Know Your Annual Electric Usage
Your electric usage is measured in kilowatt-hours (kWh), and it’s easy to find out what your usage is. Check your most recent electric bill and look for the “Total kWh” for the entire billing period. This is the number of kWh you used in that period.
To determine how many solar panels you need to power your home, you will need to calculate your home’s energy usage and match it with its production ratio of the solar panels for the roof.
A typical home uses about 30 kilowatt-hours of energy per day. Solar panels have a production ratio of about 2 kilowatt-hours of energy per day per panel. So, if you want to power your home with solar panels, you will need about 30 panels.
However, roof solar panels only produce electricity when the sun is out, so you need to factor in solar panel efficiency. In a place with less sun, solar panel efficiency is lower.
Decide On Your Solar Wattage
To answer the question of how many roof solar panels you need to power your house, you must first decide on the solar wattage you wish to use. Solar wattage is a measure of the amount of power that a solar panel can produce. For example, a 370-watt of solar panel can produce from 1.4 kWh to 1.9 kWh of electricity on an average day.
Look Into the Production Ratio
To figure out how many solar panels you need to power your home, you need to look into the production ratio. This will tell you how much electricity your panels produce in relation to how much sunlight they receive. If you have a high production ratio, you will need fewer panels to produce the same amount of electricity as a home with a lower production ratio.
