Energy from the sun
Our house uses a number of different technologies to harness energy from the sun. Three are pictured above. The newest and most expensive of these was just hooked up to the grid today, providing 11.4 kWh for the internet dawlders of Australia. So long as I don't goof around on the computer all night, that should cover our home usage and then some. The Hills Hoist also efficiently utilized solar energy by drying three loads of washing. The seedlings in the pots on the black rack have yet to use sunlight to sequester atmospheric carbon dioxide in the form of tomatoes, but we are hopeful for the future.
Can I be rude, and ask how much a solar set up like this cost (roughly), with and without rebates??
ReplyDeleteA Hills Hoist generally costs between 500 and 700 dollars:

The photovoltaics, inverter, etc. were about 6.5 K all up, down from a list price of about 14.3 K. $1500 of the savings was bargaining and discounts, the rest was government subsidies.
ReplyDeleteYou missed counting the window. Light and heat 100% free of charge.
