PV Gap

Vicki Said:

whats the difference between 24v, & 28v solar power system?

We Answered:

This relates to history.
In ancient times (15 years ago) batteries were 12V today the chemistry is better and automotive industry is 14.4V
This is the root cause that newer vehicles will be called 42V instead of 36V
The same applies to the old 24V, now it is called 28V
There are some losses in electrical systems
The loss if directly related to current. So by increasing the system voltage, the current will be less and there will be less losses.
The con is that it is more dangerous and costly for a given size.
But there is a very wide range that overlaps.

Hope this properly answers your question
