PV Systems Today

That is the reason why solar cells are such an intriguing technology. They are by no means perfect yet, but every year they are becoming gradually more efficient and less expensive to provide. Whether you use them in a grid-tie system or an off-grid one they're going to provide clean, efficient energy for many years to come. Maybe most impressively nonetheless the typical solar installation includes no moving parts. That implies there's little to break down or wear out through repeated motion.

An ordinary photovoltaic system incorporates the panels, often referred to as solar arrays, solar inverters and solar battery chargers. The panels create electrical energy when struck by sunlight, which is then fed to the batteries. The batteries are where the power is drawn from when you turn on a light, the microwave, or another appliance. They store the energy for use so that even in the night, or when it is overcast, you will still have a constant supply of power. These systems can be installed in homes, cabins, and even RV solar energy panels or ship kits for solar energy on-the-go. It is simple to install them, but you'll need the help of a skilled pro for some technical details.

In grid tied systems, rather than battery backup, the panels are tied to the present electricity network. When you are creating more power than you use, the surplus is fed back to the grid and the power company buys it. When you use more power than you create, the power company supplies the difference. With a grid tie system it is reasonably common for the power company to send you a check each month rather than a bill!

Future Probabilities

But we are just starting to tap the potential of photovoltaic power in solar power systems today. Current research into multi-junction solar cells guarantees to increase the bandwidth of serviceable light that panels convert into electricity. Each substance has a particular frequency of solar lighting which it can convert ; by layering 1 or 2 different substances over one another a multi junction cell can harvest just about the whole observable range of light, rather than only one or two wavelengths.

Another exciting invention involves thin film technology. Now, thin film panels can be made which employ a lot less silicon than regular crystalline panels. But scientists are developing far more parsimonious techniques of manufacture, and experimenting in silicon suspension strategies too. The next great application of thin film in solar electricity systems might be solar blinds that harness the daylight that hits your windows. Further down the road, we may see paints which are capable of becoming solar generators by creating an electric charge. Imagine a world in which the exterior of buildings and even autos are put to work creating power! That capability is years from a fact, but the potential is there.
