Hi John Instead of spending money on something that it might not work, you better buy a kit which will include the solar panel, the solar battery and the inverter. You also have to know the wattage you're going to need and depending onto that you can dimension your system. You can get a 85Ah Deep Cycle Battery for example, a 80-100 Watts solar panel, a 300W inverter and a 12V charge controller. All these shouldn't cost more than £600. A system like that can give you about 400W per day (in summer time) and you can power up all your lighting in the house if you change all to LED. Enjoy, Cornelius Cretu
