Equation Number

Energy Capacity per day

$=TC\times AH$

where TC is the total capacity and AH is the average hours per day for solar radiation.

(10)

Energy generation per day

$=\frac{\text{Energy}\text{capacity}\text{per}\text{day}}{SR}$

where SR is the average solar radiation per day.

(11)

Solar Panel Energy needed

$=\text{Energygenerationperday}\times \text{Panelefficiency}$

(12)

Number of solar panels

$=\frac{\text{Solarpanelenergyneeded}}{\text{Singlesolarpanelpower}}$

(13)

Number of panels for series connection

$=\frac{\text{Invertermaximuminputvoltage}}{\text{SolarpanelVoc}}$

(14)

Total number of strings

$=\frac{\text{Totalnumberofsolarpanels}}{\text{Number}\text{ofsolarpanelsineachseriesconnection}}$

(15)

Total number of inverters

$=\frac{\text{Totalenergy}}{\text{Inverterrating}}$

where the inverter rating is in KVA.

(16)

power generation per year (kWh)

$GP=SR\times CA\times AF\times \eta$

where GP is the, SR is the solar radiation, CA is the total area, AF is the area factor, and $\eta$ is the panel efficiency.

(17)

Capital recovery factor (CRF)

$=\frac{i\times {\left(1+i\right)}^n}{\left[{\left(1+i\right)}^n-1\right]}$
