For cheaper solar photovoltaic systems
It is known for several decades, photovoltaic devices that exploit the sun's energy to convert into electricity used to provide a sustainable alternative - and potentially unlimited - the use of fossil fuels. So why these solar technologies have they not been adopted more widely? Simply “because they are too expensive," said Ji-Seon Kim, professor of Solid Physics at Imperial College of ...

Technical Note: Loss-of-load probability of stand-alone solar photovoltaic system
In this technical note, a general method has been given to determine the loss-of-load probability (LOLP) of a stand-alone photovoltaic system as a function of normalised PV array output and energy availability at battery. The energy availability at the battery has been determined by using the solar radiation utilisability concept. To determine the LOLP, the PV array output is required, which is a ...

Market penetration and pay-back period analysis of a solar photovoltaic system under Indian conditions
The use of pay-back period analysis for economic evaluation of solar photovoltaic (PV) system reinforces the importance of the duration of the system. In a dynamic economic environment, the cost of energy increases at a faster rate than the common inflation rate. A time can be ascertained at which the market entry of the PV system will be profitable, i.e. at which the pay-back time drops below a ...

The bottom line on renewable electricity standards
What is a Renewable Electricity Standard (RES)? A RES requires that a minimum percentage or amount of electric power generation come from eligible renewable energy sources by a specified date. Retail electric power suppliers (also known as load-serving entities) must purchase power directly from renewable electricity generators, or in some cases, are allowed to purchase renewable energy credits ...

India’s Potential in Harnessing the Alternate Energy Sources
Long queues for gasoline, high prices and shortage of gasoline are the signs which show that how natural resources are on the verge of depletion. This shows that it is high time for us to view how to utilize natural resources. India is mainly depended on import of petroleum products for its energy requirements. It meets its requirements by importing 70% of petroleum products. This is a point of ...
