Renewable energy used to be the future, it’s now the present. The energy transition marks the global shift from dependence on fossil fuels to a low/zero carbon future, but what will that involve? Solar power, offshore wind, geothermal, biomass and hydrogen all have their parts to play, backed by government policies and subsidy schemes to incentivise companies. In our blogs we will explore the different elements of this booming global industry, which Brunel is helping to grow by providing companies with specialists and industrial services.

The energy industry is changing, fast. There’s a new and exciting development almost every day, and we are dedicated to keeping you up to date. After all, the better informed you are, the better choices you can make. So keep an eye on this section and be in the know!

Despite solar being a net-zero emission source, there are still reservations about its use, owing to its variable nature. This has led to increased usage of solar trackers for improving the efficiency of systems towards accelerating renewable energy adoption.

Earlier, solar panel efficiency was at 15%. It has now become more than 20%. This increase in efficiency results in the embodied energy being paid for in less than 2 years. This applies to locations with sun exposure for the majority of the year.

The efficiency of solar panels is a direct indicator of their performance. High-efficiency panels employ higher-grade N-type Silicon cells. These cells come with improved temperature coefficients and lower power degradation. Some of the manufacturers offer warranties with 90% or higher retained power output, even with 25 years of use.

Bifacial panels are a perfect example of such high-energy solar panels. They have power output ratings of over 500 watts. Combined with solar trackers they pose the most viable solution to recover the capital costs quickly.

Bifacial panels have been around since the 1960s but the tech didn’t take off as it was too expensive. With reduced raw material costs and improved energy outputs, it is once again gaining traction.
