Solar cell price is now virtually irrelevant because the majority of cost is installation.

For example on a $10k install, if you bought the solar panels yourself you'd pay $2k for the panels.

So even if solar panels were free, it would only save 20%.

Cheaper inverters and batteries would be the real game changers at this point. At least for DIY home solar.
