WattSnap
Point your phone at a roof, balcony, garden or campervan and see what a solar panel there could generate — and what it's worth.
Visit projectSolar shouldn't be a guessing game. WattSnap turns your phone into a sunlight value meter.
Point it at a spot — a balcony, a roof, a garden, a campervan — and get an estimate of how much electricity, and money, a panel there could generate. Less a solar calculator, more a way to see what your sunlight is worth before you spend anything on it.
