When you invest in solar panels and battery storage, the questions are always the same. How much electricity will it actually generate. How much difference does the battery make. Is there any maintenance or hassle involved. And above all, how much impact will it really have on your electricity bill. Is it a worthwhile investment.

If you want a quick, reliable answer, there are four ways to size a roof for solar: satellite measuring, measuring from architectural plans, measuring in person, and drone survey. Below we go into detail about each method to answer the question how many solar panels you can fit on your roof. Read this blog if you want more than a rough guess.

With solar installations on the rise, many homeowners ask the same question: should I use my solar panels to charge my EV? At first glance, the answer seems obvious. Solar provides free electricity, so why not use it to power your car and enjoy zero-emission miles?

As more homeowners look for sleek, high-performing renewable energy systems, Viridian Solar has emerged as a leading choice for in-roof solar. Unlike traditional on-roof solar systems that sit above the tiles, Viridian integrates directly into the roofline, creating a neat, efficient, and cost-effective solution.

Deciding to install solar panels and a battery is one of the smartest investments you can make for your home. Done right, it can cut energy bills, provide independence from the grid, and add value to your property. But if it’s done wrong, the outcome can be costly and disappointing. Solar is not something you can just order online and have working out of the box. Careful planning and expert design are essential to getting the best long-term return.

Introducing Solar Skin: Custom Solar Panel Aesthetics Without Compromising Performance

A new product is set to enter the UK solar market: Solar Skin. Developed by US-based Sistine Solar, this innovative technology allows solar panels to be customised with designs that either blend into the surrounding roofscape or provide a visually striking alternative to the traditional black or blue panel appearance.

We’ve been eagerly awaiting the arrival of the AIKO Neostar 3 in the UK—and it’s finally here. Now available to order, this panel is already our new standard offering at Spirit Energy. But what makes it so special? Is it really a leap forward from the Neostar 2? And is this the right panel for your roof?

In this post, we’ll take a deep dive into the performance specs, design choices and technology that make the Neostar 3 one of the most advanced residential solar panels currently available in the UK.

Choosing the right time-of-use tariff can transform a solar-and-battery setup from a novelty into a genuine money-saving powerhouse. An energy tariff determines how much you pay for every unit of electricity you import, and what you receive for every kilowatt-hour you export. While most standard plans charge a flat rate, Octopus Energy’s smart tariffs use time-of-use pricing to reward off-peak consumption and peak exports, perfect for households with solar panels, home batteries, EVs or even heat pumps. Though rates vary regionally (London tends to be about 10 % higher than Yorkshire), the principles we explore here apply across the UK.
