Question 1

What is Solar PV and how does it work?

Accepted Answer

Solar Photovoltaic (PV) systems convert daylight directly into electricity using semiconductor materials. When daylight hits the solar panels, it creates an electric current. This current is then converted by an inverter into usable AC (alternating current) electricity for your home or business.

Question 2

How much space do I need for solar panels?

Accepted Answer

The space required depends on your energy needs and the type of panels used. A typical domestic solar PV system in the UK might require about 15-25 square metres of south-facing roof space. We conduct a detailed site survey to determine the optimal layout for your property.

Question 3

How long do solar panels last?

Accepted Answer

Most modern solar panels come with performance warranties of 20-25 years, guaranteeing a certain output efficiency over that period. The panels themselves can last much longer, often 30+ years, though their efficiency may gradually decrease over time.

Question 4

Why should I add battery storage to my solar PV system?

Accepted Answer

Battery storage allows you to store excess electricity generated by your solar panels during the day, rather than exporting it back to the grid. You can then use this stored energy during peak hours, at night, or on cloudy days, significantly increasing your self-consumption and reducing reliance on grid electricity.

Question 5

How long do battery storage systems last?

Accepted Answer

Battery storage systems typically come with warranties ranging from 5 to 15 years, often guaranteeing a certain number of charge/discharge cycles. The lifespan depends on usage patterns, temperature, and the specific battery technology.

Question 6

What is the benefit of having an EV charger at home?

Accepted Answer

Having a home EV charger provides unmatched convenience, allowing you to charge your electric vehicle overnight or whenever it's parked. It's often more cost-effective than public charging, especially when combined with off-peak electricity tariffs or solar PV.

Question 7

How long does it take to charge an EV at home?

Accepted Answer

Charging times vary greatly depending on the EV's battery size, the charger's power output, and the car's onboard charger capacity. A 7.4kW home charger can typically add around 25-30 miles of range per hour of charging.

Question 8

What is an EICR and why do I need one?

Accepted Answer

An Electrical Installation Condition Report (EICR) is a thorough inspection of your property's electrical systems to ensure they are safe and comply with current regulations. It's recommended for homeowners every 10 years and is a legal requirement for landlords at least every 5 years or at the start of a new tenancy.
