Solar panel
installers

Typically, it takes 1-2 days to install solar panels on your home. Our team are based in Norfolk so they can be with you early in the morning without having to account for travel time from further afield. 

Typically 8-10% but can be as much as 12-14%. Join thousands of other homeowners and business owners across Norfolk and Suffolk who are enjoying the economic benefits of solar energy. 

We would expect 8-10 solar panels to fit on a house of this size. However, sometimes there is scope for more; there may be times where the design or structure of the property allows for fewer solar panels. In any case, our team will always conduct a thorough survey of the property to advise on the optimal number of solar panels that can be installed. 

No, but all of the products are rated at 0% VAT, which is a big saving and energy companies will buy your excess electricity off you under SEG (Solar Export Guarantee). You typically get around 15p per unit or kWh of exported electricity, which is more than half the value of what you buy it for; in other words, two units exported are worth more than one you buy—the true definition of 2 for the price of 1!

You can also be on certain tariffs with certain energy companies that will allow you to export to the grid at peak time and get paid for more than market value at around 27p per unit/kWh!

Yes, solar panels can add value to your home in the UK. They can increase the value of your home by 0.9–2% on average. However, the exact amount depends on several factors, including the location of your home. 

Factors that affect how much solar panels increase your home’s value

• Location: Homes in sunnier areas benefit more from solar panels. 
• Size: The size of your home can affect how much value solar panels add. 
• Current value: The current value of your home can affect how much value solar panels add. 
• Additional installations: Whether you have other installations like an electric vehicle charge point can affect how much value solar panels add. 

Other benefits of solar panels

• Energy savings: Solar panels can help you save money on your energy bills. 
• Aesthetic appeal: Solar panels can add a focal point to your living space. 
• Community impact: Solar panels can encourage others to consider renewable energy options. 

Research that supports solar panels increasing home value

• Solar Energy UK’s research found that solar panels can increase a home’s value by 0.9–2% 
• A study by BOXT found that solar panels could increase the value of a home by 14%  https://www.moneysupermarket.com/gas-and-electricity/value-of-efficiency/

Yes they do…But some higher-quality solar panels will work better in the winter than others due to their performance characteristics, so it’s important to use an installer like Wise Green Energy who understand this technical side of the equipment and can advise you correctly. Some panels work in shaded conditions better than others also.

• Cold temperatures can actually boost output, as the solar cells work better when cool.
• Solar panels can still capture sunlight when it’s overcast.
• Solar panels can be a worthwhile investment even during the colder months.

Yes, solar panels work off light, specifically the light from the sun, and generate electricity by converting the sun’s light energy into electrical energy through photovoltaic cells; even on cloudy days, they can produce power as long as there is visible light present. 

Key points about solar panels and light:

• Light is essential: Solar panels rely on light to function, not just heat from the sun. 
• Direct sunlight is best: While they can work in indirect light, solar panels generate the most electricity when exposed to direct sunlight. 
• Cloudy days still produce power: Even on cloudy days, solar panels can still generate electricity, although at a lower rate. 
• No light at night means no power: Solar panels cannot produce electricity at night as there is no sunlight. 

Yes, solar panels work in the UK during winter, but they produce less energy than in the summer. 

Why solar panels work less efficiently in winter

• Shorter days

The sun rises later and sets earlier, so there are fewer hours of daylight. 

• Lower sun

The sun is lower in the sky, so its light has to pass through more of the atmosphere. 

• More cloudy days

Winter tends to have more cloudy days, which can reduce the solar panels’ output. 

How to improve solar panel efficiency in winter 

• Adjust the tilt angle

A steeper tilt angle can help optimise the solar panels’ efficiency during the winter months.

• Perform basic maintenance

Clean the solar panels periodically with lukewarm water and non-abrasive brushes.

The number of solar panels you need to be self-sufficient depends on several factors, including: 

• Your home size: The number of bedrooms in your home 
• Your energy consumption: How much electricity you use annually 
• Your roof space: How much space you have on your roof for solar panels? 
• Your roof’s direction and pitch: A south-facing roof with a pitch of around 35 degrees is most efficient 
• Your electricity meter: Whether you have a single-phase or three-phase meter 
• Your budget: How much you can afford to spend on solar panels 

Estimates for the number of panels needed 

• A 1-2 bedroom home might need 4–8 panels
• A 2-3 bedroom home might need 8–13 panels
• A 4-5 bedroom home might need 13–16 panels

You can use a solar panel calculator to estimate how many panels you need. 

Benefits of having solar panels 

• You can reduce your energy bills
• You can be less vulnerable to power outages
• You can be less affected by energy price fluctuations
• You can future-proof your home for electricity-intensive upgrades

You can also use a smart meter to track your energy consumption and production. This can help you identify your peak hours for energy consumption and how they compare to when your solar panels are generating energy.
