Instead of a feed-in tarrif, power utilities should provide the capital outlay for solar panels (and therefore own them), with the site owner receiving a small discount on the service charge (not the usage charge).
The feed-in tarrif, at least for those like me who had panels installed years ago, is highly regressive. Those who could afford the 10K+ outlay continue to receive a huge credit, paid for by higher charges to those who can't and subsidised initially by taxes on them (that 10K was after rebates). I am interested in supporting clean energy, not in owning infrastructure in the industry, with the attendant responsibility to maintain it. Keeping ownership with the power generation utilities aligns responsibility with expertise. A service charge discount encourages site owners to make their premises available for cleaner energy production, without dampening incentives to minimise usage - demand is the other side of supply.
