What to look for

Consider the following when choosing a solar panel system:

• A system, not just panels

  As well as solar panels, you will need a solar hot water tank, new lengths of pipework and controls. These should be sized and installed by a CANSIA-approved professional.

• Your purpose

  The best configuration will depend on whether you are using the system for domestic hot water only, for domestic hot water plus space heating, or for a swimming pool. Again, consult a CANSIA-approved professional.

• Durability

  Coatings and seals should be guaranteed for at least 25 years for normal circumstances.

• Government Grants

  A wide range of government grants are available, depending on the building type and application. A professional installer may be aware of other subsidies in addition to those mentioned here. You are also advised to read the conditions carefully for grant or rebate schemes - and note that, while most good projects can be funded this way, not all can.

  Homeowners can get a fixed rebate of $1500 through a combination of provincial and federal programmes for adding panels to an existing home. New homes built to EnergyStar or R2000 standards can claim a $1000 grant for solar panels. For a limited time there is an additional subsidy opportunity through the NRC, which is worth another $1300 to $1700. Businesses, public institutions and non-profit organisations can typically get 25% of the pre-tax price paid by the provincial government (SHIFT) and another 25% by the federal government (ecoEnergy for Renewable Heat).
