What is needed for a solar power system
The sun is not only a source of heat and light; it is also a source of energy.
Solar energy (or solar power) is the electricity generated by the sun. We can transform energy from the sun’s beams into electricity that powers our televisions, refrigerators, lights, and other appliances via a process called the photovoltaic effect.
If you’re consideringinstallation, you’ve definitely spent some time investigating financing options, tax incentives, and solar installers. You should, however, educate yourself on the solar energy equipment required to get your system up and operating. We’ll dissect all aspects of solar power equipment in order to best prepare you to make your hardware selection.
Solar panel system components
Solar panels, commonly referred to as solar cells or photovoltaic cells, are the foundation of solar energy systems. Solar panels come in a variety of configurations, including polycrystalline and monocrystalline. Monocrystallineare more efficient and slightly more expensive than polycrystalline solar panels. Solar panels are selected based on a variety of factors, including space, warranty, efficiency, technology type, and cost.
In general, the solar panel is connected directly to the charge controller, but solar panel arrays can be connected in series or parallel, depending on the load calculation and specific energy requirements of home appliances, battery bank connection, roof surface area, climate, and peak sunlight hours.
As the name implies, a charge controller (alternatively referred to as a charge regulator) is a device that regulates the voltage and current flowing from solar panels connected to batteries. The primary function of a charge controller is to prevent batteries from being overcharged (which can cause damage to the battery) using solar panels, as 12V solar panels deliver 17-20V when there is no load or full sun.
Batteries are used to store backup charges. There are several types of batteries used ins for storage and backup operation throughout the night when solar panels are not producing direct power. In the event of cloud cover and lack of sunlight, the battery bank can be charged through an inverter using the alternating current supplied by the power grid.
UPS / Inverter
An inverter is a device that converts a direct current power supply to an alternating current power supply. The inverter and converter, collectively referred to as UPS (Uninterruptible Power Supply), is used to convert DC power to AC for usage with household appliances. Additionally, the UPS is used to convert AC to DC in order to charge the battery from a direct AC power supply.
Which solar power system is the best for a home?
The optimal solar power system for your home is determined by your objectives.
If your primary goal is to save money on your electricity bills while also powering your home with renewable energy, a grid-tied solar system is probably the best option for you. The hybrid solar energy systems are a better fit for homeowners that have grid access but yet face frequent power outages. Off-grid solutions are ideal for homeowners without grid access.
The best manufacturers have identified and partnered with qualified installers in each geographic area. Proper installation can be as critical to future performance and return on your investment as the quality of the equipment.
