I went with Sullivan Solar Power (and have referred people from this site to them as well) and have been very happy. I purchased the system outright — many of the other solar companies, especially Solar City, were pushing the solar lease which essentially replaces SDGE with Solar City as your power company. If you are interested in getting a quote from Sullivan, shoot me a PM and I’ll out you through their solar referral network which will give both you and I a $500 referral bonus check. This is a better deal than $500 off the system due to the tax credit impact (i.e. $500 off the system is only worth $350 after considering the 30% tax credit).
