Solar Power Solutions Designed for
Performance & Precision
From design to installation, MRC Energy delivers fully engineered solar systems built for performance and tailored to your unique power needs, and engineered for lasting reliability.
Understanding Solar Systems
At MRC Energy, we don’t believe in one-size-fits-all solar. Every installation is designed around your property, your energy profile, and your long-term return on investment.
Our team combines electrical engineering expertise with compliance-backed design to ensure your system performs safely, efficiently, and in line with national standards.

Why it matters: Designed correctly, PV + inverter can cut daytime consumption and protect you from tariff hikes. Add batteries for backup and night-time use.
1. Panels (PV)
Sunlight hits PV cells → electricity is produced asDC.
2. Inverter
The inverter convertsDCintoAC— the type your property uses.
3. AC Power
Power feeds your main AC panel. Extra can supply loads and reduce grid use.
Grid-Tied Solar Systems
MRC Energy’s Grid-Tied Solar Systems are engineered for performance, precision, and savings.These systems generate clean electricity during the day, using solar energy firstand drawing from the grid only when additional power is required.
Designed for both single-phase and three-phase properties,this configuration balances independence and reliability, cutting monthly costs and reducing dependence on Eskom while maintaining a consistent supply.
Before installation, MRC Energy conducts a detailed electrical and energy audit to assess your load profile,efficiency opportunities, and solar capacity. Each system is custom-designed to your roof orientation, sunlight exposure, and consumption patterns for maximum ROI and long-term reliability.
Grid-tied Solar System Flow:PV panels→Inverter→AC disconnect→Main service panel→Property load→Optional feed-in to grid.
Did you know?
In approved South African municipalities, surplus energy from your MRC grid-tied system can be fed back into the local grid, allowing you to earn credits or offset your energy use, depending on local feed-in tariff policies.
(Subject to SSEG approval, compliant metering, and municipal regulations.)
Key Features
- Savings on electricity consumption — use solar power first before drawing from the grid.
- Renewable energy source — clean and sustainable power generation.
- Low maintenance — reliable, long-lasting components with minimal upkeep.
- Modular & scalable system — can be expanded over time as energy needs grow.
- Feed-in ready — sell excess energy back to the grid where local policies allow.
- Environmentally friendly — reduces carbon footprint and reliance on fossil fuels.
Off-Grid Backup Solar Systems
At MRC Energy, we design and install off-grid solar systems with battery backup — ideal for properties across South Africa that want maximum independence and long-term reliability. Your MRC system harnesses the full benefit of solar energy so essential circuits can run without relying on the grid.
Every project starts with a detailed energy audit and load assessment to understand your daily usage and peak demand. We then design on the 1 kWp (kilowatt-peak) method, optimising for location, roof orientation/tilt, shading and expected consumption.
The final system size (PV array, inverter capacity, and battery storage) depends on:
- Regional solar conditions and seasonality
- Available roof area and orientation
- Your load profile and peak-demand periods
Design Matters
We size your system to match essential loads and manage peak demand for a smooth load profile, higher efficiency, and longer battery lifespan.
Battery Management
We use advanced chemistries like LiFePO₄, sized precisely for your depth of discharge (DoD), cycle life, and autonomy hours — with charge and temperature control to ensure reliability and lifespan.
Generator Integration
We include an optional generator as part of your off-grid design — configured to automatically recharge your battery bank during prolonged cloudy or rainy periods, keeping your system online 24/7.
Off-Grid Solar System Flow:PV panels→Charge controller→Battery bank→Inverter→AC Panel & Essential loads→Optional generator for extended autonomy.
Key Features
- No reliance on Eskom — powers essential and critical loads independently.
- Free, renewable energy over time with correctly sized PV modules.
- Modular & scalable design — expand panels and batteries as needs grow.
- Optimised battery chemistry and autonomy sizing for 24-hour uptime.
- Optional generator integration for extended cloudy-day reliability.
- Professionally engineered with compliance, safety, and long-term performance in mind.
Solar Audits & Design Integrity
Before any installation, we conduct a full solar audit and electrical readiness check.
This ensures:
- ✔
Your property meets safety and load requirements - ✔
System design is compliant with SANS and ISO standards - ✔
Energy yield and efficiency are maximised for your location and usage pattern
Because at MRC Energy, our goal isn’t just installation — it’s long-term performance.
