Solar Cell Panel
As fuel costs continue to rise, many consumers are looking for alternative ways to generate electricity for their homes 
and reduce their energy bills each month. Solar power systems represent a great solution and can help homeowners lower the amount of power they buy each month from their local utility by augmenting their power with free electricity from sunshine. These modern solar power systems have become very efficient in the amount of power that they can generate from the sun and today represent a major improvement over systems available even a few years ago.
At the heart of any solar cell panel is the solar cell. These solar cells are the basis for the system and have the ability to create an electrical current from sunshine directly. A solar cell panel is basically created from a collection of solar cells that are wired together to produce electricity. Individually, these solar cells generate a small amount of current, but when they are combined together in a solar cell panel the current they generate can be quite large. Through improvements in these solar cells, consumers are now able to generate more power than ever before from sunlight.

These newer cells have efficiencies of close to 20% and even do a better job than older cells in generating electricity from less intense sunlight. Older cells had a minimum threshold for electrical production and would stop producing a current at all if the sunlight that hit its surface was below this threshold. This meant that at dawn, dusk and cloudy days these older cells might not produce any current at all, even though the sun was shining. The newer solar cells have a very low threshold, which means that they will not only produce more current from a given amount of sunshine than older cells, they will do it for more of a given day.
This single improvement means that many consumers that could not use solar cell panel systems to power their homes in years past because of the orientation of their homes, can now use these modern systems and generate large amounts of power as well.
Another recent innovation in the solar cell panel is the inclusion of a micro-inverter. In older systems the panels would all produce DC current that could then be sent to a large inverter that serviced all of the panels in a given system. This inverter would convert the DC into AC current for use in the home. The challenge with this was that there was a loss in current because of the long wires needed to connect the solar cell panel on the roof to the inverter in the basement. Some newer solar panels solve this problem by including a single mini-inverter in each of the solar panels themselves. This means that each individual solar cell panel can do its own conversion fro DC current to AC current and eliminate the current lost in older systems.
This type of system is also easier to wire and less expensive overall. And even though these panels are more expensive than older panels, by eliminating the cost of a larger inverter, and considering their much higher output current, they represent a better value for consumers and an overall lower cost of installation as well. All of these improvements make the current solar cell panel systems a great alternative for homeowners to buying power from their local power utility.
