In a couple weeks I'll be pulling the trigger and getting solar for my new house in NJ. Going to do the 10 year $0 down loan option. So far I've narrowed it down to Tesla and Sunpower who are both coming in at $3.52 per watt for their latest panels. I'm going to try and get another quote for Tesla to match but was wondering if anyone knew the "cheapest" competitor panel they'd be willing to do a price match on. For example one installer quoted me at $3.20 a watt for Hanhwa Q cell panels. Also, are there any gotchas in the contract I should be aware of or things I should ensure are included in the contract and/or just general tips or tricks?
