thought about a swamp cooler but have a $400 AC i hate to waste. If I could build a solar system for $1000-1500 bucks I'd be better off. I do like to idea of radiant barrier but we use the rooftop all the time. any ideas on which components to buy? i hear mercado Libre as online source is...

We'll be moving to Mexico soon and the property we are interested in is Mountaintop with Utility grid power several kilometers away. I'm very impressed with Will's knowledge however the topic I am wondering about is not covered. Wind Power might be an option for me since the wind blows at 10+...

Its sliding but after 900kwh its about .50

Thanks. There are Diy solar stores here. I just found one. Running the math, unless i build a rig without using a battery, im better off paying the high elec rate for the 2 months i need the AC. Lokking at a $3000 investment not knowing if we’ll stay here permanently. Higher in mountains is an...

I just spoke to a solar dealer here Queretaro who quoted me JA Solar 410W: $220 USD or CanadianSolar 545W: $320 USD. IT looks lkke the batteries arre whats expensive. If I'm only using the AC 6h/day, and we are 100% sun from like 8-6pm, di I even need a battery? I think the MPPT will just...

good point about higher amps on DC. Your point about turbulence is also good..There is in fact some present I could go up to 16 panels if they are 1m wide. I'm going to try to price those ERDM panels made nearby the site. Maybe purchase a wind Station o put up on a pole before deciding. want...

Can copper bus bars be made from flattening 3/4" copper tubing (the kind for house plumbing). I'm trying to do the same thing as Absentrush

I agree with 99% of what you say here. We here in the U.S. want the cheapest anything. Dispose of everything when it is no longer useful/in fashion (or we get too fat to wear it). CEO's get richer while landfills and oceans acquire more crap. All the while, we complain about the Mexcican Drug...

we have moved to Central Mexico and need to power an 8000BTU window AC which draws 880 watts. I'd like to run it 6 hr/day. We have TOTAL sun and it rarely rains. The flat roof is completely sun-drenched. Should I build a custom rig or off the shelf? at $300/month, I'm ready to revert to solar...
