y: watts from your railing · x: one honest day
This is what your railing would have made today.
Balcony solar is a curve, not a gadget: it rises with your sun, dips with your neighbor's building, and pays rent in shaved base load. Change the inputs and watch your own curve redraw, payback included.
W
first light
The base-load nibble begins
Router, fridge, standby: the panel starts paying before you are awake. Self-used watts are the profitable ones.
midday peak
Peak is capped by law, and fine
Plug-in sets are limited per country (often 800 W). Every pick lists the rule it fits so the meter never becomes a debate.
the dip
Shade is the honest tax
A chimney shadow at 15:00 shows up here forever. Direction and shading move more money than any hardware upgrade.
Redraw your curve
Direction and shading decide everything. A north balcony never pays back, and we would rather the chart tells you than a checkout page.
3.9years payback
Three rigs that sit on the curve
- RENTERS · strap-mount duo, 800 W, zero holes, moves out when you do
- OWNERS · flush glass set, 850 W, wind-load rated, the one neighbors ask about
- MAXIMIZERS · tilt-frame quad, 1600 W, buys back the low winter sun. check your local watt limit first
