Solar system for a shop with evening backup power
A solar system for a small retail shop that keeps the lights and the till running through a few hours of evening power cuts. Built around the LONGi Solar 11 × Hi-MO X10 Guardian LR7-60HVHL 550W — LONGi Solar quotes the rest on WhatsApp.
That's a 6 kW inverter, 5.1 kWh of battery storage and 11 panels working together.

How we sized it
This system is built to handle 5.6 kW at once. Appliances like compressors and pumps briefly draw far more than their running power the moment they switch on — so we size for that peak moment, not just the average, which is what keeps the inverter from tripping when a few things start up together. And the 6 kW inverter carries comfortable headroom above that peak.
Day to day, that's about 25.2 kWh of use — the number the LONGi Solar bundle above is built to cover.
We set aside about 4.2 kWh for that window; the smallest right-sized setup gives you 5.1 kWh installed, so the essentials keep running through the cut — LONGi Solar quotes the exact battery for you on WhatsApp.
The array works out to 5.5 kWp — 11 panels of the Hi-MO X10 Guardian LR7-60HVHL 550W across roughly 29 m² of roof — assuming the strong, fairly steady sunshine typical of our main markets (about 5.7 peak sun hours a day). Your own roof may do a little better or worse depending on shading and the season.
Frequently asked questions
What can this system power?
A small retail shop, two ACs and a till running all day. It's sized to handle up to 5.6 kW at once — enough for whichever appliance switches on hardest.
How long does the backup last?
It's sized to set aside about 4.2 kWh for that window — about 4 hours at this home's average rate of use.
How many solar panels does it need?
11 panels, about 5.5 kWp, filling roughly 29 m² of roof.
Can I expand this system later?
Yes — inverters, batteries and panel arrays in this range are modular, so you can add more battery modules or extra panels later, starting from this 5.6 kW / 5.5 kWp baseline.
