What Is A Solar Panel
Well the answer is very simple to explain. Many people do
not fully understand the basic principles of quality verses cost.
So a solar panel starts off life as a billet of manmade
silicon. This is then segmented and divided into wafer thin silicon wafers by
factories that produce solar panels. The division of this silicon refers to the
quality of that wafer. The lower quality of wafer will then produce a less
efficient performance ratio. We have found that some companies provide efficiency
based on the cell performance, whilst other higher end manufacturers offer the
performance statistic based on the overall build. The later is the most
consistent option as the cells when connected together loose a percentage of
performance due to voltage drops through the series connections. So with the
lower graded cells, the greater the overall performances drop.
You may have heard of tiers, this is how a finished solar
panel is graded. Tier 1 being the best as far as build quality and performance
is concerned at above 16% efficiency. Tier 3 grading being the lowest
performer, the differential is not large but the percentage gap has a greater
hidden meaning. Once manufactured each panel is tested to revile its true identity.
Only then is it possible to provide a certificate that matches this
performance. So solar panels are not all alike.
So now that this is understood, the description of a solar
panel should be easier to identify. Let us go back to tier 1, as this outlines
the best product available. The tier 1 signifies overall performance ratio
based over a 25 year life period. This performance provides time line steps as to
the way particular solar panels perform over time. As all solar panels reduce
in performance after the first year of operation, understanding how much these
actually fall is the key to obtaining the best performing product within a
given tier scale or product value.
Tiers performance and percentages. The lower range panel is
probably the best example to explain in so far as the use. This range of panels
or efficiency is often connected in series to provide lower cost installations.
Whereas the mid to higher efficient panels are used to create higher dividend yields over a 20-25 years period. This is something that is down to each individual customer as in many cases the cost is the biggest influence when purchasing a solar panel.
This to one side, one should understand the hidden performance
issues surrounding every solar panel grade. Let us take the least efficient;
very quickly this performance can dramatically drop. Usually after the first
year by a high percentage, and then fall in performance again quickly over
subsequent years quite dramatically. Performance after 5 years could be as much
as 30% lower in some cases than the initial performance check when
manufactured. Using this lower tier of panel could dramatically reduce the
return on investment (based on yield calculations).
Tiers are important in many other ways, as it outlines the
build quality, material used such as cell grades, glass, frames, backing media
and variants on surface treatments of the aluminium frame structures and glass.
But most important of all the amount of years the production company has been
established in the manufacturing of solar panels and do they offer in house
production of silicon cells.
Our company believe that the only way to treat our customers
is to offer the very best products, as this should guarantee the outcome of future
orders. We only provide tier 1 and higher end tier 2 products to our customer
base. As our goal is to always achieve maximum potential gain, this pushes
maximum power towards the grid requirement or battery storage facility.
I hope this explains my views on what is a solar panel
question for our customers. Solar panel prices
