How Much Energy Does a Solar Panel Produce Per Day?

As global warming wreaks havoc across the globe, it’s comforting to know that there is something you can do about it. Installing renewable energy can make a difference if we all work together to implement it.

Are you shying away from installing solar due to the expense? There are ways to ensure you get the best value for your money.

By calculating the daily solar output of solar panels so they closely match your needs, you won’t inadvertently invest in solar panels that you don’t need.

Read on to find out how to calculate solar panel energy production for your home.

Average Solar Panel Energy Production Per Panel

Every solar panel produced has a power rating that describes its capacity for solar energy generation. The most popular solar panel brands have power ratings of between 370 and 400 watts per hour.

These panels produce an average of 4kWh of electricity per day. The trouble is that manufacturers test photovoltaic (PV) system performance under ideal lab conditions.

Your circumstances will impact how much these panels produce in real-life situations.

Factors Influencing Solar Panel Production

There are various factors that can influence solar installation performance. These include:

  • The amount of available sunlight
  • The type of solar panels you choose
  • The age of the solar panels
  • Your roof’s characteristics, e.g., slope and orientation

Sunlight has the most obvious impact on the amount of energy produced by solar panels. You can look up the available sunlight hours for solar panels by consulting a peak sun-hours map for your area.

A qualified solar installer can advise you on the other aspects that influence the performance of your solar panel installation.

Steps for Estimating Solar Power Yield

To get a rough idea of how much solar panel produces per day, you can multiply the solar panel’s hourly production by the number of sun hours for your area. For instance, Edinburgh receives an average of 2.4 peak sunlight hours daily, so a 400-watt-per-hour panel will produce about 930 watts daily.

Once you have your daily total, you can multiply that by 30 to calculate how much electricity one solar panel will produce per month. Comparing this with the power usage on your electricity bill can help you calculate how many solar panels you should install to cater to your home’s energy needs.

In Scotland, many homes can easily incorporate a 4kW system which is roughly 10 panels for a one- or two-bedroom house. Larger homes or those with many energy-sapping appliances will need more.

These calculations may provide a rough estimate of your needs. You must consult a qualified Edinburgh solar installer for a precise estimate of how many solar panels you need.
