Solar Panel Degradation

Three part survey — please only honest answers?
Yes or no, why or why not. Thanks to all.
1. Are you concerned about depleting the planet of fossil fuels and the connected problems of pollution, environmental degradation, resource wars, etc?
2. Is switching to a renewable source of power for your home in your plans within the next 5 years?
3. Would you switch to Solar Electric Panels (PV panels) if you didn’t have to pay any more than what you now pay for electricity? (no investment, installation or maintenance cost)
1. yes
2.No. because we already did it 3 years ago. Husband is at this moment working on a new wind generator design.
3. I currently pay nothing, would be happy to install more panels if you will pay me to install them!
Methinks your questions did not cover the situation of existing solar users!
Further comment : our system only just works for us, with minimal household electricity use and living in sunny South Australia. In winter we need to boost power with a petrol generator maybe a couple of times a week.(Not environmentally friendly I know, but better than using candles for lighting!) We use gas for water heating, for the fridge and all cooking, electricity runs lights, TV, computer. Heating is wood stove, the wood comes from our own property, which is big enough to provide enough to keep us in comfort, while still growing more trees and slowly revegetating. In a cloudier/colder/higher latitude area there would be little benefit in winter to a householder even if the house was plastered with panels. In summer it would work for most people. A good system is to have panels, but remain linked to mains for emergency backup, and get refunded by the power company for the power you put back into the system.
