Solar Power: San Diego, worth it?

[Christian Johnston]

I am looking to increase the cash flow of my Quadplex in North Park, San Diego. The energy bill is quite high and I have been considering installing solar to offset some of the costs. I am going to do the actual bath behind the cost difference to determine ROI but I am looking for general advise. Will this increase the value of the property in terms of appraisal, would you recommend a particular company, etc. Thanks so much !
