As more people embrace renewable energy, solar power has become the go-to solution for both homes and businesses. But here’s the truth most installers won’t tell you:
Jumping into a solar installation without proper solar sizing is like building a house without a foundation. You’ll either overspend, underpower your home, or worse — shorten the lifespan of your investment.
This is where the Globisun solar system sizing app comes in — a powerful, easy-to-use tool designed to take the guesswork out of knowing your solar needs.
Let’s take a true-to-life example.
Mr. Ade, a boutique owner in Ibadan, Nigeria, decided to install a solar system after months of battling fuel scarcity and generator noise. Without proper calculations, his installer suggested a 3kVA inverter with two 200Ah batteries and six 300W solar panels.
At first, it worked fine — until he plugged in his pressing iron, fan, lights, and freezer during business hours. The batteries drained too quickly, and within a month, one was damaged.
He had no idea his actual energy demand exceeded the system’s capacity.
Had Mr. Ade used the Globisun solar system sizing app, he would have simply:
Entered all his appliances (e.g., 1 freezer, 2 fans, 1 pressing iron, lighting, POS, etc.)
Selected their daily usage hours
Received a detailed breakdown of his total energy demand and the recommended system configuration
Instead of spending ₦1.2M and getting an inadequate setup, he would have: ✅ Sized his system properly
✅ Avoided damage to his batteries
✅ Saved money in the long term
✅ Had a solution tailored to his actual business needs
Solar sizing is the process of determining:
The total energy consumption (in watt-hours per day)
The appropriate battery storage
The number of solar panels required
The right size of inverter and charge controller
Without accurate sizing, your system may fail when you need it the most. That’s why solar sizing should always be the first step in every solar installation project — whether it's for a small apartment, office, or rural clinic.
The Globisun solar system sizing app is built for both beginners and professionals.
Key features include:
Easy load input (TV, fans, freezers, boreholes, CCTV, etc.)
Instant calculation of total daily energy consumption
Suggested solar panel capacity
Battery bank size recommendation (12V, 24V, or 48V systems)
Proper inverter rating
Appropriate charge controller size
Global access to solar vendors who sell matching products
Within minutes, you’ll have a professional-level report that shows exactly what your solar system should look like — even before you meet an installer.
Globisun is not just for end users.
Solar vendors can:
Sign up to showcase their solar products

Homeowners tired of unreliable grid power
Businesses that want uninterrupted operations
Solar installers who want a credible sizing tool
Rural communities planning micro-grid setups

Just like you wouldn't build a house without a plan, don’t install solar without knowing your actual needs.
