Warranties on solar panels

Solar panels are a significant investment, so you want to ensure you can enjoy them for as long as possible. Warranties can give you this peace of mind. The warranties available during and after installation can play a big role in your decision to purchase. It is important to choose a solar company that will still be around in the next ten to twenty years, so that you can make use of the warranties should you need to. A solar panel installation consists of different parts and each comes with a different warranty. On top of this, there is a difference between a product warranty and a power warranty for solar panels. What is this exactly?

Product warranty and performance guarantee solar modules

The lifespan of solar panels is typically 25 to 30 years. Our solar panel supplier opts for a 25-year product warranty. This means that if a panel fails within those years of installation, Soly will make sure that it is replaced. On top of this, you get a separate power warranty for solar panels. The efficiency of solar panels decreases somewhat as they age. Our supplier guarantees that the panels will retain at least 84.8% of their power in the first 25 years. Should the panels unexpectedly lose more power, you are entitled to a free replacement or compensation.


Warranty for solar panel mounting material

The mounting material is just as important as all other parts of the solar power system. We have thoroughly tested the materials for quality, durability and weather conditions. For pitched roofs, we use the Esdec ClickFit EVO brand. For flat roofs, we work with FlatFix Fusion from the same supplier. All materials come with a 20-year guarantee.

25 years

Microinverter warranty

The microinverter ensures that you can use the power generated by your solar panels in your home. This makes them a very important part of your solar installation. We use Enphase micro-inverters for a parallel-connected system, which have a 25-year warranty. These ensure safe energy usage, reduced fire risks, automatic shutdowns and efficiency at panel level.


Warranty on your installation

Besides the quality of the products, it is important to have your solar system installed properly and safely. Soly therefore offers a 10-year workmanship guarantee. Should a problem arise with the installation within those 10 years, we will make sure that we solve it for you completely free of charge. We will also take full responsibility for replacing or repairing any part of the solar installation within those 10 years. So, you are assured of the highest quality and a robust system on your roof.

We want you to enjoy your solar energy carefree. That’s why we only work with reliable suppliers and installation companies. Interested in buying solar panels or renting solar panels? Request a free no-obligation quote now.
