Visible sunlight can be converted into renewable electrical energy through the use of solar panels. These can often be confused with solar collectors that are used to heat water. There are also some systems designed for heating air. These are not the Photovoltaic cells that form the photovoltaic modules used in residential solar energy systems. A significant portion of the costs associated with solar panels comes from expensive photoactive materials and energy intensive processes.

It has recently been discovered that the inorganic components used in the manufacturing of solar panels can be replaced by polymers with semi-conducting abilities. These polymers are capable of achieving high power conversions efficiencies and they are inexpensive to produce using a synthesized solution in a roll-to-roll process. Conjugated polymers are dispersed in various manners onto substances used to develop laminates that can be fashioned into low cost electronics and photovoltaic components.

The processes are being developed that enable polymer based solar cells to reach power conversion efficiencies of five percent. This will bring the cost of polymer based PV to a level that can compete with the present grid based electricity systems. Researchers in the field hope to develop material systems that can reach power conversion efficiencies above the ten percent level further lowering the cost of solar panels.

What is even better than future progress is the fact that you can make your own solar panels from easy to obtain materials at a reasonable expense. All things considered, you can build your own system for less than two-hundred U.S. dollars. A Photovoltaic system with solar charge controllers can reduce your electricity costs by as much as eighty percent. Although conserving energy whenever possible is still an important part of reducing your energy costs, you should incorporate any method available to build energy efficiency into your home prior to incorporating a residential solar panel system into your plans. Many people are not aware that even though the computer, TV or any other electricity using piece of equipment in their house is switched off, they are still using power. The only way that these items are not using any power at all, is if it is switched off at the power point itself.

Photovoltaic cells (PV) come in many types and sizes today. They will vary in length, width and thickness. Usually around two inches thick, they can weigh around thirty pounds or less. Some PV panels are as large as five feet by three feet and can be rather cumbersome. Other types are made from flexible materials that can actually be rolled up.

The industry standards are the framed solar panels. These are currently the best option for lowering the cost of solar panels. The number of panels needed to meet your needs depends on the amount of electricity necessary to supply the demand for power created by your household. The number of day light hours that your system is able to function at maximum output will influence this also. Used PV cells are available on e-bay for prices ranging from around fifty to one hundred U.S. dollars.

A charge controller, charge regulator or battery regulator should be used for all but the smallest solar as they limit the rate at which electric current is added to or drawn from electric batteries. It prevents overcharging and depending on the complexity, may also prevent against overvoltage, which can reduce battery performance or lifespan, and may even pose a safety risk. It may also prevent completely draining or "deep discharging" a battery, or perform controlled discharges, depending on the battery technology, to protect battery life.

Rowland Kubale is a boat owner interested in Solar Energy, it's production and applications. Find out more about how to build your own Solar Panels for about $200 or so as against $2000+ for an off the shelf solar panel.
