The design
Why it was
built this way.
Designed around the roof windows. The south-facing slope already had roof windows and a chimney where a standard block of panels would go. Instead of fitting fewer panels or giving up on the slope, the eight panels are laid out in portrait around them, using the space that's left.
Two inputs, one inverter. The layout is split across the inverter's two solar inputs, so each section of the array is managed separately.
A good roof once the layout works. The roof faces 15° off south at a 23° pitch, and the shading assessment found almost no shade (a shading factor of 0.99 in the MCS calculation).
Sized to the household. The design was based on the home using around 3,765kWh a year. The 5.76kWh battery stores daytime surplus for the evening, and a new sub-board was fitted for the solar and battery circuits.
Plenty of Bath roofs have windows, chimneys or dormers in the way. They usually still work; the layout just has to be designed for the roof, not the other way round. Wondering what yours would cost? See my price in 2 minutes →
