Solar Panel Structures: Choosing Pre-GI or HDGI for 25 Years of Strength
Listen to the story
Solar panels need a strong structure to hold them. This structure is usually made of metal.
There are two common types: Pre-GI and HDGI. Both protect the metal from rust
Pre-GI means the metal gets a thin coating before it is made into shape.
HDGI means the metal gets a thick coating after it is made. This makes HDGI stronger.
Experts say a good structure can last 25 years. This is the same time a solar panel usually works.
Choosing the right structure is very important. It helps the solar panel make electricity for a long time.
Some people who use solar panels pay very small bills. One report said a bill was only ₹800.
But some users still pay a fixed charge every month. This charge does not change even with solar power.
About 1.37 lakh people pay this fixed charge. Together, they pay ₹10 crore every month.
Different solar panels also make different amounts of electricity. People should learn which panel works best.
