A new build or extension is an expensive undertaking, and although some homeowners will look to keep all their costs to a minimum, others will see it as a smart investment opportunity that they can really take advantage of...

It's no secret that solar panels are the best way to turn your home into a more self-sufficient, economical and sustainable place to live - cutting down on electricity running costs, turning towards clean, renewable energy and a cleaner way of living.

Whether you're creating room for a growing family, a home office or even something entirely more ambitious such as a holiday annex for paying guests or rentals, the possibilities are great for solar energy.

To help you out, we've put together our top 4 reasons why you need to consider installing Plug-In Solar Panels, including useful information and cost-cutting data on exactly what you could save year-on-your and all the appliances you'll be able to use as well...

Save Money On Your Electricity Bills

By investing in solar, you could potentially generate enough energy to supply the entire building.

A 4kW Plug-In Solar Kit for a large home could save more than £31,000.00 on energy bills over 20 years, with a return of investment period of around 5 and a half years.

Simply install Plug-In Solar Panels and start your journey to energy self-sufficiency...

How Much Energy Can I Use And Save With Plug-In Solar?

The size of the Plug-In Solar kit you choose to buy will determine the energy savings you will make.

For example, a 4kW Plug-In Solar Kit (the size suitable for a family of 4) is estimated to generate around 3,945kWh of electricity per year. This is enough to cover ALL the following household appliances:

  • Dishwasher (3 times per day)
  • An Electric Oven (18 times per week)
  • An LCD TV (12 hours per day)
  • A Washing Machine (15 times a week)

A smaller, 2.5kW Plug-In Solar kit, is estimated to generate around 2,466kWh of electricity per year. That’s enough energy to power ALL the following:

  • Dishwasher (10 times per week)
  • Electric Oven (14 times per week)
  • LCD TV (10 hours per day)
  • Washing Machine (8 times per week)

Installation Couldn't Be Easier

The installation and use of solar panels is often seen as a specialist job, but this is not the case...

"Plug and Play technology"

Plug-In Solar uses Plug and Play technology, and for new builds and extensions, the installation can simply be signed off by the on-site electrician.

We offer a whole variety of Plug-In Solar kits to suit your needs, just ask us for advice on which is the best solar kit for you.

Which Roofs Are Suitable For Plug-In Solar?

Plug-In Solar Kits can be installed on Tile/Slate Roofs, Metal/Wooden Roofs, Flat Roofs, or on the Ground. The Solar Panels can also be integrated into the roof using one of our In-Roof (BIPV) Solar Kits. These allow the panels to sit flush with the tiles/slates and can reduce the spend on tile/slate equipment. We supply all the equipment necessary to complete your installation whichever kit you choose.

The beauty of Plug In Solar is that there’s no need for an MCS Certification to be able to fit the panel/s. Each Plug-In Solar kit comes with a detailed installation guide with extensive information about health and safety. This covers wiring your kit into the mains electricity and the paperwork you must complete to commission your panels with the local Distribution Network Operator (DNO).


Plug-In Solar is flexible and modular. If you want to extend your solar kit at any point in the future, you can simply plug in another panel to increase the wattage. We also offer a large array of energy storage options, and energy-saving devices, such as Immersion Diverters, so please ask us for advice and information on these products. For more information or to purchase a Plug-In Solar Kit, please visit the Plug-In Solar section of our website or contact us by email: sales@roofgiant.com, or on our telephone helpline: 01858 455055.

*Disclaimer: The performance of solar PV systems is impossible to predict with certainty due to the variability in the amount of solar radiation (sunlight) from location to location & from year to year. This estimate is based upon the Government’s standard assessment procedure for energy rating of buildings (SAP) and is given as guidance only. Illustrative solar PV performance figures only. Figures are given in good faith but do not constitute "Financial Advice". Yearly PV output uses a factored degradation over time based on industry estimates. Photovoltaic Panels will not be shaded (e.g. by Trees or Buildings) as shading affects PV output. Specific appliance ratings and equipment age will affect energy consumption and these examples are guidelines only. Appliance consumption information from Center for Sustainable Energy (www.cse.org.uk). Based on A-Rated (or higher) appliances. These figures assume that you have south facing 250W polycrystalline solar panels, tilted at an angle of 35°, you pay 14.37p per unit of electricity (Standard rate as of May 2017 source: Energy Saving Trust) and 100% of the solar electricity that you generate will be used in your home. Calculations assume an annual energy price inflation of 10% & include solar radiation & system losses, in a western UK location, due to Temperature 6.8% and Angular Reflectance 2.9%, as well as other losses (e.g. Cables, Inverter) of 12%.
