calculation of tank loss coefficient

 * use u-vale for tank and for insulation
 * take into account convective resistance of the water-side heat transfer, the resistance of the tank wall, and the combined radiative and convective air-side resistance
 * consider thermal bridges which reduces the effective u-value of a tank

rating tank loss

 * absolute tank losses increase with tank volume
 * divide tank losses by tank volume {kWh/m3}

by the annual demand. (m2 / (MWh/a)) {e.g. 0.5} field area ((m3/h)/m2) {e.g. 0.020} divided by the size of the solar field (m3/m2). {e.g. 2}
 * define constant design ratio and increase energy demand to show difference in system performance
 * RAD (Ratio Area Demand) which is the area of solar collector divided
 * RFA (Ratio Flow Area) which is solar field flow divided by the solar
 * RVA (Ratio Volume Area) which is the volume of the seasonal storage
