10 year solar installation warranty
Solar panel mounting systems are bolted into the structure of the roof which requires roof penetrations, depending on the quality of the solar installation the process of penetrating the roof can cause the integrity of the roof to be compromised. If your solar installer did a bad job, you could end up having a leaky roof, would that be horrible?
Here in California, when a solar system is installed by a solar contractor, the installation itself has to be covered by a 10 year warranty. If anything goes wrong with your system, the contractor would be liable for 10 years to fix the problem without any cost to you. So if you are going to hire a solar contractor to install your solar electric system, make sure you review the terms of their 10 year installation warranty. Do you think a 10 year installation warranty is enough?
