We often get enquiries from people who already have solar panels installed on their roof, but are keen to increase the amount of renewable energy they can produce. This might be because they had a battery fitted, or maybe their consumption has gone up with a new heat pump or electric car.
So what steps are there to overcome if you want to add more solar panels to your existing system to try and reduce your electricity bills even further?

Since solar panels are static, there’s little to actually, well, see when they’re generating. Sure, it’s nice to start receiving smaller energy bills but, if you’re like most of our customers, you’ll want to dig into the performance data every now and then.
As well as checking when the most solar power is being generated (a useful reminder to turn on the dishwasher and make the most of that free electricity), solar monitoring is great for reviewing past output and comparing performance. Sudden drops can indicate faults that need fixing, or help assess if it’s worth giving the panels a clean.

Some of our clients are surprised to learn that there can be limits on the number of solar panels they can get on their roof, beyond the obvious physical and cost limitations. In fact, for solar PV systems over a certain size, grid permission is needed before installation can go ahead.
In this post, we’ll explore how many solar panels you’re allowed to install without prior permission, and how we can help you determine the maximum possible allowance for your property.
Today we’re going to answer some common questions around sizing solar PV systems, including the conditions that affect ‘clipping’ and achieving the maximum rated output.

The DNO or distribution network operator is the company responsible for distributing electricity from the National Grid to your home or business. In the UK there are 14 different district networks or DNO regions which are owned by six groups. For our installation zone, the distribution network operators which we are concerned by are Scottish & Southern Electricity (SSE), UK Power Networks (UKPN), and Western Power Distribution (WPD).

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?
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.
