How to maximise output from solar panels

Sustaining Our World Posted on March 20, 2024 by David GuionMarch 20, 2024
Contributed by Rawal Ahmed With solar panels becoming a more viable option for many homes across the globe, it can be important to know what you’re getting into before you opt to install them. This is especially true as they can be quite an initial investment, which makes it all the more important to get the most out of them. Here are a few tips for how to maximise output from your solar panels. It all begins with choosing the right panel setup This might sound obvious, but it all starts with what type of solar panels you have. Much like a good meal, maximising solar panel efficiency is all about having the right ingredients. In this case, those would be the power of your panels, how they are set up, and the sunlight hours you get. The power of your panels depends primarily on how large your setup is in output size. The maximum size can vary from country to country, but most experts recommend 4kW to 5kW per single-phase connection. Any more than that might require permission from your energy provider. Permission is not needed for systems with an inverter up to or under 3.68kW for a single-phase supply or 11.04kW for a three-phase supply. You should also consider the type of solar panels you want. Integrated solar panels, In-roof solar panels, or solar tiles produce less power than on-roof panels and arrays. However, they also take up less space and can look more pleasing, so you need to weigh aesthetics up against maximising power production. Primarily you need to know your home’s power requirements, what type of inverter you have, and which solar panels will suit it. For example, if you have a string inverter (this contains a chain of solar panels grouped together or put into rows connected in series) all the panels in a string must be at the same pitch and orientation. Other inverters have different needs. Be sure to know the specifics of your inverter to optimise your setup. Maximising your setup doesn’t just include your panels and inverter, however. It’s also about your storage options for when the sun isn’t out and about. A solar battery can help you make use of any excess energy you store and provide electricity at night. This is handy if you can manage to set up a higher power system which can save up a lot more during the day. Location & making the most of your sunlight hours Where you place your solar panels can have drastic effects on their efficiency. Ideally, you would want a large roof facing, or one that allows the panels to face, the right direction. In the northern hemisphere, they need to align southward at a 30 to 45-degree inclination. Moreover, even if they do face the proper way, the sunlight must be unobstructed by shade. Minimising sunlight through proper gardening and tree maintenance might be necessary. Also, be sure to inform your neighbours that you’re installing solar panels. They should know to not block access to sunlight with any decorations or appliances they might put up. Barring a roof with ideal conditions, you could opt for solar panels on a terrace or balcony. However, this arrangement usually provides less space. To optimise efficiency, roof tiles and on-roof solar panels are ideal, although you can manage with smaller panels on a roof if your energy needs are not too demanding. How to maximise solar panel output with maintenance Dust and other types of environmental hazards can diminish solar panel output. Dust can decrease output by up to 7% in Western Countries and up to 50% in the Middle East, according to researchers. Especially during the winter months, it’s best to clean up snow and frost that might block the panels from receiving sunlight. Be sure to plan for maintenance and ensure physical accessibility for your solar panel system. Make sure you can reach them for repairs or some light cleaning. While it can sound like a chore, it is refreshing to know that most solar panels are not easily blocked from light access. Modern panels can still absorb sunlight through 5 to 8-centimetre layers (2 to 3 inches) of transparent snow. This means they can endure harsher weather conditions and can even work around light sprinklings of dust. Similarly, rain and wind tend to have a cleaning effect on most panels. Likewise, the inclination of an array often helps keep obstructive particles off. All in all, some weather conditions can help keep solar panels a bit cleaner. Monitoring performance Finally, it’s crucial that when you install solar panels, you track their performance. Make sure you know how they’re doing on the field so you can improve them. Measure this performance across the years you use them and make sure you know when it's time for some maintenance or angle correction. Typically, solar monitoring systems or software are installed alongside the panel itself, but you can also acquire aftermarket systems. With such a system, you can track your performance with the help of a wifi connection. These can make it far easier to identify potential problems as they happen. Some monitoring programs have additional benefits such as the ability to link them up to financial software to have an overview of your savings and some projections. With these tips in mind, you can make the most of your solar panel system and live more sustainably.
