Choosing Solar Panels Brands
There are many solar panels brands around, all claiming to be the best. LG is the biggest solar panels manufacturer, with its high efficiency solar cell coming in at almost 20.8%. However, they offer quality products, and while the price is a bit on the higher end, it’s not too costly as, at the normal wholesale price. When looked at on a wider scale, they might not be as efficient, but are more reliable, meaning they will last longer.
Photovoltaic cells come in a range of types, efficiency, brands and even shapes. And each one will vary slightly in price. At the low end, mass produce solar panels can be had for as little as $200. However, these are for mass production, where the company manufacturing them has no real concern for the overall efficiency or life of the product, merely the immediate financial injection of cash into the business. In contrast, those offering a higher degree of quality and reliability, a warranty, for example, are aimed at consumers who want something a little more reliable in their installation.
When comparing solar panels brands, one of the most important things to look for is the ‘warranty of operation’ or the life of the cells solar panel. While the warranty is not legally required, it’s always a good idea to check. Some panels have a five year guarantee of operation, others have ten. The better companies offering a longer guarantee offer an eight-year guarantee on the actual equipment, plus a further four years for the installation. And some manufacturers offer what are called ‘performance warranties’, meaning that the manufacturer will repair or replace their equipment should it suffer from a problem. This might be particularly important if the installation was carried out by an amateur, as companies with this kind of ‘performance warranty’ would almost certainly carry out the repairs themselves.
Other things to compare when choosing solar panels brands include size and efficiency. Obviously, the larger the cell, the greater its efficiency, but how many of them are required for a given set of instructions? The larger the cells, the greater the number of them needed, but how many of those need to be produced for an installation to be complete? The larger the cells, the higher the price, but the higher efficiency means that the price per unit comes down. And then there is power quality to consider – are the individual cells of high quality? Depending on usage, they could be quite poor; but if all the cells are of high quality, a conversion system could be very efficient.
How long do the cells last? Although a few manufacturers of solar panels tend to claim that their products last longer than the manufacturer recommends, the reality is that how long a product lasts will depend greatly on usage. A good, long-lasting system may last up to 25 years, but a less than that one is not likely to offer the best value. It’s best to take a look at product reviews to find out whether a given product has been affected by the weather, for example, but in general, a product warranty of one year is reasonable.
A number of considerations should also be taken into account when choosing a solar panel brand, such as the availability of cells. It’s easy to find suppliers of panels and installers, but how many of them can actually produce the output your property requires? A common problem is that only a few companies are actually able to produce a high enough yield from each cell that produces actual electricity production. You might want to choose companies that have a proven track record in the industry to back up their claims, or alternatively, choose a brand that offers a guarantee. They should also offer advice about how best to assemble your solar panels to maximise electricity production.
