Roof Photovoltaic Panels
Before you make the jump to a solar power system, there are a few important things to think about. There are many varieties of roof solar panels on the market today, and some may be better than others for you depending on what you're looking for.
One feature that all roof solar panels have in common is that, as a result of their design, the solar cells inside the panels receive as much sunlight exposure for as much of the day as possible. When hit by sunlight, the solar cells will produce DC electricity. It's possible to produce any amount of voltage required by wiring together the correct number of solar cells. The DC electricity is then sent to an inverter, which is in most cases located in the vicinity of the home's electrical panel, where it is then turned into the AC electricity used by appliances in the home. If there is any unused power, it can be sent back to the power grid. The power sent is credited by the power company, and the user's electric meter will actually run in reverse. There are a couple of options for those times at which the roof solar panels aren't generating power (such as at night). One solution is to have batteries, which are charged by the panels during the day and then become the main power source at night.

The inverter can also simply switch the home back over to the power grid once power stops coming from the solar panels. Many homeowners are going with the option of using a battery bank, as this can sometimes completely eliminate the need to buy power from the grid.

It's important to choose the right roof solar panels. Some work more efficiently than others. With the same amount of sunlight exposure, two different roof solar panels can generate vastly different amounts of power. With more efficient solar panels, a system generate the same amount of power with fewer panels, taking up less space and potentially reducing costs.
Another thing to take into consideration is the reliability of your solar panels. For one thing, the durability of the enclosure is key. The enclosures are important because they guard the solar cells from the elements. A poorly made enclosure can allow moisture or even objects to penetrate it, and the solar cells will almost certainly be damaged. Damaged cells will then have to be replaced prematurely. Solar cells themselves can have varying levels of durability.
There are a number of ways to make solar cells, each having its own characteristic benefits. The two main styles of solar cells are monocrystalline cells and polycrystalline cells. The superior of the two in terms of quality is the monocrystalline solar cell. Monocrystalline cells are more efficient and durable. Monocrystalline cells justify the greater cost for these reasons.
