Considering about using solar energy as a way of greening your life and lightening your environmental footprint? When picking panels for your solar power system, you'll find numerous elements worth thinking about. Get extra information and facts about Dallas Solar Energy
Cost
The cost of a solar panel is determined in portion by the size (in Watts), the physical size, the brand, the durability / longevity (or warranty period) and any certifications the solar panel may well have. Deciding upon a solar panel on price tag alone is just not wise, because it may not fit the region you want to install it, might not possess the essential certifications to qualify for government rebates, or might not possess the warranty needed for economic payback from the power made.
Durability / Longevity / Warranty
The durability or longevity of a solar panel is significant for any number of causes. Firstly, in the event the solar panel only has a 10 year warranty and it really is applied within a grid connect system you'd anticipate the solar panel to generate sufficient power to spend for itself within 10 years.
Also, in the event the panel is to be applied in a important system you should not risk installing solar panels that aren't as robust because the other folks. Reliable solar panels will have warranty a period of 25 years.
Solar Panel Size and Wattage
The size with the solar panel in Watts will directly affect the price tag, as solar panels are usually priced (and compared) in dollars per Watt.
Watts are related to the output of each panel; which means a 100 Watt panel below best circumstances will create one hundred Watts of electricity every hour along with a 200 Watt panel will produce 200 Watts each and every hour. Thus count on to pay double value for the 200 Watt panel, in comparison to the 100 Watt panel.
The output of a panel also impacts the physical size of the panel, which means the 200Watt panel are going to be bigger in size for the one hundred Watt panel.
The kind of solar cells applied in its production also determines the size of your solar panel. They crucial issue to think about is that your system all round has enough Watts to power your appliances, and that the solar panels will physically fit within the area you wish to set up them.
Solar Panel Efficiency
There's a great deal debate about efficiency in solar panels, i.e. how productive the panel is in converting sunlight to electrical energy; but the crucial point to remember is the fact that a 100 watt solar panel will produce one hundred watts; irrespective of its efficiency ratings.
Solar Cell Variety
There are actually 3 main kinds of solar cells.
Mono-crystalline silicon
Essentially the most efficient and produces the smallest solar cells, and thus the smallest panels.
Poly-crystalline (or multi-crystalline) silicon
Produces the following most efficient form of cells, but equivalent wattage panels are larger than their monocrystalline counterparts
Amorphous (or thin-film) silicon
Uses the least amount of silicon and also produces the least efficient solar cells. This suggests thin film system take up extra location than the other two, however it has the advantage of offering flexible panels which will be utilised on curved or irregular surfaces not suited to strong panels.
Solar Panel Suitability
Mono-crystalline and multi-crystalline work extremely well in bright cool conditions, whereas amorphous (thin-film) silicon might be extra efficient at larger temperatures.
We generally recommend monocrystalline or multi-crystalline for significant unshaded roofs, and amorphous panels for roofs with partial shading.
Irrespective of the technologies currently in use, a solar panel in full shade will only generate a small fraction of its rated capacity; so the "shade tolerant" options you could possibly see advertised is usually somewhat misleading.
