The different independent studies that tackled the question of solar modules degradation end up with an average of 0 8 per year.
First solar panel degradation.
On average solar panels degrade at a rate of 1 each year.
Today first solar is producing cdte modules with 16 efficiency and a manufacturing cost below usd 0 46 watt.
Significantly more energy in real world conditions.
Although crystalline solar power panels are often sold with 25 to 30 year lifespan guarantees those 30 year old modules won t be performing as well as they did on day 1.
Manufacturers realize this so solar panels come with a power output or performance warranty that usually guarantees 80 production at 25 years.
However a study conducted by the national renewable energy laboratory nrel shows a more accurate picture of solar panel degradation.
From raw material sourcing through end of life module recycling first solar s renewable energy.
First solar s series 4 tm and series 6 tm modules generate more energy for your solar plant with a module proven to deliver significantly more usable energy per nameplate watt than competing technologies.
The company s integrated power plant solutions deliver an economically attractive alternative to fossil fuel electricity generation today.
That s backed up by the solar panel manufacturer s warranty which guarantees 90 production in the first ten years and 80 by year 25 or 30.
First solar is a leading global provider of comprehensive photovoltaic pv solar solutions which use its advanced module and system technology.
With an average of 3 5 after 9 years the degradation of the 16 modules tested would translate into an annual degradation of less than 0 4 which would position aleo in the very good performers among its peers.
Factory rated power doesn t always equate to performance in the field.
This study took a look at the degradation rates for almost 2 000 solar systems across the world in a variety of climates and found that monocrystalline.
Most solar installers build into contracts an expected photovoltaic efficiency degradation rate that typically doesn t exceed 20 over the contract s term.

First solar has test programmes and quality.
Pv solar plants using first solar s advanced thin film series 4 modules enjoy better energy yield proven reliability and industry leading durability.
Performance declines as solar cells experience degradation due to unavoidable circumstances like uv exposure and weather cycles.
