Optimization of film structure for wide angle incident light for hybridization of photovoltaic and solar thermal power generation

open access: yesNihon Kikai Gakkai ronbunshu
By appropriately determining each layer's refractive index and film thickness, optical multilayer films can control the light spectrum using the interference effect of light. Combining solar and thermal power generation is possible using a heliostat

First Self-Aligned Heliostat Prototype at the Plataforma Solar de Almeria

open access: yesSolarPACES Conference Proceedings
It is a generally admitted fact that the optical aligning process of faceted heliostats in a Solar Power Tower Plant (SPTP), also called heliostat canting, introduces an assembly time penalization as well as a potential error in heliostat optics ...

Evaluating the potential energy of a heliostat field and solar receiver of solar tower power plants in the southern region of Turkey

open access: yesInternational Journal of Renewable Energy Development, 2016
A prior study on the performance of high-efficient models for a heliostat field and solar receiver at various candidate locations (e.g., certain regions in the south of Turkey) helped determine suitable locations for installing solar tower power plant ...

Heliostat cost optimization study [PDF]

open access: yesAIP Conference Proceedings, 2016
This paper presents a methodology for a heliostat cost optimization study. First different variants of small, medium sized and large heliostats are designed. Then the respective costs, tracking and optical quality are determined. For the calculation of optical quality a structural model of the heliostat is programmed and analyzed using finite element ...

A Dormant Giant: Renewable Energy in the Soviet Union and Russia (1970s–Present)

open access: yesThe Russian Review, Volume 84, Issue 2, Page 267-282, April 2025.
Abstract In spring 1981 the Central Committee of the Soviet Communist Party officially sanctioned the start of an “alternative” renewable energy development program in the Soviet Union. Throughout the following decade, some two hundred organizations in the USSR were involved in research and development activities and installing test facilities for ...

Automated Heliostat Installation

open access: yesSolarPACES Conference Proceedings
A concept for the automated installation of heliostats for solar tower power plants was developed with the primary objective of reducing installation costs. Following a discussion on the various types of foundations available for installation, the pile foundation was selected on account of its favourable cost per heliostat.
