Question 1

How do I know what size solar inverter I need for my home or business?

Accepted Answer

For basic residential loads (LED lighting, standing fans, TV, decoder, laptop, Wi-Fi router), a 1KVA to 2.5KVA system (12V or 24V) is ideal. For powering energy-efficient refrigerators, freezers, and 1HP–1.5HP inverter air conditioners, a 3.5KVA to 5KVA (24V or 48V) pure sine wave hybrid inverter is recommended. Commercial facilities, workshops, and large duplexes typically run on 7.5KVA, 10KVA, or 15KVA+ three-phase hybrid inverters.

Question 2

How many solar panels do I need to charge my battery bank?

Accepted Answer

The number of panels depends on your battery storage capacity and daily peak sunlight hours (typically 5 hours in Nigeria). A 12V 200Ah battery stores approximately 2.4kWh and pairs well with 2 to 3 450W–550W monocrystalline panels. A 48V 200Ah (10kWh) lithium battery bank typically requires 8 to 12 550W tier-1 panels to achieve a full daytime recharge while powering active daytime loads.

Question 3

What is the difference between LiFePO4 Lithium batteries and Tubular batteries?

Accepted Answer

LiFePO4 (Lithium Iron Phosphate) batteries offer 3,000 to 6,000 charging cycles at 80% Depth of Discharge (DOD)—giving them an 8 to 12-year lifespan. They charge rapidly, require zero acid maintenance, and include a smart Battery Management System (BMS). Tubular lead-acid batteries offer around 1,200 cycles (2 to 3 years lifespan) at a lower initial purchase price, but require periodic electrolyte top-ups. Over a 5-year timeline, Lithium delivers a lower cost per kilowatt-hour stored.

Question 4

Can I connect a lithium battery to any existing solar inverter?

Accepted Answer

Most modern pure sine wave and hybrid inverters with customizable charge voltage settings (such as Growatt, Felicity, Deye, Voltronic, SRNE, and Must) are 100% compatible with LiFePO4 lithium batteries. Older non-configurable inverters may require an external lithium-compatible MPPT charge controller to ensure correct bulk, absorption, and float voltage cutoffs.

Question 5

How does nationwide delivery work across Nigeria?

Accepted Answer

We deliver to all 36 states and the Federal Capital Territory (Abuja). Deliveries within Lagos typically arrive within 24 to 48 hours. Orders to major state capitals (Ibadan, Abuja, Port Harcourt, Kano, Enugu, Benin, etc.) take 2 to 4 business days. Fragile equipment like solar panels and inverters are packed with reinforced corner guards and shock-absorption padding.

Question 6

What payment methods are accepted on BuySolar.ng?

Accepted Answer

We accept secure online debit/credit cards, bank transfers, and USSD via Paystack (Nigeria’s leading PCI-DSS certified payment gateway). We also support direct bank transfer to our verified corporate bank account (UBA: BUYSOLAR NG LIMITED) with automatic invoice generation and order verification.

Question 7

How can I track my order after payment?

Accepted Answer

Question 9

Can I return an item if it arrives defective or damaged?

Accepted Answer

Yes. BuySolar.ng offers a 7-day replacement guarantee. If an item arrives with transit damage or factory malfunction, contact our customer support team within 7 days of delivery. Once verified, we will arrange a replacement or full refund according to our Return & Refund Policy.

Question 10

Does BuySolar.ng provide installation engineers?

Accepted Answer

BuySolar.ng specializes in supplying authentic, verified renewable energy components nationwide. For installation, we partner with a nationwide directory of certified solar technicians and COREN-accredited engineers across Nigeria. Chat with SolarGPT or reach out to our WhatsApp team for an accredited installer referral in your local government area.

Question 11

How often should solar panels and inverters be serviced?

Accepted Answer

Solar panels should be dusted or washed with clean water every 2 to 4 weeks during the dry/harmattan season in Nigeria to prevent dust-induced yield loss. Inverters and battery terminals should be inspected every 6 months to ensure connections remain tight and free of dust or oxidation.
