Please help a newbie (I am clueless)
This is my first experience with solar. I have been thinking about it for a while. I have read many discussions and articles on the subject, but most of it is above my head. I have no technical knowledge, so please bear with me. I am trying to heat my small green house (10' X 12') with solar. What I have purchased so far is a 15 watt- 12 volt panel, the recomended 4a controler for the panel, a 1000w marine inverter (I figured with the humidity it would be best), a deep cycle battery (not sure of the amps, etc.), and an oil filled electric heater with 600, 900, and 1500 watt settings. Last night was the first night I tried it. Needless to day when I went out this morning the battery was too low to run the heater. What do I need more batteries, another panel? If I need another panel do I need another controler?
