Frequently Asked Questions
Solar PV Systems
Solar PV (photovoltaic) systems convert sunlight directly into electricity. When sunlight hits the solar panels, it creates an electric field across the layers, causing electricity to flow.
Savings vary depending on your energy consumption and system size, but if done correctly and by following all steps can save you over 100% in summer and over 85% all year.
Standard grid-tied systems will shut off during a power outage for safety reasons. However, systems with battery backup can continue to provide power during outages.
Most solar panels come with a 13 year and 25-year performance warranty and can last even longer. Their efficiency may decrease slightly over time, typically by about 0.5% per year. Efficiency after 25 years still around 88%.
Yes, solar PV systems can work with prepaid meters. You’ll simply buy less electricity as your solar system generates power for your use.
Ecologic Optimise uses AI to manage your energy production and consumption, maximizing self-consumption of solar energy and optimizing battery usage, especially during load shedding periods or when tariffs are different at different times of the day (energy arbitrage).
Yes, the City of Cape Town allows users to be credited for excess electricity fed back into the grid. This is done through a formal application process for the installation of a Small-Scale Embedded Generation System (SSEG). Different municiplaities have different rates but most can feed the grid.
To apply for the feed-in tariff program in Cape Town, you need to submit a formal application for an SSEG installation. This process ensures that your system meets all necessary safety and technical requirements. Our team at Ecologic has a function to apply for this on your behalf and can guide you through this application process.
Heat Pumps
Heat pumps extract heat from the air outside and transfer it to water inside your home. They use a small amount of electricity to move heat rather than generate it, making them highly efficient.
Heat pumps are typically 3-4 times more efficient than traditional electric geysers. Many customers see savings of 60-70% on their water heating costs. Return on investment is usually about 2.5 years
With proper maintenance, heat pumps can last 10-15 years or more.
Modern heat pumps are designed to operate quietly. While they do make some noise, it’s usually no louder than a refrigerator or an airconditioner.
Yes, modern heat pumps can operate efficiently even in cold temperatures. The interesting fact is they save more money in winter as clients use more hot water in winter.
Heat pumps can be powered by your solar PV system, further reducing your reliance on grid electricity and maximizing your energy savings during sunlight hours and off batteries at night.
Solar Pool Heating
Solar pool heating systems pump pool water through a series of solar collectors where it’s warmed by the sun before returning to the pool.
Solar pool heating is most effective during sunny months. In cooler or cloudy periods, you may need to supplement with a heat pump for consistent heating.
Costs vary depending on the pool size, desired temperature, and heating method. Solar heating has very low operating costs, while heat pumps are more efficient than traditional heaters.
The heating time depends on factors like pool size, desired temperature increase, and heating system capacity. Solar heating typically raises pool temperature by 3-5°C over 3-5 days of good weather.
In most cases, yes. We’ll assess your current setup and advise if any upgrades are necessary.
Heated pools extend your swimming season and increase the value of your pool investment. With energy-efficient options like solar and heat pumps, the running costs can be quite reasonable.
