How Governor’s purchases encouraged 5 UNN students building solar energy inverters
Five students of the University of Nigeria Nsukka (UNN) have disclosed how they were encouraged to continue building solar energy inverters, in spite all odds.
With 75 planning applications; 39 trained professionals and two offices, Business Manager, Nwangele Godwin Chukwuemeka; Quality Control officer, Okereke Kingsley; Production officer, Esumeh Aaron; Field Operations officer, Udeh Isaac Nnaemeka and Product Logistics officer, Ogechukwu Uchechukwu Emmanuel, have already completed 38 projects.
The Students shared how Enugu State Governor, RT. Hon. Ifeanyi Ugwuanyi’s patronage at recent Enugu International Trade Fair enabled them to have some resources to invest on the project locally developed.
Read their inspiring story as represented by Ogechukwu Uchechukwu Emmanuel.
How was the idea conceived?
It all started with some boys who had big dreams of making solar energy available for people to use at home since it is already in existence in overseas. We started looking for knowledge, ideas and how to make it come by. Thanks to Industrial training and Engineer Precious Chijioke. He blessed us with knowledge during our industrial training.
Five of us: three in Electrical Engineering class, one Electrical Electronics and one Geography Students; found a need for this project. Four of us are finals and one penultimate when we started.
How long did it take from ideation, R&D to real construction and sales?
It took us like seven months to complete the circle and have a finished product. Remember, we are students, so we are putting to test the knowledge we have gathered from classes and personal studies.
You guys must have conducted some research on electricity challenges in Nigeria, can you share with us some of the findings?
The truth is that energy is not cheap anywhere but one peculiar thing with Nigeria is that our people waste energy that they can’t even pay for. An example is, most poor homes use 200watts bulb everywhere while such energy consumption is equal to some fridges used by rich men. Also, the pressure on the national grid by home deprives the industries of this energy, so we thought if homes could key into green energy and leave out the noise and air polluting generators, the industries may gain little life. Another one is that some homes use our grid light to cook instead of using gas as the white men do. You can add yours too.
Where was the idea incubated?
It all started at social science quadrangle, in UNN. When we decided to do what the whites do and have a product no matter what stress and energy it will take.
When do you intend moving to mass production?
We have already started with 20 sets of 2.5kva and 1.5kva.
How much funding are you looking at?
We need about N100 million to flood the market with these products.
You said everything was developed in Nsukka, can you expatiate on that?
We designed our circuit board, more like the thing people call mother board, although we print it in China currently. We make our transformers ourselves here, get iron pan and bend it to our desired shape in Enugu. We then do other things ourselves except painting which we outsource.
How are you sourcing the raw material?
All the things we need are in the local market here. Although we now import resistors, inductors and micro processors via an agent in Ali express which makes them cheap.
What have been the greatest challenges?
At first, it was fund, next was people’s doubt on what we do. Now, it is expansion.
What can you guys take in exchange for this project?
We can take the project for itself. It is now our life.
What are the limitations of the products? Benefits too?
For now, we can boast of systems that are hybrid (uses both solar and disco grid) with in built automatic transfer switch, has load detection sensor as well as LCD for the user. It has a short-circuit detection mechanism inside for stubborn users like Nigerians with automatic shut down both in overload and short-circuit. For battery life extension, it has four stage charge modes with trickle charge effect. It is one of the best power machines anybody in Nigeria can use because we understand the Nigerian user more than any foreign company. With respect to the limitations, we believe that our designs are not as beautiful as we want it to be but we will soon get over that.
How affordable are the products compared to imported ones?
We have the competitive power here, because our product is very affordable compared to any foreign system of same specification. Our prices are approximately 40% less than any one in the market.
Have you received any grant?
No, but will be happy to get
Patented?
We have submitted documents for patency, but this is technology, only those with spiritual eyes can imitate it.
How did you raise the initial funding?
We started with N45,000 and were adding N5,000 each until we got things set. As I said early, it was like seven months. And then one day at a trade fair, Gov. Ugwuanyi Ifeanyi of Enugu state bought our product alongside Mr. John Busco. That was our first return. We reinvested all. And we kept saving and adding, hunger was on all our faces, but we kept smiling. One thing I must add, all our friends showed us love even when our first test system blew up. They still clapped for us.
What are the sizes and functionality?
Yes it is in sizes, from 1500 watts to 20,000 watts. You use it like other imported system. We have a manual too. It serves as a replacement for your generators and some decide to remove their disco grid entirely because it is reliable. You keep solar panels outside which traps sun rays as ultraviolet and sends it to your batteries as DC current. This DC is sapped by the inverter and sent out as AC for your home use.

With Black Friday and Cyber Monday around the corner, we’re entering a high-risk period for cybersecurity.
A recent Sophos report highlights that malicious emails were the second most common root cause of ransomware attacks in critical sectors, responsible for 25% of cases.
During peak shopping days, this threat intensifies.
Here’s what happens: with the surge in online deals, more employees may be shopping from their work computers, feeling that Cyber Monday is a legitimate time to do so.
This increases the risk of them clicking more freely and potentially exposing the organization to malicious links or phishing attacks.
To keep your organization safe, encourage your team to follow these simple tips:
• Use an ad blocker – Advertisements are not only tracking your every movement and collecting enough information on your habits to make the FBI blush, but they are also a major source of malicious links and deceptive content on the internet. Not only is your browsing safer, but also faster and uses less bandwidth. Two of our favorites are uBlock Origin and Ghostery.
• Use private browsing or incognito mode – To prevent your shopping habits and interests from following you around from site to site (and potentially revealing what gifts you might be purchasing to others using your device, bonus!), you should enable private browsing (Firefox) or incognito mode (Chrome). This will block tracking cookies and help the internet forget your travels as the waves wash away your footprints in the sand.
• Make your browser “privacy smart” – The Electronic Frontier Foundation (EFF) provides a browser extension called Privacy Badger designed to automatically make all the right choices around browsing whilst maintaining our privacy and blocking invisible trackers.
• Avoid using one account on multiple services – When logging into an e-commerce site it is often tempting to use the “Sign in with Facebook” or “Sign in with Google” button. While it takes a few more minutes to create a new login, it will provide more privacy as you are not sharing all of the sites you shop at with these tech giants.
• Use guest login when available – In addition to letting you use an account from other websites, many have an option to use a guest login rather than creating a new account. This is a great option if you don’t expect to need technical support or to do business on a recurring basis. Fewer passwords, fewer personal details, fewer problems if they get hacked.
• Don’t save card details – Many e-commerce sites will default to storing your credit card information in your profile for your “convenience” (or their hope you’ll shop there again). They can’t lose what they don’t have, so tell them not to store your credit card unless it is absolutely necessary.
• Use temporary card numbers – Many financial institutions now offer temporary or one-time use credit card numbers. You can open the app on your phone or in your browser and get a single-use disposable credit card number preventing card fraud and tracking when merchants share card processors. Sometimes you’re even able to specify a card limit per temporary number to further protect your account.
• Use credit, not debit – All of us need to be wary of overspending during the holidays, but it is best to leave the debit card at home. Credit cards offer significantly more protection against online fraud, and you are in the power position in a dispute. You can simply not pay your bill while disputing the charge, rather than having criminals directly drain your bank account of your hard-earned cash.
• Beware of direct messages via social media/chat apps – With modern generative AI technology it is almost trivial to create an entire fake online store and lure people to share their personal information and payment data with you. It’s safest to shop at established sites or those personally recommended to you by friends and family. Many unsolicited messages lead to data collection or theft.
• Don’t click deals in email that look too good to be true or are from businesses you don’t have accounts from – these could be phishing emails hoping to bait you into clicking links to bogus, malicious web sites.
This season, small steps can make a big difference in protecting against cyber threats.

It’s Cybersecurity Awareness Month and Sophos has Some Tips for You!
In the mood of Cybersecurity Awareness Month, Christopher Budd, Director Sophos X-Ops, has compiled some tips for staying secure online.
Cybersecurity Pro Tips:
- Face Scans and Fingerprints are Safer Than Passcodes: Use features like Face ID or fingerprint scans for your devices as much as possible. These are safer than passcodes and devices have good built-in protections for this sensitive information.
- Use Multi-Factor Authentication: Use multi-factor authentication (MFA) whenever possible. This gives an important extra layer of security that makes it harder for cybercriminals to access your accounts. If you can’t use something more secure like secure authenticator applications or physical hardware security keys, use your phone number — it’s safer than using nothing. If you use MFA for only one thing, use it for your email: that’s what attackers want the most.
- Think Before You Share Publicly: Think twice before sharing any information publicly –cybercriminals can use it to access your accounts or to convince someone that they’re you.
- Think about those cute surveys on Facebook with questions about your first car, city you were born in: these are the same kinds of info cybercriminals can use to pretend they’re you and log into and take over your accounts.
- You Don’t Always Need (to keep) the App: Don’t feel pressured to download an app every time: you can often use the service’s website just as well. Apps collect much more data than websites, including your location, your contact list and other info you might not want to share.If you do download an app, think about deleting it when you’re done using it: you can always reinstall it next time you need it.
- Apps from app stores and websites that aren’t the official big names ones like Google Play, Apple’s App Store, Samsung’s Galaxy Store can be very risky. The official stores have security and privacy standards that can identify malicious activity. Always stick to official sources for downloading apps or, if they’re not on the official app stores, download the app from the developer’s official website or use the app’s web version.
- Be On Your Guard for Unexpected Emails and Text Messages: Phishing continues to be one of the most effective tactics cybercriminals use to compromise consumers. If you get an unexpected email or text message, ignore it or at least don’t interact with it (don’t open attachments, don’t click on links). If you think it might be legitimate, reach out directly to who you think sent it and check with them.
- Question Urgency in Emails and Calls: Cybercriminals use urgency to get you to let your guard down and make bad decisions. If someone contacts you saying they’re from a trusted organization like the IRS, police or your bank and need you to take action quickly or something bad will happen, stop and question it. Go to the trusted source like the number on the back of your credit card to independently validate the request.
- Practice Good Password Security: Every account should have its own unique complex password. A strong password is at least 12 characters long with a mix of numbers, upper- and lower-case letters, and punctuation characters. Passwords should not be based on any personal information, and the best ones use a phrase rather than single words. If these passwords are too tough to juggle, try a password manager to stay organized.
- Keep Everything Updated and Run Security Tools. Make sure all your apps and devices are always fully updated. Be sure to have some sort of security software on all of your phones and computers (even if you have a Mac).
- Get Rid of End-of-Life Devices and Software: Everything from operating systems to services to Wi-Fi routers “go stale” and must be replaced eventually. For example, it might surprise you, but your internet router is typically only supported with patches and updates for a few years after you get it. Attackers love out-of-date devices. When something is “out of support” it’s stale: get rid of it and replace it with something fresh.
- Back Up Your Data: While ransomware groups are mostly after businesses that can pay higher ransoms, they still go after people at home. It’s still important to have your data backed up so that you don’t have to consider paying a ransom.
Put Your Mind at Ease Regarding These Cybersecurity Concerns
Part of staying secure requires being able to filter out the noise and prioritize the security actions that matter. Here are things notto worry about. Focus your energy on real risks, not exaggerated threats.
- Public Wi-Fi is Safer Than You Think: Contrary to outdated advice, public Wi-Fi is generally safe due to encryption used by most websites and apps. Use it freely at airports or coffee shops, but avoid sensitive activities.
- Beware of Fearmongering Around New Tech Features: Not every new technology is as risky as it’s made out to be. For example, Apple’s NameDrop feature is generally safe and requires specific conditions to function. However, if you’re concerned, you can easily turn it off in settings.
Stop Stressing Over Public Chargers: The risk of “juice jacking” (data theft from public chargers) is extremely low. Don’t worry about using public phone chargers — just focus on real, more prevalent threats.
