Solar photovoltaic panel missing corner

Are solar panel backsheet defects on the rise?

Here’s the bad news: according to the 2019 Global PV Reliability Report from DuPont, solar panel backsheet defects are on the rise. The good news is that Aztech Solar uses only PV panels with backsheet materials that have been tested for damp heat and thermal cycling reliability – ensuring maximum water insulation.

Are solar installers cutting corners?

This has resulted in some inexperienced installers cutting corners and producing precarious solar installations. According to an NSW Fair Trading inspection, 18.5% of solar installations have major defects (122 of 658 cases). Minor defects were also spotted in 418 installations, or 63.5% of all properties inspected.

What happens if a solar panel is left unchecked?

Portions of backsheet could show through and start a fire if left unchecked. To eliminate hot spots, reliable, skilled solar panel fitting companies like Aztech Solar check for imperfections on each solar cell before installing them. Broken cells and poorly soldered ribbons get automatically discarded. 2. Microcracks

Should you slice off a monocrystalline PV panel?

The more you slice off, the closer to a square shape you get, and the more working area you can squeeze into your monocrystalline PV panel. The less you slice off, the less material you waste and the cheaper are the cells to manufacture.

How do I know if my solar panels are delaminated?

If you see dark spots on your panels, this could be a sign that your panels are undergoing delamination, and you should contact your installer for an inspection. Micro cracks are tiny tears in solar cells stemming from haphazard shipping and installation or defects in manufacturing.

What happens when a solar inverter fails?

A solar inverter failure can cause problems as it is responsible for converting DC power from the solar system into AC power for use in a building or the grid. If the inverter fails to produce the correct amount of power, it may have a blown fuse, a tripped breaker, or broken wires.
