This would alleviate strain on the national grid during peak periods and enhance overall grid stability.
Example: Imagine a scenario where every house in the UK has solar panels. On a sunny day, when electricity demand is high, each house would be generating its own electricity and exporting excess energy back to the grid. This would not only meet the demand but also contribute to the national grid, reducing the need for traditional power plants. As a result, the reliance on fossil fuels would decrease, and the UK’s energy mix would become more sustainable and environmentally friendly.
In conclusion, if every house in the UK were fitted with solar panels, it would bring about many benefits, including increased renewable energy generation, reduced energy costs, job creation, and improved environmental sustainability.
A 400W solar panel typically has a physical size of around 1.69m by 1m, which is equivalent to approximately 5.4 feet by 3.25 feet. This size is known as the standard 60-cell solar panel dimensions. However, it is essential to note that the exact size may vary slightly depending on the manufacturer and specific model.
To illustrate, let’s consider an example of a popular 400W solar panel model. The XYZ Solar Panel 400W has a dimension of 165cm by 100cm. This panel comprises 60 solar cells, each producing approximately 6.67W of power. By connecting these cells in series, the total power output of the panel is 400W.
When installing a 400W solar panel, it is crucial to consider the available space and mounting requirements. The panel will require a certain amount of area, typically around 1.65 meters squared, to be installed efficiently. It is also important to consider factors such as roof strength, shading, and optimal positioning for maximum sunlight exposure. 
Let’s now assume you want to install a 4kW array. You would need to install ten 400W panels. This means you’ll need a minimum area of 16.5 meters squared available – panels can be arranged in both landscape and portrait orientation with a varying number of rows and columns to suit the space available.
Suppose you are unsure about the specific dimensions of a 400W solar panel. In that case, it is recommended to consult the manufacturer’s specifications or reach out to us at Glo Renewables, who can provide accurate measurements based on the particular panel you are interested in.
The answer to whether it is better to have more solar panels or more batteries ultimately depends on your specific needs and goals. Both solar panels and batteries play crucial roles in a solar power system, but they serve different purposes.
Solar panels convert sunlight into electricity. They harness the sun’s energy and generate DC (direct current) electricity. The amount of electricity generated depends on various factors, such as the size of the panels, their efficiency, and the amount of sunlight they receive. In general, having more solar panels means you can generate more electricity, which is beneficial if you are aiming to maximise your energy production.
On the other hand, batteries are used to store excess electricity generated by solar panels. This stored energy can be used when the sun is not shining, such as during night time or cloudy days. Batteries allow you to have a continuous power supply, reducing the reliance on the grid and maximising the use of solar energy. Having more batteries means you can store more electricity, which is advantageous if you want to have backup power during extended periods of low sunlight or if you experience frequent power outages.
To determine whether you should prioritise more solar panels or more batteries, consider the following factors:
1. Energy Needs: Assess your energy consumption and determine how much electricity you need to generate and store. If you have high energy demands, it might be beneficial to invest in more solar panels to ensure you generate enough electricity.
2. Grid Dependency: Evaluate your reliance on the grid. If you want to reduce your dependence on the grid and have a self-sustaining solar power system, investing in more batteries might be a better option.
3. Budget: Consider your budget constraints. Solar panels and batteries can be expensive investments. Determine how much you are willing to spend and allocate your resources accordingly.
4. Location: Take into account your geographical location and the amount of sunlight you receive. If you live in an area with ample sunlight, more solar panels might be a logical choice. However, if you live in an area with limited sunlight, it might be more advantageous to invest in additional batteries to store energy during periods of low sunlight.
It’s important to strike a balance between the number of solar panels and batteries to ensure optimal efficiency and cost-effectiveness. Consulting with a solar power expert can help you assess your specific needs and make an informed decision.
For instance, if you have a large household with high energy consumption and want to reduce your reliance on the grid, it would be more beneficial to prioritise more solar panels to generate enough electricity. On the other hand, if you live in an area with frequent power outages or limited sunlight, investing in additional batteries would provide you with backup power during such situations.

  1. General Rule: In many cases, installing solar panels on your property is considered ‘Permitted Development’ in the UK. This means you typically don’t need to apply for planning permission, provided certain conditions are met.
  2. Conditions for Permitted Development:
  • The solar panels should not protrude more than 200mm from the wall or roof surface.
  • If installing on the roof, panels should not be higher than the highest part of the roof (excluding the chimney).
  • Installations on a building within the grounds of a listed building or on a site designated as a scheduled monument are not permitted development.
  • In conservation areas or World Heritage Sites, panels should not be installed on the principal or side elevation of the property that faces onto a road.
  1. Flat Roofs: Special considerations apply for flat roofs. Panels should not be installed at an angle more than 5 degrees from the horizontal and should be sited so as not to be visible above the parapet or roof edge when viewed from ground level within the curtilage of the property.
  2. Leasehold and Shared Ownership Properties: If you’re living in a leasehold property or part of a shared ownership scheme, you might need permission from the freeholder or housing association.
  3. Building Regulations: While planning permission might not be necessary, your installation will need to comply with building regulations. This ensures the structure of the building can support the panels and that installations are carried out safely.
  4. Local Considerations: Some local councils have specific rules, so it’s always wise to check with your local planning authority to be sure of the regulations in your area.

Shading in your garden can indeed impact the performance of solar panels. Solar panels rely on sunlight to generate electricity, and shading can significantly reduce their efficiency and overall power output. Here’s what you need to know about shading and solar panel installations:
Impact of Shading
  1. Reduced Efficiency: Even partial shading on one panel can affect the performance of the entire system, especially if the panels are connected in a series.
  2. Hot Spots: Shading can cause ‘hot spots’, which not only reduce efficiency but can also damage the solar panels over time.
  3. Inconsistent Power Production: Shaded areas can lead to fluctuations in power production, which might affect the reliability of your solar energy supply.
Mitigation Strategies
  1. Site Assessment: Conduct a thorough site assessment to identify the areas that receive consistent sunlight throughout the day. Sometimes, repositioning the panels to a more sunlit part of the garden can minimise the impact of shading.
  2. Use of Microinverters or Power Optimizers: These devices are installed on each panel and help mitigate the impact of shading. They allow each panel to operate independently, ensuring that shaded panels don’t significantly affect the performance of unshaded ones.
  3. Pruning or Landscape Modification: If the shading is caused by trees or other vegetation, pruning or landscape modification might be a feasible solution.
  4. Panel Orientation and Tilt: Adjusting the orientation and tilt of the panels can also help maximise exposure to sunlight.
  5. Choosing the Right Panels: Some solar panels are designed to perform better in shaded conditions. Consult with a solar panel provider about the best options for your situation.
  • Seasonal Changes: Remember that the sun’s position changes with seasons, so a spot that’s sunny in summer might be shaded in winter.
  • Energy Requirements: If your energy needs are high and shading is unavoidable, you may need to compensate with more panels or consider alternative locations for installation.
  • Cost vs. Benefit Analysis: Implementing shading mitigation strategies can sometimes be costly. It’s important to weigh the costs against the expected benefits in energy yield.
While shading in your garden can be a challenge for solar panel efficiency, there are several ways to manage and mitigate its impact. A professional assessment by a solar installation company can provide the best strategies tailored to your specific situation, ensuring you get the most out of your solar panel investment.
Solar panels equipped with bypass diodes do help mitigate the effects of shading, but they don’t completely eliminate them. Understanding how bypass diodes work can help clarify their role in a solar panel system:

Function of Bypass Diodes
  • Minimising the Impact of Shading: When a part of a solar panel is shaded, the diodes bypass the shaded cells or sections. This allows the rest of the panel, or the other panels in the string, to continue functioning normally.
  • Prevention of Hot Spots: Bypass diodes also help prevent hot spots, which can occur in shaded areas of a solar panel and potentially cause damage over time.
  • Partial Solution: While bypass diodes reduce the impact of shading, they don’t eliminate it. The overall efficiency of the solar panel will still be reduced when parts of it are shaded.
  • Energy Loss: The shaded portion of the panel bypassed by the diode does not contribute to electricity generation, resulting in some energy loss.
Other Considerations
  • Panel Placement and Orientation: Proper placement and orientation of solar panels to minimise shading can be more effective than relying solely on bypass diodes.
  • Microinverters and Power Optimisers: Using microinverters or power optimisers can offer a more advanced solution to the shading problem. Unlike bypass diodes that work at the panel level, these devices optimise the output of each individual solar cell, thereby reducing the impact of shading even further.
Bypass diodes in solar panels are a useful feature to reduce the negative effects of shading, but they are not a complete solution. For optimal performance, it’s important to combine their use with strategic panel placement, and possibly the use of microinverters or power optimisers, especially in areas where shading is a significant concern. Consulting with solar installation experts like Glo Renewables can provide insights into the best approach for your specific situation.

South-Facing Roofs
  • Optimal Sunlight Exposure: In the northern hemisphere, south-facing roofs receive the most sunlight throughout the day, making them ideal for maximising solar energy production.
  • Best Efficiency: Panels on a south-facing roof generally produce the most electricity and offer the best return on investment.
Other Roof Orientations
  • East or West Facing: Roofs facing east or west can also be suitable for solar panels. East-facing roofs capture sunlight in the morning while west-facing roofs get sunlight in the afternoon. While the total energy production might be less than a south-facing roof, it can still be substantial.
  • North-Facing Roofs: In the UK, north-facing roofs receive the least amount of sunlight, making them the least ideal. However, with high-efficiency panels and if there’s no other option, they can still generate some electricity.
Other Considerations
  • Roof Pitch and Angle: The pitch of the roof also affects solar panel efficiency. A pitch of around 30 to 40 degrees is typically considered optimal in the UK.
  • Shading: Avoid areas shaded by trees, buildings, or other obstructions, as shading significantly reduces solar panel efficiency.
  • Panel Technology: Advances in solar panel technology mean that modern panels are more efficient, even in less-than-ideal orientations or light conditions.
  • Energy Needs and Goals: Consider your energy production goals. Even if your roof isn’t south-facing, you can still meet a significant portion of your energy needs with solar panels.
While a south-facing roof is ideal for solar panel installations in the UK, it’s not a necessity. East or west-facing roofs can also provide good results, especially with efficient solar panels and proper installation. 
It’s important to evaluate your specific situation, including roof orientation, angle, and shading, as well as your energy goals, to determine the best setup for your solar panel system. A professional solar installer can provide a detailed assessment and recommendations based on your unique circumstances.
