Review of the impact of temperature coefficient in solar technology and comparison of N-type (HJT) and PERC. Best performance solar panels.
The temperature coefficient tells us the rate of how much will solar panel efficiency drop when the temperature will rise by one degree Celsius (1.8 °F). For example, when the temperature coefficient is minus 0.5 percent, it means that efficiency decreases by 0.5 percent for every degree above 25 °C (or every 1.8 degrees above 77 °F).
Than ran at 99 degrees celsius. Then I took off the stock cooler, removed the old paste with Thermal Material Remover from Arctic Silver and applied Cooler Master thermal paste. That is now running at 99 degrees celsius. What am I doing wrong? Edit: The temperature is at the same at idle and load, both 99 degrees celsius.

Yes, 99 degrees Celsius is considered to be too hot for a CPU. The maximum temperature for most CPUs is around 70 to 80 degrees Celsius. When a CPU reaches a temperature above its maximum, it can start to throttle its performance to prevent damage, which can result in decreased performance or even permanent damage.
One question that frequently comes up is whether temperature affects a panel''s efficiency and output. Well, the answer is yes – temperature plays a significant role.To understand why, we need to go back to basics. Solar panels work by converting sunlight into electricity through photovoltaic (PV) cells. When photons (light particles) from the sun hit the …
The data reflect how much warmer or cooler each region was compared to a base period of 1951-1980. (The global mean surface air temperature for that period was 14°C (57°F), with an uncertainty of several tenths of a degree.) The image below shows global temperature anomalies in 2022, which tied for the fifth warmest year on record.
On the Fahrenheit scale, the freezing point of water is at 32 degrees F and the boiling point of water at 212 degrees F. This means that there are 180 degrees between these two points. Celsius has the freezing point of water at 0 degrees C and the boiling point at 100 degrees C making the interval between the points 100 degrees.
