A 15 volt panel is marginal to charge a 12 volt battery, you need something more like 20 volts. A 12 volt battery needs 15 volts with some current to be charged. A 15 volt panel will only put that out with full sunlight, and not with any substantial current. Best is a charge controller (see second reference) that includes a DC-DC converter to adjust the voltage to the optimal value to charge the battery. With this it will be better to put the panels in series and the batteries in parallel so you can charge them both at the same time with one charge controller. . yes, it’s called a charge controller.

To many people are focusing on electrical generation.Solar Heat from the Sun is easier to gather from the sun.It requires no power once installed due to the Fact that heat rises .A multiple of applications of heat collection exist since the 1960's.

So even if the sun is not shining, you are still collecting light for electricity. Solar panels function on day-light.

Depending on your local power company, you may be able to back feed into the grid and draw back out the same amount a few months later.

But they only need sunshine, they don't like the heat, that comes along with the sunshine. So its a trade off, the places that have a lot of sun, also have a lot of heat, and places that do not have a lot of sun are not that hot. But you do need sunlight to run solar panels. There's a lot of tools available which can tell you how much power you are able to generate given your location. Solar panels generate power only during sunshine hours.

The problem is an economic one. Solar panels are expensive and can only produce so many watts per square meter. If you have less sunlight, you'll need more panels to get the same amount of power. Germany has a relatively high latitude, and are reported to make extensive use of solar panels (funny, I spent 2 weeks there last month and saw very few panels). The reason for their use of the panels is that their government offsets the cost of installing them through subsidies. Other governments have similar programs.

However, ironically, solar panels don't like heat, so they work better in the cold. Higher altitudes often have more sunlight, due to less "crud" in the atmosphere, and are often colder than lower altitudes, so you will often get better performance in higher locations. We have solar systems working in every continent in the world, including near both the north and south pole. Solar panels work in sunlight, so obviously the more sunlight, the more power.

Solar thermal collectors use the sun's energy to heat water or another fluid such as oil or antifreeze There is only a one time cost to installing solar panels. The way to get the most for your money is, really to have them installed at the time of the home being built. You have to figure, over-time, how long it will take regarding the cost of the solar panels vs the cost of your energy now. There are two types of devices that collect energy from the sun:
