The electric vehicle boom is imminent. The government recently pledged £400m investment towards EV charging infrastructure as part of its commitment to net zero by 2050. Emission-free number plates are set to turn green to boost driver benefits, awareness and uptake.
In a perfect world, UK roofs would all face south, with a 35° pitch and no shading in sight. But we don’t live in a perfect world. As solar installers, we have to find clever ways to maximise the potential power from roofs of all make ups, orientations and shaded spots.
This is best achieved by using micro-inverters or power optimisers - nifty bits of kit, collectively known as Module-Level Power Electronics (MLPEs). As that name implies, these bring a degree of power optimisation at the module level (i.e. at the level of each individual solar panel). This means you can get the most from panels under different levels of sunlight (facing varying directions or affected by shading, dirt etc).
But which is the best solution? Let’s focus on our favourite brand of power optimiser, and compare SolarEdge vs micro-inverters.

While solar panels are traditionally retrofitted to an existing rooftop, it’s becoming more common (especially in newbuilds) to integrate the panels into the roof itself. With in roof PV, you end up with a sleeker, more attractive result.
What is a PERC cell?
PERC solar cells are a variation on the traditional cells used in solar panels that offer enhanced efficiency. The acronym PERC stands for Passivated Emitter and Rear Contact or Passivated Emitter and Rear Cell. Over the last few years they have become more and more popular, to the point where they now make up over 40% of the solar technology market and are expected to dominate by 2021, according to the ITRPV.
