“…Historical data was used, since this is an empirical value and captures environmental conditions in the geographical location of interest, which is Thunder Bay, Canada. The cell temperature, Te, is modeled according to [13]: (10) where Ta is the ambient temperature, Rth is a thermal coefficient and G is the irradiance. The battery is modeled according to [9].…”

Habitations in remote areas around the world lack basic infrastructure to achieve an efficient supply chain. Over 90% of roads are unpaved and fuel infrastructure is scarce. The Solarship, a hybrid between a bush plane and airship, was conceived to address this problem. It is a buoyant low-altitude aircraft with an electric power train and wing mounted photovoltaic array. Fully electric operation requires efficient lightweight power electronics to achieve a minimum range of 200 km carrying a 200 kg payload. A detailed system model is developed to explore the impact of wingspan, flight speed and drag coefficient on the flight range. A Partial Power Processing (PPP) converter based on the bidirectional Cuk topology is demonstrated for this application. Due to the PPP concept, the converter is rated for only 26% of 2.7 kW generated PV power. The rating is optimized based on the battery and photovoltaic array voltage ranges. The experimental prototype uses Silicon Carbide MOSFETS and achieves a system efficiency of up to 99.3% with an effective specific power of 5.23 kWlkg.

This paper provides an analysis of the irradiance influence on photovoltaic cell efficiency in dependence on the cell construction, using the standard equivalent circuit describing solar cell. The influence of the series resistance is discussed in details and results of simulations are completed with experimental result obtained by measuring both crystalline silicon and CIS cells in broad intervals of irradiance and temperature.

This paper presents different types of photovoltaic (PV) roof tiles integrating PV cells with roof covering. Selected elastic photovoltaic roof tiles were characterised for their material and electrical characteristics. Practical aspects of using PV roof tiles are discussed, alongside the benefits and drawbacks of their installation on the roof. Thermal resistance, heat transfer coefficient and thermal capacity were identified for elastic PV roof tiles and roof construction built of boards and PV roof tiles, according to valid standards and legal regulations. The resistance–capacity (RC) models of PV roof tiles and roofs are proposed according to the time constants identified for the analysed systems. The energy balance of the studied systems (PV roof tiles alone and the roof as a whole) is presented, based on which temperature changes in the PV cells of the roof tiles working under different environmental conditions were identified. The timing of PV cells’ temperature change obtained by material data and energy balance analyses were compared. The relationship between the temperature change times of PV cells and the thermal resistance and heat capacity of the whole system are demonstrated, alongside environmental parameters.
