Solar lamps have become more expensive in the past decade, and more and more companies and people are looking for a sustainable / green alternative energy source. Compared to rooftop solar panels in grid-tied systems, solar lights are clearly a more affordable “off-grid†solution. In general, solar lights have many advantages, such as no power plug and simple installation, but are solar lights good enough to replace existing electric lights? Read to find out!
Here are some key points about solar lighting:
advantage:
Solar lights are a more environmentally friendly option because they do not use electricity, so they do not require standard electricity.
Solar lights are easy to install and move to the desired location because all wires are on the same pole.
Solar lamps provide soft light, because the power supply is limited, and the working efficiency of the light-emitting diodes at 12 volts DC power is higher than that of AC power.
Bursaries and tax incentives continue to help reduce solar costs
Each solar lamp operates independently of the next solar lamp (except for certain applications, such as signs, billboards, etc.)
The low voltage provided by the solar panel is as safe as AC lighting.
LEDs with directional lighting provide more light where needed and less light where they are not needed. The fixture style is common to many different applications and architecture requirements.
Disadvantages:
The color of sunlight may be too blue, and with some types of light-emitting diodes, this is not a complementary landscape; however, understanding CRI will ensure that you will not get too blue light
Some cheaper units may be fragile and unsustainable, as long as it is a commercially designed system, do research, and then purchase.
There is no solar energy at night, so a large battery pack is needed to operate the electric light, making sure you have the correct power supply. Autonomy for your region
Depending on the geographic location, the size of the solar panel varies depending on the solar radiation available in winter.
External solar lighting
A good key external solar lighting system is the minimum power or Watts needed to get the most light-or lumen-. This is tricky because some lamp lighting is used as a thermal by-product and uses a large amount of electricity (relatively speaking) to produce the amount of light, typical of metal halide and sodium lamps. Remember that light is not always better, and higher watts are not necessarily better than lower watts. The lighting layout completed by the lighting engineer is the best way to ensure that any lamp installed can meet the lighting requirements.
