A Model to Improve the Implementation Standards of Street Lighting Based on Solar Energy: A Case Study [PDF]

Energies, 2020
This paper aims to improve the implementation standards of solar-energy-based street lighting in Indonesia. A model framework was developed to assess existing conditions regarding the level of lux, the distance between poles, pole height, and lamp power.

Improved Measurement of Solar Neutrinos from the Carbon-Nitrogen-Oxygen Cycle by Borexino and Its Implications for the Standard Solar Model [PDF]

Physical Review Letters, 2022
We present an improved measurement of the carbon-nitrogen-oxygen (CNO) solar neutrino interaction rate at Earth obtained with the complete Borexino Phase-III dataset.

Detecting beyond the standard model interactions of solar neutrinos in low-threshold dark matter detectors [PDF]

Physical Review D, 2022
As low-threshold dark matter detectors advance in development, they will become sensitive to recoils from solar neutrinos which opens up the possibility to explore neutrino properties.

3D Solar Irradiance Model for Non-Uniform Shading Environments Using Shading (Aperture) Matrix Enhanced by Local Coordinate System

Energies, 2023
Building-integrated photovoltaics (BIPVs) and vehicle-integrated photovoltaics (VIPVs) receive solar irradiance through non-uniform shading objects. Standard scalar calculations cannot accurately determine the solar irradiance of BIPV and VIPV systems ...

Single Diode Solar Cells—Improved Model and Exact Current–Voltage Analytical Solution Based on Lambert’s W Function

Sensors, 2022
There are three standard equivalent circuit models of solar cells in the literature—single-diode, double-diode, and triple-diode models. In this paper, first, a modified version of the single diode model, called the Improved Single Diode Model (ISDM), is

Stellar evolution and the Standard Solar Model [PDF]

EPJ Web of Conferences, 2020
This contribution is meant as a very brief introduction to the principal concepts of stellar physics. First the main physical processes active in stellar structures will be shortly described, then the most important features during the stellar life-cycle

Updating standard solar models [PDF]

, 1997
We present an updated version of our standard solar model (SSM) where helium and heavy elements dif- fusion is included and the improved OPAL equation of state (Rogers 1994; Rogers et al. 1996) is used.
