Photovoltaic solar panels
Renewable energy

Solar heating and energy generation

...to get 20 to 25 years from the system. Photovoltaic (PV) solar panels Without getting overly technical, Photovoltaic solar panels essentially convert the sun’s rays into electricity. Systems can be large enough to provide your entire home power needs, and be either stored in batteries or fed back into the power g...

Thermal batteries: how to passively store heat

...to make the 1 kg block go from 20°C to 21°C. To make it go from 21°C to 22°C, you will also need 2.5 kJ (i.e. the same amount of energy). Paraffin melts at approximately 37°C. If it drops to 36°C, you will again only need 2.5 kJ to bring it back to 37°C, but you would need 210 kJ (84 times as much) to go from 37 to 3...

How can I put a Tiny House on my property legally in the USA ?

...to power a Tiny Home, the cost of setting up a solar array is usually far too high and that it would take too long to recoup the investment. Tiny houses with solar panels are more commonly seen with homes where there is no access to grid power; they also tend to include home batteries or at least some kind of power sto...

Are Small Wind Turbines for Homes Any Good?
Wind power

Is this the safest and most powerful small home wind turbine yet?

...to pay it off, then you’re better off with the solar panels this thing is trying to compete with. It’s important to put tangible figures to these things if they are to take hold in the market. It’s great to see innovators stepping up with new ideas, but they won't all be game changers. In our opinion, while this one ...

Solar Electricity Generation & Storage with no Batteries, Azelio
Renewable energy

Azelio Solar solutions combine electricity generation & storage without Batteries

...solar panels Standard photovoltaic panels absorb photons from the sun, which causes a reaction with electrons in the solar cells, and converts that action into electricity. But one of the drawbacks is that this only happens while it's sunny. To provide a constant power supply requires enough solar panels to account f...

Which is the Best Type of Home Energy Generation for Green Homes?

...to illustrate that there is not one right answer to the question of 'to be or not to be' someone with photovoltaic solar panels, your own wind turbine, solar heated floors , bike generator , or even a water-wheel! Solar heating - passive & active energy Passive solar heating refers to designing a home to collect he...

...to a lost opportunity to collect heat, whereas excess power generated by PV panels can be fed back into the power grid. Thermal solar systems do not lend themselves well to solar trackers (panels that follow the sun to maximize efficiency) which is not uncommon to see with PV solar systems. On average, a photovolta...

...to above, I am in the middle of putting together a system to use up much of this excess electric power for space heating in the winter and domestic hot water heating in the summer. If we were able to put all of this excess capacity to use, that would mean our total needs from propane would drop to a projected 9,074 kWh...
