How Do You Build A Home Solar Power Thingie To Plug Stuff Into…?
An electric kettle is a high power unit, so needs a big solar panel and a stack of batteries. These are going to cost a bundle of cash. A great deal depends where you are located – you need a good position where you can mount the panel facing south. You will need solar panels, connected to a charge controller, connected to a deep discharge or leisure battery, connected to an iinverter. The further North you are, the llarger the panel you will need. For greater electrical loads, you will need larger batteries and inverters. In the UK, I guess that a solar panel, plus battery plus and inverter to run the equipment you describe will cost over £2000.
