Solar power systems can provide all of the electrical needs for your home as long as you have adequate roof space and your home has the proper orientation to the sun. Some homeowners who might have been interested in solar power have been discouraged because they did not meet one or the other of these requirements. The result would have been solar panels that didn’t produce enough energy to justify installation costs. Some hope has been given to these homeowners in recent years by the increased efficiency and tolerance of sunlight angles of modern solar panels. One common application is with the use of 12 volt batteries and charge controller coupled with a solar panel to make a 12v solar charger.
These modern solar panels are better than those in the past because of improved technology and more advanced manufacturing techniques. Because of several different improvements, the solar cells in these newer solar panels offer homeowners better power generation than ones that were available just a few years ago. Their main advantage is that they can generate more power from less sunlight than older cells. This means that they can be effective at generating electricity for longer periods of the day.Because of this, they can be used to produce electricity for more hours per day. The number of hours per day the older panels could be used was more limited because they required the sun to hit them more directly. During the early morning and and late afternoon these older panels would produce little to no energy. They also wouldn’t generate energy consistently on days with minor amounts of coulds, even if the sun could shine through them. In all levels of sunlight these newer panels will produce more power and so can help many homeowners justify the cost of installing a solar power system. It is also good news for homes that have a less than perfect alignment to the sun, since it may allow them to produce enough electricity to justify the installation costs.
These newer solar panels will also allow the average homeowner to entirely eliminate their electric bill with fewer panels. The cost for the system will also be less because fewer panels will be used. This can make a real different for people with limited roof space.

Longevity is the last advantage to the newer solar panels. Ten to fifteen years was the average life span of older panels. During that time they would produce their peak output for the first 10 years or so and then slowly degrade to the point of needing replacement. The solar panels would start to slowly fail as one by one the solar cells failed. As the cells began to fail, the panel would produce less and less energy. The newer solar cells are more durable and will produce more energy as well as lasting longer. This makes the investment in solar power technology an even better choice for the homeowner as they will enjoy the benefits of solar electricity for many more years. Many people save a lot of money on the cost of a solar installation by making their own home built solar panel.
