The best solar installations with backup power offer a sustainable and reliable energy solution for homes and businesses, ensuring uninterrupted power supply while reducing reliance on the grid.

InPower is one of the top home solar companies in Cape Town and offers a wide variety of solar and backup power installations to suit your specific needs but before we go any further we need to understand which type of installation is the best Solar PV system for both solar and backup power.

Types of Solar Installations

There are three main types of solar installations, Grid-tied, Hybrid and off-grid.
Grid-tied systems are connected to the grid, while hybrid systems combine grid connection with battery storage for backup power. Off-grid systems operate independently, relying solely on solar panels and batteries for electricity.

When comparing the average electricity usage for homes and businesses and evaluating industry standard pricing, the best type of solar installation would be a Hybrid system which can be used to offset your electricity consumption from the grid and keep you powered during load shedding.

So, which Hybrid solar PV system is the best? We have 3 recommendations!

The Best 10kW Solar Installation with Battery Backup

InPower’s recommendation: 8kW Sunsynk inverter, 455W JA Solar Panels and two 5.5kW Hubble AM2 Lithium-ion Batteries.

The 8kW Sunsynk inverter is the absolute best inverter for sale in South Africa. It has a high-efficiency rate (meaning no generated solar power is “lost” when converting from DC to AC) and has many additional features including mobile app integration which allows you to monitor your system in real-time from your smartphone!
Most importantly, the 8kW Sunsynk inverter is approved by the City of Cape Town meaning you will be able to sell excess solar power generated by your system back to the grid for cash!
We install only the highest quality solar panels. The JA Solar DeepBlue 4.0X series is the best value-for-money panel in the world. Through the use of a high-performance N-type silicon substrate and the introduction of several other technological improvements, the efficiency of the JA Solar Deep Blue 4.0X series has improved by over 22.4% compared to the previous 3.0 series all while keeping its costs moderately low.

And finally, for many years, The Hubble AM2 has been regarded as the industry's top lithium-ion battery. With a run-time of over 5 hours at 1kW and a recharge time of 2 hours from a 15% charge, the 5.5kW Hubble battery will keep you powered during Stage 8 load shedding and above!

The Best 5kW Solar Installation with Battery Backup

InPower’s recommendation: 5kW Sunsynk inverter, 455W JA Solar Panels and one 5.5kW Hubble AM2 Lithium-ion Battery.

For medium-sized homes, the 5kW Sunsynk inverter is the ideal residential load-shedding solution. The 5kW system won't generate as much power as the 10kW system but this solar installation still adds significant value to your property.

The JA Solar DeepBlue 3.0 series is a great value-for-money panel. The industry-standard S-type silicon substrate guarantees great performance during peak sunlight hours without having a significant impact on your wallet.
Accompanying the state-of-the-art JA solar panels is the Hubble AM2. Regarded as the premium lithium-ion battery on the market for years, the battery has a run-time of over 5 hours at 1kW and a recharge time of 2 hours from a 15% charge. The 5.5kW Hubble battery when connected to the 5kW Sunsynk inverter will be able to power your;  TV, WiFi, lights, DSTV, computer/laptop, cellphone chargers, fan/electric blanket, fridge, kettle, and microwave.

Solar Installation Guidelines

In the realm of solar installations with backup power, it is crucial to adhere to the guidelines set forth by local authorities. The City of Cape Town has released comprehensive Solar guidelines to ensure the safe and efficient installation of solar systems within their jurisdiction. These guidelines cover a variety of topics, including panel placement, system sizing, electrical connections, and building code compliance. By following these guidelines, individuals and businesses can confidently implement solar installations with backup power, contributing to the city's renewable energy goals while maintaining the highest safety standards. The City of Cape Town's guidelines serve as a valuable resource for those seeking to integrate the very best solar installations with backup power, providing a framework to ensure optimal system performance and compliance with local regulations.
Whether you are considering a grid-tied system with battery storage or an off-grid setup, incorporating these guidelines will help you achieve a reliable and sustainable solar installation with backup power capabilities.

Orphan Solar Systems

When discussing the best solar installations with backup power, it's essential to be aware of potential risks and challenges. An important aspect to consider is the issue of orphan solar PV systems. Orphan solar PV systems are installations that have been abandoned or neglected, typically due to poor maintenance or the installer going out of business. These systems can pose safety hazards, energy inefficiency, and financial burdens. To ensure the very best solar installations with backup power, it is crucial to choose reputable installers, perform regular maintenance, and consider long-term support and warranty options.

By being proactive and informed, individuals and businesses can mitigate the risks of orphan solar PV systems and enjoy the benefits of reliable and sustainable solar installations with backup power. Prioritising quality, ongoing support, and accountability are essential to ensuring the best solar installations with backup power that deliver both environmental and economic advantages.
