Buying a new product--especially an expensive one--isn&#;t just a simple decision. Smart consumers research the market by looking at positive (and negative) reviews online, consulting friends, reading case studies, and examining the quality and source of the product&#;s components. Understanding the build of a product and educating yourself on the reputation of a brand isn&#;t always an easy task. However, most of this information can be accessed through the web, so the process to educate yourself is easier than it&#;s ever been. But what if I were to ask you about the components and company reputations for commercial solar lights? That isn&#;t as easy as logging onto a review site and checking for a review score, so we&#;ve prepared a guide to help you look for what sells and what stinks when it comes to solar lighting.

Concerns About Solar Lighting: What Makes a Quality Product?

Just like us, you want the best bang for your buck. Here&#;s what to look for when it comes to quality, service, warranty, and other aspects that may be a concern for people switching to solar lighting over traditional.

Solar Panels

One of the most important components for a solar light is--well, you guessed it, the solar panel itself. When you&#;re searching for quality panels on your lights, you&#;ll want to check a few boxes and ensure your panels have these key build factors.

Silicon Makeup

You&#;ll want to purchase a panel build of what&#;s called monocrystalline silicon. The biggest difference between these panels and others is that they&#;re made of a single ingot of 99.9% pure silicon, so the efficiency of the panels is higher than other (commercially available) panels on the market.

Solar Panel Adhesive

Elmer&#;s glue might have a fantastic application for in-house projects, but it has no place in photovoltaic builds. What you need is a heat-activated, electrically-conductive bonding solution. Remember, these are solar panels and they&#;ll be sitting in direct sunlight for years. If you want to ensure your panels will stay functional through constant temperature fluctuations, check that your solar light manufacturer has a great adhesive for the panels. Otherwise, the silicon wafers may lose their effectiveness.

Temperature Coefficient

Another concern about solar lighting that you need to consider is the temperature coefficient for a panel. Some areas that receive a lot of sun hours are also notoriously hot, and so a strong TC would be -0.3% to -0.5 percent. A solar panel with -0.3% means for every degree in Celsius the panel&#;s temperature increases above 25 degrees, the panel&#;s efficiency decreases by .03%. Anything above .5 is a sign of a low-quality panel.

Glass

Glass for a monocrystalline photovoltaic panel needs to be tempered glass. The difference is that it can be anti-reflective and also shatter-proof in the rare but entirely possible situation of something severely damaging the solar light. It&#;s another concern for solar lighting that is commonly looked-over since it&#;s a misconception that any glass will work fine for the panels. The certificates of IEC (IEC, IEC) and UL for your solar panel mean that their glass meets the industry standard.

Light Fixture

Solar energy is important, but if the light fixture on your solar investment doesn&#;t work well--or at all--your light might as well be a wonderful street decoration. Here&#;s what you want and don&#;t want in a light fixture.

LEDs

LED light fixtures are known for being incredibly efficient. These lights are best for solar energy since their luminous efficacy (lumen output per watt consumed) is about 60 lumens per watt. To easily compare, an incandescent bulb is about 15 lumens per watt--not that any proper manufacturer would use an incandescent bulb on an outdoor light (we&#;d hope), but ensure LEDs are used for your solar light to ensure the best lumen output for the power available.

Insufficient Heat Dispersion

Heat is a huge concern for solar lighting. A proper light fixture needs a sufficient heatsink to draw heat away from the bulbs to dissipate into the air. For LED fixtures, the heat is a by-product of the semiconductor within the bulb that produces the light. It&#;s important to check the material and shape of the heatsink to determine if it&#;s sufficient for keeping the junction temperature of the LED bulbs down. Copper is the best material for heat conduction&#;however, it tends to be very expensive so aluminum is used to keep costs down. Ensure the finish and conductive adhesive are quality too so your investment will last a long time.

Low-Quality Adhesives

Check what&#;s holding your fixture together. If the construction components are screws that are easily removed or parts that require a little force to disengage their locking mechanisms, then go in search of a higher-quality fixture. Remember, your biggest concern with your solar light is you want it to last in all sorts of temperatures and weather conditions. Cheap glue and screws to easily remove is a telltale sign of a short-lived investment.

Components

There are plenty of electrical components &#;under the hood&#; of a solar light, and so it&#;s best to check and make sure your investment doesn&#;t use cheap-quality parts. Here are a few components that you&#;ll want to have a high concern with on your solar light.

Controller

These components generally serve two functions&#;they manage the flow of electricity from the battery to the fixture and instruct the light fixture when to turn on and off. A bad controller can shorten the lifespan of your battery or light fixture, so if either (or both) the fixture and battery have problems, be sure to consider that it could be your controller.

A lot of controllers have full light system customization options and are protected with rugged materials so they can survive temperature changes.

Driver

A solar light driver is another major concern for solar lighting. They regulate the flow of electricity to the battery and light fixture. A poor-quality driver won&#;t be able to dissipate heat very well&#;drivers are under frequent electrical load, so if a driver feels like it&#;s made of material that won&#;t last, that&#;s likely the case.

Warranties

As a general rule, the solar lighting company you decide on should provide a range of warranties, either full or limited. Some of the best warranties on the market will provide full coverage for 10 years which covers every component as long as the functionality of the component isn&#;t drained from regular use, improper installation, or damage.

If there aren&#;t a range of warranties, or the warranties last a very short time (only a year for example), there&#;s a large reason for this. Don&#;t buy from that company.

4 Crucial Things to Look at When Buying Solar Flood Lights

When you&#;re in the market for solar flood lights, you need to look at more than just the price. Expensive doesn&#;t mean better, and cheap doesn&#;t automatically equate with poor quality. Solar security lights consist of several parts, including solar panels, sensors, fixtures and casings. When you want to buy solar flood light, look at what the manufacturer uses in its design and what kind of lumens output it generates. 

How to Choose LED Solar Flood Lights

Solar Light Panels Type, Wattage, and Size

A considerable aspect of solar flood lights is the solar panel, as it collects the solar energy, changes it into electricity and stores that energy in the battery. When it becomes dusk, or the sky becomes really dark, it gives the light the power it needs to turn on. There are three things to look for in the solar panels &#; type, wattage and size.

Type

• There are three kinds of solar panels you can use:

• Amorphous solar panels &#; These panels have the lowest efficiency levels, around 10%, and are used mainly to change low-power electronics (cell phones, for example). The panels are found in inexpensive, lower-power solar lights. 
• Monocrystalline solar panels &#; These are the most effective solar panels, with an efficiency range of 15% to 21%. However, they are very costly. Powerful solar lights tend to use monocrystalline solar panels. 
• Polycrystalline solar panels &#; These have a 16% cell efficiency and are less expensive to make. What makes these panels different from other panels is that the solar panels come in a dark blue color. The monocrystalline and polycrystalline panels are installed on commercial buildings and houses where large solar systems are desired. These panels have a high cell efficiency and are seen with powerful solar lights. 

Wattage 

• The wattage is the most important solar panel measurement. It demonstrates the amount of power the panel generates when the conditions are right. For instance, a 10W solar panel will produce 10 watt-hours of electricity each hour. The more powerful the light is, the higher the wattage panel needs to be to produce the light. A 1.5-watt solar panel can generate several hundred light lumens; bigger lights need 10 to 20-watt solar panels. 

Size 

• A solar panel&#;s size is dependent on the amount of power the light has and the panel&#;s material. Monocrystalline solar panels of a thin-film solar panel design generate the same power amount as it does from the smaller panel. Before you buy solar lights, consider the area it&#;ll be installed in and if it&#;ll get enough sunlight. Will there be enough area for the solar panel to be installed if you want a high-power floodlight?

Solar Flood Light Fixture and Casings 

Outdoor floodlights are exposed to the elements &#; wind, rain, snow, ice, etc. Therefore, you must make sure that the lighting is covered in a weatherproof casing. 

Build Materials 

• Casings &#; Casings of floodlights comprise primarily two materials &#; aluminum and plastic. Most high-power floodlights are made with aluminum casings to give the parts inside the best possible protection from the outside elements. Cheaper floodlights use plastic but don&#;t always have the quality protection aluminum does. Manufacturers use durable plastic for their housing to ensure water damage and extreme temperatures. Be sure to do your homework. Even if a manufacturer uses aluminum, it doesn&#;t matter if it will not withstand the elements. 

• IP Ratings &#; An important element to keep in mind when looking at a fixture&#;s durability is its IP rating. The rating shows the amount of protection a fixture has from water and dust. For outdoor solar lights, you want rating protection of IP65.

• Mounting Hardware &#; There are several kinds of solar flood lights, such as pole-mounted lights and ground-mounted lights. See what kind of mount is warranted for your area of installation. Some manufacturers offer an option to buy different kinds of mounting hardware. 

• Cable Length &#; You also want to consider a fixture&#;s cable length &#; the cable that attaches the fixture to the solar security light. You also need to consider the length of the area the lighting will be installed. If a cord is not long enough, you can buy extension cords. However, the longer the cable is, the more it affects the solar floodlights.

Solar Flood Light Brightness and Power 

Lumens and Watts

Lumens measure a fixture&#;s light output and indicate how bright the fixture will be. Watts measures the amount of work the electricity does in a second. For instance, 100W of energy can light 100W for 60 minutes. 

When looking at the brightness of a solar flood light, look more at the lumen rating, not the wattage. Each type of bulb produces different lumens. LEDs are three times more efficient but consume a similar amount of energy that Halogen bulbs produce. 

Special equipment is necessary to get the lamp&#;s right lumen measurement. However, many manufacturers do not use the tool to get their lumen rating, so the ratings they list aren&#;t always accurate. For not-so-reliable brands, this is particularly important. In most cases, this is what you can expect for lumens in certain products:

• Smaller, all-in-one fixture lights &#; 100 lumens
• Motion-activated solar flood lights &#; 300 to 600 lumens
• High-power outdoor solar flood lights &#; 1,000 to 3,000 lumens

The average solar-powered floodlight will have a lumen of 300 to 800.

Color Temperature &#; This relates to the color appearance a lamp produces; or the light of color the lamp generates. This measurement is in Kelvins. Solar security lights should have a kelvin rating of 5,000K to 6,500K.

LED Solar Floodlight Sensors

Sensors play an integral role in solar lighting products because they help in battery conservation and turning on the light when it&#;s time. The two important sensors are motion sensors and photosensors. What do they do?

Motion Sensors 

• As the name implies, the light will turn on when the sensors detect movement around a certain area. There are three typical types of motion detectors &#; active sensors, passive infrared sensors, and combined sensors. The PIR sensor is usually manufactured in the motion-activated solar light and won&#;t pick up random movements such as windblown objects or tree branches.  

Photosensors

• A prudent feature of a solar floodlight is the photosensor (or the dusk-to-dawn sensor). This sensor detects when the light is fading, and dark is imminent, turning the light on automatically when it reaches the set level of darkness. When the morning comes, the light will turn off, saving energy and battery. If a solar floodlight does not have this sensor, you will have to turn on and off the light automatically. When looking for solar flood light with this sensor, you must do your homework and read the description. If the manufacturer claims it&#;s a dusk-to-dawn light, you can feel assured it&#;s got a photosensor.  

Do not buy any solar flood light without a photosensor or motion sensor, as this wastes the energy that&#;s been stored. Manually turning it on and off defeats the goal of solar lighting.
