Roof-integrated PV

This 1.6kWp PV array forms part of the roof covering and is fully weatherproof.

It's less vulnerable to wind effects (this installation is on the southern-most point of the Isle of Wight exposed to the worst of Channel weather), looks neat and saves the cost of slates.

The array power rating (1.6kWp) is typical of domestic systems and generates 1200-1500kWh (units) of electricity per annum which can be used within the home or exported to the National Grid for credit.

Note the Solar Hot Water system over the porch with a PV-powered pump.

PV-powered water pump
This small array pumps water from underground to feed cattle in Wales.

The array is mounted over the tank to save space and provide some shade.
A small cabinet houses pump, battery and controller.


Part of a domestic rainwater
collection system to feed toilets.  There are other tanks around the
far corner collecting from the
opposite roof pitch.

Nothing is wasted - overflow from
the toilet collectors then feeds
into the garden water-butts.

Domestic Rainwater Harvesting 01
PV + Thermal

This 2.7kWp PV installation had to be fitted in around existing solar thermal units as well as roof windows.

Panels were chosen for maximum output in the best-fit dimensions.  From a distance everything lines up and appears to be a single array.

Flat-roof PV

This 3.6kWp flat-roof array takes full advantage of an unshaded position (one small tree has yet to be removed in the picture). 

The panels are sloped to minimise visibility to neighbours while maintaining good drainage (for self-cleaning).  These mono-crystalline panels are very responsive to sky light so do not need to be mounted at the usual steep angle.
