So, I have converted an old shuttle bus to be a tour bus for my band. So far the 'Caterpillar' as we call her has treated us well and made it through a national tour and a regional tour. Now we are thinking more long term and want to be more self sufficient and sustainable. I am thinking of making a pedal, solar and wind combination system. Here are some questions that I cannot find a clear answer to : FIY I am planning on installing one (maybe two) solar panels on the roof, making a pedal system with old bike parts and a generator, and making a DIY wind turbine. Cost is surely a factor for us musicians on a budget, but we surely do not mind spending extra money on components that will last longer or are less prone to failure. The system would need to be large enough to run a laptop, recording interface, some lighting, a guitar amp and charge some phones - I would possible run the bus's interior lights, a space heater, and rice cooker off of the system if it ends up being mighty enough. And if it ends up being really mighty it would be incredible to have the ability to run a full band set up off of the system (a band usually can run off one 20 amp AC circuit) (In terms of AC circuits - I would be looking to ideally have the power of a standard 15-20 amp circuit - I am still learning how many / what types of batteries, etc would be comparable) **When it comes to charge controllers - are there any particular models / types that would serve the system I have in mind best (one with 3 power sources - solar, wind, pedal)? **When it comes to batteries what is the best and second best options for a system like this / Do any batteries handle different amounts of input power, outputting power, and just overall handle less stable cycles better (as in not always being fully charged before being used, etc)? - lithium ion? Unsealed batteries? Sealed? **Solar Panels - DIY vs buying one - any suggestions to articles, DIY links, etc would be greatly appreciated. - I have found some great resources, but would love to see some more. ** Wind Turbines - any DIY links would be appreciated. Any insight would be so very appreciated. Is it wise to work with 3 power sources or should I think more simply.
