Going solar has many advantages. But once you decide to take this big step, how can you be sure you will get the best possible results? We have collected some advice on how to maximise the efficiency of your rooftop solar panels so that you can fully enjoy the benefits.
Over the past years, the installation costs for solar panels have decreased significantly. Along with the energy costs it will save you and the massive reduction of your carbon footprint, there should be reason enough to seriously consider this step. But once you have made this exciting decision, how can you make sure you will get the best results possible? We want to to be happy with your choice, and have gathered some tips that will help you maximise the efficiency of your rooftop solar installation.
Choosing high quality panels
These days, solar cells are made almost entirely of silicon, which is why the quality of the silicon plays such an important role. In monocrystalline solar panels, large cylindrical-shaped silicon ingots are used, which are then cut into four to create the solar cells.
Monocrystalline solar arrays can be recognized by their uniform colour and rounded edges. While they are more efficient and heat-tolerant than the alternative, polycrystalline solar panels, they are also more expensive. Thus, if you have no limitations regarding space, you can also consider purchasing a larger number of polycrystalline cells.
Selecting the perfect spot
Do consider that the location of your installation affects the efficiency and output. The more sunlight is shed on it, the more efficiently your array will work, and the higher the energy output will be. As solar panels are usually wired in series, even one shady cell can affect the efficiency of the whole installation. If you cannot avoid shade altogether, try to go for an alternative to wiring the panels in series to reduce wasted efficiency.
Finding the ideal orientation
Different directions receive different amounts of sunlight, depending on where you are located on the globe. If you are based in the northern hemisphere, such as European countries or the United States, try and find a spot for your solar installation that faces South, as this will maximise the amount of sunlight it is exposed to. The position and elevation of your home should also be considered – something a professional installer will take into account. If it is hard to work accordingly on your roof, you might want to consider placing your installation on your yard.
Clear the way to best results
Even your solar installation needs a little cleaning – but only now and again. Make sure you hose it down every few months, particularly if you notice a drop in efficiency, as bird droppings or leaves can block the sunlight. Dust, however, will usually be washed off by rain.
