1. What does InPower Energy do?

InPower Energy is a Cape Town–based energy management company that designs, installs and finances grid-tied/hybrid (battery backup) solar systems for residential homes and commercial properties. We also offer generator sales, rental and management, as well as smart metering and utility management solutions for businesses.

We are based in Claremont, Cape Town, and primarily serve residential homes, body corporates and commercial businesses across Cape Town and the broader Western Cape. For larger commercial and generator projects, we can often assist clients outside the immediate Cape Town area.

Our residential installations start with an assessment of your roof, energy usage and future needs. We then design a custom system, install solar panels, a hybrid inverter with battery storage, and handle commissioning and compliance on your behalf. After installation, we offer ongoing technical support and performance monitoring.

Most homeowners can significantly reduce their electricity costs by installing a correctly-sized solar system with battery backup. Your exact savings depend on your current consumption, electricity tariff structure, roof orientation and how much electrical usage the Photovoltaic (PV) installation provides during solar hours, but we provide an estimated savings and pay-back analysis before you proceed.

We offer a range of solar and backup packages at different sizes and price points. Typical turnkey residential systems, including panels, inverter, batteries, engineering sign-off and municipal registration, start from a competitive price point and scale up depending on the size and equipment chosen. We provide a detailed quotation tailored to your property and energy needs.

Yes. InPower Energy offers flexible solar finance options for approved customers. Instead of paying a large amount upfront, you pay a fixed monthly instalment over an agreed term. This lets you benefit from backup power and bill savings while spreading out the cost of your system.

Yes. Our solar financing solutions are available for both residential homeowners and commercial clients. For homeowners, we structure repayments around your budget and energy profile. For businesses, we can align finance with available tax incentives and performance-based models to optimise cash flow and return on investment.

A grid-tied solar system uses solar panels, as well as a grid-tied inverter and batteries to generate electricity from the sun. A hybrid inverter system has a hybrid inverter and batteries to store excess solar energy for later use. It also charges from the grid and supplies power during load shedding or power outages. Solar power reduces your grid usage, while inverter-only backup focuses on keeping essential circuits running when the grid fails.

We use reputable, high-quality brands that perform well in South African conditions. This includes well-known inverter brands, reliable lithium-ion batteries and Tier-1 solar panels. Using proven equipment ensures strong warranties, long-term performance and easier support.

Most residential solar and battery systems can be installed within one to three days, depending on system size, roof complexity and weather conditions. Larger or more complex projects, especially on commercial sites, may take longer. We will confirm the expected installation timeline before work starts.

Yes. We handle the full compliance process for you. This includes the necessary engineering sign-offs, electrical Certificates of Compliance and any required small-scale embedded generation (SSEG) registration with the local municipality. This ensures your system is legal, insurable and grid-compliant.

Yes we do. InPower Energy supports you after installation with technical maintenance, troubleshooting and performance monitoring options. Our team can help optimise your system, identify issues early and recommend maintenance or upgrades to keep your system running efficiently.

Solar is an ideal solution for commercial and industrial operations in Cape Town. It can help protect your business from load shedding, reduce day time electricity costs and improve long-term budget certainty. For many businesses, solar combined with smart metering and tariff optimisation delivers strong financial and operational benefits.

Smart electricity metering and tariff management involves detailed measurements and analysis of your energy usage and aligning this with the most cost-effective tariff structures. By understanding how and when your business consumes electricity, we can recommend solutions that reduce peak demand charges, optimise time-of-use rates and lower your overall utility bill.

Yes. InPower Energy offers a full generator solution for commercial clients, body corporates and estates. Services include generator sales, leasing or rental, repair and maintenance, as well as fuel management. Generators can also be integrated into a broader energy strategy that includes solar and battery backup.

We only work with equipment that has strong manufacturer warranties on inverters, batteries and solar panels, and we back this up with professional workmanship guarantees on all of our installations. Our installers work to strict compliance standards, giving you peace of mind that your system is safe, reliable and protected over the long term.

It is possible to design an off-grid or near-off-grid solution, but most homeowners and businesses choose a hybrid system that combines solar, batteries and a grid connection. This approach balances reliability, cost and flexibility. Our team can model different scenarios and advise on the best level of grid independence for your needs and budget.

InPower Energy offers a full end-to-end energy management service backed by many years of experience and hundreds of successful installations. We don’t just sell solar panels. We engineer complete solutions that can include solar, batteries, generators, smart metering and utility management, providing one trusted partner for all your energy needs.

For suitable commercial projects, we can structure a shared savings or performance-based model. This typically means we invest in or co-fund the solar system and you pay for the energy at a rate that is usually lower than your current tariff. The resulting savings are shared according to the agreement, aligning our incentives with your long-term cost reduction.

You can request a quote by contacting our team via phone or email, or by completing the contact form on our website. We will need some basic information before we can prepare a tailored proposal for you. This includes your location, recent electricity bills, roof or site details and your main goals (do you want to save more money, have backup power, or both?)
