Worried about solar panels overheating?

While solar panels are designed to withstand high temperatures, excessive heat can affect their performance. Luckily, the UK’s moderate climate makes it an ideal location for solar panel installations. To prevent overheating, proper installation, regular maintenance, and ensuring proper airflow around the panels are crucial.

Curious if solar panels can power your UK home?

Absolutely! The MCS data reveals that around 1.2 million UK homes are already utilizing solar energy to power their residences. A solar panel-only installation can meet up to 75% of your energy needs, while adding a battery can increase this to 90%. Every home’s energy requirements are unique, so consulting with our qualified solar panel installers is key to determining the optimal solution for your property.

Can solar panels generate power at night?

Unfortunately, solar panels require sunlight to produce electricity through the photovoltaic effect, making night time generation impossible. However, fear not! With grid-connected systems, the National Grid can support your energy needs during the night. Alternatively, solar batteries connected to your solar panel system store excess energy for night time use.

Are solar panels self-cleaning?

While not entirely self-cleaning, solar panels possess some self-cleaning properties thanks to their hydrophilic and photocatalytic coating. Rain can help wash away accumulated dirt. Yet, in dry and dusty environments, regular maintenance ensures peak performance.

Anticipating greater solar panel efficiency?

Solar panel technology is rapidly advancing, with efficiency levels continually improving. Premium solar panels now reach around 22% module efficiency. Although further efficiency gains may be limited, ongoing research and development hold promise for the future.

Worried about power cuts?

In grid-tied systems, solar panels won’t function during power cuts to protect National Grid engineers. However, off-grid or hybrid systems with energy storage offer electricity during outages. Our team can guide you on installing an Emergency Power Supply for backup during power cuts.

Curious about smart meters and MCS Certificates?

While not mandatory for solar panel installation, smart meters enable access to energy tariffs and benefits. MCS Certificates are vital for Smart Export Guarantee payments. Our MCS-approved installers ensure quality and compliance for your solar panel installation.

Concerned about insurance and third-party ownership?

Solar panels are part of your building insurance, and proper notification to your insurer is essential. Solar panel companies no longer own your roof, and third-party ownership is a thing of the past.

Wondering if solar panels can power your hot tub?

es, solar panels can power a range of appliances, including hot tubs. Proper setup with high-voltage batteries and off-peak charging can support the electricity demands of your hot tub.
