SOLAR SIZING WORKSHEET

SITE NAME DATA POINT

AVERAGE YEARLY BRIGHT SUNSHINE HOURS (BSH)

ADJUSTED (+ or - a +5 percent) TOTAL BSH

AVERAGE PEAK HOURS PER DAY (total BSH x 0.0017) = B =

AVERAGE ANNUAL TEMPERATURE (at monitor point) c =

ADJUSTED FOR SITE (c - adiabatic lapse rate) +20 = C =

DUTY CYCLE (shown as a decimal, eg. 8% = .08) = dc =

TOTAL DAILY NORMAL OPERATING HOURS a = h

TOTAL STANDBY CURRENT (24 x Rx(I)) = b = Ah

TOTAL TX CURRENT (a x Tx(I) x dc) = c = Ah

TOTAL DAILY REQUIREMENT (b + c) = r = Ah

REPEATER OPERATING VOLTAGE V = Volts

BATTERY TYPE VOLTS PER CELL v = Volts

NUMBER OF CELLS REQUIRED IN SERIES (V/v) = VI = cells

ONE BANK OF CELLS WILL GIVE (100 / r) DAYS OF STORAGE

CHARGE VOLTAGE PER CELL CV = Volts

REVERSE CURRENT DIODE OR REGULATOR LOSS D = Volts

NOMINAL PANEL VOLTAGE (from manufacturers data) = m = Volts

PANEL O/P VOLT REQ’D (D+R+(VIxCV)+(0.004(C x m))) = L = Volts

PANEL CURRENT (from man. power graph) at L volts = M = A

MODULE CURRENT PER DAY (B x M) = M1 = A

NUMBER OF PANELS REQUIRED = (r / M1) = modules
