Nowadays, having a more sustainable source of energy to power your home is the latest trend. Many homeowners have now incorporated the use of solar energy to their home’s energy supply. Aside from the financial savings you could enjoy, this type of system is also more environment-friendly than the traditional electricity source.
If you’re considering switching into solar power system for your home or simply want to incorporate it as an alternative energy source, you’ll need to know the basics first to get it the right way. Here are the basic you need to know about solar power and how to use it for your home.
Solar power systems are not that complex. They are basically composed of 3 parts. First, the solar panels which are attached to the roof or on-ground. These could either be monocrystalline or polycrystalline. Although these 2 are different, it doesn’t matter that much whichever you choose to install since both serve just the same purpose. What matters most is that you go for high quality brands that are tried and tested to last for many years on your roof. These types of solar panels cost more but your investment will surely be worth it in the long run.
Next is the inverter, which converts the DC electricity coming from solar panels into AC which is used to power your home. The inverter is most likely the first to have problems in your solar power system because they work all day, making them more prone to regular wear. The solar panels are connected to it through a micro-inverter on the back of the panels.
Third is the racking or mounting system for your solar panels. This part is attached to your roof to hold the solar panels securely in place.
Number of Panels You Need
Basically, the number of panels you’ll need depends on how much energy your home uses up in a day. However, it is also affected by you budget and the space available on your roof or yard where you could mount your solar power system. For a typical home, 22 panels with a 5-kilowatt inverter are enough to provide for its energy consumption. However, you may want to consider adding more to compensate for winter or overcast days when there is lesser solar energy absorbed from the sun.
Panel Direction and Angle
It is true that solar panel direction and angle have an effect on the amount of energy produced by the panels. For instance, there will be a peak energy production in the morning if you have east-facing panels. For west-facing panels, most of its production will be in the afternoon. North-facing panels are said to be the most efficient since it peaks energy production during midday, providing you the most energy compared to other directions.
With this basic information about solar power, you can now start planning on how you could add this to you home and even understand more about what a solar salesman explains to you.
