Solar installation is becoming more and more popular these days. Many people are choosing to go solar for various reasons. With this growing popularity, it is important for you to know what solar panels are and the things you need to consider before employing the services of solar companies. According to a report from the International Energy Agency in 2017, solar has become the world’s fastest-growing source of power. This report further proves that solar energy’s growth has surpassed that of all other fuels.
What are solar panels?
Solar panels are a collection or assembly of solar cells that spread over a large area converting light directly into electricity. These solar cells are made of silicon which is a semi-conductor material that allows the cells to convert sunlight into electricity for use in a home. Solar cells are constructed with a positive layer and a negative layer that create an electric field together. The cells are arranged in a grid-like pattern on the surface of solar panels. The more sunlight that hits a solar cell, the more electricity it produces.
What to consider before installation
Having the best solar panels for your roof can be quite expensive and the decision of whether you installation of solar or not is very important. If you decide on using solar energy in your home or office, there are several things you need to consider.
-First you need to be sure that your roof supports solar installation. Roofs made of strong and durable roofing materials like asphalt shingle are very suitable for solar panels. Other roofs like those made of wood shake or clay roofing materials will require the experience of professional solar companies.
-The exposure of your roof to sunlight is also an important factor to take into consideration. If your roof is in the shade and very often not exposed to sunlight throughout the year, then installation of solar may not be a good idea. Solar panels will work for roofs that are exposed regularly to the sun. You can also set up a solar consultation appointment with an expert who will check your roofs and surroundings and determine if your roof will receive enough sunlight for your family’s energy needs.
-Also, the condition of your roof needs is a very important factor before you start any solar installation process. . If your roof is old and needs to be renovated or replaced in the next few years, then it will be better to have it renovated or replaced before commencing with your installation. This is because solar panels have a long lifespan and will need to stay on for many years. This will also prevent you from spending more in the future to disconnect and put back your solar panel due to a roof renovation or replacement.
-In addition to knowing the condition of your roof, you need to be sure that you do not plan on leaving your home or moving out soon. Solar panels are a long term investment and shouldn’t be installed if your job requires you to change locations.
-Again, you need to be sure if your house really needs solar based on how much you are paying for energy. The decision to move to solar is very often as a result of high electricity bills. However, the cost of electricity is relatively low in some areas and very high on others. You need to be sure that installing solar panels will be a cost effective choice
-Also, you need to be sure that the solar panel will generate enough electricity to power your home. Electricity consumption differs from home to home. Knowing what your electricity needs for your home or office are will enable you to know if a solar panel will be able to meet these needs. This also helps you know how many solar panels you will need to buy
-You will also need to take into consideration the climatic conditions of your area. Solar panels depend on the rays from sunlight to produce electricity or heat for your home. Knowing the climatic condition of your area will help you determine if going solar is a good idea or not. It will also help you determine the type you should go for. Some solar panels still remain effective even when the weather is cloudy.
-Another thing worth taking into consideration before installation is the type of solar that will be good for you. Photovoltaic and Thermal are the best solar panels and the dominant solar panels. Photovoltaic panels uses arrays of cells to turn light into electricity while Thermal panels use sunlight to heat water or air for use in the building. Deciding on which of these two you will need depends on your environment. Photovoltaic panels are however popular for home use.
-Again, you need to research on solar companies around you and be sure that the company you are hiring is trustworthy and will be available to fix any problems that may arise during your warranty period. Also be sure that the company you are working with has lots of experience in the field and makes the best solar panels.
-Also, you need to decide whether you will buy or lease the solar panels. Leasing will allow you to have access to cheaper electricity while paying some money to the company. However the panel is owned by the solar company and they will collect it back when the lease is up. Buying on the other hand is more expensive but saves you from any future payments. You own the system and can use is for as long as you want. Planning your budget well and deciding on which will be more cost effective for you is important.
-In addition, you need to ensure that your contract contains all the details of the work from financing to system ownership. If you doubt anything, you need to ask before signing any contracts. This will avoid any future problems.
