Guide To Selecting Solar Panels

There are several factors to consider when choosing a solar panel for the solar power system, including the :

1. capacity of solar panels

The capacity of solar panels in Watts directly affects the price, the price of solar panels are usually comparable to in dollars per Watt.

Watt is associated with the output of each panel, which means that a solar panel of 100 Watts under ideal conditions would produce 100 Watts of electricity per hour and 200 Watt panel would generate 200 watts per hour. Therefore expect to pay double the price for 200 Watt panel, compared to 100 Watt panel
.

The capacity of a solar panel also affects the physical size of the solar panel, panel 200 Watt mean will be greater than the size of a panel of 100 Watts.

Types of solar cells that are used in the production of also determines the size of the solar panel. as consideration is that your system as a whole has had enough power to the power needs of the whole insufficient your equipment, and whether these solar panels have been physically fit in pairs and placed in an area where we will put it up.

2. the cost of

The cost needed for solar panel is usually determined by capacity (in watts), physical size, brand, durability/age use (length of warranty) and certification of solar panels. Selecting solar panels based on price alone is not wise, since it may not match the area where we are going to put it up, because we're going to wear on its own may not require the certification that is required to qualify for a Government project.

3. the Durability/Longevity/Warranty

Durability or age wear of a solar panel is a very important thing to consider. First, if the solar panels only have warranty for 10 years and is used in the system which we expect to generate enough power within the next 10 years.

If the panels to be used in systems which is important so we don't have to take the risk of installing solar panels that are age-of-low. A reliable solar panels will normally have a warranty period for 25 years.

4. the efficiency of solar panels

There is much debate about the efficiency in solar panels, solar panel how effective in converting sunlight into electricity, but a key point to remember is that solar panels with a capacity of 100 Watts will produce 100 Watts; Apart from ranking efficiency.

SOLAR PANELS WHICH ARE SUITABLE

There are 3 main types of solar cells.

1. Mono-crystalline silicon

This type is the most efficient and produces the smallest solar cells, and therefore the panel size is the smallest.

2. Poly-crystalline (or multi crystalline) Silicon

the next type of cells that produce the most efficient, but the equivalent wattage panels greater than monocrystalline.

3. Amorphous Silicon (thin film)

Use a bit of silicone and also produces efficient solar cells. This means thin film systems take broader extents of the two previous, but has the advantage of the price panel and can be used on curved or irregular surfaces of this type is not suitable for solid panel.

Solar panels suitability

Mono-crystalline and multi crystals works very well in conditions of cold temperatures and bright, whereas the amorphous (thin film) Silicon will be more efficient at higher temperatures.

We usually recommend monocrystalline or multi-Crystal for this type of roof with no connections, and amorphous panels for roofs with a partial form.

Regardless of the technology that is currently in use, a solar panel that is placed in a shady place will produce only a fraction of its capacity, so the shade-tolerance feature advertised may be a little misleading.
