So, I've been diving deep into the world of solar ROI calculations (yes, my spreadsheets are a thing of beauty now, haha). But here's the thing: all those online calculators and formulas make it seem so straightforward! Like, plug in a few numbers, boom, instant savings prediction.
But something feels off... like they're not capturing the full picture.
Here's where my gut is clashing with the algorithms:
Most calculators assume constant energy prices. But haven't we learned ANYTHING from the past few years? Who knows what energy costs will do!
They rarely factor in maintenance or potential issues. What about inverter replacements, panel cleaning, unexpected repairs?
And what about the TIME value of money? Shouldn't we be discounting future savings somehow?
Am I overthinking this? Or are these calculators just glorified marketing tools? 🤔
Solar veterans, I need your real-world wisdom!
How closely did your actual solar payback match the initial estimates?
What factors did the calculators NOT account for?
Any tips for making a more realistic ROI assessment?
Let's cut through the marketing fluff and get real about solar payback! 💰
