Fundamentals

Discover the truth about residential solar systems. Learn how they integrate with your home, their performance in various conditions, and their long-term environmental benefits. Solar energy has recently become a hot topic in home improvement and money savings. However, many homeowners still harbour misconceptions about this technology based on outdated information or outright myths. As solar […]

You’ve decided to go solar. You understand panels generate energy from sunlight—but what about the mysterious ‘inverter’? Most homeowners don’t realise it’s actually the brain of your solar system, and choosing the wrong one can mean higher bills and wasted savings. The solar inverter is the conductor of your solar energy system, orchestrating the flow […]

Solar panels produce electricity by converting sunlight into direct current (DC). How do they work, what components are involved, and what are the considerations when connecting and placing them? In this article, we’ll delve into these questions. We’ll discuss the workings of solar panels, their high-level components, and some practical aspects of working with them. How do […]

• Adding a battery more than doubled annual savings in MCS data — from £380 with solar alone to £840 with solar and storage, because stored energy is 5-7x more valuable than exported energy.
• DC batteries cost less per kWh than AC batteries because they do not include a built-in inverter — but you need a hybrid inverter anyway for solar, so the total system cost is lower.
• C-rate determines whether your battery can keep up with peak loads: a 0.5C battery on 5 kWh only delivers 2.5 kW, which will not run an oven and washing machine together.
• LiFePO4 batteries last 3,000 to 6,000+ cycles — at one cycle per day, that is 8 to 16 years of daily use before capacity degrades meaningfully.
• Battery prices have dropped 85% since 2010. For most UK homes on single-phase, a 48V LiFePO4 battery paired with a hybrid inverter is the practical, cost-effective choice.

• Hybrid inverters serve as central nerve panels, seamlessly orchestrating DC solar generation alongside battery storage charging and intelligent grid export.
• Microinverters shine on complex, shaded roofs by optimizing each solar panel individually, though they come at a significant premium and add potential points of failure on the roof.
• String inverters remain the most wallet-friendly and robust solution for large, unshaded arrays where battery storage isn’t an immediate requirement.
• DNO limits matter: Before choosing a high-capacity 5kW or 8kW inverter, ensure you’ve reviewed the local UK DNO restrictions under G98 / G99 regulations.
