Strategies For Choosing Solar Power
Von marvinmikkelson, 11:41Thinking of utilizing power from the sun as a method of greening your lifetime and lightening your environmental footprint? When shopping for panels with regards to your solar energy system, there are a selection of factors worth looking at.
Cost
The cost of a solar panel is set in part by size (in Watts), the physical size, the company, the durability / longevity (or warranty period) as well as certifications the solar panel could possibly have. Buying a solar panel on price alone will never be wise, as it can certainly not fit the neighborhood you want to install it, might not have the desired certifications to receive government rebates, or may not have the warranty necessary for economic payback in the power produced.
Durability / Longevity / Warranty
The durability or longevity on the solar panel is significant for a variety of reasons. Firstly, when the solar panel only has a 10 year warranty and it is included in a grid connect system you should expect the solar panel to provide enough power to buy itself within a decade.
If ever the panel is being applied to a key system you shouldn't risk installing solar panel products that aren't as robust as the others, also. Reputable solar energy panels will likely have warranty a period of 25 years.
Solar Panel Size and Wattage
The dimensions of the solar panel in Watts will directly modify the price, as sun power panels are frequently priced (and compared) in dollars per Watt.
Watts are based on the production of each panel; meaning a 100 Watt panel under ideal conditions will generate 100 Watts of electricity each hour and also a 200 Watt panel will generate 200 Watts each hour. Therefore expect to pay double price with the 200 Watt panel, as compared to the 100 Watt panel.
The production of a panel also affects the physical scale of the panel, meaning the 200Watt panel will undoubtedly be larger in proportions on the 100 Watt panel.
The actual solar panels utilised in its production also determines the length of the solar panel. Your pc overall has enough Watts to power your appliances, and therefore the sun power panels will physically active in your community you would like to install them,. That's they key issue to consider.
Solar Panel Efficiency
There's much debate about efficiency in solar energy panels, i.e. how effective the panel is within converting sunlight to electricity; though the key point to remember would be that a 100 watt solar panel will produce 100 watts; no matter what its efficiency ratings.
Solar Cell Type
You can get 3 main types of solar cells.
Mono-crystalline silicon
The most beneficial and produces the tiniest solar cells, and so the littlest panels.
Poly-crystalline (or multi-crystalline) silicon
Produces the following handiest sort of cells, but equivalent wattage panels are bigger than their monocrystalline counterparts
Amorphous (or thin-film) silicon
Uses minimal quantity of silicon and likewise produces the least efficient solar cells. It has got the advantages of offering flexible panels that can be used on curved or irregular surfaces not suitable for solid panels, though what this means is thin film system require more area when compared to the other two.
Solar Panel Suitability
Mono-crystalline and multi-crystalline work wonderfully in bright cool conditions, whereas amorphous (thin-film) silicon are usually more efficient at higher temperatures.
We generally recommend monocrystalline or multi-crystalline for large unshaded roofs, and amorphous panels for roofs with partial shading.
Regardless of the technology currently in use, a solar panel entirely shade only will generate a small fraction of their rated capacity; so that the "shade tolerant" features you could see advertised is often somewhat misleading.
