I could afford 3 10 room mansions on the Gold Coast next week if I wasn't on the bad tenants list. I don't see the point in upgrading unless it's substantial. I have 3 graphics artists on payroll at the moment. I'm ordering 10 15W amorphous panels today ($1000) to bring me up to 300W total, although the Mono's barely work in winter due to the low slope on the shed roof. And 300AH in batteries ($1400) and not sure what inverter, might get a $2000 inverter charger computer controlled system so I know how to expand later. It's just open plan living, septic loo in the corner, 12V shower on a mat, spray the place with a huge dose of cochroach surface spray once a month! No point getting a $10K caravan now, take me a couple months to save $50K, may as well get a mortgage. Herc
