From photon to power point
What a cell does with light, what the inverter is for, and why a 400-watt panel almost never makes 400 watts. The mechanism, before anything else.

Bifacial Panels: What Is Under the Array Decides
Rear-side generation depends on the surface beneath and on mounting height. Where the gain is real, and where flush roof mounting makes it close to pointless.

Half-Cut Cells: Less Current, Less Loss, Less Shade
Cutting cells halves the current per cell, which cuts resistive loss and changes how shade propagates. Why the module splits into two halves electrically.

How a PV Cell Works: The Junction and the Half-Volt Rule
Understand PV cell physics: doped silicon, the p-n junction, and why each cell yields ~0.5 V. Covers series wiring and temperature effects.
-
How a Solar Inverter Works: DC to AC and Grid Sync
The inverter converts DC from panels to grid-synchronised AC. It tracks the maximum power point, builds a sine wave, and disconnects when the grid fails.

How Rooftop Solar Works: From Cell to Meter
Understand how rooftop solar works: panels, inverters, wiring, and net metering. Learn what affects output and what to check locally.
-
How Solar Panels Produce Electricity
Learn how solar panels convert sunlight into electricity, from photons to AC power, and discover the key factors that affect their energy output.
-
How Solar Panels Work: Photovoltaic Cells Explained
Understand how photovoltaic cells turn sunlight into DC electricity, the role of inverters, and how the system connects to your home. A clear, technical explanation.
-
N-Type vs P-Type Solar Cells: What the Doping Change Means
The doping type of a silicon wafer sets how a cell degrades, how it behaves when hot, and how it responds to light from behind. Here is what changes.
-
Peak Sun Hours: What the Number Actually Measures
Peak sun hours are a unit of energy, not daylight length. How irradiance, insolation and a derate combine to predict what a PV array will produce.
-
Perovskite Solar Cells: How They Work and Why They Degrade
Learn the working principle of perovskite solar cells, their efficiency potential, the stability problem, and how tandem cells stack up.
-
PV System Components: What Each Part Does
Learn what makes up a photovoltaic system: panels, inverter, mounting, isolation, metering. Understand each component's role and failure modes.
-
Solar DC or AC: How Panels Produce and Convert Power
Solar panels produce DC electricity; homes use AC. Learn why conversion is needed, the losses involved, and why both currents are essential in a PV system.
-
Solar Panel Efficiency: What the Datasheet Number Means
Understand what solar panel efficiency measures, why higher efficiency isn't always better, and when it truly matters for your roof.
-
Solar Panel Output: Rated vs. Real-World Production
Understand why a 400W panel rarely produces 400W. Learn about STC, temperature coefficients, and factors that affect real-world output.
-
Solar Panel Recycling: What Happens at End of Life
What a module is made of, which parts have recovery value, and why landfill is still common for reasons of logistics and economics rather than chemistry.

Solar Thermal vs Photovoltaic: How Each Works
Solar thermal collectors heat fluid; photovoltaic cells make electricity. How each converts, stores and protects itself, and why heat pumps now join the comparison.
-
Types of Solar Panels: How They Work and Compare
Learn how monocrystalline, polycrystalline, and thin-film solar panels are made, their efficiency, heat behavior, and where differences matter.
