How Many Solar Panels Do I Need?

When considering solar for your home, you might be wondering just how many panels you will need to have installed on your roof. Solar is an amazing way for you to lower your bills whilst also lowering your carbon footprint, but how many panels are needed is dependent on a few things. In this blog, we’ll explain what factors will affect how many solar panels your home will need.

What Factors Influence the Amount of Solar Panels Your Home Needs

Roof Orientation and Direction

The direction your roof faces and its angle influence the sunlight exposure your solar panels will receive. South-facing roofs typically receive more sunlight and therefore generate more energy. If your home does not have the optimal roof orientation, then more panels will likely be required.

Sun Hours

The number of sunlight hours your home receives plays a pivotal role in determining your solar panel needs. Sunnier locations often require fewer panels to generate the same amount of energy compared to areas with less sunshine. If there’s any shading caused by large trees around the property, this will also impact the efficiency of the panels.

Roof Space and Capacity

The available roof space and its capacity for solar panel installation directly impact the number of panels you can accommodate. A larger roof area allows for more panels, meaning you’ll be able to install more panels. Our quote will detail how many panels we advise would be best for your installation.

Annual Consumption

During our quotation process, we’ll ask for your exact usage so we can provide a detailed view of savings, payback period and how many panels we think you’ll need to optimise the benefits of solar. We understand investing in solar can be a big jump, and so we will provide a robust breakdown during the quotation process.

How Many Solar Panels Will You Need on Average

On average, the number of solar panels needed for a residential installation can range from 4 to 25 panels to fully power a home. But this is completely dependent on variables such as roof orientation, sunlight hours, roof size and what your annual energy consumption is. Every household is different, but you can rest assured our solar team will tailor a plan designed to help you get the most out of solar.

Final Thoughts

When it comes to calculating how many solar panels you need, it's essential to consider your roof orientation, sun hours, available roof space, panel size, and annual energy consumption. By nailing down these factors, you'll be well on your way to embracing solar energy in your own sustainable energy journey. Ready to generate your own green energy? Get a quote here!
