Frequently Asked Questions
Everything you need to know before going solar with YST Energy.
Getting Started
How do I know which package is right for my business?+
Use our free recommender tool on the homepage — tell us how many ACs, lights, freezers, and other appliances you run, plus how many backup hours you need, and we'll instantly match you to the right system. You can also chat with our team directly on WhatsApp for a more detailed assessment.
Do you offer a free site visit?+
Yes. Every quote request includes a free site assessment where our technical team evaluates your roof space, current electrical setup, and power consumption before confirming your final system size and price.
How long does installation take?+
Most residential and small business systems are installed within 48–72 hours of site assessment. Larger industrial systems (Industrial, Enterprise, and Titan packages) may take 1–2 weeks depending on scale, panel quantity, and site readiness.
Pricing & Payment
What payment plans do you offer?+
Four options: full Outright payment, our 80/20 Flex Plan (pay 80% now, balance in 30 days), Sterling Bank financing (10% equity, up to 36 months), and Alternative Bank financing (20% equity, 6–24 months).
Is there a difference in price between payment plans?+
The base system price is the same. Bank-financed plans include interest and processing fees specific to each bank's terms, which is reflected in the total cost shown on each package's payment table. Outright payment is always the lowest total cost.
What bonuses do I get with a bigger order?+
Orders from ₦15m and above on Outright/Flex plans receive a free 1.5HP inverter AC. Orders from ₦25m+ receive 2 inverter ACs plus a free promotional video. Orders from ₦50m+ receive 2 ACs, a free promo video, and a free professional website. Bank-financed plans qualify for bonuses starting from ₦30m.
Do I need a guarantor for bank financing?+
Requirements vary by bank and loan amount. Our team will guide you through the exact documentation needed for Sterling Bank or Alternative Bank financing during your application.
The System Itself
What's included in every package?+
Every package includes solar panels, a hybrid inverter, lithium battery storage, all necessary cables and mounting accessories, full installation labor, and logistics/delivery to your site — plus a 5–10 year warranty.
What happens on a cloudy or rainy day?+
Your battery still provides backup power even without sun — we publish honest "battery only" runtime estimates for exactly this scenario on every package page, so you know what to expect on the worst days, not just the best ones.
Can I upgrade my system later if my business grows?+
In many cases yes — additional panels or battery capacity can be added to an existing system. Talk to our technical team about your specific setup before purchasing if you anticipate growth.
Warranty & Support
What does the warranty cover?+
Our systems carry a 5–10 year warranty covering manufacturing defects on solar panels, inverters, and batteries, plus installation workmanship. See our full
Warranty page for component-specific terms.
What if something goes wrong after installation?+
Contact our team via WhatsApp or phone. Warranty-covered defects are repaired or replaced at no cost. For general maintenance outside warranty terms, we offer scheduled service visits.
