Why Solar in West Sussex Works

West Sussex is one of the sunniest counties in the UK — with up to 1,919 hours of sunshine a year. That makes it perfect for solar. From Worthing to Crawley, homes here can dramatically cut energy bills and carbon emissions with solar PV and battery systems.

  • The West Sussex County Council is investing in solar across public buildings and supports residents in lowering their carbon footprint.
  • Group-buying schemes like Solar Together West Sussex have helped thousands access affordable solar.
  • With mild weather and strong solar output, local homes benefit from long-lasting systems that work well even on cloudy days.

“We’ve installed dozens of systems across Chichester, Worthing and Mid Sussex,” says David, Senior Installer at TLGEC. “Homeowners here are really seeing the savings.”

Benefits of Installing Solar Panels

Every year the sun produces 8,000 times more energy than we consume globally, ready to use whenever we need it, so why not make the most of this free supply?

As the UK makes permanent moves away from fossil fuels, power outages are likely to become more frequent as our grid struggles under the pressure. If you have solar panels, you are far less likely to be affected, and those with solar and Tesla Powerwall will enjoy seamless backup during outages. Beyond creating a future-proof sustainable energy source, rooftop solar panels have some impressive benefits that should be taken into consideration.

We have installed many solar panel systems in West Sussex. Here are some of benefits are customers are enjoying.

  • You can reduce your carbon footprint and impact on the environment.

    In a world where reducing our personal carbon footprints is becoming a necessity, solar panels are the answer. As solar panels generate green, renewable energy, there are no harmful pollutants released into the earth’s atmosphere. You will play a direct part in protecting the future of our planet. This is the most rewarding benefit echoed by almost all our customers.

  • You can make money from your solar power and sell the surplus electricity.

    Any electricity you don’t use will be sold back to the grid to be used by an energy supplier. Therefore, there is no wastage, and you can earn money from the unused electricity you produce, making the overall system more efficient.

  • You can cut your electricity bills.

    Sunlight is free. After paying for the initial installation, your roof-mounted solar panels will generate all the electricity you need, and more. Your electricity costs will be significantly reduced.

  • You can protect yourself from rising energy bills.

    By going solar, you are saving money on rising electricity bills from day one.

  • You can future-proof your home now before prices rise

    With the UK moving away from fossil fuels, you’re going to be happy to have swapped over to solar energy sooner, rather than later.

  • You can increase the value of your property.

    Solar panels actually increase the value of your home and may make the home more attractive to potential buyers. Green energy solutions are now seen as very desirable as home buyers become more eco-conscious.

Choosing Solar Make's Sense

Converting to solar energy is not only good for you and your wallet in the long term, but you are actively helping fight climate change and are protecting the environment. While installing solar panels on your roof may seem like the more expensive option upfront, the costs are quickly mitigated by the savings and money made from your solar panels.

Solar Panel (PV) FAQs

To ensure you have all the information you require at your fingertips, we have compiled a list of frequently asked questions. If you still have a question then feel free to reach out and get in touch. Our team is extremely knowledgeable and here to help.

Do solar panels work in West Sussex?

Yes — West Sussex gets up to 1,919 hours of sunshine a year, making it ideal for solar panels. Even on cloudy days, panels can still generate electricity efficiently.

Do solar panels work in winter?

A common myth is that solar panels do not work during winter, but on the contrary, the cold temperature in West Sussex in the winter will typically improve solar panel output. The white snow can also reflect light and help improve PV performance. Winter will only hurt solar production if the panels are covered with snow.

How many solar panels are needed to power a typical house?

It’s estimated that the average one-bedroom house needs six solar panels, while a three-bedroom house needs ten. The number of solar panels you will need to power your home depends on the size of your property. Many customers in Crawley and Worthing now power their homes almost entirely on solar.

Do solar panels work in the rain?

Solar panels will still work even when light is reflected or blocked by clouds. Rain actually helps keep your panels operational by washing away any dust or dirt that may obstruct the PV cells.

Can you run a house on solar power alone in West Sussex?

Yes, you can power your entire home using solar energy, even in the winter.

How long do solar panels last?

The industry lifespan of a typical solar panel is 25 years.  However, we use the SunPower panels which have a 40-year warranty, giving you that extra peace of mind.

Do I need planning permission to install solar panels?

Very few of our customers who have chosen solar panel installation in East Grinstead, Crawley, Worthing and the surrounding areas have required planning permission. You need to apply for planning permission only if your solar panels will protrude more than 20cm from the external surface of the wall or roof slope.

How much do solar panels cost?

The price of your solar panels will depend on multiple factors such as the size of your home, how much you want to rely on solar energy, and what you are using the solar panels for. For a more detailed price breakdown, do not hesitate to get in touch with us.

How long does solar panel installation take?

Solar panel installation can take up to two days. A considerable amount of time is spent on constructing scaffolding for the panels, so if you do not require scaffolding, the installation will take less time.

How can I make the solar PV system less visible?

Manufacturers have started offering panels with black frames to make the solar panels less conspicuous and obvious when on your roof. TLGEC have fitted many of these in West Sussex

If I get an electric car, can I charge it from my solar panels?

Yes, you can charge your electric car using your solar panels. As official partners of Tesla, we offer Tesla Powerwall that works in conjunction with your solar panels. This means that your solar panels will charge the Powerwall, which will hold energy that you can use to directly charge your car.
