Solar is now ‘cheapest electricity in history’, confirms IEA
If it&#x27;s not off-topic, I&#x27;m curious to learn how other HN&#x27;ers have approached the planning&#x2F;viability study of getting solar installed at their home.<p>I want to see a spreadsheet to help me plan out energy use, peak need, whether batteries are worth buying, amount I could sell back, number of panels needed, amortized cost against savings etc.  Extra points for thinking tax benefits and estimating the depreciating cost of panels vs the increasing cost of electricity and where the intersection is (or was, if passed) to pull the trigger on a capital expenditure, etc<p>My initial foray so far has been vendors see this as a qualitative decision rather than a quantitative decision with little support for this approach.  For me it&#x27;s purely a numbers game.<p>Anyway, I&#x27;m sure HN&#x27;ers are most likely to be thinking similarly - any pointers or resources to help others?<p>The more I think about it, there&#x27;s probably a startup here...
