Current Rating of XLPE & PVC Insulated 1100 Volts grade Underground Cables

The XLPE (Cross Linked Poly Ethylene ) insulated heavy duty cables were introduced worldwide in mid sixties. These cables have overcome the limitations of PVC Insulated Cables such as thermal degradation, poor moisture resistant and thermoplastic in nature. What is current carrying capacity of a cable? The current rating of any cable is defined as the maximum current carrying capacity of the power cable under normal operating conditions of temperature,...

MNRE issues clarification in respect of domestically manufactured solar PV cells

In a major decision that is likely to give further boost to domestic manufacturing of solar cells in India, MNRE has issued a clarification in respect of domestically manufactured solar PV cells. It may be noted that a number of flagship programmes of MNRE such as KUSUM, have provisions for mandatory use of domestically manufactured solar PV cells. However it was seen that some manufacturers have been importing semi –processed solar PV cells (generally called blue wafer) and...

Operations & Maintenance (O&M) For Utility Scale PV Solar Plants

Once the PV solar plant has been built, it needs to be efficiently operated and carefully maintained. Compared to other power generating technologies, solar PV power plants have low maintenance and servicing requirements. However, as International Financial Corporation warns, “proper maintenance of a PV plant is essential to maximise both energy yield and the plant’s useful life. Optimal operations must strike a balance between maximising production and minimising cost”. Indeed, while solar...

Apple inc to enter Photovoltaic Energy producing and Selling business

Selling photovoltaic energy is not the exclusive right of government in USA. Last year the U.S. Federal Energy Regulatory Commission (FERC) has granted Apple the permission to sell energy like photovoltaic energy, power generation and ancillary services to the market. This permission has given the technology giant a new role of Independent Power Producer (IPP). According to Wikipedia, IPP is An independent power producer (IPP) is an entity, which is...

Solar Inverters – Things to know before buying

What is a Solar Inverter? Solar photo voltaic systems needs several components other than the PV panels and Inverters or the machine that converts DC electricity to AC electricity are the second most important part of PV systems. Unless you are having DC appliances to run, you certainly need inverters to chnage the raw DC(Direct current) power generated by the solar panels to AC(Alternating currents) power that is mostly used...
