Solar Cell Efficiency VS Cost


In regards to selecting solar cells for your do-it-yourself endeavors, 1 question many need is does solar cell efficiency matter? Answering that is actually quite easy.

The answer is yes, solar cell efficacy does matter. The important point to note here is that it may well not be for exactly the exact reasons you would think. It isn’t choosing the most efficient cells which things the most, it’s balancing cost versus efficacy which may make most of the difference to the ultimate price of one’s solar energy system.โคมไฟโซล่าเซลล์​

Without stepping into the different levels of solar cells, or talking about how you’re able to save money by choosing standard B cells, so let us discuss how to correctly balance these two areas of constructing a solar panel (or several them).

Solar Cell Efficiency at Summary.

When it comes to selecting the ideal solar cells, then my proposal is usually to stick with your normal poly crystalline cell. These types of cells are readily available on the home based markets, and as far as efficacy is concerned the majority are rated at 16 percent – 20 percent efficacy. To translate that into a number which is more usable.

These are the most useful cells to utilize while building solar panels to get a simple reason – cost. Your typical poly crystalline cell can be found for as low as $1.50 per ( less should you choose grade B cells) and they often average around $1.80 on sites like eBay. Utilizing this type of cell you can construct a whole 100 Watt panel with approximately $85 worthiness of cells.

Where a few confusion is beginning to appear is with the availability of 30% to 35% efficient solar cells. Even though these are not yet as common on the home improvement markets, they are getting to be available and some people are wanting to raise the efficacy of their home solar energy method using these cells.

The issue isn’t that highefficiency mono-crystalline, or thin film, cells don’t get the job done. You can just as easily construct a solar panel utilizing this particular technology as you could with the older cells that are standard. The issue is that the price. With the new 30% cells costing up to five times more than the usual normal cell, they simply aren’t worth it. You pay five times more for only a 10 percent gain in power output.

In case you had ascertained that you had 10, 100Watt, solar panels to run your home, with the normal cells you could feasibly expect you’ll build your panels about $850 values of cells. To construct the exact system from the with high efficiency cells you’d still need 9 panels, and also the cost of these cells could suddenly increase to roughly $3825.

Therefore to answer our initial question, yes solar cell efficiency matters. But maybe not because why you probably thought; it’s balancing cost versus efficacy which will really make the big difference once you convert your own home to solar power.
