Solar panels and the whole concept of solar energy is gaining popularity around the world. Solar is of course the cleanest form of energy we know so far. As more and more houses and commercial setups convert to solar energy, prices for the technology will come down as well. So, does solar panel size matter? Is bigger the better in the case of solar panels? There might be more hiding under plain sight.
So, you have researched your local service providers and now want the best option? Of course, there is a standard size when it comes to solar panels. Yet, there is no limitation when it comes to their sizes, shapes for these panels. Also, many manufacturers do follow certain size guidelines. Here is what you need to know when it comes to sizes of different solar panels:
Solar Panel Size and What It Means for Consumers?
Of course, more surface area for solar panels means more power output. However, size of an individual panel might not be the only factor for the system efficiency. And yes, efficiency and reliability are more important factors than sizes for these panels.
Firstly, when you get the chance to buy larger panels, fewer will be needed to produce the required power. Also, larger panels might cost less than smaller ones when combined into a system. So, if smaller 20 panels are needed for a home, somewhat larger panels might come down to 15 for same power.
What this all means is the cost factor and in some cases the space availability. Homeowners need to decide based on these two factors on the size of their solar panels. The overall system requirement will most likely stay the same with similar power output.
Core Efficiency Factor for Solar Panels
Ultimately, it will all come down the efficiency. Bigger the solar panel, more sunlight it will be able to take. More sunlight will mean more energy it can produce. However, more smaller panels can combine to provide the same amount of surface area.
Commonly, most solar panels are about 41 inches wide and 62 inches tall. There are smaller versions available in different parts of the world as well and some larger ones. On average, a solar panel size of this measurement produces from 270-320 watts power.
The very best solar panels with high premium efficiency are able to produce upwards of 370-420 watts. This increase in efficiency with the same panel size is due to material selection. Manufacturing plays a vital role. So, better panels are able to produce more energy while keeping the size same.
How Some Panels Can Be More Efficient Than Others?
Efficiency for solar panels really comes down to the cell technology in use. Of course, panels are made from these solar cells. Shading is often something associated with solar panel efficiency drop. Some of the best panels have all their wires right at the back of the cell to carry energy.
The foundation of solar cells on panels plays a vital role as well. Copper foundations have been found to produce better efficiency. These copper foundations function better in high temperatures producing more power output. Also, the reflection properties of that glass on top of the cells impacts as well.
Anti-reflective glass usage for the panels makes them absorb more sunlight without reflecting much back. The purity of silicon for the solar cells impacts efficiency too. So, in addition to solar panel size, there are many other factors that make some panels produce more power than others.
Are There Larger Solar Panels Available in the Market?
Simply, yes. There are larger panels available in the market as well. Also, there are smaller panels readily available as well. However, the most commonly found ones are of the size dimensions mentioned above. Yet, sizes might not actually impact the overall efficiency of your solar storage system.
Cost factor with sizes will be important for homeowners as well. It is all about calculating the overall cost for your solar system including all the panels it will need. Do the costing for smaller panels and also the larger panels as available. Then also consider the rated efficiency of the panels for best results.
How Does Solar Panel Size Help Homeowners?
Solar panel sizes play vital roles when it comes to installation. Solar installers also recommend sizes after having assessed your installation space availability. Some roofs with be different to others in their dimensions. Also, some with be wide where others will be taller.
For the required power generation, how many taller panels or smaller panels the space is able to fit is important. Where you will need more smaller panels that might cover more space in any dimension, larger panels might fit better. Ask a professional service provider for help on size of solar panels.
Reliability, Efficiency and Durability Are More Important Factors
Of course, solar panel reliability, durability and efficiency are the more important factors. You cannot rely on their sizes alone. The overall system must be able to provide the amount of energy your home needs. It should be able to deliver the required energy in the best way possible as well.
Solar panel size will be an important factor for installation space consideration. However, more decisions should be based on their reliability, efficiency and durability. So, select the best panels and solar system for your home to avail greater benefits for longer periods of time.
