All around the world, solar power systems are gaining ground as more homeowners are going solar in a bid to reduce costs on energy in the long-term.
According to the SEIA, a record amount of residential solar capacity was installed in Q3 2019, and overall growth for 2019 is estimated at 23%. This growth is expected to increase over the next coming years. The efficiency of solar power and its reduced cost led to this rapid development.
Equipment Needed for Solar Power System
Let’s say you want to install a solar power system in the house and you are wondering what the equipment would be. You will be wondering also how much invested is needed and when will you break-even? There’s no need to worry because the next couple of heading shall be discussing your questions.
What is a solar panel system?
Solar panel systems are often referred to as PV or photovoltaic which are usually placed on roof top to absorb and convert the energy-packed photons of natural sunlight into a usable energy form.
Most of the residential solar power systems are grid-tied systems. This simply means that they are still connected to the power grid and can utilize it for backup power. Meanwhile in remote areas, the solar power system that is often installed is off-grid system which are not connected to any national grid.
The next step is for you to know the components of solar power systems. Below are the components:
- Solar panels
- Solar inverter
- Solar racking
- Solar performance monitoring
- Solar storage
- Solar panels
The solar panels form part of the components. The key features to look at for, is the cost, efficiency, warranty and the type of technology. There are majorly two types of solar panels, which are monocrystalline and polycrystalline panels. Although they perform similarly, the monocrystalline is more efficient and expensive.
Inverters also form key components of a solar power system. Their function is to convert the direct current (DC) produced by the solar panels into alternating current (AC) for home use. The three major types of inverter as follows:
- String or centralized: they are very cheap and sometimes inefficient. This is due to potential production loss if there is shading on the roof.
- Micro: although more expensive, they are also more efficient. They are attached together which allows for smooth operations even during shade.
- Power optimizers: although less expensive than micro inverters, they are more expensive than string or centralized inverters. They are installed in each panel. They optimize the DC output of each PV module which passes to a string inverter to enable conversion to AC power.
During solar power system installation, the solar panels are not placed directly on the roof. They are placed on solar racking systems which are first fixed to the roof in order to receive a maximum degree of sun exposure.
Solar performance monitoring
This is being used to monitor the performance of the PV system. It is used to show how much electricity that is being generated at a time (per hour, day or year).
Every solar power system needs a battery for storage of energy to be used later, usually when there’s no longer sun. there are solar batteries designed for this purpose.
Cost of a Solar Power System
After knowing the key components of a solar power system, the next question in your mind would be the cost of owning a system.
There is no one price for a solar power system since we do not all have the same energy requirements and technology varies. Usually, as professionals, we will ask you some few questions which we shall use to determine the right system for you. simply send us an email or give us a call for a free consultation.
Also keep in mind that your solar power has a lifespan of about 25 to 30 years and we offer quality batteries with 3 years warranty. This means after, the initial cost of installation of your solar power system, you will have no recurrent expenses anymore.
