Solar energy has become an increasingly popular and sustainable option for powering homes and businesses. However, determining the cost of installing solar panels can be complex due to various factors like panel wattage and local sunlight hours. To simplify this process, we’ve developed the Solar Panel Cost Calculator for Virginia, helping you estimate the expenses associated with solar panel installation in the state.
Formula
The calculator uses the following formula to estimate the cost:
- Energy Produced (kWh) = Panel Wattage (W) x Panel Efficiency x Daily Sunlight Hours (h) x Days in Month
- Cost ($) = Energy Produced (kWh) x Solar Panel Cost per Watt ($/W)
How to Use
- Input the solar panel wattage in watts.
- Enter the average daily sunlight hours in Virginia.
- Click the “Calculate” button to get the estimated solar panel cost.
Example
Let’s say you have a solar panel with a wattage of 300 W, and the average daily sunlight hours in Virginia are 5 hours. Using the calculator, you’ll find:
- Energy Produced (kWh) = 300 W x 0.15 x 5 hours x 30 days = 675 kWh
- Cost ($) = 675 kWh x $2.5/W = $1,687.50
So, the estimated cost for installing a 300W solar panel in Virginia would be approximately $1,687.50.
