About How to choose the capacity of photovoltaic panels
Statistics showthat most people consume more electricity during the summer and winter, when the A/C or heat is running. If possible, collect your last 12 months of electric bills, then tally up your kWh usage and divide by 12 to get a monthly average.
Next, divide your monthly kWh usage by 30 to estimate your average daily kWh usage. The average American home uses about 900 kWh per month, so we’ll use that in our example: 900.
Sunlight availability affects how much energy your solar panels generate. Use NREL’s GHI maps to see how many sun hours you can expect to get in your location. Below is NREL's map for average annual sun hours in the.
Most grid-tie homeowners choose to offset 100% of their energy needs with solar. But it is also possible to start with a smaller system for partial offset, and then expand down the line as the budget allows for it. If partial offset is your goal.
From there, we need to add a bit of overhead to account for inefficiencies and degradation rate of the panels. The output of solar panelsdrops.
Determine the solar panel capacity by dividing the daily energy production requirement by the average daily sunlight hours. Account for panel derating to factor in efficiency losses.
To calculate the size of your solar photovoltaic system, take your daily kWh energy requirement and divide by your peak sun-hours to get the kW output you need.
Solar PV System Sizing: Step By Step GuideStep 1: Estimation of the solar irradiation on-site .
Online solar calculators can give a rough estimate of how much solar you need to power your home, but you may want to perform your own sizing calculations to fine-tune your choices.
To get an idea of how much solar you need, examine your utility bills to find out your average monthly electricity consumption in kilowatt hours (kWh). Divide this by 30 to estimate your daily usage.
