A first look at what
HoneyWatt can do.
Explore a roof layout and an indicative solar estimate. Enter a site address and electricity bill, or draw a roof to examine system size, yield and economics. This public preview introduces HoneyWatt’s solar design workflow; modelled results still need a site survey and engineer review.
Need professional project engineering? Continue in HoneyWatt →No auto-match? Zoom to your roof and click each corner to trace the outline, then use “Estimate from drawn roof”.
