uch has been said about the conditions your house must meet to be suitable for solar. To make the most of a PV system, your roof must receive much direct sunlight, face south, and be unobscured by nearby buildings or trees. If all the conditions are met – well, congratulations! You can move on to choosing a solar system that matches your needs and budget.
But some homeowners are a bit less lucky as they have one more headache to deal with: the unusual shape of the roof. Fortunately, today’s solar panel market offers solutions even for non-standard cases, and sophisticated roof design is not a barrier to solar uptake.
What are triangular solar panels?
Rectangular panels are the most widespread option, hands down. That’s why people with non-traditional rooftops may be convinced that going solar isn't possible for them. However, triangular solar panels offer a great way out.
These modules are made specifically to cover leftover places where standard solar panels don’t fit, e.g., roof corners of edges. They can also be used for any towering objects on the roof, such as chimneys. Their shape makes it possible to fully cover rooftops without leaving a single empty spot and thus make more effective use of the roof space.
Triangular solar panels are usually combined with traditional rectangular panels to create an optimal configuration. For that reason, it is better to install them all at once to ensure they are perfectly compatible.
Technically, you can even do without rectangular modules and put together your solar system with triangular solar panels only. But that doesn't make much sense because triangle panels cost more, so you will spend more money for the same solar system output. Therefore, the best solution would be to install the main rectangular panels first and then fill the gaps with triangular ones.
Advantages of triangular solar panels
Perfect for homes with space constraints
The most important advantage of using triangular solar panels is space efficiency. They will help you bring into play even the most minor parts of your roof and harvest much more solar radiation.
Opens up solar for the owners of oddly-shaped roofs
With triangular solar panels, even the most unusual roofs can be completed with solar panels, so unconventional roof design is no longer an obstacle to adopting solar.
Provide a more polished look
If you only choose to go with rectangular panels, many gaps and empty spaces may be left between them. Combining these traditional modules with triangular ones, on the other hand, creates a uniform look and offers a more aesthetically pleasing solution.
Disadvantages of custom solar panels
Triangle solar panels also have a bunch of drawbacks, one being higher cost. They are more complex and more expensive to manufacture, which negatively affects the price tag.
A smaller selection of products
The demand for triangular solar panels is low; therefore, only very few manufacturers produce them. The small market results in limited choices, so finding a suitable model may be challenging.
As the triangular panel market is somewhat limited and still in its early stages, there is a lack of data on their long-term performance. This often discourages solar shoppers from purchasing, especially considering the higher cost.
Bottom line: triangle solar panels are ideal for non-typical roofs
Triangular solar panels can become an ideal option for homeowners with non-standard roofs that still want to tap into solar energy. They are also great for those with space constraints, as they help fill the gaps between the rectangular modules and thus utilize maximum roof space. However, if you don’t have any of the limitations above, installing triangular modules won’t make much sense.
