Do you have surges in your voltage?
I sold globes for many years, and some location had unstable power sully which caused the globes to burn out much faster if the voltage go too high.
It happens because of damage to the system or breakdowns.

Meet Rachel Brouwer, a brilliant young inventor from Bedford, Nova Scotia, who began her mission to change the world at just 11 years old. She developed a solar-powered water purification system that uses renewable energy to kill harmful bacteria using UV radiation. Her invention includes a smart soybean wax indicator that changes color to show when the water is safe — a breakthrough in affordable water purification technology.
Her innovative work earned her a gold medal at Canada’s national science fair, a top award at the International Science and Engineering Fair, and even led to an asteroid being named after her — an honor reserved for extraordinary contributors to science.
This gives more details of her efforts

I use rainfall exclusively and my signature has a link to more details.
I use 5000Gal storage tanks to clean and hold the water and I have no filters or chemical gizmos to alter the water.
It is not needed if a large tank is used,
Chemical and other suppliers may suggest I am wrong but after 50 years of living this way I am still alive!
And healthy , apart from broken spine, leg and neck, which the water had no role in.
