    This dude built a 1000 watt solar power station.
    I never heard of lights themselves being solar powered.
  3. Yeah It's an interesting topic. I'm actually in the very early stages of planning for Solar Panels. But so much information gonna spend the winter to figure out the best route. Would be interested in others experience and what not.
  4. I figur start up on a solar system would be quite expensive but will pay itself off fast, imagine running a heater fans vent and lights off sun power add the rain and snow catches and your def saving money
  5. If you plan on growing all the time then it will definitely pay for itself eventually.
  6. My plan is to build/buy a good greenhouse that I can grow in all year I imagine it would be the best way to do it, atleast looking at the long run
  7. My whole home is on solar (7200 Watt Outback system with 12 panels and 16 6 volt batteries).   The big challenge you will have is generating heat after the sun goes down.
    If you intend to power your greenhouse after the sun goes down, you'll need a pretty serious battery system.   The lights draw a bit, but any kind of heater draws a TON.  You have to make sure that your battery capacity is enough to store all the energy you need overnight.
    Also - most "home made" systems are 12 volt systems.  Those unfortunately do not generate the type of amperage you need to power anything more than 12 volt lights, which grow lights are not.  You'll need an inverter to convert that power to 110VAC, and with 12 volt systems there is a lot of waste in the conversion.
    If you have the money, look into 24 or 48 volt systems.   Your inverter will have a much easier time stepping that up to 110.  
    If you want to do it on the super cheap and you aren't worried about the nighttime, you can get some used 12 Volt panels,  a cheap 12 volt inverter from an auto parts store and plug your lights into that.
