Worried about solar panels and storms? Worry not, solar panel systems are incredibly durable and require little to no maintenance over their productive lifetime – which can span 25 years or more.
Many people in regions that experience a significant shift in weather often ask if it’s necessary to remove the panels or account for additional maintenance. Generally, the answer is no. Why? Because your panels can withstand severe storms and to be self-cleaning, if they are mounted and secured to your roof at an angle of 15 degrees or more.
More importantly, Florida code requires the entire solar system to pass 180 mph+ wind loads as part of the inspection to operate.
But in the event that something does go wrong, your solar photovoltaic system components have very long warranties that would cover replacement and repair costs.
Adding solar panels to your home is a long-term, low risk, high return way to invest your money and you can be prepared for a storm any time of year with a Tesla Powerwall backup battery system.
Solar Panel Warranties
Solar panel manufacturers provide a range of warranties that guarantee you will have support and coverage in the unlikely event of an issue, such as hail or falling palm tree branches or even a hurricane.
Power output warranties guarantee that panel performance won’t fall below a specified level over the term of the warranty (usually 25 years). For instance, a manufacturer might provide a warranty to guarantee that peak power output won’t fall below 85 percent for 25 years. Some manufacturers will also include an additional warranty that promises a higher output level over a shorter period of time.
As an example, a secondary warranty might guarantee no less than 90 percent of initial power output for the first 10 years.
Panels typically come with a workmanship warranty that protects consumers against defective panel parts, generally for the first five years of operation. Inverters also come with warranties, usually for 10 years.
Vinyasun prefers to install systems using SunPower solar panels, which can withstand up to 170 mph wind loads because they are the highest-wattage home solar panels available, period.
