When designing a renewable energy system it is vital to first of all find out how much and where energy is being used, then see how this can best be matched from available renewable resources at the site location.

Equipment must then be carefully selected to suit these needs, be compatible and within budget. Any logistics and installation issues must be addressed and then a suitable installer appointed.

Many of our suppliers offer free design tools for installers to help correctly select and configure equipment:
