Solar LED Lighting and Power Systems Future After 2020
The last year has been a difficult one for people all over the world. With Covid-19 spreading to every corner of our world, killing people, businesses, and industries, many people have been affected by the pandemic on so many levels.
Here at SEPCO, we have been lucky to stay going and operational at full capacity through most of the last year with no downtime. Even the small hiccups felt through supply chains were able to get ironed out quickly, so our customers were not affected in ways many in other sectors were. It has been a lucky year for us in solar lighting.
What does this year, 2021, look like at this point? Probably a lot of the same as last year. With the rollout of the vaccine worldwide, a new normal emerging of people working at home and more cities and municipalities upgrading their infrastructures, the decrease of global pollution and CO2 emissions, there are a lot of positive changes still happening.
The solar industry, along with other renewable energy industries, have seen a boom in growth in 2020 and I think we will see this continue in 2021 and beyond. Solar LED lighting and remote off-grid power systems will also be involved in this boom and we will be working at capacity to evolve with this growth and make changes that help propel us farther forward.
SEPCO specifically will continue its work with companies across the US and around the world to ensure they have the systems they need and work with new projects to design solar lighting and power systems to meet their goals. Our solutions have been evolving as design parameters change with the increase efficacy of LEDs, the change in solar panels and the evolution of battery designs. I think you can look forward to some great announcements in the next couple months.
Factors Affecting the Lighting Time of Solar Street Lights
The energy supply and storage of solar street lamps are completed by batteries (lithium batteries). Now the technology of batteries (lithium batteries) has a certain life span. The batteries of solar street lights commonly used currently include colloidal lead acid batteries and lithium batteries. And the span life of colloidal lead acid battery is generally 3-5 years while the one of the lithium battery is generally 2-3 years. If the use of solar street lights exceeds this period, you need to consider replacing the battery.
u Climatic conditions
Generally speaking, the accumulation time of sunshine in the north (the number of sunshine hours in a year) is longer. There are more precipitation and cloudy days in the south, so the sunshine time is less, which directly affects the effect of lighting. Solar street lights absorb much less energy than sunny days on rainy days. If the number of consecutive rainy days in the local area is longer, we must make a good calculation when choosing the configuration of solar street lights to ensure that the solar street lights are able to light normally when cloudy and rainy days.
u PV panel cleaning
The main function of solar Photovoltaic panels is to convert light into electrical energy. Solar panels are easy to accumulate dust if they are exposed to the outside for a long time, especially in places with a lot of sand and dust. Excessive dust accumulation leads to a decline in conversion efficiency, and also causes that the charging amount is lower than the discharging amount and shorten lighting time. In this case, you need to clean the Photovoltaic panel and charge it for two days to restore the original lighting time.
