10 Things to Check Before Paying for a Solar System in Zimbabwe
With rising electricity tariffs and unpredictable ZESA load shedding, thousands of Zimbabweans are turning to solar power systems for homes, farms, and businesses. While the solar boom has brought relief, it has also opened the door to counterfeit solar panels, fake lithium batteries, cloned inverters, and unqualified installers. A solar system is not a quick purchase — it is a long-term 20 to 30-year investment that should deliver reliable power, safety, and savings for decades. Choosing the wrong installer or low-quality components can lead to system failure, fire risks, lost warranties, and expensive replacements.

| Top 10 Things to Consider Before Hiring a Solar Company in Zimbabwe |
In Zimbabwe, many buyers fall into the trap of “cheap is expensive.” Flashy online adverts, street-corner deals, and so-called “full solar kits” often come with no after-sales support, no genuine warranties, and no accountability. Once something goes wrong, the seller disappears. This Solar Buyer’s Guide for Zimbabwe was created to protect you. We have compiled a practical checklist to help you verify your installer and confirm that your equipment comes from trusted, proven brands such as MUST Inverters, Evolt Lithium Batteries, SVolt Batteries, Dyness, Felicity Solar, JA Solar Panels, Canadian Solar, Longi Solar, and Jinko Solar.
Understanding brand authenticity, serial numbers, and local warranty support is just as important as system sizing and price. Even premium brands can fail if installed incorrectly or sourced through unofficial channels.
Phase 1: Vetting The Company
Are they legitimate or fly-by-night?
Never hire a "briefcase company." In Zimbabwe, many installers operate solely out of a truck or a WhatsApp group. If your inverter fails in 6 months, you need a physical door to knock on.
The Test: Ask to visit their showroom or office. If they insist on meeting only at your house or a public place, walk away. A reputable company has stock, staff, and a fixed location (e.g., in Msasa, Graniteside, or CBD).
Solar installation is electrical engineering, not just plugging in wires. You need a team that has faced different roof types (tile, chromadeck, asbestos) and load scenarios.
The Test: Ask for photos of their last 3 installations. Look for neat cabling (trunking), labeled distribution boxes, and earthed panels. Messy wires usually indicate a lack of training.
Avoid companies that quote you a price without asking what you want to power. A 5kVA system might run a fridge and lights, but if you have a borehole pump and a booster pump, it might trip.
The Test: A good company will ask for a "Load List" (e.g., What is the horsepower of your pump? Do you use an element stove?). If they don't ask, they are guessing.
Phase 2: The Equipment
Avoid fakes and old technology
Not all panels are equal. Zimbabwe has seen an influx of "sticker-swapped" panels where low-wattage panels are labeled as high-wattage.
The Test: Insist on Tier 1 Brands such as Jinko, JA Solar, Longi, or Canadian Solar. These brands have 25-year performance warranties. Ask to see the datasheet.
Stop buying Gel batteries for main home systems. While cheaper upfront, Gel/Lead Acid batteries degrade quickly if drained below 50%. In a heavy load shedding environment (Stage 3/4), they may die within a year.
The Recommendation: Invest in Lithium-Ion (LiFePO4) batteries (e.g., Pylontech, Hubble, Shoto). They can be drained to 80-90% and last 10+ years (6000 cycles).
Are you getting an "Off-Grid" or a "Hybrid" inverter? A Hybrid Inverter (like Sunsynk, Deye, or Growatt) can blend power sources. It can use solar to power the house and only pull from ZESA if the solar isn't enough.
Why it matters: Old off-grid inverters switch entirely to ZESA when the battery is low, wasting available sunlight. Hybrids save you more money on prepaid tokens.
Phase 3: Safety & Protection
Don't burn down your house
This is where "cheap" installers cut costs. A solar system must have a protection box containing:
- AVS (Automatic Voltage Switcher): To protect the inverter when ZESA comes back with a high voltage surge.
- DC Breakers/Fuses: Between panels and inverter to prevent fire.
- Surge Protection Devices (SPD): To protect against lightning strikes.
The Rule: No protection kit = No deal.
You should never have to manually unplug things when power goes out. The system should integrate into your Distribution Board (DB). Furthermore, the installer must separate "Essential Loads" (Lights, Wi-Fi) from "Non-Essential Loads" (Geysers, Stoves).
The Test: Ask the installer how they handle the electric geyser. If they say "we just put everything on the inverter," they are setting you up for a battery failure.
Phase 4: The Deal
Warranties & Support
A "5-year warranty" means nothing if the company tells you "we have to ship it back to China and wait 3 months."
The Test: Ask if the warranty is local replacement or repair. Reputable Zimbabwean distributors will swap out a faulty unit or repair it in Harare/Bulawayo within a few days.
Solar systems need monitoring. Modern systems have Wi-Fi dongles that allow you (and the installer) to monitor performance via an App.
The Test: Ask if they set up the Wi-Fi monitoring for you. Also, ask for references regarding their response time. If the system trips on a Friday night, will they answer the phone?
