Solar Panel Efficiency in SAP 2009 – Products with High Second Order Coefficients
نویسنده
چکیده
For simplicity, SAP 2009 uses only first-order efficiency value for solar heating panels. This works well for most solar panels that have a relatively straight-line efficiency characteristic, however solar panels with poorer insulation and a more curved efficiency characteristic are unfairly rewarded. A simple enhancement of the current calculation is put forward to remedy this anomaly and make the calculation in SAP Appendix H more accurate.

High Efficient Transparent TiO2 Nanotube Dye-Sensitized Solar Cells: Adhesion of TiO2 Nanotube Membrane to FTO by Two Different Methods
In order to fabricate transparent TiO2 nanotube dye-sensitized solar cells, anodically growth nanotube membranes are detached from Ti substrate by a re-anodization method. The membranes are transferred on FTO glass by two different methods. At the first one, 100mM Ti-isopropoxide is used to make TiO2 nanoparticles for adhering TiO2 nanotube membranes to FTO and ...
