OK, I guess I'll just go with what they recommended and hope they know what they're doing!

The unsubsidized system price is just under $1200/panel. The more powerful inverters will increase system cost by 8% and I'm pretty sure I won't get 8% more total generation. I would fork out the extra money if I knew it wouldn't impact the generation during marginal solar production hours, but...

I can't find any graphs for my panels on the manufacturer's website. There is something called a "pan" file, but I don't have the right software to open it. Will the V-I graphs be in the pan file? I'm not sure I know how to interpret it anyway. Does the V-I graph have light intensity on one of...

Thanks for that, and I am trying to compare panel specs with inverter specs. I have a reasonable handle on the clipping during high irradiance periods but am kind of clueless when it comes to getting a feel for how the low voltage cutoff during low irradiance periods impacts production. I don't...

I recently had a 10 kW grid-tied solar system bid by a local electrical company that also specializes in solar. I live at: 48.5126° N, 122.6127° W and they specified the following system: 25 400W panels with micro-inverters: Silfab 400HC+ Enphase IQ7+ I'm far from being a solar expert but I...
