Max Lewis (‘Shedding more light on the Greens' solar deal' The Weekend Sun, February 28) is sadly misinformed about solar feed-in tariffs and the Green Party's energy policy.

Firstly, to quote Mr Lewis; '…the grid company will buy it at 0.6c/unit…” – this is incorrect. Tariffs differ from company to company; our provider pays 25 cents per kWh for the first 5 kWh exported each day, reducing to 10c per kWh thereafter - far more than .6 of a cent per unit. Furthermore, fair feed-in tariffs are an integral part of green energy policy; storage will not be an issue if exported power is fairly recompensed.

Consumption can easily be planned around generation, for example: Do the washing in the morning, install a simple timer to turn the water heater on in the early afternoon, cook food in the late afternoon and reheat for the evening meal. Lost opportunity costs? Our system cost just over $14,000 (and photovoltaic system prices continue to drop).

We do not avoid using imported electricity at night; even so, return on our investment is considerably more than that of 'money in the bank”.

It's interesting that any innovative and forward-thinking policy providing such an obvious benefit to ordinary people is labelled 'election bribery”.

Domestic photovoltaic systems may not suit every household, nor provide for all electricity needs, nevertheless they are a vital part of a modern and sustainable renewable electricity infrastructure and provide cheaper, cleaner power to ordinary people.

Oh, and one more point. The sun doesn't 'lose energy” at night – it's still there, bless it, blazing away happily on the other side of the planet.
