Solar panels work by allowing particles of light, or photons, to knock electrons free from atoms, which generates a flow of electricity. This is based on the photovoltaic effect. Here are the key steps in the process:

1. Absorption of Sunlight: Each solar panel is made up of many smaller units called photovoltaic cells, usually made of silicon. When sunlight hits these cells, it’s absorbed by the silicon.
   
   

2. Generation of Electron Flow: The absorbed light energy knocks electrons loose in the silicon. The structure of the silicon and the use of additional elements in the cell create an electric field that pushes these loose electrons in a directional current.
   
   

3. Capture of Electricity: Metal conductive plates on the sides of the cells collect the electrons and transfer them to wires.

4. Conversion to Usable Power: The resulting electricity is in the form of direct current (DC), which needs to be converted to alternating current (AC) for most home uses. This is accomplished using an inverter.
   
   

The result is usable electricity that can power your home. And the great part is that as long as sunlight is hitting the solar panels, this process keeps happening, providing a renewable source of energy.

Solar panels require sunlight to generate electricity, so they do not produce power in the absence of light, such as during the night. However, on cloudy or overcast days, solar panels can still produce electricity, albeit at a reduced rate compared to clear, sunny conditions.

Furthermore, many solar power systems are connected to the grid, and excess power produced during sunny periods is fed back into the grid. This can offset electricity consumed at night or during less sunny periods, effectively allowing solar power users to draw on the power they’ve generated even when their panels aren’t actively producing electricity.

Alternatively, some solar systems are equipped with battery storage, which stores excess power generated during the day for use during the night or on cloudy days. This can provide a source of power when the panels themselves are not generating electricity, making solar energy more consistent and reliable.

In summary, while solar panels themselves do not work without sunlight, systems can be designed to provide power even during these times using either grid connection or battery storage.

While solar panels can be installed on most homes, there are several factors that can influence their effectiveness:

1. Sunlight Exposure: Solar panels are most effective in areas that receive a lot of sunlight throughout the year. If a property is in a location that frequently has overcast or rainy conditions, the effectiveness of solar panels may be reduced.
   
   

2. Roof Orientation and Angle: The orientation and angle of a home’s roof can greatly affect the performance of solar panels. In the northern hemisphere, a south-facing roof is typically best. The optimal angle for the panels depends on the latitude, but is often around 30-40 degrees.
   
   

3. Roof Condition and Size: The roof needs to be in good condition and large enough to install the number of panels required to generate the desired amount of electricity. Older roofs might need to be repaired or replaced before installing solar panels to avoid having to remove and reinstall the panels to carry out roof work later.
   
   

4. Shading: Large trees, tall buildings, or other structures that cast shade on the roof can significantly reduce the efficiency of solar panels.
   
   

5. Local Regulations: Some areas may have regulations or homeowner association rules that restrict the installation of solar panels. It’s important to check local regulations before installing solar panels.
   
   

6. Cost and Payback Period: The initial cost of installing solar panels can be quite high, although many jurisdictions offer incentives that can help offset this cost. The savings on electricity bills over time will eventually cover the initial investment, but it’s important to calculate the payback period to ensure it makes financial sense.
   
   

Therefore, while solar panels can technically be installed on any home, they are not necessarily suitable for every home. A site assessment by a professional can help determine if solar panels would be a good fit for a specific property.

Solar panels are a highly eco-friendly option for power generation. They tap into the sun’s energy, an abundant and renewable resource, to produce electricity without releasing harmful greenhouse gases. Once installed, they operate quietly with minimal impact on the surrounding environment, contributing to energy independence, particularly beneficial for remote areas. While there are environmental costs associated with the manufacturing, installation, and disposal of solar panels, these are often outweighed by their long-term benefits. Modern solar panels typically recoup the energy used in their production within 1-4 years, and despite a gradual decrease in efficiency, they can effectively serve for 25-30 years or more. Additionally, advancements are continuously being made in the sector, further improving the production, efficiency, and recyclability of solar panels, making them an increasingly sustainable choice for power generation.

In the UK, you usually don’t need planning permission to install solar panels on your home if the installation adheres to specific conditions. The solar installation is typically considered “permitted development” which doesn’t require planning permission.

However, it’s always a good idea to check with your local council before installing solar panels, as some areas might have different requirements, especially if you live in a listed building or a conservation area. Always ensure you adhere to the local rules and regulations to avoid any issues in the future.

The time it takes to install a typical residential solar PV system can vary greatly depending on a number of factors, including the size and complexity of the system, the condition of your roof, weather conditions, and the experience of the installation company.

However, as a general guideline, the physical installation of the solar panel system at Affinity Solar Solutions – which involves mounting the panels on the roof and connecting them to your home’s electrical system – usually takes 1 to 3 days for a typical home.

Please note that the total time from decision, to having a working solar system can be much longer. This includes time for site assessment, system design, obtaining any necessary permits or approvals, and scheduling the installation. This process can take several weeks to a few months.

After installation, the system may need to be inspected and connected to the grid, which can add additional time before it is operational. Depending on local regulations and the utility company, this can add days, weeks, or even a few months to the total timeline. Therefore, it’s always best to start the process well in advance of when you hope to have the system running.
