These systems are still expensive compared to the conventional electric generating plants such as hydro. And since they only generate power during the day, batteries or other storage systems are required to ensure power availability during the night or times when the conversion is low. This means spending more on batteries, which are currently the most popular storage devices.

Another limitation is the intermittent nature of light, making the energy unsuitable for some applications.

Space limitations may influence the maximum power that a consumer can generate. The cheaper panels have a lower conversion rate and require larger areas. However, customers may overcome this by using the more expensive but higher efficiency panels which require less space.

Improved photovoltaic technology, mass production and lower installation costs have seen the cost of photovoltaic systems and components such as batteries fall rapidly. Incentives such as financing, rebates, and wide acceptance by homeowners have influenced the use of the photovoltaic cells.

Frances Ellen Watkins Harper (1825-1911). Her bio is beyond the scope of this entry, but I encourage you to follow the link and check her out. Get a little perspective on life today by reading a paragraph about this amazing human being and poet.

Harper’s poem, “Let the Light Enter,” depicts light in an interesting and fresh way, fresh still, even 100 years after her death. Poetry, generally speaking, is like a vast collection of opportunities to learn about yourself and the world in which you live. I invite you to take a minute to read “Let the Light Enter.”

The Dying Words of Goethe

He just urgently wants to watch the “balmy sunshine/ Play around” his deathbed. He just wants to experience the sensation of light doing it’s thing. “More light!” he demands. It strongly suggests that appreciating and enjoying the beauty of light is what Goethe, a lifelong thinker and poet who lived from 1749 to 1832, finds most worthy of his final precious minutes. That’s a big deal. In choosing between the pleasure of thoughts and the pleasure of the material world, he chooses the latter. It’s like all the things that seem to separate us from the natural world are shown to be false in the final moments. Think of a dog lying on a rock in the sun. Maybe that’s the purest state of being, just lying there, not thinking much, and enjoying the pleasure of the light, the sound of a brook. And maybe that’s why Goethe wants to pass away in such a state.

Knowing when to install a new circuit in your home or business may seem like a daunting task. After all, you’re no electrician, and figuring out the details seems stressful! To which we at Kolb say, “No Problem!” There are specific cases and situations where installing a new circuit is really necessary, and all said it’s pretty clear when you need one. That is, if you know what you’re looking for.

We’ll skip the science lesson and spare you the details of Ohm’s Law (though it’s fairly interesting reading), and other laws that apply to circuits. What you need to know is that a circuit is a dedicated device that houses electricity reserved for a specific task. Like a circuit for running your fridge, or to plug in your dryer.

A circuit operates in a loop, delivering electricity to the object in need of power, and then returning the electricity to the source (your electrical panel) when on or off. So, why would you need a new circuit? There are two primary cases:

If your circuit is not operating properly, it’s obviously time to seek a replacement. Not doing so can create some serious issues, the least of which is your appliances not running. A busted circuit can present serious dangers to your home, and should be addressed immediately. You can spot one by:

The other common time to get a new circuit installed is when you plan to add new, improved or newly existing appliances to your home. Many common use electrical machines require a lot of power, and plugging them into an existing circuit shared with other items will likely result in breaker flips.

Why? because a circuit is designed to supply a very specific amount of power, via your breaker. If you exceed the limit the breaker places on your circuit, the breaker will flip and refuse to allow the supply. This is why refrigerators, air conditioning, washing and drying machines and microwaves are often given a dedicated circuit.

A beautiful deck is something that should be enjoyed long after the sun goes down—which is why it’s important to have the right kind of deck lighting! From a purely functional point of view, deck lighting serves three purposes:

But when it comes to the right type of lighting for your home, deck lighting can do so much more! The key is to design a lighting system that performs all three of the above tasks while enhancing the look and feel of your deck. Rather than flooding the deck with simulated sunlight, integrate accent lighting with posts, railings, stair risers, and other elements to create an inviting after-dark atmosphere.

Low-voltage deck lights – the most common types of deck lights, low-voltage lights are a safer alternative to line-voltage, posing almost no risk of electric shock. Electrical connections with low voltage lights are simpler, requiring neither a permit nor a license to install.

Disadvantages of low-voltage deck lights are that they require a transformer, and unless they are divided into more than one run of wiring, they share the same 12V of power—which, if you have a lot of lights, can reduce the brightness.

Line-voltage deck lights – line voltage deck lights are brighter, but their installation is more strictly enforced. All connections must be made in an approved electrical box, and any cables run in the open must be enclosed in a proper conduit. Line-voltage deck lighting must be installed by a licensed electrician.

Solar-powered deck lights – because solar deck lights require no electrical connections, timers, or switches, you won’t need to drill routing holes, run wires, or make connections to install them. What you will need, of course, is steady sunshine—usually six hours per day, according to manufacturers. Sunlight charges the lights’ batteries, which mean they are typically limited to post-cap features, although lanterns, string lights, and recessed solar lights are available.

The solar batteries will need to be replaced every 500 charges or so, but fortunately doing so is fairly easy.

Once you’ve decided which type of deck lighting you want, it’s time to choose how you want that lighting installed. An ideal deck lighting design makes use of all three styles of lights: post-cap, side-mount, and recessed lights.

The largest and most prominent fixtures in the accent deck lighting category, post-cap lights sit at the top of your deck posts, usually at the top and bottom of staircases and at intermediate posts along the perimeter of the deck. Post-cap lights are available in a variety of colors and styles to match your deck, and most manufacturers make dummy post-caps, which are unlit and allow for some space between light sources.

Side-mount deck lights can be installed on the side of posts instead of the top. Side-mount lights can be beneficial if your posts come to eye level when guests are sitting down, as post-cap lights could shine light directly into peoples’ eyes.

Recessed deck lights are the perfect example of how to accent a deck without overlighting it. Recessed deck lights are installed in holes drilled in the stairs or the floor of your deck to provide lighting while being almost perfectly hidden during the day.

Incandescent Deck Lighting – incandescent bulbs are widely available in several different shapes and wattages, and because they are relatively inexpensive, replacement is quick and easy. They cast a softer, warmer glow than LEDs, but consume more energy, making them less efficient and shortening their lives.

LED Deck Lighting – because of the complex housing and circuitry involved, LED lights tend to be more expensive than incandescent lights. They tend to be more than worth the cost however, with vastly improved lifespans (10,000 to 100,000 hours) and high efficiency with almost no heat production. The trade-off is that unless mirrors or reflective surfaces are used, the light output is focused narrowly in only one direction and can be harsh on the eyes in contrast with a dark backyard.

The right type of lighting can make all the difference for your deck. For outdoor lighting installation in Maryland, Virginia, or Washington, DC, call Kolb Electric today!
