Choosing the Best Solar Panel
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 correct orientation to the sun. Some homeowners who might have been interested in solar power have been put off 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 newer solar panels are based on improved solar cell technology and better manufacturing techniques that provide a better solution for all solar power installations. The newer solar cells used in modern panels can offer homeowners better energy production than cells that were available even a few years ago because of several different improvements. The main advantage of the newer solar panels is that they can produce more power from less sunlight. This is good for homeowners since it means that they are more effective for longer portions of the day. Older panels had a limited range of operation during the day and required the sun to hit them directly. During the early morning and and late afternoon these older panels would produce little to no electricity. They also wouldn’t generate power 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 generate more energy and so can help many homeowners justify the cost of installing a solar power system. 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 power they will produce.
These modern panels will also mean fewer solar panels for the average homeowner to provide 100% of the electricity for their house. This also means the solar power system will be less expensive since there will be fewer panels used. For people with limited roof space, this can make a significant difference.

One final advantage that these newer solar panels provide is their longevity. Ten to fifteen years was the average life span of older panels. During that time they would generate their peak output for the first 10 years or so and then slowly degrade to the point of needing replacement. This was due to the gradual failure of the solar cells since as these older solar cells aged, they would start to fail. As the cells began to fail, the panel would produce less and less power. Because these newer solar cells are far more durable, they will last longer than the older versions and also generate more power for longer as well. This makes the investment in solar energy technology an even better choice for the homeowner as they will enjoy the benefits of solar electricity for many more years. A great way to save on the cost of solar panels is by building your own home built solar panel.
Solar panel charge rechargeable battery?
I've been getting really into the whole going green aspect lately and am wondering a simple question, if I hook up a solar panel positive to positive, negative to negative with an AA rechargeable battery, will it charge it? If not what more would I have to add to make it work?
You need to look at voltages and currents to be sure you are not overcharging the battery. You may need a diode between to prevent the battery from discharging through the solar cell when there is no sun. You may need a resistor to limit the current, depending on the voltage and current rating on the solar cell. And you have to monitor the state of charge on the battery to avoid overcharging.
It's more complicated than you think. if you email me the specs on the cells, I may be able to help.
