Planning to purchase a photovoltaic system means exploring whether it is time to buy a solar panel or a number of panels to provide sufficient energy for a property. There is no singular system that provides adequate power needs for every individual purchase. Instead, consumers are faced with a number of considerations to insure a proper system for the need. A lot depends on the property size, the power needs, and the location, depending on where the system will eventually be installed.
The first thing to consider is the daily power consumption of the property. It is necessary to find out how many watts the property utilizes on a daily basis. Taking a look at past utility bills is a good way to find out how many watts are utilized. Most utility companies will provide a breakdown of usage for the day, month, and past months. Generally, a purchaser will want to go with the highest usage days instead of taking an average of the daily numbers. That average will not keep the purchaser in power on high watt months or days.
Next it is important to investigate the peak sunlight average on a daily basis. To buy a solar panel system sufficient for the property and to calculate the solar latitude, an average will be necessary. Be generous when it comes to that daily average, because having a bit too much is better than not enough. In addition, many utility companies will purchase the excess power back from the homeowner, allowing the property owner to actually make a little bit of cash on the side. Knowing the average peak sunlight during a given day may seem daunting, but it is simple to figure out by contacting a professional installer and allowing them to do the figures.
The professional will not only be able to install the system properly, but they also know the important factors that will make the system work to its fullest potential for the homeowner. By knowing the longitude, latitude, and appropriate time zone, the installer can chart the path of the sun displaying the ideal average for the purchaser.
They will divide the watts used on a daily basis by the average peak sunlight hours. The answer provided will be how many watts per hour that will need to be generated to have a functional system capable of providing energy for the property in question.
How does this help a purchaser buy a solar panel system?
Each of those panels is given a watts rating. For example, a 100-watt section produces 100-watts of energy every hour that peak sunlight is available. So if a property needs 400-watts every hour to remain functional, the purchaser would need to have 4 100-watt units, 10 40-watt units, or 1 400-watt unit installed. Every property need will vary individually and change the number of units that are necessary for the homeowner to buy. A solar panel system is indeed as unique as the purchaser and the property.
Another factor a purchaser should consider is the ability to combine photovoltaic energy and the utility company. This ability to purchase the system a piece at a time helps the purchaser save money and add on as the budget allows. This means that the homeowner can buy a single solar panel as money permits, enjoying the benefits of self-sufficiency one step at a time. The investment is minimal to start and the final results are well worth the time and effort.
