[quote=Anonymous]I installed 56 solar panels on a farm building I built 3 years ago.  I don’t have a power bill 9 months of the year.  Runs out in February usually.

My concern is your pricing.  My 56 panels were around $50k so $25ish with tax credit.  But given I have a 3800 sf. house and 2 barns with heated tack rooms, and 10 heated livestock waterers (necessary in my climate, upper MW).  They will pay for themselves in 5 years, maybe less with rising energy prices.  Lifespan is 15-20 but they get less efficient with time.  Another concern is your west-facing placement with trees….you lose a lot of efficiency as soon as you veer from direct south.  Ours are just a few degrees off South and I was told the angle reduces efficiency by 5% from ideal.  Based on the dirt work involved, it made more sense to do it on that angle anyway.  A west-facing roof…I’d question whether it was worth it.

I do not have a battery.  We don’t often lose power, but I have my house wired to where I can run the well pump, heat, and fridge easily on a portable generator.  Much less expensive and more practical.  At 10k for the battery, not worth it to me.  [/quote]
