    Cold vs Warm Climate Regions for Increasing Solar Panel Efficiency

    It is a given that solar panels installed at high elevations perform better than units installed at low elevations, by an estimated 20 percent. This is due to less obstructions and minimized distance for the sun’s rays to travel and reach the panels. But what about cold versus warm climate regions? How does temperature affect solar panel efficiency? Find out below.

    Cold Climates for Increased PV Efficiency

    Scientists tested such factors in a study published in the journal of Environmental Science and Technology. The researchers were able to conclude that exceedingly high temperatures negatively affects solar panel systems. As a result, the unit’s lifespan and performance are severely hindered.

    Interestingly, the group pointed out that heat is a primary destroyer of solar panel components. One of the best ways to minimize exposure is by taking the environment into consideration during installation. Comparing PV systems in deserts and mountainous locations, the latter is exposed to more sunlight, at low temperatures.

    From a cost perspective, solar panels in cold-climate regions may also last longer, due to decreased degradation rates.

    Cost of Distribution

    Installing PV panels in cold, remote locations is not a complete solution to PV efficiency. This is because if the end-user is located far away from the system, costs associated with sending power and transporting materials (during construction) could be overwhelming.

    Ultimately, the recommendation is suitable for usage within the installed location. For instance, Nepal is a frequent consumer of solar energy, due to its mountainous location. The country utilizes solar panels to power airports and infrastructure. Local residents are also fond of using solar cookers at home.

    For increasing PV efficiency in hot-climate regions, the focus should then be keeping the panels cool. Furthermore, this could also be the main reason why large-scale PV systems are setup in lakes, for areas prone to hot temperatures.

  • solar panel mounts

    Types of Solar Panel Mounts

    For solar-powered lighting systems, where or how you install solar panel mounts matters. Some mounting options offer better exposure to natural sunlight, while others actually reduce efficiency by incorporating incorrect tilt angles.

    With this in mind, below are top selections for mounting solar panels.

    Ground Mounting

    As the name suggests, ground mounts hold PV panels close to the ground, in a tilted configuration. There are a handful of advantages to ground-mounted solar panels. First, the units are easily accessible for maintenance and cleaning. Next, the system is less prone to accidental drops from elevated positions.

    However, because the panels are openly accessible, they are more prone to theft and contact with animals in the area. Additionally, ground-mounting is not suitable for locations with limited space or rocky terrain.

    Roof Mounting

    Roof mounting is a very cost-effective and efficient solution for solar-powered systems. This option keeps the panels elevated and away from harmful elements on the ground. Moreover, the units can be mounted flat on the roof, since the surface is already tilted or flat. Roof mounting solar panels may also provide insulation for buildings.

    A drawback with roof-mounted solar panels is accessibility. Operators must use a ladder or roping mechanism to reach the units. This can be extremely dangerous for high locations, during storms and wet weather.

    Pole Mounting

    Lastly, pole mounted solar panels incorporate the best features of roof and ground mounting configurations. The panels (up to 16) are secured on a pole, roughly 4 to 12 feet from the ground. This option is perfect for buildings with limited space on the roof and ground.

    Pole mounting is recommended for locations with several obstructions (such as trees or large ornaments), as a standalone pole can be setup in open sections of the space. Operators can maintain the PV panels without needing to climb a high location.…

  • How Does Cold Weather Affect LED Lights

    How Does Cold Weather Affect LED Lights

    Winter seasons come with extremely low temperatures, with can negatively affect the performance of LED lights. Although the fixtures are more powerful and reliable than traditional lighting options, such as incandescent and fluorescent lamps, it is important to factor in such environmental conditions to prevent premature failure during operation.


    Cold Weather Environments and LEDs


    LEDs are particularly efficient in locations with low temperatures. The units come with components, such as drivers, that can operate as low as 30°C to –40°C. Some specially engineered LED drivers can withstand temperatures down to –55°C.


    By comparison, fluorescent fixtures do not perform well in cold environments. As a result, the units are more suitable for applications in indoor locations. The lights have a performance threshold of roughly 5°C. When exposed to temperatures colder than this range, output becomes degraded.


    For example, exposing a fluorescent light to –10°C environments may result in a 50 percent loss in performance. At –40°C, the lamp would prematurely fail at 10 percent (or less) illumination.


    Protecting Outdoor LED Lights


    Protecting LEDs from cold temperatures require sturdy materials and seals. This is because snow and ice have a tendency to melt on the surfaces of LED lamps. When this occurs, water or moisture can get trapped inside the light, causing internal damage. A breather or proper ventilation can be applied to the enclosure of the fixture to reduce the buildup of moisture.


    In addition to protecting LED work lights, it is equally crucial to ensure the unit’s other components are well accounted for at all times. Wirings and pipes supporting the lamp should also feature some form of weatherproof or waterproof protection, such as a NEMA 4X rating.


    Lastly, as cold temperatures can affect the performance of switches, pushbuttons and lubrication, it is recommended to test LED fixtures periodically for consistent output.…

    LED Lighting Tips for Open Plan Offices in Commercial Buildings

    Open plan layouts have been trending in commercial offices for almost a decade. The configuration utilizes a large, open room with segregated sections for various departments or tasks. Incorporating LED lighting inside businesses with open plan layouts can be complex and tricky, due to numerous considerations that need to be factored in. Such factors include the type of work being conducted in the space, working style of employees and types of activities taking place in the segregated space.

    LED Lights for Detailed Tasks

    Businesses with open plan layouts usually provide plenty of general lighting over the space. It is important to consider that changes to general lighting systems can have profound effects on the entire office, due to its shared nature. With this in mind, most of the focus for optimal office lighting in open plan configurations is illumination for detailed tasks.

    For cubicles, one should install LED lamps or cut-off fixtures that point downwards. This type of light prevents beams from trespassing into surrounding spaces. Pantry and break rooms do not require task lights. For such rooms, it would be possible to include low color-temperature LED luminaries in order to promote rest.

    Spaces Near Windows

    Open plan layouts may involve the installation of large windows for natural lighting during normal business hours. Such spaces do not need extremely bright LED lamps, compared to spaces located in the middle of the open floor area. However, because natural lighting varies greatly, depending on the time of day and weather conditions, it is recommended to use a dimmable lamp with different brightness settings.

    Lastly, offices that use numerous monitors and panels may consider applying indirect lighting systems to reduce glare. Such LED fixtures are pointed away from bright screens and the work space, at the wall or in other directions with minimal ongoing activity.…

    Types of Outdoor LED Wall Pack Lights for Daylight Saving Time

    For offices and commercial buildings, October is the perfect time to setup LED wall pack lights. With Daylight Saving Time ending very soon (November 5), the fixtures can provide extra illumination and security during long periods of darkness.

    There are several models to choose from when selecting an LED wall pack light for your building. Below covers three types with very useful applications for the upcoming winter season.

    LED Wall Pack Lights 101

    An LED wall pack light is a rectangular fixture that provides general illumination around buildings. The outdoor rated units are typically mounted on the wall, with the beam pointing upwards. Previously, metal halide technology was used to power traditional wall pack lamps. These days, LEDs are proving to be better options, allowing operators to toggle the lights, select from a range of color temperatures and benefit from lengthy lifespans (50,000+ hours for LEDs).

    Types of LED Wall Pack Lights

    LED wall pack lights can be equipped with different features, depending on their intended applications. For establishments operating within urban locations, units with cutoff shields or covers should be used. The lighting components ensure the beams are always pointed directly up, contributing to less light spillage.

    You can find different types of wallpack online by visiting Larson Electronics or any other commercial lighting superstore.

    LED wall pack lights with dusk-to-dawn or motion sensors are particularly useful for improving security around low-activity sections of the building. The fixtures automatically turn on when ambient light levels are low (dusk-to-dawn) or when it senses movement (motion sensor). For maximum illumination, this type of wall pack lamp is not cutoff. Instead, the fixture may feature a diffused cover.

    Individuals who want to boost aesthetics around a commercial building can benefit from deploying RGB wall pack lights. The luminaries are capable of producing up to 16 million different color combinations using RGB diodes. Remote controlled features offer hands-free configuration and easily accessible color profile settings.…

    Productive Lighting Options for Cubicles and Small Office Spaces

    Lighting Options for Cubicles

    In the past decade, open floor plan trends for office buildings have reached new heights. Taking on the configuration of a large room with segregated work spaces, cubicles and dividers, the modern arrangement is effective in reducing expenses related to building rentals and maintenance.

    Open floor plans in commercial offices have a dark side that rarely gets attention. The layout can sometimes work against employees, which has been linked to a decrease in productivity due to congestion and distractions. An effective way to curtail this unwanted effect is to boost lighting within specific cubicles or work spaces.

    LED Desk Lamps and Cabinet Lights

    LED desk lamps are a great place to start, for people who have no secondary lighting system in their cubicle. Ideally, the unit should be compact, to promote spaciousness, and always pointed downwards to reduce light trespass outside of the target location. Extendable arms are recommended for cubicles wherein detailed tasks, such as drafting, designing or soldering, are performed.

    For a sleek, low-profile option, try using LED cabinet lights. The luminaries are slim and can be installed under one’s desk, shelves or inside large storage spaces. Due to the small space, a high-powered fixture is not needed.

    What About Overhead Lighting?

    Overhead lighting over cubicles in office buildings with open floor plans could be difficult to implement, due to the shared nature of the space. A permanent fixture hanging over the target location from the ceiling could be distracting for other workers and may violate company policy.

    Alternatively, for individuals who persistently need overhead illumination, a tall, standalone lamp could be an effective lighting option for cubicles. To prevent disturbing nearby employees, a cover should be placed over the light to control the direction of the beams (downward). For decreasing eye strain during long periods of work, a lamp with dimmable features is recommended.…

    How To Install Recessed Lighting Systems In Your Office or Home.

    Install Recessed Lighting

    Recessed lighting systems provide a plethora of benefits for businesses and homes. The compact, space-saving luminaries are very popular and offer very clean configurations and well-focused illumination for detailed tasks and general activities.

    Unlike traditional light bulbs, which take seconds to install on conventional sockets, recessed lamps command a very different method of implementation in the target area. This article provides tips to install recessed lighting in homes and commercial spaces.

    Start with a Plan

    Installing recessed lights in a location that does not have any existing recessed units (hence, no holes in the ceiling) requires one to punch openings in the target area. Such holes will facilitate the recessed configuration that the lighting style is widely known for. To avoid creating extra or unnecessary holes in the ceiling, it is important to first create a plan or drawing for accurate execution.

    For best results, make sure the units are spaced out evenly across the ceiling. Avoid installing the lights in corners. Since furniture can greatly affect lighting configurations, it is also crucial to factor in such components during installation.

    Electrical Safety

    When wiring up your lights, don’t forget to disconnect power from the main circuit box. Assuming you have addressed the power and wiring requirements for the lighting system, the next step is to connect the wires from the ceiling to the junction box. From here, be sure to test the power before inserting a bulb into the fixture. To do this, simply turn the power on and use a measuring device to check the status of the socket.

    After confirming the status of the socket, turn the power back off. At the final stretch of the process, the housing is secured to the ceiling and stray components are trimmed or cleaned for aesthetics. It is recommended to use an LED bulb for recessed lighting systems for energy-efficient performance.

  • indirect lighting

    Benefits of Indirect Lighting Configuration For Businesses

    Office spaces command the use of special lighting configurations to serve the needs of human workers inside the building. Exposure to direct lighting for long periods of time can lead to visual strain, stress and a sharp decrease in productivity. To address such challenges, indirect lighting options should be applied.

    Characteristics of Indirect Lighting

    Indirect lighting offers unique benefits for commercial spaces. This type of configuration is soft and consistent throughout the room, making it ideal for locations that use a lot of computers. Glare is greatly minimized with indirect lighting and workers are less prone to eye strain, when conducting rigorous tasks. Additionally, when workers up look at the light source, they are more likely to look at stray beams or the surface the light beam is bouncing off from. Without light beams shining directly into the eyes and face of employees, a sense of comfort is promoted inside the building.

    When mounting lights for indirect illumination, there should be a gap between the fixture and the target surface. If it’s the ceiling, the units are pointed upwards, with roughly three feet (or more) of space in between. Diagonally positioning the fixtures allows for a wider beam spread, though the quality of light decreases the further the beams travel.

    Fixtures for Indirect Lighting Systems

    Selecting luminaries for indirect lighting is a fairly straightforward process. It is important to remember that the units will be pointed at upper walls or ceilings. Because of this, the fixtures must be extremely bright to allow light to radiate and encompass the entire space. Indirect lighting is ideal for general illumination, since it’s not possible to create highly-focused beams. For such requirements, workers could use desk lamps and spotlights.

    Furthermore, since indirect lighting is noticeably softer than direct lighting configurations, businesses may incorporate large amounts of natural daylight into the building, via large windows, clear roofs, doors and etc. To prevent creating a work space that is too relaxing, high color temperature fixtures can be used for enhanced clarity.…

  • Which High Power Boat Spotlight Is Best

    Which High Power Boat Spotlight Is Best?

    Even though most boaters usually do not use lighting on their boat outside the required navigational and ballast lighting prescribe by Coast Guard regulations, there still remain a few types of high power lighting that can confirm critical in confident situations. Spreader lights are a regular addition to above deck lighting systems and supply the extra brightness needed for things like preparing for dives, night fishing, and just clear casual get together. Spreader lights, nevertheless, are far from being demanding or unduly necessary, so we’ll skip those and head to the lighting almost anyone who owns a boat should also have specifically on board a high power spotlight. click here for more details.

    Boat spotlights never receive a whole lot of attention. Apart from the truth that they see exceptional use, many boaters see them as irrelevant and commonly a mess that is hard to defend establishing in a place of eminence, even though this is where they commonly are at their most efficient  positioning. According to Coast Guard regulation, extended operation of a spotlight is frowned upon and allowed only under certain outlook, and in unusual instances is it allowed while ongoing. The general rule of thumb for boaters running at night is that it is better to run with as few light running on decks as possible as it is better to let your eyes to commonly adjust to dark conditions, and any source of light can intervene with or decrease your natural vision once your eyes have become adapted  to dark. In spite all of this, still, spotlights do actually play apart in making sure your boat is correctly furnished and can be crucial during unexpected conditions or an emergency.

    The most ordinary use for a boat spotlight includes navigating new channels or waters. Even though a lot of markers are bright or appropriate with obvious surfaces to make recognizing them at night simpler, almost as many have no such additions. To make matters worse, many markers even though outfitted with search lights beacons or lights, commonly go months without being serviced, so burnt out marker lighting is a common occurrence. When operating an different waterway or channel, it makes sense to use a spotlight casually as a way to brighten potential restrictions and recognize markers. As long as you are not using the light as a headlight and use it only long enough to get posturing and recognize positioning, most regulations allow such use. In other, more detracting situations, such as when encountering another vessel in harsh distress at night or man overboard, there are few who would find mistakes with the movement of a high powered spotlight and in any of these cases such a light could make the difference between a tragedy and a happy ending. for more details, visit :

    Which High Power Boat Spotlight Is Best

    Not too long ago, most spotlights were either a plain halogen lamp or high force discharge design. They could be either handheld or a full on remote controlled unit forever mounted to the highest of a bridge or the external limits of the bow. Even though efficient, halogen and HID spotlights have some important limitations which can straightly decrease their capabilities. With halogen spotlights, the basic factor’s affecting their accomplishment has always been the kind of the light beam they produce and almost short generation of the halogen bulb. Most halogen boat spotlights average about 50 watts in power, and produce a somewhat yellowish light beam that even though relatively powerful, is often only poorly concentrated and includes lens artifacts. This can be seen in the conventional boat spotlight when exchanged on and shimmer against a big flat surface as dark spots inside the center of the beam and a lot of “spillage” external of the main beam body. Such effects symbolize poor visibility and decrease intensity, resulting in a shorter reach and less than optimum contrasting and detail reading. Finally, halogen spotlights can run quite hot and pose burn danger, and the short 500-hour average life span makes them less than trustworthy.

    HID boat spotlights symbolize an important  step up from halogens, and provide important developments in beam longevity and quality. Most HID boat spotlights are of the 35-watt variety, and can produce light beams reaching up to 5,000 feet in length. Because of their bulb design they produce a light that is far more severe and whiter than halogens, helping to develop beam effectiveness and efficiency. Like halogens, however, HID bulbs run quite hot. HID spotlights also commonly require 30 or more seconds to warm up and reach full product levels as well. Lamp life is much longer which HID spotlights, but their glass design and high running temperatures can result in problems with lamp breakdown due to disclosure to wet conditions and rough handling, both of which are certainly usual on board a boat.

    LED spotlights are a modern arrival on the spotlight scene, and they propose a far more efficient alternative to both halogen and HID spotlights. LEDs give much higher light and beam quality than halogen lamps, and can produce a certainly described  light beam with few spillage and no beam artifacts. The color kind of the light produced by LEDs is especially best as well, with a much whiter presence and far best detail and color interpretation being the more important  improvements over halogens.
