Solar Farm

From science fiction to massive solar plants in the American West, solar energy has fascinated and tantalized scientists and writers for generations.  The promise of easily-accessible, virtually free energy from the large fusion reactor at the center of our solar system (the sun) is enticing and we’re getting closer to harnessing its power effectively every day.

Solar power is interesting because it’s one of the few electrical energy systems that does not use a turbine to generate energy.  Photoelectric cells contain a material that releases electrons when hit by a photon, generating electrical power.  There are no moving parts, no fuel to burn and pay for, and only occasional maintenance to keep the system performing optimally.

So what is holding back the proliferation of solar energy?  Space and storage.  We can generate large quantities of energy from solar, but we do not, at present, have the right method to store that energy for periods without sunlight (night time and storms).  So far the best response has been homeowners installing solar cells on their own homes with battery storage systems linked into their own neighborhoods.  By splitting up generation and storage within the neighborhood itself, enough solar cells can be installed to generate energy both day and night.

Space is at a premium when it comes to energy generation.  Solar power plants take up more space than traditional plants, while generating less energy per square foot.  Because solar cells need to be placed over large areas to maximize sunlight, installing power plants in urban areas can be difficult.  Though installing solar cells on your home can be done simply.

We mentioned self-starting or “œblack-start” energy systems.  These systems can be started without power applied to the system, a huge benefit to fuel-fed power plants, and necessary in the event of major blackouts and power losses.  True, we can supplement with gas turbines or nearby power generation, but we also want black-start renewables.  Fortunately, hydroelectric power plants require no off-system power to function.

Hydroelectric plants are special because, while they also have a somewhat variable energy source, they also have one of the best energy storage systems available: potential energy.  Hydroelectric dams use flowing water to spin turbines, typically generated from lakes and rivers.  Rather than storing generated electricity, hydroelectric plants can store water at a higher altitude.  By storing water in special tanks, they have access to electrical generation potential by simply releasing the stored water and allowing it to spin the turbine.  Hydroelectric power is perfect for energy storage, but they’re limited to specific areas.

5-pin SPDT (single pole, double throw) automotive relay.

Relays are essentially two parts in one package. The first part is an inductive coil (pins 85 and 86). This coil is the “trigger” function of the relay. By applying both a positive (+) and ground (-) to the contacts, current passes through the coil. When current passes through the coil, a magnetic field is generated and moves the switch (the arrow in the diagram). This is where the second part of the relay comes into play.

The second part of the relay is the “switch.” The switch has three interface contacts—common, normally closed, and normally open. “Normally” refers to the state of the relay not being energized.

While relays can be used for virtually any task, there are some very useful, simple applications for adding LED lighting to a vehicle. Please note that this wiring only pertains to the relay—not the wires in the vehicle. Before interfacing with a wire in a vehicle, always ensure you test the wire with a digital multimeter first to confirm circuit function.

Positive Switching

Positive switching is used for applications where the “trigger” for your switch or circuit is positive. This could be an ignition, brake, or reverse light wire for example.  This could be used for applications such as off-road light bars, work lights, additional brake lights, and other exterior lighting.

Negative Switching

Negative switching is used for applications where the “trigger” for your switch or circuit is negative. Negative triggers are often found in door, hatch, and trunk triggers as well as many interior switches. This could be used for applications such as footwell lighting, truck bed lighting, under-hood lighting, and other interior lighting.

Switch Activated With Ignition Override

This is useful for applications where you want to turn your light on or off with a switch but only want the light to remain on when the car is running or key is in the “ignition” position. The main advantage to this is—even if the switch is left on—the light (or output circuit) will shut off when the key is turned off so that the battery will not be run down.

When you plug something into an outlet in your home, you probably don’t really take the time to think about where the electricity to power your appliance comes from. You plug it in, it works. But, what do you do when it doesn’t work?

Homeowners are constantly making improvements to their home. This may include upgrading or installing a new air conditioning unit, replacing the old fridge with a newer, more family-friendly model or adding a hot tub to the backyard. If you have already made these investments or are considering making them, you should contact your electrician. Beverly Hills residents can rely on the professionals at The Electric Connection to provide fast, friendly and knowledgeable service.

An electrical inspection will be needed to determine whether or not your existing electrical panel can handle these much larger items. Hot tubs, AC units and larger power tools will need more power than the typical appliance. If you have a newer home, it is a fairly simple process for an electrician to install the outlet needed to power the new item.

Older homes may need an electrical panel upgrade to support the electricity demands. An additional breaker may need to be added. In fact, this is may apply to newer homes as well, depending on the service that was put in during construction of the home.

If you have already hooked up a new refrigerator or stove and notice you seem to be tripping breakers, it is likely you need an upgrade. This is a sign there is too much draw on a breaker or that a breaker is weak. An electrician in Beverly Hills will be able to determine what the problem is during the inspection. If you are ready to take care of those tripping breakers or have more questions about what it takes to get your new appliance properly wired, give The Electric Connection a call.
