	The assumption of a GSHP installation is that the thousands of tons of soil below contain enough mass to heat a house for many many years. Solar Charging is a process to ensure that it does. This process can be done using the same [[glycol]] (antifreeze) circuit that is already being used by the GSHP. By adding to the existing loop a simple Solar panel on the roof or wall of the house, and providing a temperature activated pump, the panel will send heat deep into the ground throughout the summer months. The ground will not get hot, it may only get warm, but it will be stopped from getting very cold in winter. The efficiency ([[Coefficient of Performance]] - CoP) of the GSHP will be retained throughout the winter, instead of declining as the ground gets colder.
