Oi! I'm building a green building. It has passive/solar/thermal heating, a cistern, etc. No electric. But I need light.
Actually, what I need is 300 watts of light available at the flick of a switch. So: I'll use a solar collector. Connect it to a rechargable battery (or batteries). And run the lights off the batteries. The question: I know that I need 300 watts of light. But I can't figure out how to translate that into LED lingo. What sort of LED bulb/fixture would I need to produce the light that a 100 watt bulb would emit? (The building is three floors, 20 x 40 feet, 12 foot ceilings. A workshop building that I can do car repairs, or tractor repairs in.) I have fluorescent fixtures that produce 100 watts, and three of the 48" fluorescent dual-bulb fixtures would work very well. But I want to do LED lights--no replacement bulbs, etc...) A second question--what size solar collector panel do I need? (OK. I guess that'll depend on latitude, longitude, type of panel, weather. But still, a rough idea would be helpful--I'm in Manchester, Maryland, USA--just outside of Washington D.C.) I told my father-in-law I'd get the answer before dinner. EST. Any helpful suggestions? As always, I am grateful for any advice or info you can offer. Ultimately I'm going to do a book on building a reasonable, affordable, and liveable green home/building. I've got a lot of research ahead of me, it seems...
