Investing in a solar panel system is an important decision. It is designed to last a long time, so it pays to do your homework before getting a deal. Get the essential information you need to understand your options and decide based on major considerations. It also helps to speak with experts or reputable companies to find out which panel best suits your home.
There are three most common materials used for solar panels, namely monocrystalline, multicrystalline or polycrystalline and quasi-monocrystalline. Monocrystalline is highly efficient and heat tolerant. It is often used where space is limited. It has been in use for many years now because it degrades slowly. Multicrystalline or polycrystalline is the second most popular choice for residential applications. It has good quality silicon that’s excellent for any climate and remote areas. The last one, or quasi-monocrystalline, is a hybrid material that morphs the qualities of monocrystalline and polycrystalline panels, so it features the best of the two materials.
The warranty is a very important consideration when buying solar panels. It should be between 10 to 20 years. It is best to check the installer’s track record regarding their warranty. Of course, if they were no longer operating, whom would you chase for the warranty? A long warranty also indicates their confidence in their product. In this regard, it is also worth choosing a popular brand of solar panel even if that means a higher cost.
The higher the wattage of solar panels, the costlier they are. A 100-watt solar panel can produce 100 watts of electricity/hour, so if you go for a 200-watt solar panel that produces 200 watts of electricity/hour, you will pay double. Higher wattage also means a bigger physical size of panel. You must be sure that the size of the panels you choose suits the size of your roof. You can use your energy bill to determine the ideal size you need by checking your household’s energy consumption.
The solar panel price is determined by size, quality, brand, warranty, durability, and certifications. Have a realistic expectation in terms of price. You can get several quotes from top installers to have an idea of the average cost and weigh them up based on their offering.
To convert sunlight into a usable form of energy for your home, you need an inverter, the important component of the solar energy installation. Not all inverters are the same, so make sure to choose an efficient inverter to make the most of your investment. Making the switch to solar power is a lifelong venture that can save you money, so it pays to do it right.
With the many things to learn about solar panel systems, it is easy to be confused. Make sure to remember this checklist of factors to help you make an informed decision when buying solar panels for your home.
