Parameter

Description

A

A monthly rate factor given in dollars per kWh

B

A monthly STD rate factor given in dollars per kWh

$B_R^{\left(P\right)}$

A monthly peak TOU rate factor given in dollars per kWh;

R stands for either SUMMER or WINTER rates

$B_R^{\left(O\right)}$

A monthly off-peak TOU rate factor given in dollars per kWh

R stands for either SUMMER or WINTER rates

C

A fixed monthly payment given in dollars

${\theta }_P$

Excess peak solar production factor for TOU,

if $v_j^{\left(P\right)}>u_j^{\left(P\right)}$ ${\theta }_P=0.75$ otherwise ${\theta }_P=1.05$

${\theta }_O$

Excess off-peak solar production factor for TOU,

if $v_j^{\left(O\right)}>u_j^{\left(O\right)}$ ${\theta }_O=0.75$ otherwise ${\theta }_O=1.05$

${\theta }_T$

Excess solar production factor for STD,

if $v_j>u_j$ ${\theta }_T=0.75$ otherwise ${\theta }_T=1.05$

$\theta$

Local tax factor, $\theta =1.05$ for grid STD
