They were so accommodating and worked around the clock to make things work out for us. They were able to ship our car along side our trailer and get the all clear to drive off in such amazing time. I would highly recommend their company to do the job.

Designed to make a real difference.

Energy Independence

Solar panels designed for Surrey weather. Our next gen panels increase energy generation from both sides of the panel. So you get more consistent power output even in low light Surrey weather conditions.

Avoid the most common issue in a solar system - inverter failure in the first 10 years. Our electrical engineers hand-select, long lasting Tier 1 inverters that work hard all day long. And you’ll get the peace of mind of a 12 year inverter warranty.

Keep your power on 24/7. We use energy-dense cell chemistry batteries that will power even the highest-demand household, without compromising on safety. With no messy wires, hot parts and clutter, your battery will be touch-safe for the whole family.

Environmental Impact

Your personal climate solution. Long lasting solar system with advanced battery storage to save excess energy means zero-emissions power generation without reliance on dirty grids.

High-efficiency photovoltaic panels maximise sunlight conversion into electricity, reducing your household emissions from the moment they're installed. High tech, low emissions.

Cut carbon without changing your lifestyle. You keep using energy as usual, while your advanced solar system quietly reduces your carbon footprint in the background.

Stress-free Solar Savings. Total Energy Transformation.

The Big Blue Sky Energy Teeam

A message from our team

When it comes to solar and battery storage, you don’t want smooth talkers or shortcuts—you want real experts who know what they’re doing.

We don’t do one-size-fits-all. Every home, roofline, and family energy need is different. That’s why we take the time to ask the right questions up front and design a system that truly fits your home and your budget. It means you end up with a solar setup that performs for decades, not just a quick fix.

This isn’t about “window shopping.” Solar is one of the most important investments you’ll make for your home. We know it’s both a technical and a financial decision—and it deserves careful planning, not pushy sales tactics.

Most of all, we believe in keeping it human. When you reach out, you won’t get bounced around a call centre or left talking to a chatbot. You’ll deal directly with our small, Surrey-based team who will guide you from first conversation to installation and beyond.

We’re a team of certified electrical engineers and qualified roofers. And we wanted to give Surrey homeowners a trustworthy, local team that puts quality first.

If you’re serious about taking control of your energy future, we’re here to make it happen—with honesty, expertise, and work we’d be proud to put on our own homes.

The Team at Big Blue Sky Energy

I have questions about your process.

General Questions

How does solar PV work?

Solar PV (photovoltaic) panels convert sunlight into electricity using semiconductor materials. This electricity can be used in your home, stored in a battery, or exported back to the grid.

Will solar panels work in the UK?

Yes. Solar panels don’t need direct sunlight to work; they generate electricity even on cloudy days. While output is higher in summer, solar is effective year‑round.

Do I need planning permission to install solar panels?

In most cases, no. Solar PV systems are considered “permitted development.” Exceptions may apply if you live in a listed building, conservation area, or have specific local restrictions.

How long do solar panels last?

Most panels come with a 25‑year performance warranty. They can continue generating electricity well beyond that, typically 30+ years.

What maintenance is required?

Solar PV systems require very little maintenance. An occasional clean (especially if you live in a dusty or coastal area) and periodic professional checks are recommended.

Cost & Savings

How much does a solar PV system cost?

The cost depends on system size, battery options, and roof type. A typical residential system ranges between £5,000–£12,000, while larger systems cost more.

How much will I save on my electricity bills?

Savings depend on your energy use, roof orientation, and whether you add a battery. Many households save 50–80% on electricity bills.

Can I sell excess energy back to the grid?

Yes. Through the Smart Export Guarantee (SEG) in the UK, you are paid for exporting unused electricity to the grid. Rates vary by supplier.

How long does it take to pay back the investment and what is your Payback Guarantee?

The typical payback period is 6–10 years, depending on your energy usage, local export tariffs, and whether a battery system is included. Every system we install comes with a custom payback period guarantee. Based on your tailored quote, we’ll stipulate how many years it will take for your solar savings to cover your investment—and we stand by that timeline. If your solar system hasn’t reached its guaranteed payback period, we’ll credit you the difference in savings based on your quote’s projections—so you never lose out on the return you were promised.

Solar Batteries

Do I need a battery with my solar panels?

A battery isn’t essential, but it increases self‑consumption by storing excess daytime electricity for evening use. It maximises savings and provides backup power (with the right setup).

How long do solar batteries last?

Modern lithium batteries typically last 10–15 years, with warranties ranging from 5–12 years depending on manufacturer.

Can I add a battery later?

Yes. Most solar PV systems can be retrofitted with a battery at a later stage.

Can batteries provide power during a power cut?

Yes—if installed with a backup or gateway unit. Standard systems without this feature will shut down during an outage for safety reasons.

How much battery storage do I need?

It depends on your energy usage. A typical home uses 6–12 kWh per day, so a 5–10 kWh battery is common. We’ll size the system to suit your needs.

Installation

How long does installation take?

Most residential solar PV systems take 1–3 days to install. Adding a battery may add another day.

What happens during installation?

Our team will fit the panels, connect the inverter and battery (if applicable), and set up monitoring. We’ll also handle any scaffolding and paperwork.

Will the installation damage my roof?

No. Panels are mounted on roof rails designed to protect your roof. Installations are carried out to MCS and building regulation standards.

Can solar panels be installed on flat roofs?

Yes. Special mounting systems allow panels to be installed at the optimal angle.

Technical

How much space do I need for solar panels?

A typical 4 kW system requires around 20 m² of roof space. Larger systems need more space.

Do panels work in the shade?

Shading reduces performance. However, optimisers and micro‑inverters can minimise shading impact.

What’s the difference between an inverter and a battery inverter?

A standard inverter converts DC from panels into AC for your home. A hybrid inverter also manages charging/discharging of a battery.

Will solar panels increase my home’s value?

Yes. Homes with solar panels are often more attractive to buyers due to lower energy costs and sustainability benefits.

Environmental Impact

Are solar panels recyclable?

Yes. Around 95 % of a panel’s materials can be recycled, including glass, aluminium, and silicon.

How much CO₂ will I save with solar?

A typical residential system can reduce carbon emissions by 1–2 tonnes per year.

Warranties & Support

What warranties come with solar panels and batteries?

We only install panels that have a 25‑year performance warranty and a 25‑year product warranty. We install Givenergy batteries and inverters because they are high quality and come with a 12‑year warranty.

Do you offer ongoing support?

Yes. We provide system monitoring, maintenance options, and after‑care support to ensure your system performs at its best.
