In 2021,Lebanon met a serious shortage of electricity , the grid power only can provide 2~4 hours power a day , sometimes go cut all day .Not only industry manufacturing ,but also residential,they need power replacement for supporting daily activity.

Gas oil and diesel oil also can help with the situation in short term,however, price of fossil energy also increased a lot , After Russia-Ukraine conflict, the cost of fossil fuels has become higher. In the background , off grid solar power system become a good choice as a private station for Lebanese. Namkoo also gained many project form Lebanon customer , below is the project case photo of a 16.2kw residential off grid solar system with battery.

Lebanon has a mild Mediterranean climate. In coastal areas, winters are generally cool and rainy, while summers are hot and humid. We can see in summer , there is little rainy day at local ,also the sun radiation is most strong during summer.Because of the weather feature , the sunshine resource very rich in summer.

The warm season lasted for 4.1 months, from June 5 to October 9, with daily average high temperatures exceeding 25°C. The hottest month of the year in Bent Jbaïl is August, with an average high temperature of 28°C and an average low temperature of 19°C.

The system uesd 36pcs 450w mono half cut solar panels ,total 16200w , Solar Radiation Average in Jbail : 5.15hrs /day , Based on NASA Data.So average production 58.4kWh /day,1810kWh / months. 32Pieces 12v 150ah gel batteries , can storage 57.6kWh per cycle ,Our battery use GEL type with 3 Years warranty , 7 Years design life ,the technology is from Germany . Now the user is thinking about expand the system ,but there is not enough rooftop space ,our recommendation is a wind and solar hybrid solar system , below is a example of the electrical wiring diagrams.

As you can see in the diagrams , the battery have both the wind power input and the PV input , in this design , the user can choose do not add battery , the battery group can be full charge in shorter time with wind and solar .Of course ,the advantage of wind turbine is when no sun in rainy day , usually the wind power is strong , can ensure the system do not go cut even in night time or in cloudy weather.
