That's a big growroom- I'd have some other questions:

-Is he an experienced grower looking to expand? If not, I'd go for a much smaller setup to start with

-8kw could produce up to 8lbs/month if done perfectly. Forget looking suspicious to just the power company- that's a lot of weed and a host of other complications not limited to finding a market for it all without getting busted or robbed.

-Those lights are going to put out a significant amount of heat. Your brother will want a SERIOUS air conditioner, there's another big power sucker.

-Don't forget the cost of routine maintenance on the generator, and the wiring for it. If he intends to run it into the panel so that it is correctly wired with circuit breakers etc., there MUST -and I cannot stress this enough- be a safety switch for whenever the power company has to work on the lines near the house, such as when there is a power outage. Same goes for a solar system. The last thing your brother needs is to have to explain why the poor unsuspecting linesman was injured or killed.

If you want my advice as a homeowner, just tell your bro to get a few 600w lamps (less heat, more flexibility), start smaller, and invest the money he's ready to spend on a generator on a really nice security system for his new home. I promise he will sleep better at night.
