Solar Company for Oahu?

Aloha all -- looking to add solar to my new construction in the downtown area. The home isnt built yet.

Ive reached out to numerous companies who have given me various quotes. The lowest being a 9kwh system with 2 batteries and like 18-20 panels to the largest system being over 14kwh with 3 batteries and over 30 panels. Then there's all the stuff in between.

Prices are also super fluxuating. Anywhere between $40k and $70k before rebates.

To be clear, I am not looking for the cheapest company -- Im looking for what will best suit my needs and (hopefully) not be crazy expensive. That being said, ive given the same description and long winded narrative to like 7 companies, so I am confused why my quotes are so different.

I do not want to lease. I want to buy and not have some else reap the any tax benefits that may or may not exist going into next year.

Do you guys have any suggestions on what companies to go through? Maybe share your set up and electricity usage?

A brief description of my home:

Roughly 1500sq ft. 2 Story. Single Family. No previous electricity bills to provide because they'll be completely irrelevant. Regular utility usage for cooking, lights, tv, cleaning, laundry, etc. No pool or anything. There will be split AC systems -- however, only 2 of them will be used regularly. 1 of them (36k BTU) probably 24/7 and a 12k BTU for roughly 12 hours a day (conservatively). Most electricity use will be in the evenings.

I should add, that with PV, I am also looking to put in a hybrid water pump water heater, rather than a solar water heater.

Any suggestions would be super helpful. Mahalo!
