Question 1

How much can I actually save on my energy bills with solar?

Accepted Answer

It’s the question on everyone’s mind, and for good reason! When you invest in solar, you aren't just putting panels on a roof; you’re essentially building your own mini-power station. While the exact "pounds and pence" figure varies from home to home, most of our customers in Derby and across the East Midlands see a massive reduction in their monthly outgoings.

Generally speaking, a well-designed solar PV system can reduce your electricity bills by anywhere from 50% to 70%. How do we get to those numbers? It usually comes down to three main factors:

Direct Consumption: This is the "free" energy you use the moment the sun is shining. Instead of buying electricity from the grid at standard rates, your appliances run directly off your panels.

Battery Storage: This is the real game-changer. Without a battery, any solar energy you don't use during the day is sent back to the grid. With a battery, we can store that power so you can use it to cook dinner or watch TV in the evening. This dramatically increases your self-sufficiency.

Smart Export Guarantee (SEG): For any excess energy you do send back to the grid, your energy supplier will actually pay you! It’s a great way to squeeze even more value out of your system.

Because we are brand-agnostic, we don't push one specific manufacturer. Whether it’s a high-efficiency premium panel or a robust budget-friendly system, we tailor the setup to your specific roof orientation and energy habits. We want to make sure the math works for you before a single bolt is tightened.

To give you total peace of mind while you're watching those savings roll in, we provide a 10-year workmanship guarantee on all our solar installations. We’ve been serving the local area (within a 40-mile radius of Derby) for years, so you can trust that we’ll be here to support you long after the installation is complete.

Question 2

Why do you need a copy of my electricity bill and a screenshot of my property?

Accepted Answer

It might feel like we’re being a bit nosey, but we promise there’s a very good method to our madness! 🕵️‍♂️ When we ask for a recent electricity bill, it’s not because we’re interested in your spending habits—it’s actually the "secret sauce" for designing a system that actually saves you money. Think of it like a tailor measuring you for a bespoke suit; we need to know exactly how much energy your home "wears" throughout the year. By looking at your annual kilowatt-hour (kWh) usage, we can calculate the perfect number of solar panels and the right size of battery storage to ensure you aren't overspending on kit you don't need, or worse, running out of stored sunshine by 7:00 PM! ⚡🌙

As for the screenshot or photo of your property, this helps our design team perform a "virtual site survey." We use high-tech software to look at your roof’s orientation (north, south, east, or west), the pitch of the tiles, and any potential "sun-blockers" like nearby oak trees or your neighbour’s chimney stack. 🏡☀️ Seeing your property allows us to spot any technical hurdles—like the location of your consumer unit (fuse board) or where the mains electricity enters the building—long before we arrive with our ladders.

For our local customers in Derby and across the East Midlands (we cover a 40-mile radius!), providing this info upfront means we can give you a lightning-fast, accurate quote without you having to wait for a physical visit. Plus, because we offer a 10-year workmanship guarantee on all solar installations, we want to make sure the design is 100% "spot on" from day one. It’s all about making your transition to renewables as smooth and "shock-free" as possible!

Question 3

How long will my scaffold stay up for?

Accepted Answer

We completely understand that having scaffolding hugging your house isn't exactly the most aesthetic look! 🏡👷‍♂️ One of the most common questions we get from our domestic customers across Derby and the wider East Midlands (we cover a 40-mile radius!) is how long their property will look like a temporary building site.

Think of the scaffolding as the warm-up act before the main event. We want to keep the disruption to your daily life to an absolute minimum, so we keep the timeline tight and efficient:

Going Up: We aim to have our trusted scaffolding partners erect the structure the working day before your installation is scheduled to start.

Coming Down: Once the final solar panel is securely in place and our team has packed up, the scaffolders will be back to safely dismantle and remove it the working day after your installation ends.

It really is as simple as that! We don't want you feeling like you're living in a metal jungle any longer than absolutely necessary. Plus, once that scaffolding is whisked away, you’ll be left with a brilliant, clean-energy-generating roof that is fully backed by our rock-solid 10-year workmanship guarantee on all solar installations. ☀️⚡

Question 4

Do I get instructions for how my new solar system works?

Accepted Answer

Getting a brand new solar system is incredibly exciting, but looking at all those new cables, inverters, and consumer unit connections can feel a bit like sitting in the cockpit of an aeroplane! ✈️ Don’t panic—we absolutely will not just pack up our tools, wave goodbye, and leave you scratching your head.

At Power & Control, we pride ourselves on delivering a five-star handover for all our domestic customers across Derby and the East Midlands (covering our full 40-mile radius). Here is exactly how we get you up to speed:

The Grand Tour: Before our friendly engineers leave, they will give you a full, jargon-free run-through of your brand new setup. We’ll show you where everything is, how it safely connects to your mains electricity, and what to look out for.

App Setup & Sync: Because we install all the top-tier, high-quality brands (whether that's a Tesla Powerwall, a Sigenergy inverter, or anything in between), we are experts in their software. We will help you download the relevant app to your phone or tablet, get it connected to your Wi-Fi, and show you exactly how to manage and monitor your system.

Energy at your Fingertips: We'll teach you how to track exactly how much free sunshine you are pulling in ☀️, monitor your battery storage levels 🔋, and see your home's energy consumption—all from the comfort of your sofa with a cuppa! ☕

We want you to feel completely confident and in control of your new green energy setup. And remember, long after we've shown you the ropes, you are fully backed by our cast-iron 10-year workmanship guarantee on all solar installations. 🏡⚡

Question 5

Will the Sigenergy battery keep my house or business running during a power cut?

Accepted Answer

There is nothing more frustrating than a sudden grid blackout, especially when you have a roof full of solar panels and a battery full of energy! With many standard grid-tied solar systems, a power cut means your system safely shuts down, leaving you in the dark. However, the Sigenergy system is designed to keep you up and running when the grid fails.

By including the optional Sigenergy Gateway unit in your installation, your SigenStor system transforms into a fully automated, whole-property backup solution. The moment the Gateway detects a power outage from the national grid, it physically safely disconnects your property and switches to your stored battery power. The most impressive part? It does this in exactly 0 milliseconds. The switchover is so instantaneous that your lights won't even flicker, your computers won't reboot, and your Wi-Fi won't drop out. You might not even realize there’s a blackout happening outside!

This feature is incredibly reassuring for our domestic customers across Derby and the Midlands who want to keep the lights on and the fridge cold. It is equally critical for our commercial clients nationwide who simply cannot afford business downtime or lost data due to power failures. As an independent installer of all premium brands, we love recommending Sigenergy for its robust off-grid capabilities. Plus, because we stand by the quality of our work, the entire solar and battery installation comes with our comprehensive 10-year workmanship guarantee.

Question 6

Is the Sigenergy battery safe to have in my home or business?

Accepted Answer

Safety is usually the number one question we get asked when it comes to battery storage, and rightly so! It is incredibly important to us that you feel completely secure with the technology powering your property. We are thrilled to reassure you that the Sigenergy SigenStor is arguably one of the safest energy storage systems on the global market today. 🛡️🏡

Sigenergy doesn't take any chances. The system is engineered with industry-leading chemistry and multiple layers of physical protection working 24/7:

Highly Stable Chemistry: It uses Lithium Iron Phosphate (LiFePO4 or LFP) battery chemistry. Unlike the older lithium-ion batteries found in smartphones, LFP is remarkably stable, environmentally friendlier, and highly resistant to overheating.

Advanced Smart Sensors: Highly sensitive temperature sensors and built-in smoke detectors constantly monitor the system's internal health. 🚨

Physical Protections: The modules feature decompression pressure relief valves and heat-insulating aerogel pads to manage internal temperatures perfectly.

Internal Fire Suppression: Most impressively, every individual battery module contains its own dedicated fire suppression module. If an issue ever arises, it automatically triggers to instantly extinguish the problem locally before it can spread.

As an independent installer of all the major premium brands, we take safety incredibly seriously. Whether we are installing a single tower for a family home in Derby and the East Midlands, or commissioning a massive multi-stack energy array for a large commercial facility anywhere in the UK, we want you to sleep soundly. To back up our absolute confidence in the products we install and the quality of our engineering, your solar and battery installation is comprehensively covered by our 10-year workmanship guarantee, while any general electrical work carries our 2-year workmanship guarantee. 🔋✅
