STEP 2: THE CELLS PRODUCE ELECTRICAL CURRENT.

Now that you know the basics about solar energy, you can marvel at how today’s photovoltaic technology can capture the vast power of the sun to operate a home. It may not be rocket science—but it definitely is human ingenuity at its best.

Each individual panel is constructed of a layer of silicon cells, a metal frame, a glass casing surrounded by a special film, and wiring. For maximum effect, the panels are grouped together into “arrays” (an ordered series) and placed on rooftops or in large outdoor spaces. The solar cells, whi...

Have you ever looked at the solar panels on roofs and wondered exactly what they do, and how? Well, those hi-tech expanses of shimmering glass are actually just one component in a complex network that harnesses the sun’s renewable energy to deliver electricity to the home within.

Once the solar energy has been converted from DC to AC electricity, it runs through your electrical panel and is distributed within the home to power your appliances. It works exactly the same way as the electrical power generated through the grid by your electric utility company, so nothing with...

You now have solar panels working efficiently to transform sunlight into electricity, but the electricity generated is called direct current (or DC) electricity, which is not the type of electricity that powers most homes, which is alternating current (or AC) electricity. Fortunately, DC electric...
