Buying a solar system in Nigeria can be confusing.
There are many brands of solar panels, inverters and batteries available, with different prices and specifications. Choosing the wrong combination can result in poor backup time, frequent overloads and unnecessary expenses.
Before spending your money, it helps to understand the main parts of a solar system.
Solar Panels
Solar panels convert sunlight into electricity.
The number of panels you need depends on how much electricity you consume, your battery capacity, available installation space and how quickly you want your batteries charged.
Panel quality also matters. Customers should consider reputable manufacturers, warranties and product specifications rather than choosing based only on price.
Solar Inverters
The inverter manages electricity used by your appliances.
You will often see inverter sizes such as 3kVA, 5kVA, 10kVA and above.
However, a bigger inverter does not automatically mean longer backup time.
The inverter determines how much load the system can handle, while the battery determines how much energy is stored.
Both must be correctly sized.
Solar Batteries
Batteries store electricity so you can use solar energy at night or during power outages.
Two common categories are traditional lead-acid batteries and lithium batteries.
Lithium batteries are increasingly popular because they can offer advantages such as:
- More usable capacity
- Longer cycle life
- Faster charging
- Lower maintenance
However, battery quality differs between manufacturers, so brand, warranty and compatibility with your inverter should be considered.
What Determines the Size of Your Solar System?
The number of bedrooms in your house does not determine the solar system you need.
Your appliances do.
For example, a home using lights, fans, TV and refrigerator requires much less electricity than one running multiple air conditioners, freezers, pumps and washing machines.
Before installation, tell your provider about all major appliances you intend to use.
Don’t Ignore Installation Quality
Even high-quality equipment can perform poorly when installed incorrectly.
A professional installation should consider:
- Correct cable sizes
- Proper panel mounting
- Breakers and protection devices
- Surge protection
- Earthing
- Correct inverter settings
- Safe battery installation
Choosing an installer purely because they offered the cheapest price can become expensive later.
How to Compare Solar Quotations
When comparing two quotations, don’t look at the total price alone.
Compare the:
- Solar-panel capacity
- Inverter brand and size
- Battery type and capacity
- Protection equipment
- Installation quality
- Warranty
- After-sales support
A more complete system may cost slightly more initially but provide much better value over time.
