Solar system have gained a lot of popularity across the globe due to its low maintenance costs, environment friendly feature and more. It is a generally acceptable fact that solar power is the cleanest and most reliable form of renewable energy available at the moment. However, the solar energy (sun) will not just light up your house automatically, it requires the help of two components “the Solar Panel” to absorb the solar energy and the battery to store the current before it is pass through the house.
Solar panel is designed to absorb the sun’s rays as a source of energy for generating electricity or heating. It collects solar energy during daytime and used at the time of need after being converted into electrical energy. There are different types of panel, hence you need the guide to help you choose the best solar panel for your home
Tips To Choosing The Best Solar Panel
Determine Which Type of Panels You Want
There are two main types of solar panel, the Monocrystalline and polycrystalline panels also refers to as Mono or poly solar panel. Both poly and mono solar panels have cells made of silicon wafers. However, the Mono solar panel are more efficient with good heat tolerance characteristics, longer life span and are quiet costly compare to the poly solar panel which offers lower efficiency rate, a shorter lifespan and cheaper.
Solar Panel Capacity
After determining which type of solar panel you want there is also the need to know what solar panel capacity will best serve you. Not all solar panels are alike. Photovoltaic (PV) solar panels (most commonly used in residential installations) come in wattage ranging from about 50 watts to 400 watts per panel. Mono panel however ranges from 150 watt to about 400 although, some company offers more.
Determining the energy efficiency of your panel is necessary because it points out how much of the light received is converted into electrical energy. To figure out what panels watt you need, divide your home’s hourly wattage requirement with how many panel you can afford. The higher the wattage, the bigger your solar panels will be in physical size,
Solar panel’s warranty is an important consideration when choosing solar panels. It guarantee you of your panel reliability and production output. A solar panel has two warranties: a performance and equipment guarantee. The solar panel’s performance warranty will typically guarantee 90% production at 10 years and 80% at 25 years. An equipment warranty will typically guarantee 10-12 years without failing.
Solar Panel Tolerance Level
Although, it is generally noted that mono panel comes with a high tolerance level, you need to confirm your Panel tolerance level is high because solar panel efficiency is affected negatively by temperature increases. Before you buy a solar panel check the manufacturer’s data sheet maximum power temperature coefficient. With this, you will know how much electrical power a panel can produce above or below its rated capacity at any time.
Energy Conversion Efficiency
Just as it is important to know your panel tolerance level, you must also check for the panel energy conversion efficiency level before purchase. Solar panel efficiency is one useful metric used to determine how much power a panel produces compared to other products.
Measuring efficiency is fairly simple. If a solar panel has 20 percent efficiency, that means it’s capable of converting 20 percent of the sunshine hitting it into electricity. The highest efficiency solar panels on the market today can reach almost 23 percent efficiency. The average efficiency of solar panels falls between the 17 to 19 percent efficiency range.
After Knowing what to look out for when buy solar panel, the next question people ask is how many panel do i need? well lets see how to calculate the number of panel needed for your solar installation.
How many solar panels do I need for my home?
The first step is know how much energy your household uses. Then you can calculate how many solar panels you need by multiplying your household’ s energy usage (daily and hourly usage) requirement by the peak sunlight hours for your area and divide it by a panel’s wattage.
Best Solar Panel Prices in Nigeria
Solar panel prices varies depending on different factors, including, the wattage, manufacturer and type. The cheapest solar panel are the poly panels because they are available in the lowest watt with lower efficiency rate and life span.
