In the mountainous and hilltop area of Kulambogan, Sibagat ADS, the Philippines, frequent power interruptions from the grid is common and normal to the residents there. To provide a more reliable study environment for the children, this school commissioned JMJ SOLAR to install two solar systems on top of this two-unit school building with two Growatt off-grid inverters, which is of 20kW power output in total. With the sustainable and stable power supply from the solar system, the school can then provide better conditions for the teachers and students.

What is delivery method ?

It is sea transportation to destination port .
When the buyer pay the order,the seller will find nearest port to buyer.and Await confirmation of buyer.
When the sola panel is on board,the seller will send loading bill,commercial invoice and packing list to buyer’s e-mail for customs clearance.

When the solar panel reaches the port ,the buyer have to go to the port ,pay the destination port fee and tariff or duty and pick up the solar panel .
