Yes, totally agree. I'm just so glad that the system has great monitoring abilities so that when I sue them, I have a very quantifiable, easily proven claim. I just hope I get connected to the grid before the damages get too high for small claims court because I don't want to deal with a full lawsuit or binding arbitration.


I'm cautiously optimistic that I'll be compensated for every dollar of power that I generate now, so I still get excited to see big production numbers. So far the most I've made in one day is 79kwh but looking forward to more!

What was your power consumption with Coned? Have you estimated how many years it will take to break even after the financing costs and everything?

My consumption is very high. I have well water, pump-style septic, electric hot water (heat pump), and electric heat (heat pump). I will use more power than my solar system produces on an annual basis. In NY state, with the incentives coupled with the very high rates that Con Edison charges, everyone's break-even on solar installations is between the 5 and 7 year mark, depending on whether electric rates go up in that period. Using today's rates, my break-even is sometime in year 6. However, from a cash perspective I profit every single month since the savings are higher than the loan payment.

The break-even can be less if you partially DIY, or do the project management yourself. My total installation was close to $40k but the cost of the equipment is around $15k. If you subcontract the electrician and installer, and learned the permitting process, you could probably put the same system up for $25k or so. But the administration would be very, very time consuming and difficult.

Interestingly, north of Con Edison territory where electric rates are lower, solar has a much longer break-even since the power saved is worth less but the installation costs are relatively the same. In Con Ed territory, solar really is a no-brainer as long as you have a sunny roof.

Financing costs are a red herring- at a 2.9% interest rate, my financing "costs" are actually savings since I'm earning more than 2.9% on the money that I didn't spend on the system.

Hope this helps!

This is the most important thing to remember, never over-produce. Con ed would only buy your excess power for the rate it buys power from wholesale producers like Indian Point, not the kilowatt rate it charges customers. Power is marked up 400-500%. So when you pay .20 per kw (made-up number), con Ed would only pay you .04 for that same kW. The cost to build a system is based on saving on the retail rate you pay, not the dirt cheap wholesale price it buys from you. Its not cost effective to buy power to sell on a home system.

Anyway, sounds like you are doing great. I am as well. I am about to enter year 5. Year 3, I maxed out at 99% produced on the year to year. Years 4 I was at 92% and think this year looks to be in the 95% range. I built it to hit 95%. System will be paid off with savings in about 20 months. Then I am looking at 12-15 years free power. Maybe more.

Thanks, seems like it's something worth considering. We just bought a year ago and plan to be in the house for 15+ years. We have a lot of large trees and our roof faces West-Southwest so I'm not sure how great it would be for a solar array. Plus I have serious fears about punching holes in a brand new roof to install panels, especially after all the horror stories about low quality solar installers.

The trees and angles may kill it for you, but call someone to see. I used Sunrise Solar. They will come, evaluate and tell you whether its feasible or not. Always get quotes from multiple contractors, but I used them. Sunrise Solar Solutions LLC Solar Energy Design & Installation by Sunrise Solar Solutions - Sunrise Solar Solutions - Solar Panels in Westchester, Solar Panels in Rockland County, Solar Panels in Hudson Valley, Solarize NY NJ CT LI, Solar Energy Desi

As for the roof thing, that is not really the way roofs work. The barrier remains secure.

I agree- the holes aren't an issue, especially in NY where the government incentives require contractors to warrant the system, including roof leakage, for a long time. Trees are your biggest concern; the roof angle can be overcome.



Also, I agree on Sunrise- I got a quote from them during my install and kick myself for not using them, I got a very good vibe from the person I spoke with.

You know, they have been awesome. When I changed cable providers I forgot to reset the solar communication box to the new wifi. I got a call the first business day asking what happened to my signal. I told them I would reset it that night, but I forgot. They sent a tech out to do it the next day for free. Amazing service, great people. Sorry you skipped on them. Lol.
