Solar Inverters

Solar inverters are based on PV (Photovoltaic) Solar technology. This technology is used to convert sunlight into electricity. This technology is useful mainly because it uses solar energy which is an abundantly available resource. Secondly, it is benign in nature. This is because it does not produce any noise or harmful emissions and does not require water for generating electricity.

Solar Inverter Design Requirements

Solar Inverters comes with simplistic electrical requirements; specific performance requirements; and protection functions. Although there are few thermal requirements that require greater attention like the inverter system and related components cannot attain temperature beyond a specific value to avoid risk of fire, overheating or damage of insulation; temperature of switching devices should be maintained below certain specified value; due to inverters installation outdoors, they should be capable of handling extreme temperature fluctuations like -40 to 50 degree Celsius; and the like.


Major challenges

The major challenges of using these inverters include thermal management; robust performance; attaining a targeted reasonable price in the coming years and attaining an inverter lifetime greater than 15 years.

Future Advancements

Few of the possible future developments are listed below:

  • Development of micro grids to achieve better grid quality and greater reliability
  • Creative innovative topologies to generate more power and better efficiency
  • Developing HALT (Highly Accelerated Life Testing) and HASS (Highly Accelerated Stress Screening) can help improve the quality and reliability of inverters
  • Use of highly improved system components to improve the lifespan of inverters
  • Building the inverters with equal efficiency by using lesser components



Conclusion

From the above discussion, we may conclude that there is a need to make changes in the inverter design to improve the efficiency, reliability and life-span; and reduce the cost. Also, manufacturing and testing side is also required to improve to further upgrade the quality of the inverter. Furthermore, researchers need to develop advanced robust control techniques to upgrade the performance of inverter so as to lower the inverter downtime and to remove costly sensor components.
Nevertheless, solar inverters have a lot to offer to our growing solar power industry and they should be exploited for the same.

Solar Energy- The Energy of the Future

More often than not, solar energy has been touted as the energy with a commendable future. Abundant and clear, this energy has soared with the beginning of the 21st century and is increasingly becoming cost effective. The three primary technologies that are used for their generation- high temperature, low temperature thermal and photovoltaics are now widely available.

The Energy of Future

The environmentally conscious citizens are taking drastic and novel steps for the conservation of solar energy. Each day, more plants are set up, capacity records get broken and ambitious projects are lined up. In this respect, RaysExperts, a company dedicated to the cause of making solar energy available to large sections of the population is doing commendable work. They have generated huge amounts of electricity at 3 destinations- Baap, Gajner and Kolayat. At RaysExperts, the belief that solar energy will swiftly become a dynamic energy source, to meet the needs of energy security and peak demand, is what drives them forward.


What makes the biggies of the industry swear by its credibility is that it is an extremely clean source of energy. The solar panels, which are installed, typically perform for a period of 25 years approximately, are very low on maintenance, generate electricity without emissions or pollution, contributing to minimum global warming.


The current challenge, however, that the industry faces is the period when the growth of solar energy will accelerate as well as the rough patch prior to its widespread and extensive adoption which would eventually drive explosive growth. However, with the assistance of a highly talented and dedicated team of professionals, RaysExperts is close to overcoming these challenges by developing solar plants over an area of 400 acres.

Evolution of Solar Energy



One categorization that needs to be made here is that solar energy can be both active and passive. This depends on the mode of capture as well as the way it is utilized.

-          Active solar energy-

Use of mechanical or heating equipment for the conversion of solar energy into heat energy such as solar thermal collectors, mechanical equipment, pumps, fans.

-          Passive solar energy-

This happens without the need of any mechanical equipment. This is done using walls, windows, building placement, trees, etc. Example- Passive heating is when your car heats up on a hot day in summers.
