Technical FAQs 4

What is solar retrofit?

Solar retrofit is the process of upgrading existing solar energy systems to improve their efficiency, functionality, or capacity. This can involve modifications such as adding new solar panels, power optimisers or inverters to meet increased energy demands or enhance system performance.

What are the main objectives of solar energy retrofitting design?

The main conclusions are as follows: Carbon emission is the primary objective of the retrofitting design for the existing residential building rooftops by using solar photovoltaic panels and thermal collectors, of which the weight of the carbon emission based on the entropy value method is 42.68%, while that for the cost benefit is 57.32%.

Should you retrofit a solar energy system?

Let’s say you’ve owned a solar energy system for several years, and over time, your energy needs have expanded. Whether you need more power to charge a new electric vehicle or because of increased home consumption (maybe you invested in a new heat pump), there are many reasons why people may want to retrofit an existing solar energy system.
