If you’re not sure if different solar generator components will be compatible, you can take a shortcut and get aRenogy 200W Solar Starter Kit. This DIY solar generator kit includes two 100W solar panels, one 30A charge controller, and a solar adaptor kit together with all the cables and ...
A simplistic model of an atom, known as the Rutherford–Bohr model, Bohr model or Bohr diagram has a central nucleus made up of particles called protons and neutrons. The nucleus is surrounded by orbitals containing electrons. In some materials such as metals, electrons are bound loosely to ...
Theangle of light entrychanges when you move the object closer or farther away from the lens. You can see this in the diagram below. The light beams from the pencil point enter the lens at a sharper angle when the pencil is closer to the lens and a more obtuse angle when the pencil ...
And never presume that there will be a bus to get you from A to B, or that the trains will be cheap on the day of travel, because you will be landed with an ugly fare. It is also a fine balance between being stuck with concrete travel plans, but still having some flexibility if ...
How to Make a Solar IPod/iPhone Charger -aka MightyMintyBoost: I wanted a charger for my iPodTouch and the MintyBoost was definitely my first choice. I wanted to take it a bit further and make it not only rechargeable but also solar powered. The other is
How a Photovoltic Cell Works. When photons strike a PV cell, they may be reflected or absorbed, or they may pass right through. Only the absorbed photons generate electricity. When this happens, the energy of the photon is transferred to an electron in an atom of the cell (which is actu...
MPPT extracts a maximum amount of energy from solar panels and converts it to a lower voltage to charge batteries. MPPT employed a buck converter scheme to do the power transfer for its high efficiency. How Buck Converter works This is my 2 cents explanation on Buck Converter based on ideali...
can-sized transformers held up by two utility poles. They regulate the voltage on the line to prevent undervoltage and overvoltage conditions. The regulator bank works to maintain a steady 7,200 volts running through the neighborhood on three wires (with a fourth ground wire lower on the pole...
This diagram shows the basic parts and design of a circuit breaker. HowStuffWorks The power distribution grid delivers electricity from a power plant to your house. Inside your house, the electric charge moves in a large circuit, which is composed of many smaller circuits. One end of the cir...
Animation: How an electrochromic window works: Apply a voltage to the outer contacts (conductors) and lithium ions (shown here as blue circles) move from the innermost electrode to the outermost one (from left to right in this diagram). The window reflects more light and transmits less, caus...
