How do I know if my house is suitable for solar panels installation?

Determining if your house is suitable for solar panel installation involves several factors:

Roof Orientation and Angle
Ideally, your roof should face south, southeast, or southwest to receive the most sunlight throughout the day. The angle of the roof should also be suitable for efficient solar panel placement.
Minimal shading from trees, buildings, or other obstructions is optimal for solar panels to receive maximum sunlight exposure.
Roof Condition
Your roof should be structurally sound and in good condition to support the weight of solar panels. If your roof requires repairs or replacement soon, it's advisable to address these issues before installing solar panels.
Energy Usage
Assess your household's energy consumption to determine if solar panels can adequately meet your needs. This evaluation helps determine the appropriate size and number of solar panels required.
Local Regulations
Check local regulations and building codes to ensure compliance with any requirements or restrictions related to solar panel installation in your area.
Consultation with Solar Expert
Consider consulting with our solar installation experts who can assess your property's suitability for solar panels and provide personalised recommendations.

How much can I expect to save on energy bills after installing solar panels?

The amount of money use can save on your energy bills after installing solar panels will depend on the following factors:

Type of Solar Panels

Type of Solar Panels

Different types of solar panels, such as monocrystalline, polycrystalline, and thin film, have varying efficiencies and performance characteristics that can affect energy production and savings.

Home's Electricity Consumption

Home's Electricity Consumption

The amount of electricity your household consumes directly impacts the potential savings from solar panels. Higher electricity consumption may result in greater savings.

Size of Solar Panel System

Size of Solar Panel System

The size of your solar panel system, measured in kilowatts (kW), determines its capacity to generate electricity. Larger systems can produce more energy and potentially yield higher savings.

Roof Orientation and Angle

Roof Orientation and Angle

The orientation and angle of your roof relative to the sun affect the efficiency of solar panel performance. Roofs facing south typically receive the most sunlight, optimising energy production.

Payments through SEG Schemes

How do solar panels work?

Solar panels work by harnessing the energy from sunlight and converting it into electricity through a process called the photovoltaic effect.

When sunlight strikes the surface of the solar panels, the PV cells absorb photons (particles of light). This energy absorption excites electrons within the semiconductor material, causing them to break free from their atoms.

The flow of electrons creates an electric current within the PV cell. This current is direct current (DC) electricity, which is the type of electricity produced by solar panels.

Since most household appliances and the electrical grid use alternating current (AC) electricity, the DC electricity generated by the solar panels needs to be converted into AC electricity. This is done by an inverter, a device that converts DC electricity into AC electricity.

The AC electricity produced by the inverter can then be used to power household appliances, lights, and other electrical devices in your home.

If your solar panel system generates more electricity than your home consumes, the excess electricity can be fed back into the grid for credit or compensation through net metering or other incentive programs.

Overall, solar panels work by converting sunlight into usable electricity through the photovoltaic effect, providing a renewable and environmentally friendly source of power.

Solar Panel Installation Grants FAQs

Listed below are some of the common questions and answers for the UK Government ECO4 solar panel grants. If you cannot find the answer to your question, then simply contact us for a free consultation.

Yes, solar panels can still generate electricity on cloudy days, although their efficiency may be reduced compared to sunny days. Cloud cover reduces the amount of sunlight reaching the solar panels, which in turn decreases their power output. However, modern solar panel technology is designed to be efficient even in diffuse or indirect sunlight. While solar panels may produce less electricity on cloudy days, they can still contribute to powering homes and reduce reliance on grid electricity.

The number of solar panels you need depends on several factors:

Energy Consumption: Calculate your average monthly or yearly electricity consumption to determine how much energy your solar panel system needs to produce. This information helps estimate the size of the solar panel array required to meet your energy needs.

Sunlight Availability: Assess the amount of sunlight your location receives throughout the year. Areas with more sunlight require fewer solar panels to generate the same amount of energy compared to regions with less sunlight.

Panel Efficiency: Consider the efficiency of the solar panels you plan to install. Higher efficiency panels can generate more electricity in limited space, potentially reducing the number of panels needed.

Roof Space: Evaluate the available roof space for solar panel installation. The size and orientation of your roof will determine the maximum number of panels that can be installed.

Regulatory Restrictions: Check local regulations and building codes that may impose restrictions on the size or placement of solar panel systems.

Fitting solar panels typically doesn’t require planning permission unless your home is situated in a conservation area or is listed as a historic building. In such cases, it’s advisable to contact your local council to ascertain the appropriate steps to take.
Grants for solar panel installation are accessible to property owners and individuals renting from private landlords.
The Energy Company Obligation (ECO) is a government initiative that mandates larger energy providers to participate. Geared towards enhancing energy efficiency in homes, particularly for those struggling with fuel poverty, it gives priority to households where energy bills comprise 10% or more of their income, including recipients of benefits and families residing in social housing.

You could be eligible for an ECO grant if you receive at least one of the following benefits:

  • Income Support
  • Child Benefit
  • Universal Credit
  • Housing Benefit
  • Income-related Employment and Support Allowance (ESA)
  • Income-based Jobseeker’s Allowance (JSA)
  • Tax Credits (Child Tax Credits and Working Tax Credits)
  • Pension Guarantee Credit
  • Pension Savings Credit
  • Warm Home Discount Scheme
  • Live in a property with an Energy Performance Certificate (EPC) of D or lower
The duration for installing solar panels can vary based on several factors, including the size of the system, the complexity of the installation, the number of panels, and the availability of materials and labour. On average, a residential solar panel installation typically takes anywhere from one to three days to complete. However, larger installations or projects with specific requirements may take longer.
Each property varies, and every household requires unique energy needs. Nonetheless, it’s approximated that the average household could save £900 – £1,200 annually on their energy expenses by generating their own electricity via solar panels. These savings include direct reductions from not relying on power from the National Grid and earnings from selling surplus energy back to the grid through the Smart Export Guarantee (SEG).
