Absolutely. Even though the cost of going solar is at historic low, greater efficiency should always be the starting point. From an architectural perspective, designs incorporating super insulation, thermal mass and passive solar not only save energy, but are more comfortable to live in and can be extraordinarily ...

I agree that lead acid is still a viable option for home energy storage. Why? Mature technology. We know what to expect. Less expensive than other technologies Long service life. My first set of Rolls flooded lead acid batteries lasted 17 years. Second set likely will last even longer. Near 100% ...

Hard to beat the price and should be fine. Sometimes you need more power than you think. Peak usage is going to be in the morning and evening, as the team will be in the field all day digging. One thing to consider is how the panels are mounted. It looks like the kit has Z brackets to mount them flat ...

I'm wondering if anyone is aware of a system for charging an electric vehicle for us off grid folks? Obviously I could just plug it in to a 120V AC outlet when we have adequate sun but that seems like a pretty inefficient and labor intensive way to go about it. I'm thinking of a something more along ...

My understanding is that despite efforts to minimize losses (e.g., air cushion bearings) it still takes a lot of energy to keep a massive flywheel spinning - and to spin it back up after being depleted. As such, this technology is more appropriate for smoothing loads in large scale systems with batteries ...
