SOLAR PV FREQUENTLY ASKED QUESTIONS...

 What is Solar PV?: Solar PV (Photovoltaic) is a technology that converts sunlight directly into electricity using solar cells.

How do solar panels work?: Solar panels absorb sunlight and convert it into direct current (DC) electricity, which is then converted into alternating current (AC) by an inverter for use in homes or businesses.

What is the lifespan of a solar panel?: Most solar panels last 25–30 years with a gradual reduction in efficiency over time.

Can solar panels work in cloudy weather?: Yes, solar panels can generate electricity even on cloudy days, though their efficiency is reduced compared to sunny conditions.

 Do I need planning permission for solar panels in the UK?: Solar panels are generally considered permitted development, but planning permission might be needed for listed buildings or conservation areas.

What is the best roof orientation for solar panels?: South-facing roofs are ideal, but east- or west-facing roofs can also generate significant electricity.

Can solar panels be installed on flat roofs?: Yes, flat roofs can support solar panels using mounting systems that tilt the panels at an optimal angle.

 How efficient are solar panels?: Commercial solar panels typically have an efficiency of 15–20%, with some premium models reaching over 22%.

Do solar panels work at night?: No, solar panels require sunlight to generate electricity, but energy stored in batteries during the day can be used at night.

How much energy can I generate with solar panels?: A typical 4kW system in the UK can generate around 3,500–4,500 kWh per year, enough for the average household.

 How much does a solar PV system cost?: A standard residential system costs between £5,000 and £7,000, depending on size and quality.

How much can I save with solar panels?: Savings depend on energy usage and tariffs, but an average UK household can save £200–£400 annually on electricity bills.

What is the payback period for solar panels?: The payback period is typically 10–15 years, depending on energy savings and installation costs.

What happens to excess electricity?: Excess electricity can be exported to the grid under the UK’s Smart Export Guarantee (SEG), earning you money.

Do I need a battery with my solar panels?: No, but batteries can store surplus energy for use at night or during power outages.

Can I go completely off-grid with solar panels?: It’s possible, but it requires a large system and significant battery storage, which can be costly.

 How often do solar panels need cleaning?: Panels generally require minimal maintenance, but cleaning them every 1–2 years can optimize performance, especially in dusty or polluted areas.

What if a solar panel gets damaged?: Most panels are built to withstand harsh weather, but warranties often cover manufacturing defects or damage under normal use.

 Do solar panels work in the UK?: Yes, the UK has sufficient sunlight for solar panels to be effective, even in regions with less sun exposure.

Are solar panels affected by snow?: Snow can temporarily block sunlight, but panels are usually mounted at an angle that allows snow to slide off.

 Can I add more panels later?: Yes, most systems are scalable, but ensure your inverter and mounting structure can support additional capacity.

Can solar panels charge an electric vehicle (EV)?: Yes, solar energy can be used to charge EVs, often through a dedicated EV charger connected to the system.
