Learn how to calculate the solar panel size per kw for your home based on your energy usage, sun hours and inefficiencies. Follow six steps to size a solar sys
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. Here''s a step-by-step overview of the process we follow when sizing solar systems for our customers.
Note: This article applies to grid-tie systems only. Off-grid systems are more complex because battery banks are sized independently of the solar array, so no two systems are quite the same.
When sizing a solar system, follow these steps to find out exactly what will cover your energy needs. If you''d just like a quick estimate without having to work through the math, feel free to use our solar calculator instead.
Statistics show that 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:
Take the daily kWh target from step 2 and divide it by the number of sun hours in your location. For example, in Anaheim, CA, where GoGreenSolar is headquartered, we get about 5 sun hours per day:
The output of solar panels drops slightly each year, which is outlined by their performance warranty. If your solar panel''s performance warranty guarantees 80% performance after 25 years, then their degradation rate is calculated as 20%/25 years, or 0.8% production loss each year. By the end of its lifecycle, a 400W-rated panel would only output 320 watts.
In addition, solar panels are tested in ideal conditions ‒- a temperature controlled lab with nothing obstructing the panels. In the real world, solar panels often fall short of these lab-tested conditions, meaning they produce a bit less power than their wattage rating.
Because of these factors, it''s wise to budget extra solar capacity so that you can reach your target production figures after accounting for the inefficiencies of the system.
