I am in the very beginning of my photovoltaics adventure, so I would appreciate your advice.
I want to have up to 250W of power available at an AC socket with probably total usage of 500 Watt-hours drawn during one day a week. The location is a small shed with a south-facing sloped roof.
The idea is to have a solar panel connected to a solar controller charging a car battery, with an inverter connected to the battery. The usual setup.
- what size of a battery I need and where to buy it?
- what controller would you recommend? I want one that can at least show the battery charge remaining and probably current in/out. Also one that would not burn my shed down.
- can I buy a kit (panel/controller/inverter) in Ireland that is not outrageously overpriced?
- best way to fix a solar panel to a metal corrugated roof?
This is a PV education project for me, so an advice to charge a battery at home would be redundant. Money is not a problem for a reliable system.
