Solar power and usage

This page covers one of the most significant additions to the house, not just the addition of 4 kWp of solar panels, but also the various systems that are in place to make sure that we make good use of it by automatically switching on load when sufficient solar power is available. Like many UK homes our export is deemed (that is it is assumed that 50% of our generated energy is exported) and thus the marginal cost of using another kWh is zero making energy for self-use free.
