As La Nina Forms, Backup Power Might Rule This Winter

Background As the ocean and atmosphere of the tropical Pacific indicate, La Niña has already occurred. And the probability of La Niña this winter is 87%. From historical data, in the winter when most La Niña events reach their peak, climate anomalies caused by La Niña include the  probability of colder winters rising. While one […]

Optimising Solar PV Power Supply Systems Alongside Oil Generators

Background In some areas of the world, the power grid can fail or shut down due to unstable supply or planned shutdowns via programs such as “load shedding” and can last an unknown amount of time. During this time, a standard grid connected solar PV system will also shut down. How can we ensure that […]

Choosing the Correct Inverter for High Power M10 (182mm), G12 (210mm) PV Modules

Background Over the past few decades, mainly due to advances in technology and reduction in cost, the size of silicon wafers used in solar modules has evolved from an early stage 125mm to the current standard M6 (166mm), M10 (182mm) and G12 (210mm). What impact do these larger modules have on related equipment? What should […]

Correct Use of Aluminum Core Cables in PV Systems

Grid transmission cables are usually aluminum core. Therefore, in the construction of PV plant projects in residential and commercial areas (especially household PV plant), many users will use aluminum core cables to directly interface with inverter output ports or circuit breakers ports. This can cause many safety problems. This Solis seminar will share the correct […]
