System Sizing Calculator
With yachts and their limited "roof space" for solar panels it is often the case that the decision as to which panel to install (and how many of them) comes down to what will physically fit and seeing how much this will offset your power usage aboard. This is where Maxeon cell technology excels, with their high efficiency solar cells it means more power in less space!
That said we often get asked the question, "How many panels do I need?" It's always a good idea to have a grasp on what your power usage is aboard and the online calculator below will help you determine power usage aboard and recommend a solar array size to help offset it. If you then toggle the options of the flexible & fixed frame solar panels we have available it will recommend the number of panels to install.
​
We hope you find this calculator a useful tool, play around with different scenarios where power consumption will vary:
1. Sailing in the day
2. Sailing at night
3. Anchored in the day
4. Anchored at night
You can print or download your results and please don't hesitate to give us any feedback or contact us with any questions you may have.

In our experience "more solar is always better". We often will sell more panels to boat owners, but I don't think we have ever had anyone say they have too many solar panels and would like to return some!

To go one step further you could create your own power usage table and go into more detail on the items powered aboard. Based on our time and experience sailing, on short trips and living at sea, we have created a Power Usage Chart below. You can see more details on what each system could power on your weekend or live aboard sailing adventure.
