Off-grid solar system helps him solve the problem
The cost between solar system and diesel generator
As his place is full of sunshine, and not much cloudy day. That’s why perfect to use solar energy. We help him calculate how many solar panels he need and how much battery power he needs at night.
He uses about 120kwh each day, because the pumps and freezer is 24hrs running, non stop for his seafood.
As he wants the system can run more than 6 years. So that means about 30% battery DOD each day.
And we design a 30kw off-grid solar system with 78pcs 380w mono solar panel and 60pcs 200Ah gel battery.
This is one time investment, about $29,000 ex factory. Solar panel life span is more than 25years, and battery can be run about 6 years. Battery price is about $11,000, solar panel price is about $10000. If he use the system for 12years, and at the 13t h year, he not use solar system any more. And sell all the solar panels as second hand in the rate of 0.8..
That’s means his solar system about
($29000+$11000 - $10000*0.8)÷=$2600 each year.
If he use diesel generator in the next 12years, it would be at least $4000 each year, and consider the diesel cost and labor cost is getting higher each year, it would be $4600 to $4800.
