As mentioned above, the size of the solar panel will depend on how powerful the light is and from what material the panel is made of. You will sometimes see that high power outdoor flood lights are equipped not just with one, but with two or more solar panels to be able to produce enough energy to recharge their high capacity batteries. Most of the time, larger solar panels will produce more wattage, because there simply is more surface area on the panel to collect the sun’s energy. For example, lower power lights that produce a few hundred lumens of light can be run by a 1 to 5-watt solar panels, while larger lights will require 10-20 watt solar panels. The more powerful the lighting is, the higher wattage panel will be required to power the lighting. It shows how much power the panel produces in ideal conditions, for example, a 10-watt solar panel will output 10 watt-hours of electricity every hour. One of the most important measurements of a solar panel is wattage. If, however, you are investing in a powerful flood light that will produce thousands of lumens of light, I would suggest getting a light with either a monocrystalline or a polycrystalline solar panel. Because these panels come in a very small size (when compared to ones used to provide electricity for entire buildings), difference in their efficiency practically won’t be noticeable. All in all, if you are buying a lower power solar flood light for less than $100 to illuminate your front door or driveway, you shouldn’t worry much about which type of solar panel is used on the light. You will find these types of solar panels in cheaper, lower power solar lights. Amorphous panels provide the lowest efficiency of 10% and below and are mostly used to charge different low power electronic devices. Both monocrystalline and polycrystalline panels are also used on large solar systems to provide electricity to houses and commercial buildings because of their high cell efficiency and these panels are also used in more powerful solar lights. Polycrystalline panels usually have solar cells in a dark blue color which makes it easy to differ these panels from others. Polycrystalline panels also provide good cell efficiency up to 16% but are cheaper to manufacture. You will see monocrystalline solar panels mostly used in powerful solar flood lights. Monocrystalline panels are considered the most effective, with their cell efficiency (how much solar energy can be collected and converted into electricity) ranging from 15-21%, but they are also the most expensive ones. Basically, there are three types of solar panels used for solar lighting – monocrystalline solar panels, polycrystalline solar panels and amorphous (thin-film) solar panels. Solar panel is one of the key parts of a solar flood light, it collects solar energy, converts it into electricity and stores into a battery to power a flood light. What you need to look for when purchasing solar flood lights? Solar panels Solar lighting product range has grown rapidly in the previous years, and now you can choose from small solar accent lights, motion-activated security lights, and landscape lights, to powerful solutions for large areas such as sports stadiums. Lots of different options to choose from.Using renewable energy not only helps you save some money in the long run but also is good for the environment. Based on the previous point, it is also easy to reinstall solar lighting in another place because the lighting isn’t attached to the grid. Less hassle to reinstall the light in other places.Because solar lighting usually consists of two (lighting fixture and solar panel) or three (lighting fixture, separate motion sensor, solar panel) parts that all are connected with a single cable, installation of these lights is super easy and takes a little time. Solar lights will definitely reduce your electricity bills because you won’t need to pay for electricity to run solar lighting. This one is pretty obvious as solar energy is free for everyone. Solar flood lights run purely on energy collected from the sun using a solar panel, so it can be installed practically anywhere where the sun can reach the panel. More options where to install the lighting.So why should you choose solar flood lights instead of regular, wired outdoor flood lights? But now the situation has changed a lot due to the growing popularity of solar panels and renewable energy and you might find that electronics stores and internet shops even offer more solar flood lights than regular fixtures. Some time ago, the decision was easy – install a wired flood light, as there were very few reliable solar lights on the market. When looking for an outdoor flood light, you might be facing a choice – whether to install a regular, wired flood light or go for the solar option.
