Energy sustainability is necessary for preserving natural resources and maintaining cost-efficiency. Solar Power utilisation assists in conserving energy and acquiring affordability in power consumption. Using solar power systems in your home is economical and environmentally friendly; however, proper utilisation might cause additional problems later.
“How do I choose a suitable solar battery and inverter?” is a common question that concerns the majority of first-time solar power users. For starters, your batteries, power inverters, and solar panels must be correctly chosen for long-term use and uninterrupted power supply.
We at Star Plus Battery can help you calculate solar panel, battery, and inverter specifications. Before you opt to buy solar inverters in Nigeria, check out this blog for a comprehensive understanding of utilising the best ways to utilise solar power.
How do you calculate solar panel batteries and inverters?
When you plan to install solar panels, batteries, and inverters, you need to decide on the capacity of these components. Check out how to be precise with the steps to calculate the number of solar panels required alongside battery capacity and inverter load. Here’s what you need to know:
Step 1: Calculate Your Load
The first step is to analyse your battery and inverter requirements to calculate the load that you consume. Equipment like clamp meters is used to calculate the load. You can directly get the reading from the electric meters after turning on your devices. Load is calculated by Watts (W) and Hours (H).
Step 2: Calculate Backup Time
Once you have calculated your power consumption, it’s time to calculate backup time. Backup timer refers to how many hours your device can run during a power outage. It is necessary to calculate the backup time of your battery after you start using solar energy. Here’s how you can calculate your battery storage:
Step 3: Calculate Battery Capacity
Now comes your inverter battery capacity. Each battery type had a different capacity for supplying power to household, commercial, and industrial regions. Our inverter battery installation and management experts will thoroughly assist you with your required battery storage and capacity. Expert guidance will help you choose the correct inverter battery.
Step 4: Analyse Inverter Capacity
Before you opt to buy a solar inverter battery in Nigeria, analyse your inverter’s capacity. First, you need to consult the power tolerance of an inverter. Consult with our battery management experts to get an overview of your inverter’s capacity.
Step 5: Solar Panel Capacity
Now comes your solar panel capacity for determining how many solar panels there are and how much power you need. Your requirements can vary as per the necessity of power consumption, quality of machinery function, and weather conditions.
Number of Solar Panels required for Charging Batteries
Suppose your battery capacity is 220 Amp-AH and your inverter voltage is 24 Volts; then your Watt Hours will be:
Amp-AH x Volts = 220 x 24 = 5280 Watt Hours.
Now, the average peak sunlight in Lagos stays on average for 4 hours. The total watt-hours need to be divided by 4 hours of daylight.
This results in an average sunlight hour of 5280/4 = 1320 hours.
Now, if the size of your solar panel is 300 watts, then the number of such solar panels can be calculated by dividing sunlight hours by that of solar panel capacity.
= 1320 hours/ 300 watts = 4.4 or rounding off to 4.
Hence, in such a real-time scenario, you will be required to have four solar panels to charge your inverter batteries.
Number of Solar Panels Required for Powering Load
Suppose you consume a total load of 875 Watts and a backup time of 4.83 hours; the total watt hours will be:
Load in watts x backup time = 875 x 4.83 = 4224
Suppose there is a 30% operation loss; then the total backup time will be:
4224 + 4224 x 30% = 5491
Now, if sunlight hours is 4 hours, the average hours of sunlight can be calculated by:
5491/ 4 hours = 1372.8 hours.
Now, if the size of your solar panel is 300 watts, then the number of such solar panels can be calculated by dividing sunlight hours by that of solar panel capacity.
= 1372.8 hours / 300 watts = 4.6 or rounding off to 5.
Hence, five solar panels will be required for powering load in your homes.
