We just want to cover our power bill, not looking to make $$$ selling it back to the electricity provider. With the way everything is going up this is a giant step towards keeping one step ahead. DH is a Vietnam vet and on a full TPI pension. He only gets a pay rise if the CPI goes up which it doesn't always. I'm not complaining, we manage quite well because he also has a super which pays him each fortnight. We also love that Solar energy does no harm to the environment . Will post pics when it is installed.
