How should PV yield on different roofs be compared?
Engineering answer
Compare neighbouring roofs using separate yield simulations for orientation, pitch, seasonal shading and electrical losses. Examine expected annual kWh per installed kWp as well as the hourly production profile. Different module layouts or inverter configurations may be needed even when the roofs are close together.
