Alright, but do you know chich one would be better? forestry or MFR?
@Dark0, no-maintenance is not subjective. Lava can run out, making it not no-maintenance.
Yes, before we go further, which pack/mods the OP are using would be useful.To be fair he asked for a no maintenance setup. low maintenance =/= no maintenance. There are a couple I could suggest. Which one easier/better would depend on what mods you have installed.
Thats not the point, we need a reference to what kind of mod enviromend you are running. Are you running vanilla MC plus 1-2 mods or what? FTB pack like DW20, ultimate, unleashed? Custom pack? It would be a monumental waste of our time to list every single solutions for every single combination of mods for all the different versions of mods/modpacks.Mods installed are not an obstacle, I'll install the mods if I'm missing any.
As the title reads, I'm looking for suggesting as to how to get MJ from either solar sources or other no-maintenance sources.
The purpose of this is to power a lot of quarries and later whatever else.
I suggest you check out that new(to FTB) mod Gas Craft. Hydrogen is easy to get with it, and is energy free(technically, assuming your water source is free and can supply a item from a farm for free). Add water and Algae to a Photobioreactor module on a modular socket and you get hydrogen. The reaction costs only sunlight and algae since water is easy to make infinite and free.ICx - Windmills, Solar panels (compact versions of both).
Mekanism - Electrolytic Separators + Hydrogen generators (needs a jump start, self sustaining after)
Atomic Science - Chemical engines + Steam Funnel + Rotary Turbine (needs a jump start, but self sustaining after)
Treefarms, Boiler setups, hell, get a pig spawner from TForest that is linked to a MFR grinder, that sends the porkchops to a Caliometric burner which powers the grinder.
There's a lot of options, just depends on what you're using.
