Shedding Light on Solar PV: Answering Your Frequently Asked Questions

As the demand for renewable energy grows, Solar PV systems have emerged as a popular and sustainable solution. However, it’s natural to have questions before making the switch to solar power. In this article, we will address the most frequently asked questions about Solar PV systems, providing valuable insights and information to help you make informed decisions.

The Cost and Return:

One of the most common inquiries revolves around the cost and return on investment of Solar PV systems. Here’s what you need to know:

Solar PV systems’ cost varies based on factors such as system size, installation complexity, and component quality. On average, a 4kW Solar PV installation can range from £5,000 to £6,000, while adding batteries can cost an additional £3,000 to £6,000, depending on your requirements.

The payback period of Solar PV systems depends on several factors, including system size, location, and energy usage. On average, customers can expect a payback period of less than 10 years, with some systems reaching as low as 5 years.


Inquiring about batteries is another common topic when discussing Solar PV systems. Here are a couple of frequently asked questions:

Why have a battery instead of selling excess energy back to the grid? A battery allows you to store and utilize the energy you generate, maximizing self-consumption. It also enables you to power your home during periods of low solar production, such as in the evening or during power outages.

Can I add a battery to an existing Solar PV system? Yes, you can. An AC-coupled battery storage system can be retrofitted to your current installation, providing you with the benefits of energy storage.


Many homeowners wonder if their roofs are suitable for Solar installations. Here’s what you should know:

Solar panels can be fitted on roofs of various types, including older roofs and flat roofs, as long as they are in good condition. If you need future roof repairs, the panels can be easily removed and reinstalled once the repairs are complete.

The panels are securely attached to the roof using brackets designed to go under the tiles and screw into the rafters. This allows for easy removal and refitting when necessary.

Car Charging:

With the rise of electric vehicles, questions about charging cars with Solar systems are frequent. Consider the following:

Yes, you can charge your electric vehicle using the energy generated by your Solar PV system. By installing a car charging point alongside your Solar installation, you can enjoy the convenience of solar-powered vehicle charging.

This combination offers an eco-friendly and cost-effective solution, reducing your dependence on traditional fossil fuels and eliminating the need to queue at petrol stations.


Some may question the effectiveness of Solar PV systems in regions with limited sunshine. Here are important points to consider:

Solar PV systems still generate energy even on cloudy days. While their performance may be slightly reduced, they continue to produce electricity.

It’s good practice to install a higher-powered system than your inverter can handle to maximize energy generation. This compensates for peak sunshine hours and ensures a consistent energy output throughout the year.

Panel Upkeep:

Understanding how to maintain and care for solar panels is crucial for optimal performance. Consider the following:

To maximize energy generation, it’s recommended to clean the panels periodically to remove dirt, dust, and debris that can obstruct sunlight absorption.

Most solar panels come with a 25-year warranty, ensuring longevity and peace of mind.

To prevent pigeons or other pests from nesting under the panels, pigeon mesh can be installed, protecting both your panels and roof.


When considering Solar PV installations, it’s essential to choose qualified professionals. Here’s what to look for:

To register your panels correctly the company you choose must be MCS Registered which

Reputable installers undergo training and hold certifications such as ‘BPEC Solar PV Installation Training’ to ensure they have the necessary expertise.

Verify that your installer has completed specific manufacturer training courses to stay updated on product knowledge and installation practices.
