Hi, we will be shipping our solar panels down in a container along with the batteries and all the material. Our solar company guy is asking me this

Do you know the size of main panel?  100, 150, or 200? can you find out what size of a main panel they will use, how much available power will be coming in, and thus I will know what available capacity there will be to tie in solar to deliver power to the house. I have not looked, but assume their power structure in the VI is the same or closely similar to ours in florida....do you know of any difference in voltages, supply, etc. I will research if they do net metering or not and recommend battery configuration accordingly.“

The VI is 60Hz like the rest of North America ad residential power is the same at 120/240V.  Panel size is a variable in each house depending on the size of the house and amount of electric load.

This may be a dumb question, but hasn’t your solar guy been to the house?   If he has and is asking these questions you may need a new solar guy.   If he hasn’t, you need to get them to the house.   Solar guy should be providing you with the materials list of what to put into your container.  Every house is different and solar panels and materials aren’t one size fits all.

Thanks, the solar guy is here in florida. We planned to ship the panels and battery down in our container along w our tile, furniture, etc. in June. But he isn’t familiar w the island. I told him we wont need to heat the pool and dont plan on having an EV charger either, so I was trying to find out what others use for their batteries. He is just trying to figure out how much power to plan for. But yeah, he doesn’t seem to smart on the topic and he owns to solar co. 🤣

There are a bunch of solar outfits locally.  I would switch gears and get with one of the local companies.   One of the biggest hold ups is materials.  If you have to buy them local they can cost a lot.  If you have to order it takes time.   Home construction (and a pretty much everything) is different here.  You really need to get the solar people to the house so they can advise.   It’s just too big of an investment to do it any other way. Vital Solar and Pro Solar are two that pop in my head.  But there are more.   Good luck!

Energy Wise Solutions (Mike Bruno) has done work on STJ as well, great guy in my experience.  I agree, fine someone local, you may think solar is maintenance free but stuff breaks, our inverter bricked itself during a software update and needed replacement under warranty.  Without local support this could have been difficult.  Plus we recently recoated our roof (this time silicone) so the panels needed to be removed and reinstalled after the roof work was done.  It was easy to have the roofing contractor to coordinate with our local installer.  Nothing is ever as easy or trouble free as we’d like.

EWS did my system on STX. Mike Bruno is really the best in the business.
