HOW TO INSTALL SOLAR POWER SYSTEM
Before you get started in designing a solar power system for your home (residential) or office building (commercial), you need to keep in mind the factors that will determine the size and number of solar panels you will install. These factors include:
- Total Power needs: The energy demand in your home depends on the lighting, power, systems and the appliances that will be powered using the electricity generated by the solar system. If you are already using electricity from the grid, you can find the energy you need from the panels by analyzing monthly energy bills. You can then decide to offset some or all of your electricity costs using solar power.
- Number of Sun Hours: The amount of electricity generated by a panel depends on the number of sun hours in that location. The more the hours, the more energy you will get with a few solar modules. However, if the hours are less, you might need to install more panels to generate the same amount of power. Therefore, you need to know the number of sun hours in your area before you proceed with solar panels installation.
- The Size and Design of Your Home: The physical size of your home determines how many solar panels you can install and where they can be mounted. For example, a big house means that you have a large roof that can accommodate many panels. But you can install them on the ground if you have a small rooftop and unused land in your home. The design of the roof will also determine whether it is possible to install the panels facing the direction of the sun.
We consider some other factors in order to design a functional solar power system for your home, office, buildings etc. Are you looking for Installers of Solar power systems in Nigeria, Ghana, Gambia, Cote d’voire, Sierra Leone and Cameroun, contact us at BASSCOMM today to get a quote for the price of a complete solar system in Nigeria.
Below is a Rule of thumb to have an idea of sizing a Solar Power system
- First thing to state is to know the total load you need the solar system to power. Let’s assume the total load is 2.4kW. Convert the 2.4kW to 3.0kVA.
Introducing tolerance, a 3.5kVA needs to be designed for.
- The different voltage sizes of solar power systems are: 12V, 24V, 48V, 96V, .etc. and Sizes of the solar panel includes: 150W, 280W, 330W, 500W, etc.
Note that when we refer to a 12V solar panel that means a panel that is designed to work with a 12V battery. The actual voltage of a 12V solar panel, when connected to a load, is close to 18 Vmp (Volts at maximum power). This is because a higher voltage source is required to charge a battery. If the battery and solar panel both started at the same voltage, the battery would not charge. A 12V solar panel can charge a 12V battery. A 24V solar panel or solar array (two 12V panels wired in series) is needed for a 24V battery bank, and 48V array is needed for 48V bank. If you try to charge a 12V battery with a 24V solar panel, you will be throwing over half of the panel’s power away. If you try to charge a 24V battery bank with a 12V solar panel, you will be throwing away 100% of the panel’s potential, and may actually drain the battery as well.
- 12V 3.5kVA Inverter would be needed
- Choosing a 300W 12V mono-crystalline solar panel,
Number of panels = Load/panel power rating
= 12 panels
Add 30% factor of safety = 12*1.3 =15.6panels
Therefore, a total number of sixteen (16) 300W mono-crystalline solar panels are needed.
- Total power from the 16 solar panels = 300 x 16 = 4800W
Using a 12V 200A Battery, battery power = 2400W
Number of batteries = 4800/2400 = 2 batteries
