Background
Most UK homes that use solar power have panels fixed to their roof, which needs the household to own the property and have suitable roof space. This leaves out many people who rent their home or live in flats without access to a roof.
Causes
high household energy bills
Households across the UK have been looking for ways to cut their electricity costs. Plug-in solar offers a lower cost route into generating power compared with a full rooftop installation.
no rooftop access
People in flats or rented homes cannot usually fit rooftop solar panels because they do not own or control the roof. Balcony panels let them generate power from a balcony, terrace or shed roof instead.
existing use in Europe
Balcony solar systems, known as Balkonkraftwerk, are already popular in Spain and Germany. Their success there encouraged UK retailers and regulators to allow similar plug-in systems to be sold in Britain.
Effects
Primary
- Households can plug a solar panel directly into a wall socket to generate their own electricity.
- The power generated flows straight into the property's electrical circuit, powering appliances directly.
Secondary
- Households use less electricity bought from the grid when the panels are generating power.
- The National Energy System Operator can track the combined effect of many small systems on gas-fired power demand.
Social
- Renters and flat dwellers who could not previously install solar panels now have an option to generate power.
- Households are encouraged to shift tasks like washing to sunny periods to use the power as it is generated.
Economic
- Big retailers including Argos, Amazon, Currys, B&Q and Screwfix are expected to stock the systems.
- Households could lower their annual electricity bill by generating some of their own power.
Environmental
- Widespread use of small solar systems could reduce the need for gas-fired power generation or electricity imports.
Responses
Immediate
- Argos became the first UK retailer to sell the plug-in solar systems.
- Each solar system must be registered with the National Energy System Operator.
Long term
- Other major retailers are expected to begin stocking plug-in panels in the coming weeks.
- Consumer groups are calling for clear safety and planning information as more households consider buying the systems.
