The inverter is the heart of a PV system. It’s the crucial interface between your solar panels and the rest of the home, batteries or national grid. Aside from converting DC solar power into usable AC, it houses many of the system’s safety features and performance monitoring.

Given it’s such an important component, let’s talk about how to choose a solar inverter. What do you have to consider, and which is the best model?

The electric car revolution is well underway and many people in the UK are now taking delivery of their Tesla Model 3. But have you considered how you’ll be charging your new vehicle? What’s the best EV charger for Tesla cars?

Another week and another upheaval in the world of solar… While the world wakes up to the imminent threat of climate breakdown, our trusty government has decided it’s the perfect time to hike the VAT on solar PV installations.

In the wake of the largest climate protests the world has ever seen, we have dug a little deeper in our own back yard to assess the ‘life time’ carbon footprint of a solar system...

With the increasing threat of climate change urging many of us to cut back on fossil fuels, solar is ever more appealing. It’s a technology that empowers individuals to supply themselves with clean, renewable energy at an increasingly affordable price. Innovation in this industry is constant, so let’s see how one of the developing trends in PV stacks up by comparing solar tiles vs solar panels.

One of the most appealing aspects of solar PV is that it requires very little maintenance in return for decades of functioning lifetime. With no moving parts, solar panels aren’t put under the mechanical stresses inherent in other generators. But the system is a significant investment - with most of its return based on using its electricity - so a little upkeep is worthwhile to ensure it’s always performing at its best.

Those looking to make the greatest environmental benefit from their roof space may feel they should choose between solar panels and green roofs - but can you combine the two? Yes - though both systems need to be designed properly.

It’s important to do your research when planning your solar system, but the sea of technical terms can soon become overwhelming. Let’s address some of those you may come across when comparing types of solar panel - and see how those types stack up.

Why does the solar panel output matter?

When installing solar panels there are many things to deliberate over, whether that be the price or aesthetics, but probably the most important metric to consider is the output. More often than not the price you pay for an installation will be relative to the power output of the system. The rated power output or wattage of a panel represents the theoretical power output under ideal conditions and is a strong indication of the amount of electricity a panel will generate. However; there are factors other than the panel’s wattage to consider when determining its output or energy generation. 

Why are solar panels blue (usually)?

The standard solar panels that you see most commonly on rooftops are a shimmering blue colour. This is because they are made from polycrystalline silicon - lots of crystals melted together.

But you may have also seen black solar panels - these are monocrystalline. Formed from single silicon crystals, they have a greater efficiency and (in many people’s opinion) a more attractive appearance.
