How to face the sun with photovoltaic panels
South-facing solar panel systems almost always generate the most electricity, but east-west roofs can work well for solar, too. The direction is more important than the angle. Angle is rarely a make-or-break factor, and most roof tilts will work fine—though there are some.

How long do rooftop photovoltaic panels last
Solar panels typically have a lifespan of 25 to 30 years. During this time, they maintain a high level of performance, although efficiency may gradually decrease by about 0.
FAQs about How long do rooftop photovoltaic panels last
How long do solar panels last?
Solar panels offer homeowners a great way to reduce their carbon footprint. Luckily, the lifespan of solar panels will allow you to produce energy for many years, providing a great return on investment. You can count on most photovoltaic solar panels to last 25 years before they begin to noticeably degrade.
How long do monocrystalline solar panels last?
Generally speaking, the degradation rate of monocrystalline solar panels is 0.5% per year. This means that, after 30 years, most monocrystalline solar panels on the residential market will produce 87% of their original power output. To learn more about solar, check out our rundown the top 17 facts about solar panels.
How long do solar inverters last?
Solar inverters have a typical service life of 10 years. This means your solar panels will still have 15 years of guaranteed power output when your first inverter reaches the end of its service life. If you're considering a solar power system with energy storage, home batteries also have a typical service life of 10 years.
When does a solar panel stop working?
However, it doesn't necessarily mean that a solar panel completely shuts down and stops working between year 30 and 40. A solar panel's efficiency (and consequently its output) falls by a very small amount each year, and so it just naturally reaches a point where output has fallen too low for the panel to be worth having.
Should I replace my roof after installing solar panels?
The last thing you would want is having to replace your roof after installing solar panels. Removing and reinstalling a solar panel system is a complex procedure, and in many cases, you will void warranties. Ideally, solar panels should be installed on roofs that will not need a replacement during the next 25-30 years.
Do solar panels expire?
There is technically no expiration date on solar panels. However, over time, they naturally tend to become less efficient at producing energy. Some panels can also break due to physical damage from extreme weather conditions.
