Long Life Solar Panels

The general answer for monocrystalline and polycrystalline panels is 25 years.

Long life solar panels.

Luckily the lifespan of solar panels will allow you to produce energy for many years providing a great return on investment. Investing in solar energy is a long term commitment. Crystalline panels are usually guaranteed for 20 25 years while film panels are generally guaranteed for only 2 5 years. Solar panels offer homeowners a great way to reduce their carbon footprint.
