Domestic PV systems are still the most active market as people become more comfortable with the technology.
People are also seeing endless increases in energy tariffs and solar as a way to stop this. Also, with the prevailing government incentive scheme, the cost of a system is not out of reach. Not all electricity providers offer solar-friendly tariffs so it is best to check and compare the following items prior to entering into an electricity trading agreement.
Questions to ask your provider include:
- What price will they pay you for your electricity (in cents per kWh)?
- What is the cost of the electricity you purchase from them (in cents per kWh) and will you lose your off-peak rates?
- What will be the form of payment for electricity you produce?
- Will your metering register your net or gross output?
- Are there any penalty clauses (termination costs) or other administration fees?
- What are the billing/payment periods?
- Do you need to organise all the necessary metering changes and what are the associated costs?
- How will excess energy be calculated (e.g. instantaneously, daily or quarterly)?
