What problems can occur with solar panels?

Keep an eye out for these common SolarHot Spots panel problems. Hot spots can occur when a solar panel's energy production pathways are interrupted. The solar cells or photovoltaic (PV) cells that make up your solar panel are very fragile and therefore microcracks can sometimes occur in the panels. One phenomenon that we regularly encounter are “microfissures” in crystalline photovoltaic panels.

These are microscopic tears that are almost imperceptible in solar cells. Microcracks can occur during the production of photovoltaic modules, but also during shipment or due to careless handling during installation. By the way, microfissures do not necessarily cause an immediate loss of production, but can grow over time, for example, due to thermal stress or the influence of seasonal and weather conditions. Larger microfissures will damage solar cells and this will result in a loss of production.

. Since the panel cells are wired in series, this will also affect the output power of the entire panel. As a result, panel performance decreases in direct correlation with the number of broken cells. Several busbars are often installed on more expensive panels to mitigate this problem.

We recently tested several brands of modules in different solar parks and discovered that, on average, microcracks affect a high percentage of the modules, causing a significant loss of production (we have observed a performance deficit of 2 to 3% in relation to microcracks). Some of the most common solar panel challenges result from the build-up of dirt and debris on the panels. If not handled immediately, this will become a problem in the future. The result could be that your solar panels don't produce at their maximum capacity.

The main environmental disadvantages of solar energy are the fossil fuels needed for its manufacture and the wide range of toxic chemicals and rare earth metals needed for each panel. What's worse, damaged solar panels must be handled and disposed of properly due to the toxic compounds used inside them. Billions of dollars can be earned with solar panels, so the industry refuses to face the facts about the use of fossil fuels, the carbon footprint, coal and the hazardous waste associated with photovoltaic energy. Snail footprints have multiple causes, but one of them can be attributed to the use of defective front-facing silver paste in the solar cell manufacturing process.

Currently, battery storage system options for storing solar energy as electrical energy are very expensive. Solar energy for large-scale installations has a long way to go before it can actually be called green energy. For this purpose, the components of the panels (the glass layer, the solar cells and the back sheet) are vacuum-laminated. Things like wind, hail, snow, dirt, and temperature fluctuations are also serious threats to solar panels.

Now that you have a clear idea of the problems with solar panels, here's a practical guide on how to detect if the problems damaged your panel. For homeowners who want to install solar panels, the installation area is not going to be that important, especially when most of the time they are installed on the roof. The fact is, there isn't enough space near most factories and industrial areas to install solar panels to power operations. This means you'll have to pay more for electricity when you need it, in addition to the high cost of the solar system.

The environmental drawbacks of solar panels are the use of land and water, pollution, habitat loss and the use of highly hazardous materials in the manufacturing process that create toxic waste.
