Sunlight is the whole point of solar, so understanding shade is one of the most important steps in a good design. A shade analysis maps how shadows move across your roof through the day and across seasons, so panels go where they'll produce best. Even in sunny Los Angeles, roofs deal with shade from trees, chimneys, neighboring buildings, and hillside terrain — and accounting for it up front leads to a smarter layout and realistic expectations, not inflated ones.

What we learn from shade analysis flows directly into design. On a partially shaded roof, microinverters often make sense because each panel operates independently, so shade on one panel has less impact on the rest. On a clean, unshaded roof, a string inverter may be a cost-effective fit. Either way, monitoring later confirms each area performs as the analysis predicted.
A good shade analysis is also honest. Rather than promising a number, it gives a grounded picture of what your roof can produce, which matters under California's net-billing rules (NEM 3.0) where using your own production is central to value. If shade is significant, we'll tell you — and discuss whether trimming, repositioning, or a battery makes sense.
We analyze shading and place panels where they'll produce best — with realistic expectations in writing.

Even sunny Los Angeles roofs often have shade from trees, chimneys, vents, neighboring buildings, or hillside terrain. Shade on part of an array can reduce production, so analyzing it up front leads to a smarter layout and more realistic expectations.
Often yes. Many partially shaded roofs are good candidates with the right design — for example, placing panels in the sunniest zones and choosing panel-level electronics. A shade analysis tells us what your specific roof can realistically produce.
Shade often points toward panel-level options like microinverters, because each panel operates independently and shading on one has less effect on the rest. On unshaded roofs, a string inverter may be a cost-effective fit. The shade analysis informs that choice.
