When buying goods for a solar panel brand, the issues at the forefront of people’s minds are commonly topics such as efficacy and wattage. An many times overlooked issue is glass – and the type of glass employed on a solar panel actually does matter.

When you buy a solar panel, it’s a long term investment – it ought to serve you well for decades. While most manufacturers offer lengthy warranties, a great deal of up to 25 years, it’s indispensable to note the manufacturer needs to be around to honour it. There’s still some fly-by-nighters in the solar panel industry, cutting prices by cutting corners on element quality.

While a warranty from a solid company is a outstanding insurance policy, there’s likewise the inconvenience of necessitating to make a warranty assert – pulling the panels down, taking them in – it’s all very disruptive and stressful. It’s best to have peace of mind from the outset and you may only have that if each share of the panel is of the most eminent possible quality.

The dangers of cheap solar panel glass

Cheap glass may cloud over time. Clouded glass principally reduces solar panel efficiency. Broken glass, isolated from being a usual safety issue and even if the glass only cracks, may concede water to penetrate and invent a fire hazard – water and electricity plainly do not mix.

When selecting either a monocrystalline, polycrystalline or amorphous solar panel, be sure to check out the type of glass being used. Look for panels that employ tempered glass – this ought to be without doubt or question stated in the panel specifications.

What is tempered glass?

Tempered glass, likewise known as safety glass or toughened glass, is anything up to six times the strength of normal plate glass. It is devised by thermal or chemical means. We’ve witnessed panels using tempered glass flip over onto rock strewn ground with some strength without breaking.. This is something we evidently do not commend attempting out, but it goes to show how strong the material is. When tempered glass does break, it shatters into little pieces rather than creating long and razor sharp shards.

Flat plate glass in solar panels

This is most often found in for less brands of monocrystalline and polycrystalline panels made by small, comparatively unknown companies; nevertheless it may also be found in well known brands in amorphous (thin film) solar panels that have a glass plate component.

Most amorphous panels may only use flat plate glass due to the way they are constructed. Amorphous panels are ordinarily produced by applying special silicon rich gas called silane at high temperatures directly to the back of a glass plate or to a steel plate. Some makers get around the comparative weakness by using thicker flat plate glass, but this is still not as strong as using white tempered glass.

When buying solar panels, don’t forget that this is an indispensable point to check on – as mentioned, it will have to be without doubt or question stated on the product specifications as to the type of glass used as it’s an essential feature. If it doesn’t, the probabilities are it’s flat plate glass and ought to probably be avoided.

4Nice set-up, could have had the wires all teminated
By Glenn W. Gaarder
Hi- I bought this set-up to keep my Motorhome charged when not using it. It is only 15 watts so can barely keep the battery up to charge if I am actually using any lights or other stuff but it will keep up with the draw of the refridgerator and minimal stuff. My only beef is the controller wires could have all been pre-terminated with connectors rather than having me do that. This was bought as a kit so it would have been nice if there was a connector on the input side of the controller that mated witht he connector on teh solar panel and a different style connector on the output that would be compatible with the cigarette-lighter adapter, etc. In other words- all set up to just plug in and go.
