Influence of Azimuth and Tilt on Yield of PV System Updated On Wed, Nov 30th, 2022 by Saurenergy Background The tilt and azimuth of a solar panel have a great influence on the energy yield of the overall system. The same panel, at the same installation site, can have different azimuth or tilt. This is a topic we are often asked about so in this Solis seminar, we explore the subject further. About […] Read more
Battery Capacity Selection Criteria for Solar PV Energy Storage Systems Updated On Wed, Jul 20th, 2022 by Saurenergy Background In a solar PV energy storage system, battery capacity calculation can be a complex process and should be completed accurately. In addition to the loads (annual energy consumption), many other factors need to be considered such as: battery charge and discharge capacity, the maximum power of the inverter, the distribution time of the loads, […] Read more
Solis Seminar On The Importance of Using Photovoltaic Cables in Photovoltaic Systems Updated On Tue, Jun 28th, 2022 by Saurenergy Background In some photovoltaic power plant projects, ordinary cables have been used in replacement of dedicated photovoltaic cables, which can provide lower installation costs. This approach puts the entire solar PV system at risk and is dangerous. In this Solis seminar we introduce the differences between photovoltaic cables and ordinary cables, and the importance of […] Read more
How to Quickly and Effectively Determine “ground fault” Updated On Mon, Feb 14th, 2022 by Saurenergy Background In PV systems, ground faults are a relatively common type of fault, but the damage to the inverter equipment is also more serious. Therefore, it is necessary to eliminate the fault in time to restore the system to operational state. This Solis seminar will share with you the causes and troubleshooting methods of PV […] Read more
The Influence Of Winter On Solar PV Systems And Related O&M Considerations Updated On Mon, Dec 20th, 2021 by Saurenergy Background Winter is well and truly on its way for the northern hemisphere with temperatures beginning to fall and already reaching freezing point in some regions. According to forecasts there will be prolonged periods of icy and snowy weather in Europe on its way. So, what are the specific effects of winter on the operation […] Read more
As La Nina Forms, Backup Power Might Rule This Winter Updated On Tue, Dec 14th, 2021 by Saurenergy 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 […] Read more
Choosing the Correct Inverter for High Power M10 (182mm), G12 (210mm) PV Modules Updated On Thu, Nov 11th, 2021 by Saurenergy 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 […] Read more
What To Do When Your Inverter Gives “G-PHASE” Alarm Updated On Fri, Oct 29th, 2021 by Saurenergy Background In PV systems, there can be errors caused by problems on the grid side. As an important operating function of a solar PV system and the grid, inverters are very sensitive to grid problems and will respond quickly. Among them, grid imbalance faults, although rare, can easily affect inverters, PV systems and sometimes even […] Read more
Correct Use of Aluminum Core Cables in PV Systems Updated On Mon, Oct 4th, 2021 by Saurenergy 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 […] Read more
