Panasonic HIT 325

Where are you guys pruchasing the large Panasonic solar panels from?

I bought from altestore.com. I think they were the last 3 they had and would carry.
It looked like they were going to the HIT330 watt from now on. Both were on sale this month, and the best price I could find. Price of the panel plus freight was less than their closest competitor.

Thanks Battery Pro for the information and correction on both the panels and Lithium Batteries. It's nice to get the straight scope on the myths.


What type of mounting hardware will you be using on this 45' motorhome? I'm still leaning towards the 80/20 product line, only because I would like to be able to tilt the panels a little easier and I'm concerned about the support that they will need.

While I agree in general about your comments related to Li batteries, I still think that it is useful to sub type the Li batteries into three general categories (for safety risk reasons)
- LiCo - among the most powerful, and risky to use.
- Li - Ion - Yes it is not a perfect description, but it helps to categorize this mid range risk versions
- LiFe types - Slightly lower performance, but usually substantially lower risk

Most people can digest and adequately understand this level of Li battery information in their decision making. I find battery chemistry and construction details very interesting, but no one else in my family is all that interested beyond that level of detail.

I understand that different chemistries have different risks. That’s not the point of my previous comment. It seems like you are still suggesting that there is some difference between Li-ion and Lithium Iron by your categories. There is not. Lithium iron, or LiFePO4 or LFP or other acronym's are lithium ion batteries.

There are two categories of Lithium batteries: Lithium metal (lithium anode) and Lithium Ion (lithium cathode). No matter how many chemistries you are talking about or the relative safety of any, it will either be Li-ion or Lithium metal.

Gross ignorance is abundant in this world today due to anyone being able to write anything and publish it. For example, this website seems authoritative but is in complete error about the subject: Lithium Ion vs Lithium Iron Batteries
