and elsewise. When you are in the private sector, and donโt have a public job, you can be a lot more loose with others. Many shoot at same ranges and hang out with real cops, theyโre drinking buddies. And many meet at court and work together closely on law enforcement activities, such as prosecuting those accused of shoplifting and other crimes against businesses.
The truth is real cops probably should be closer to lawyers in their education, rather then tough men. District Attorneys have to be lawyers in most states, and certainly all higher-level judges and appeals judges are, though town justices often arenโt. The fact that police are so badly paid and often uneducated is a real problem and it only makes them more prone to getting caught up in ideological movements like the the III-percenters, who advocate using official positions to spark a political revolution. This is problematic on so many levels, when government enforcement officers โ โ the police โ should be non-political and neutral enforcers of the law as written. Itโs really messy.
Police should be paid more with a higher base salary, and work far less over time. At the same time, they should be much more strictly limited at what kind of outside income they can take and who they fratnize with. However, the private and public sector security and policing industries are closely linked, and both certainly have common interests and bonds that often are tightly linked.
