There are a few things to think about before installing a solar power system.  With such a variety of roof solar panels on the market, it’s worthwhile to consider what some of these options have to offer.

All roof solar panels are built in such a way that the solar cells inside get as much exposure to sunlight as possible.  Solar cells, when hit by sunlight, produce DC electricity.  The correct number of solar cells, once wired together, can produce any amount of voltage.  After it’s generated, the DC electricity is sent to an inverter, which then converts it to AC electricity so that it’s able to be used in the home.  Any excess power can be sent to the power grid.  This turns back the user’s power meter correspondingly, and the power company credits the power produced.  Roof solar panels don’t generate electricity when the sun isn’t shining; there are a couple of options for dealing with this.  One solution is to have batteries, which are powered by the system throughout the day and then take over as 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.  The battery bank option does come with some initial cost, but it’s a more affordable solution in the long run.

It’s important to choose the right roof solar panels.  Although any solar panel will produce electricity, some produce more efficiently than others.  With the same amount of sunlight exposure, two different roof solar panels can produce completely different amounts of power.  A system with efficient solar panels will be able to generate the same amount of power with fewer panels.

Durability is also important.  For one thing, the durability of the enclosure is crucial.  The solar cells inside the enclosures are very fragile and require protection from the elements.  Enclosures that aren’t well made will often allow moisture and objects through.  If cells are damaged repeatedly, the cost of replacing them can quickly add up.  The durability of the solar cells themselves is also important.

Solar cells differ in how they’re built and, as a result, the benefits they offer.  The two main styles of solar cells are monocrystalline cells and polycrystalline cells.  Of these two, the better one in terms of quality is the monocrystalline solar cell.  They output more current than polycrystalline cells, and tend to last longer.  For these reasons, monocrystalline cells are worth their slightly higher cost.  For further information about solar cells, please visit Solar Cell Efficiency.
