The link between energy use and climate change is undeniable. The, fewer fossil fuels we need to burn, the less damage and harm we’ll do to the planet and the environment.
Solar energy has numerous benefits to offer consumers but, given that you’re here, we imagine you’re already more than familiar with them. Having assessed your options and weighed up their advantages, you now find yourself thinking of switching to clean electricity but you’re not quite sure how to select the perfect panels.
If we’re working along the right lines so far, you’ve come to the right place. As experts in solar energy, we’re about to give you four top tips to guide your decision-making. Hopefully, this list will serve as a guide to make a good purchase.
1. Solar Panel Cost
Whilst cost shouldn’t be the only factor that guides your choice of solar panel, it’s fair to say it’s an important consideration for most people. The solar panel cost is determined by different variables: the size (in Watts), the physical size, the brand, the quality of the materials, the durability (or warranty period) and any certifications the solar panel might have. How to choose solar panels can be risky but, they have a long lifespan (more than 30 years), so it is more important to ensure a good quality system rather than choosing the cheapest option.
2. Assess their energy efficiency
Solar panel efficiency is a measure of the amount of solar energy (irradiation) which falls on a panel surface and is converted into electricity. The more efficient, the better (and more expensive). It is not always the best choice to get the biggest and most efficient solar panel since you might end up spending more money than you should cover your energy needs.
Before choosing the solar panels, you should assess your requirements and find the panel that best suits your needs: this means not underestimate, but also not to overestimate your needs.
3. Temperature Coefficient
Temperature Coefficiency refers to the impact that heat has on a solar panel’s operational efficiency after installation. Since solar panel overheating accelerates their ageing, the lower the percentage per degree Celsius, the better.
This could be an indicator of the manufacturer’s confidence in its products. Manufacturers who have full faith in their products will typically offer a 25-year warranty term so, if you can find something that ticks this box and all of your others, you’re likely onto a winner. If a long warranty period is not included as standard, take this as a warning sign, and no matter how good the price, keep on searching until you find a better option.
Of course, it is also important to properly maintain your solar panels to increase their lifespan. Fortunately, they are easy to take care of and don’t require much maintenance.
This takes into account the physical size and the size in Watts. You should make sure to install a solar panel system that is big enough to power all your appliances, and also that you have the space required to install it.
The physical size of the panel will vary depending on how powerful the system is (the more Watts, the bigger) and the type of solar cells used to build the panel.
