A long as your home has adequate roof space and the correct orientation to the sun, a solar power system could provide all of the electricity for your home. Because of a problem with one or the other of these requirements, many homeowners who would otherwise be interested in solar power have not been able to take advantage of the technology. This meant that the solar panels may not have generated enough electricity to justify the cost of installation. Improvements in solar panel technology in recent years should give hope to these homeowners, as modern panels are more efficient than older versions and are also more tolerant of sunlight that is hitting them at a steeper angle. If you take the solar panel and connect it to a 12 volt battery and charge controller, you have the most common application of a 12v solar charger.

The improved technology and more advanced manufacturing techniques used today provide better panels for all types of solar power installations. The solar cells used in these solar panels have improved in several ways and offer consumers better power generation than solar cells available even a few years ago. Being able to generate more electricity from less sunlight is the biggest advantage of these newer solar cells. This means that they can be effective at producing electricity for longer periods of the day.Because of this, they can be used to produce electricity for more hours per day. Older panels had a limited range of operation during the day and needed the sun to hit them directly. When the sun was hitting the panel at a steeper angle, these panels would generate little to no power, like in the early morning or late afternoon. They were also intermittent on cloudy or rainy days since even though the sun was shining, it may not have been bright enough for the panels to produce power. The newer panels will generate more electricity for a solar power system in all levels of sunlight and this can help many homeowners to justify a solar power system for their homes. They can also allow people with homes that have less than perfect alignment with the sun to justify a solar installation because of the additional energy they will generate.

These modern panels will also mean fewer solar panels for the average homeowner to provide 100% of the power for their house. Because there are fewer panels used, this will also mean the system is less expensive. For people with limited roof space, this can make a significant difference.

One last advantage that these newer solar panels provide is their longevity. Ten to fifteen years was the average life span of older panels. The panels would generate peak power for about ten years and then degrade over time. This was due to the gradual failure of the solar cells since as these older solar cells aged, they would start to fail. Since the solar panel was a collection of many of these cells it would still produce electricity, only less. The newer solar cells will last longer and will also generate more energy while they are viable. This means that a homeowner will enjoy their benefits for many more years, and makes their investment in solar energy technology an even better choice. Many people save a lot of money on the cost of a solar installation by making their own home build solar panel.
