All solar energy systems for homes look quite simple at first glance. You have the panels usually situated on the roof, some support construction, wiring and that is about it. However, if you closely inspect several solar energy systems, you will find that there are huge differences even between systems in the same neighborhood. These differences are due to the fact that different households have different energy needs and different access to the sun as a resource.
Solar is very dependent on local and global climate so location makes a huge difference. Those who live in the south-west of the U.S are blessed with an above average number of sunny days. This is why solar thrives in states such as California, Texas, Arizona Nevada and New Mexico.
To make sure that you can make good use of a solar panel installation, you need to calculate how much kilowatts you can produce in a year. Panels work even on a cloudy day, but their efficiency levels are between 10 to 20 percent of their total production capacity. Still, do not underestimate this percentage, as it plays a large role the efficiency of solar energy systems for homes.
The roof direction also plays a large role in the efficiency of the solar panels. Solar energy systems for homes usually have a roof mounted installation, so the panel's direction and angle depends on the roof. For all living in the northern hemisphere, the general rule of thumb is that panels should face true south. If one of your roof sides faces true south you are in luck as a perfect angle can be easily achieved with the installation construction.
Before discussing residential solar energy systems, it is important to define the goals you want to achieve.
These two questions can take the solar solutions in very different directions. Depending on your answers, you will probably need a different set of components.
A residential solar energy system that is completely independent from the grid operates with a lot of redundancy. This is due to the fact that you will need to use extra equipment to ensure that your electricity needs are covered 24/7. The system will involve more panels and a backup battery to support you during prolonged sun unavailability.
Grid-independent solutions are good for remote locations where even connecting to the grid would cost a lot or you simply need a small amount of electricity to run an irrigation system and a few appliances.
In most cases, maximum savings with solar energy systems for homes are achieved when you combine them with the grid. When the panels cannot match your needs, it is cheaper to simply buy the electricity you need from a supplier. The added expenses created by the components you need for an independent system can sometimes make solar not worth your while, so always make sure you do the math right.
