My house is east facing,does that mean I can use a solar thermal system?
To gain maximum efficiency from your solar collectors we recommend that you place your collectors on a South facing roof as they receive the most hours of sunshine during the day. If your roof faces south-east or south-west then the efficiency will be reduced by approximately 10%. Any further deviation from a southerly direction leads to less efficiency. East or West facing roofs may require a number of solar collectors to perform the same job which one south facing panel will do.
