The Economics Of Battery Storage For Residential Solar Customers In Southern California, John B. Broughton, Prashanth U. Nyer, Candace E. Ybarra Aug 2021

The Economics Of Battery Storage For Residential Solar Customers In Southern California, John B. Broughton, Prashanth U. Nyer, Candace E. Ybarra

Business Faculty Articles and Research

Battery storage coupled with solar panels became a consideration after the original net metering program in California (NEM 1.0) ended and gave way to the current net metering program (NEM 2.0). Under NEM 2.0, battery storage gives customers under time-of-use (TOU) rate plans the ability to store the excess electrical energy generated by their panels during sunlight hours (when electricity usage and resale rates are low) and then use that energy in the evening when rates are significantly higher. This reduces the amount of expensive electricity that the customer would have to purchase from the grid. It is widely expected …

Hybrid Power Generation System Through Vertical Axis Wind Turbine And Solar Pv, Zeeshan Memon Aug 2021

Hybrid Power Generation System Through Vertical Axis Wind Turbine And Solar Pv, Zeeshan Memon

International Programs

The design of a hybrid electric power generation system utilizing both wind and solar energy for remote area is today’s need. The system has two basic components – one for generation of electricity through Solar Energy and another one for generation from Wind Energy. Even in the case of absence of either of the two sources, the other remaining source could be used to supplement the absence of the former. The power from wind current can be extracted using a vertical axis turbine. Vertical axis turbine is capable of extracting power form wind regardless of the direction of flow. The …


Gases Concept Inventory (Gci): An Instrument Test To Analyze Students’ Mental Models Of The Kinetic Theory Of Gases, Muhammad Guntur Purwanto Aug 2021

Gases Concept Inventory (Gci): An Instrument Test To Analyze Students’ Mental Models Of The Kinetic Theory Of Gases, Muhammad Guntur Purwanto

International Programs

This poster is to promote a Gases Concept Inventory (GCI) as an instrument test to evaluate students’ mental models on kinetic theory of gases. By evaluating mental models using GCI, teachers can assess students’ initial perception and understanding in kinetic theory of gases, so they can prepare the best method to deliver kinetic theory of gases concept to students. THE GCI is analyzed by evaluating its validity, reliability, and difficulty level to prove that GCI is valid and reliable to be used.
