Problems solved by technology

Concentrated Photovoltaic (CPV) power plants have higher conversion efficiencies than PV and CSP, but still suffer from intermittent power generation
Concentrated Photovoltaic Thermal (CPVT) systems have high system efficiencies due to improved cooling, but reject heat to the environment or generate low-grade heat with limited utilization

Embodiment Construction

[0064] The present invention forms part of a comprehensive CPVT solution. Such solutions revolve around novel photovoltaic-thermal hybrid receivers. Aspects of these solutions relate to such receivers, cooling devices for such receivers, photovoltaic thermal hybrid systems and methods of operation.

[0065] First, general aspects of the invention are discussed in connection with some high-level variants of the invention (section 1 below). Then, various embodiments are described in Section 2.

[0066] 1. General embodiment of the present invention

[0067] The present invention presents a novel system and method for operating a photovoltaic thermal hybrid system. Such systems and methods rely on hybrid solar receivers equipped with photovoltaic (or PV) modules capable of delivering electrical output power and thermal collectors distinct from the PV modules. PV modules and / or heat collectors are removably mounted in the system. In addition, the collector thermal storage dev...

Abstract

The invention is notably directed to methods of operating photovoltaic thermal hybrid systems (10). A such system (10) comprises: a hybrid solar receiver (20), having a photovoltaic module (21), operatively coupled to the system to deliver an electrical output power (P0) for a power user; and a thermal collector (22) distinct from the photovoltaic module. The photovoltaic module and / or the thermal collector are movably mounted in the system. The system further comprises a collector thermal storage (42) thermally connected to the thermal collector to store heat collected at the thermal collector; and positioning means (30) adapted to move the photovoltaic module and / or the thermal collector. The method comprises instructing (S30) the positioning means to move the photovoltaic module and / or the thermal collector to change a ratio of an intensity of radiation received (S10) at the photovoltaic module to an intensity of radiation received (S10) at the thermal collector.

Description

technical field [0001] The present invention relates generally to photovoltaic thermal hybrid solar energy systems and methods of operation thereof. Background technique [0002] Some definitions are needed: [0003] - Photovoltaics (PV) to generate electricity by converting solar radiation into direct current electricity through semiconductors exhibiting the photovoltaic effect; [0004] - Photovoltaic cells (or PV cells, also called "solar cells" or "photovoltaic cells") are solid-state devices that convert the energy of light directly into electricity by means of the photovoltaic effect; [0005] - Photovoltaic modules (also known as "solar modules", "solar panels" or "photovoltaic panels") are accessories for connected photovoltaic cells; [0006] - Photovoltaic systems typically include arrays of photovoltaic modules, inverters and interconnecting wires; [0007] - Thermal collectors (also called "solar thermal collectors") collect heat by absorbing radiation from th...
