What exactly do solar panels do?

Solar panels take sunlight and turn it into electricity for your home. They use solar cells to create direct current (DC), which an inverter then changes to usable electricity (AC) for your lights, appliances, and more.

Why should I get solar panels for my home?

Installing solar panels can cut your energy bills, increase your property’s value, and reduce your carbon footprint. You also become less reliant on the energy grid.

How long will my solar panels last?

Most solar panels last around 25 to 30 years. After that, they still work but at reduced efficiency. Inverters and batteries might need replacing sooner, usually within 10 to 15 years.

Will solar panels still work if it’s cloudy or raining?

Yes, they still work in bad weather. Solar panels generate some energy from daylight, even when it’s cloudy or rainy—just at a lower rate.

How do I know what size solar system I need?

It depends on your electricity usage, your roof size, and how much sun your home gets. We’ll assess your needs and recommend the right system size for you.

How much can I save each month with solar panels?

Most customers save between 50% and 100% on their electricity bills. The amount depends on your system size and how much energy you use.

Do solar panels need regular maintenance?

Not much! Solar panels are low-maintenance. Just keep them clean and check your system now and then. We recommend a professional check-up once a year.

Can you install solar panels on any roof?

Yes, in most cases. We install systems on tiled, metal, and flat roofs using the correct fixings. If your roof isn’t suitable, we can discuss ground-mounted options.

How long does it take to install solar panels?

The actual install usually takes 1 to 2 days. From start to finish—including design, approval, and grid connection—it can take a few weeks.

Will having solar panels make my home more valuable?

Yes, solar panels can boost your home’s value. They make your property more energy-efficient and attractive to eco-conscious buyers.

Can I power my entire home with solar energy?

Yes, depending on your system size and whether you have battery storage. A well-designed system can meet all your home’s energy needs, especially with storage.

What warranties come with solar panels and parts?

Panels typically come with a 20–25 year warranty. Inverters often have 5–12 year cover. We’ll explain all warranties before installation.

What is battery storage and how does it help?

Battery storage lets you store extra solar energy to use at night or during power cuts. It makes your home more energy independent and helps you save even more.

Can you install an EV charger at my home?

Absolutely. We offer smart EV chargers that work alongside your solar panels, so you can charge your car using free solar energy.

Do I need planning permission for solar panels?

Most homes don’t need planning permission for solar panels. There are a few exceptions, like listed buildings or conservation areas, but we’ll check that for you.

Off-Grid Solar and Battery System in Copthorne

How can we help?

We installed this off-grid solar PV system for a customer in Copthorne, and they now enjoy complete energy independence.

LocationCopthorne

Solar20 x Aiko 450W, 9 kWp

Battery4 x Pylontech

InvertersVictron 11.5kW and 10kW

The goal

The aim was a system that runs independently of the grid, with enough generation and storage to supply the property on its own.

What we installed

20 x Aiko 450W solar panels (9 kWp)
4 x Pylontech battery storage units
1 x Victron Energy 11.5kW inverter, isolated
1 x Victron Energy 10kW inverter

Why we designed it this way

Off-grid systems have no grid to fall back on, so the battery bank and inverters have to be sized for the property’s peak demand as well as its daily use. Victron inverters are widely used in off-grid systems for their reliability and control, and Pylontech batteries stack to build a larger bank.

Running two inverters gives the capacity to cover larger loads and keeps the system flexible.

How it works day to day

The panels charge the battery bank during the day and the inverters supply the property from the batteries. With no grid connection, the system is designed so the stored energy carries the property through the evening and overnight.

Questions homeowners ask about a system like this

Is off-grid right for most homes?

Usually not. For most homes, a grid-tied system with a battery and backup gives the same security with far less outlay. Off-grid suits properties where a grid connection is impractical or unwanted.

What happens in a long run of dull weather?

Off-grid systems are designed with this in mind, and some sites add a backup generator for extended dull spells.
